GLP-1 Prescribing Decisions: Compounded or Brand-Name?
Both Eli Lilly and Novo Nordisk have asked the Food and Drug Administration (FDA) to place their GLP-1 medications, tirzepatide and semaglutide, on its Demonstrable Difficulties for Compounding or DDC Lists, which would prohibit compounding the medications. Lawsuits are another issue. The Outsourcing Facility Association, a trade group, filed a lawsuit against the FDA, calling on it to restore tirzepatide to the shortage list after the FDA removed it on October 2, despite pharmacies still experiencing shortages, according to the association. The FDA is reevaluating the decision and won’t take action against compounders in the interim, with a joint status report scheduled for November 21.
In the midst of the lawsuits and pending decisions, healthcare providers are taking a variety of approaches when they need to decide between compounded vs brand-name GLP-1s for obesity treatment. The Alliance for Pharmacy Compounding, another trade group, offers a number of suggestions for doctors faced with compound or brand-name decisions and has a website tool to be sure a compounding pharmacy meets standards.
According to the FDA, a drug may be compounded for a patient who can’t be treated with an FDA-approved medication, such as a patient who has an allergy to a certain ingredient and needs medication to be made without it, or for a medication that appears on the FDA Drug Shortages List.
Here’s how five healthcare providers make the decision.
Physicians Weigh in
Hard pass: “I have no experience with compounded formulations by choice,” said W. Timothy Garvey, MD, MACE, an obesity specialist and the Charles E. Butterworth Jr professor and university professor at the University of Alabama at Birmingham. “I think our patients deserve better.”
However, he acknowledged: “This is a difficult situation when there is a lack of access to medications patients need.” Even so, “online prescriptions [for compounded medications] are often done without an evaluation for obesity complications and related diseases and ongoing active management, making a complications-centric approach to care impossible.”
That’s not the optimal approach to treating obesity or other chronic diseases, he said in an interview.
Rather than prescribe compounded GLP-1s for weight loss, he said, other options exist. Among them: Prescribe Ozempic off label for obesity.
“Plus, we have a good first-generation obesity medication — phentermine/topiramate — that gets close to 10% weight loss on average in clinical trials that is available and less expensive.”
Other options, he said, are to switch to lower doses of the brand name that may be available until the treatment dose needed is out of shortage status or, the less desirable option, wait for availability, which means the patient may be off the medication for a month or more.
He acknowledged none of these options solves “the problem of high costs [for brand-name drugs] and lack of insurance coverage.”
In agreement is Caroline Apovian, MD, codirector of the Center for Weight Management and Wellness at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, both in Boston, Massachusetts.
“Doctors who are obesity medicine specialists like myself in academic centers do not prescribe compounded semaglutide or tirzepatide,” she said.
Many of the compounded prescriptions, she said, come from telehealth virtual–only companies interested in profits.
Brand names preferred: “Brand-name versions as far as I’m concerned are always preferred,” said Sarah Stombaugh, MD, an obesity medicine and family medicine physician in Charlottesville, Virginia. She terms it irresponsible for a prescriber to give a patient a compounded GLP-1 if the patient has prescription coverage and the brand name is available.
Her approach: She first checks the patients’ coverage. Do they have coverage for these medications for obesity? If so, she said, she will do a prior authorization to get the brand name approved. If a brand name is available but not covered, she explores other options. One is the cash pay option for Zepbound in vials. It’s more affordable than the typical $1000 cash price for the brand name GLP-1s but still pricey, at about $400-$549 for lower doses.
She looks at drug makers’ discount coupons, or whether a patient with a history of cardiovascular issues might qualify for coverage on Wegovy. Another option is to give the patient a prescription for Mounjaro or Ozempic to fill from a Canadian pharmacy for about $400 a month.
“I think a lot of people jump quickly to compounding,” she said.
She views it as a last resort and reminds other healthcare providers that the compounded medications aren’t cheap, either, typically costing $100-$500 a month depending on dosage. And, she said, “we have many who get the brand name for $25 a month [by using discount cards and insurance coverage].”
When prescribing a compounded medication is necessary, it’s important for healthcare providers to know that the quality of the compounding pharmacies varies greatly, Stombaugh said. A prescriber needs to pick the compounding pharmacy, not the patient, and needs to vet it, she said, asking about protocols it follows for sterility and for chemical analysis, for instance.
Stombaugh is hopeful that several new medications under study and now in phase 3 trials will soon provide enough competition to drive down the price of the current brand-name GLP-1s.
History of mistrust: Robert Dubin, MD, associate professor of research at the Pennington Biomedical Research Center at Louisiana State University, Baton Rouge, and program director for its obesity medicine fellowship, sees a role for compounding and has for several years, but acknowledged that many in his community are against it.
He estimates that about 75% of his colleagues in the Baton Rouge area are opposed to prescribing compounded GLP-1s. He chalks it up to a “track record of distrust,” based on reports of infractions called out by the FDA for some compounding pharmacies as well as physicians not being familiar with the process.
Dubin said he will prescribe a compounded medication if the brand name isn’t available. Cost is also a consideration. “If there’s not a problem with availability and there’s not a problem with cost, then why compound?”
For anyone considering prescribing compounded GLP-1s, he said, “The first step, I believe, is having a relationship with the compounding pharmacy. If you don’t have that, it could be very difficult. We don’t want to send people to a black hole, and we aren’t sure what is going to happen.” He urges colleagues to educate themselves about compounding pharmacies.
Official shortage list vs real world: “The official shortage list doesn’t always reflect the real world,” said Amanda Guarniere, NP, a nurse practitioner with a self-pay telehealth and in-person practice and director of growth for Collaborating Docs, a service based in Arlington, Virginia, that pairs nurse practitioners with supervising physicians.
“When Zepbound and Mounjaro came off the [FDA] shortage list a few weeks ago, patients were still calling around and couldn’t find it in their county.”
It’s important to vet compounding pharmacies before dealing with them, she said.
“I have accounts with two compounding pharmacies who I trust,” she said. She’s researched their quality control provided and is comfortable with their standards. When appropriate, the cost savings of compounded GLP-1s over brand name is “pretty significant,” with compounded medicine costs about 20% of brand-name costs.
When the brand name is back, how might a prescriber still write a prescription for a compounded version? “Compounded versions are typically compounded with something else,” Guarniere said.
For instance, compounded tirzepatide often includes vitamin B12 and other B vitamins, which may help with the side effect of nausea. So a prescriber might decide that the compounded prescription is more appropriate and justified because the patient would benefit from the additive, she said.
What Else to Know: Alliance Views
On November 7, the Alliance for Pharmacy Compounding, a trade group, responded to Lilly’s request to put tirzepatide on the “demonstrably difficult to compound (DDC)” list, asking the FDA to deny it. The group also took issue with criticism of compounded GLP-1s from the Novo Nordisk CEO.
The alliance offers perspective and a number of suggestions for doctors faced with compound or brand-name decisions, including using its website tool called “Is It Legit?” to be sure a compounding pharmacy meets standards.
“When these [GLP-1] drugs came out, I don’t think anybody anticipated them to be such blockbusters,” said Tenille Davis, PharmD, a board-certified sterile compounding pharmacist and chief advocacy officer for the Alliance for Pharmacy Compounding. Shortages have plagued the GLP-1s since their approvals, with Wegovy approved on June 4, 2021, and Eli Lilly’s Zepbound on November 8, 2023.
The proposed “Demonstrably Difficult to Compound (DDC)” rule, published in March 2024, aims to finalize the six criteria for a medication to land on that list, she said. No drugs are currently on this list, Davis said.
For now, she said, prescribers faced with a compound vs brand-name decision should be aware of the pending lawsuit concerning tirzepatide and that the FDA has said it will cease most enforcement action until 2 weeks after it reviews the decision to remove the medication from the shortage list and issues a new determination.
Davis suggests prescribers have conversations now with their patients about their options and to tell them it may be necessary to transition from the compounded medicines to brand name. “This may require insurance prior authorizations, so if they are going to transition from compounded tirzepatide to Zepbound and Mounjaro, it’s good to start the process sooner rather than later so there isn’t an interruption in care.”
Earlier in 2024, the three leading obesity organizations issued a statement, advising patients that they do not recommend the use of compounded GLP-1s.

How to Manage Patients on GLP-1s Before Surgery
, as does the US Food and Drug Administration’s (FDA’s) labeling for the drugs. The changes can be challenging to keep up with, and endocrinologists seem to be making their own decisions based on clinical experience and their interpretations of the potential impact and value of the emerging information.
The latest FDA label change warns about the risk for pulmonary aspiration but notes “insufficient” data to inform recommendations to mitigate the risk in vulnerable patients. Yet, the latest multi-society guidance, led by the American Society of Anesthesiologists (ASA) and based on consensus, not evidence, has nuanced advice for managing patients at risk.
Does the FDA’s label change make a difference regarding the multi-society guidance, which was published earlier? “The answer is no,” Girish Joshi, MD, vice chair, ASA Committee on Practice Parameters, told this news organization. “The concern of increased pulmonary aspiration in patients who are on GLP-1 receptor agonists has been known, and that concern still exists. So, we started with not an assumption but the premise that patients on GLP-1 receptor agonists are at a higher risk of aspiration during sedation, analgesia, and/or general anesthesia. The FDA basically confirms what we say in the guidance.”
Joshi, professor in the Anesthesiology and Pain Management Department at UT Southwestern Medical Center, Dallas, aimed to make the guidance, which was published simultaneously in several society journals, more implementable with a letter to the editor of Anesthesiology. The key, he said, is to identify patients at higher risk for aspiration; all others would follow treatment as usual.
The letter highlights three overarching recommendations and then expands upon them: Standardized preoperative assessment for risk for delayed gastric emptying (yes/no); selective preoperative care plan based on delayed gastric emptying assessment and shared decision-making; and on the day of the procedure, reassess for delayed gastric emptying and mitigate risk if there is clinical concern.
But it seems as though, for now, endocrinologists are managing these patients as they see fit, within the parameters of any institutional guidance requirements. Here is what they said about their practice:
Amy E. Rothberg, MD, DABOM, director of the Weight Management Program & Rewind at the University of Michigan, Ann Arbor, Michigan, said, “I think it makes sense to inform our patients of the labeling and rare but potential adverse effects if they intend to undergo anesthesia for a scheduled procedure/surgery. There is never no risk of aspiration during anesthesia.”
“I find it a bit curious that ASA implies that those who experience GI side effects are more likely than those who do not to have this potential risk. I doubt there is evidence that those without GI side effects are necessarily ‘safer’ and a study to determine that is unlikely to take be conducted.”
“My institution does require a 1-week pause on GLP-1s for those undergoing anesthesia for surgery,” she added. “That’s not evidence-based either, but probably reduces the risk of aspiration during anesthesia — but I don’t know what the actual denominator is for aspiration in those who continued vs those who took a pause from GLP-1s. Pausing does certainly (anecdotally) increase the traffic of communications between physicians and their patients about what to do in the interval.”
Anne Peters, MD, a professor of clinical medicine and a clinical scholar at the Keck School of Medicine of the University of Southern California, Los Angeles, said, “The FDA label change is a warning that really doesn’t say exactly who on GLP-1 RAs is at highest risk or what to do, and if any intervention has been shown to help. The ASA recommendations seem much more nuanced and practical, including point-of-care gastric ultrasound to see if there is retained food/fluid prior to surgery.”
“In my practice, I individualize what I say, depending on the person and the circumstance,” she said. “Mostly, I have people hold one dose before planned surgery, so they have been 10 days at least without a dose. But if worried about gastrointestinal symptoms or gastroparesis, I have them do a clear liquid diet for 24 hours presurgery. Or at least avoid heavy fat meals the day before.”
“There is a risk of aspiration with anything that slows gastric emptying — maybe even in patients with gastroparesis at baseline due to physiologic, not pharmacological, reasons — and anesthesiologists should be aware of the need to assess patients individually.”
Michael A. Weintraub, MD, of NYU Langone Health Diabetes & Endocrine Associates in New York City, observed, “The risk of a pulmonary aspiration event with GLP-1 medication is quite rare, but not zero. On the other hand, stopping the GLP-1 can cause hyperglycemia or rebound weight gain. Furthermore, it can become complicated to restart GLP1 dosing, particularly given the existing medication shortages.”
“In most cases, stopping a weekly GLP-1 medication 1 week prior to the procedure minimizes the risks of pulmonary aspiration and prevents any worsening hyperglycemia or weight gain,” he said. However, taking the drug 7 days prior to the procedure is optimal. “That way, they would be due for the next dose on the day of the procedure, and taking it the day following procedure minimizes disruption in their once-weekly regimen.”
Malini Gupta, MD, director of G2Endo Endocrinology & Metabolism, Memphis, Tennessee, advised that physicians weigh the risk of stopping the medication (which can cause a glycemic spike) vs risk for aspiration.
“In my opinion, all patients should follow a strict liquid diet or NPO status prior to a surgery to further decrease the risk of aspiration,” she said. “I generally hold the GLP-1 RA for a week before a surgery. If additional glycemic control is necessary, I will add to or adjust one of the patient’s other diabetes medications.”
Jaime Almandoz, MD, associate professor of medicine and medical director of the Weight Wellness Program in Dallas, said, “As endocrinologists, we typically rely on our anesthesia colleagues for guidance on perioperative management.

“For those managing diabetes with GLP-1 therapies, it is crucial to establish a blood sugar management plan while off these medications, especially during fasting or postoperative periods, which can be further influenced by many factors, including nausea, pain medications, and antibiotics after the procedure.”
Joshi added that at Parkland Hospital in Dallas, “we do a huge number of cases using the same information. We identify patients who are at risk, and then we tell our proceduralists and our surgeons if they’re in the escalating phase of the dosing or if they have GI symptoms; don’t even schedule them as an elective case; wait till the escalation phase is over and then schedule them.”
“That way,” he said, “it becomes logistically easy to manage because the recommendation from the group is that patients who are at higher risk should receive a 24-hour liquid diet — the same as colonoscopy. But sometimes it can be challenging to do so.”

, as does the US Food and Drug Administration’s (FDA’s) labeling for the drugs. The changes can be challenging to keep up with, and endocrinologists seem to be making their own decisions based on clinical experience and their interpretations of the potential impact and value of the emerging information.
The latest FDA label change warns about the risk for pulmonary aspiration but notes “insufficient” data to inform recommendations to mitigate the risk in vulnerable patients. Yet, the latest multi-society guidance, led by the American Society of Anesthesiologists (ASA) and based on consensus, not evidence, has nuanced advice for managing patients at risk.
Does the FDA’s label change make a difference regarding the multi-society guidance, which was published earlier? “The answer is no,” Girish Joshi, MD, vice chair, ASA Committee on Practice Parameters, told this news organization. “The concern of increased pulmonary aspiration in patients who are on GLP-1 receptor agonists has been known, and that concern still exists. So, we started with not an assumption but the premise that patients on GLP-1 receptor agonists are at a higher risk of aspiration during sedation, analgesia, and/or general anesthesia. The FDA basically confirms what we say in the guidance.”
Joshi, professor in the Anesthesiology and Pain Management Department at UT Southwestern Medical Center, Dallas, aimed to make the guidance, which was published simultaneously in several society journals, more implementable with a letter to the editor of Anesthesiology. The key, he said, is to identify patients at higher risk for aspiration; all others would follow treatment as usual.
The letter highlights three overarching recommendations and then expands upon them: Standardized preoperative assessment for risk for delayed gastric emptying (yes/no); selective preoperative care plan based on delayed gastric emptying assessment and shared decision-making; and on the day of the procedure, reassess for delayed gastric emptying and mitigate risk if there is clinical concern.
But it seems as though, for now, endocrinologists are managing these patients as they see fit, within the parameters of any institutional guidance requirements. Here is what they said about their practice:
Amy E. Rothberg, MD, DABOM, director of the Weight Management Program & Rewind at the University of Michigan, Ann Arbor, Michigan, said, “I think it makes sense to inform our patients of the labeling and rare but potential adverse effects if they intend to undergo anesthesia for a scheduled procedure/surgery. There is never no risk of aspiration during anesthesia.”
“I find it a bit curious that ASA implies that those who experience GI side effects are more likely than those who do not to have this potential risk. I doubt there is evidence that those without GI side effects are necessarily ‘safer’ and a study to determine that is unlikely to take be conducted.”
“My institution does require a 1-week pause on GLP-1s for those undergoing anesthesia for surgery,” she added. “That’s not evidence-based either, but probably reduces the risk of aspiration during anesthesia — but I don’t know what the actual denominator is for aspiration in those who continued vs those who took a pause from GLP-1s. Pausing does certainly (anecdotally) increase the traffic of communications between physicians and their patients about what to do in the interval.”
Anne Peters, MD, a professor of clinical medicine and a clinical scholar at the Keck School of Medicine of the University of Southern California, Los Angeles, said, “The FDA label change is a warning that really doesn’t say exactly who on GLP-1 RAs is at highest risk or what to do, and if any intervention has been shown to help. The ASA recommendations seem much more nuanced and practical, including point-of-care gastric ultrasound to see if there is retained food/fluid prior to surgery.”
“In my practice, I individualize what I say, depending on the person and the circumstance,” she said. “Mostly, I have people hold one dose before planned surgery, so they have been 10 days at least without a dose. But if worried about gastrointestinal symptoms or gastroparesis, I have them do a clear liquid diet for 24 hours presurgery. Or at least avoid heavy fat meals the day before.”
“There is a risk of aspiration with anything that slows gastric emptying — maybe even in patients with gastroparesis at baseline due to physiologic, not pharmacological, reasons — and anesthesiologists should be aware of the need to assess patients individually.”
Michael A. Weintraub, MD, of NYU Langone Health Diabetes & Endocrine Associates in New York City, observed, “The risk of a pulmonary aspiration event with GLP-1 medication is quite rare, but not zero. On the other hand, stopping the GLP-1 can cause hyperglycemia or rebound weight gain. Furthermore, it can become complicated to restart GLP1 dosing, particularly given the existing medication shortages.”
“In most cases, stopping a weekly GLP-1 medication 1 week prior to the procedure minimizes the risks of pulmonary aspiration and prevents any worsening hyperglycemia or weight gain,” he said. However, taking the drug 7 days prior to the procedure is optimal. “That way, they would be due for the next dose on the day of the procedure, and taking it the day following procedure minimizes disruption in their once-weekly regimen.”
Malini Gupta, MD, director of G2Endo Endocrinology & Metabolism, Memphis, Tennessee, advised that physicians weigh the risk of stopping the medication (which can cause a glycemic spike) vs risk for aspiration.
“In my opinion, all patients should follow a strict liquid diet or NPO status prior to a surgery to further decrease the risk of aspiration,” she said. “I generally hold the GLP-1 RA for a week before a surgery. If additional glycemic control is necessary, I will add to or adjust one of the patient’s other diabetes medications.”
Jaime Almandoz, MD, associate professor of medicine and medical director of the Weight Wellness Program in Dallas, said, “As endocrinologists, we typically rely on our anesthesia colleagues for guidance on perioperative management. In light of emerging guidelines for holding GLP-1 medications, we also recommend patients adopt a liquid diet 24 hours prior to surgery, along with the fasting protocol.”
“For those managing diabetes with GLP-1 therapies, it is crucial to establish a blood sugar management plan while off these medications, especially during fasting or postoperative periods, which can be further influenced by many factors, including nausea, pain medications, and antibiotics after the procedure.”

Continuous Glucose Monitors for All? Opinions Remain Mixed
The recent US Food and Drug Administration (FDA) clearance of two over-the-counter (OTC) continuous glucose monitors (CGMs) — Dexcom’s Stelo and Abbott’s Lingo — has sparked interest in potentially expanding their use to those without diabetes or prediabetes.
There are several valid questions about how the general population might benefit from CGMs. Can they motivate those struggling with overweight to shed pounds? Would they prompt users to follow more healthful eating patterns? Can they act as a canary in the coal mine, alerting users to prediabetes?
The short answer to these questions is, we don’t know.
“Glucose levels fluctuate in everyone in response to meals, exercise, stress, etc, but there has been no credible research to support CGM use by most people who do not have diabetes,” Jill Crandall, MD, chief of endocrinology at Albert Einstein College of Medicine and Montefiore Health System in New York City, said in an interview.
“The utility of CGM for people without diabetes hasn’t been established and the drive to market CGM as an OTC device seems largely driven by financial considerations,” Crandall said. She advocates instead for a strategy directed at more meaningful objectives.
“For now, efforts should be focused on making CGMs available to patients who will clearly benefit — ie, people with diabetes, especially those who are using insulin and those who are struggling to achieve desired levels of glucose control.”
Nicole Spartano, PhD, assistant professor of medicine in endocrinology, diabetes, nutrition and weight management at Boston University’s Chobanian & Avedisian School of Medicine in Massachusetts, agreed with this assessment.
“It is definitely too early to make recommendations for patients without diabetes based on their CGM data,” said Spartano, who also serves as the director of the Glucose Monitoring Station at the Framingham Heart Study in Framingham, Massachusetts. “We simply do not have enough follow-up data to tell us which CGM metrics are associated with higher risk for disease.”
Spartano served as the lead author of a recent study showing time spent in various CGM ranges in a large cohort of individuals without diabetes using the Dexcom G6 Pro model. In the future, she said the data may be used to establish reference ranges for clinicians and individuals.
“We are working on another paper surveying diabetologists and CGM experts about how they interpret CGM reports from individuals without diabetes,” she said in an interview. Although the data are not yet published, Spartano said, “we are finding that clinicians are currently very discordant in how they interpret these reports.”
Potential Benefits Right Now
Satish Garg, MD, director of the Adult Clinic at the Barbara Davis Center for Diabetes at the University of Colorado Anschutz Medical Campus, Aurora, and editor-in-chief of Diabetes Technology & Therapeutics, is convinced that glucose should be considered another vital sign, like blood pressure, pulse rate, respiration rate, and body temperature. Therefore, he sees the use of a CGM in people without diabetes as a way to build awareness and perhaps prompt behavior modification.
“Someone with an A1c of 4.9 on a normal day may notice that they’ve gained a little bit of weight, and if they use an OTC CGM and start seeing changes, it might help them to modulate their diet themselves, whether they see a dietitian or not,” Garg said.
He gave the example of “a natural behavioral change” occurring when someone using a CGM declines to eat a post-meal dessert after seeing their blood glucose had already risen to 170.
Wearing a CGM also has the potential to alert the user to high blood glucose, leading them to an earlier diagnosis of prediabetes or diabetes, Shichun Bao, MD, PhD, Diabetes Technology Program Leader at the Vanderbilt Eskind Diabetes Clinic of Vanderbilt University in Nashville, Tennessee, said in an interview. She has had cases where a family member of someone with diabetes used the patient’s fingerstick meter, found that their glucose was 280, and self-diagnosed with diabetes.
“It’s the same thing with the CGM,” she said. “If they somehow did not know they have diabetes and they wear a CGM and it shows their sugar is high, that will help them to know to see their provider to get a diagnosis, get treated, and track progression.”
Given the shortage of endocrinologists and long waits for appointments in the United States and elsewhere, it is very likely that primary care physicians will be the ones fielding questions from individuals without diabetes interested in purchasing an OTC CGM. Internist Douglas Paauw, MD, a professor at the University of Washington School of Medicine, Seattle, said in an interview that, for his practice, “the benefits outweigh some of the limitations.”
“I don’t really think somebody who doesn’t have diabetes needs to be using a CGM all the time or long term,” he said. “But I have used it in a few people without diabetes, and I think if someone can afford to use it for 2-4 weeks, especially if they’ve been gaining weight, then they can really recognize what happens to their bodies when they eat certain foods.”
Paauw added that CGMs are a more effective means of teaching his patients than them receiving a lecture from him on healthy eating. “There’s nothing like immediate feedback on what happens to your body to change behavior.”
Similarly, William Golden, medical director at Arkansas Medicaid and professor of medicine and public health at the University of Arkansas for Medical Sciences, Little Rock, said in an interview that “it is difficult to justify coverage for CGMs on demand — but if people want to invest in their own devices and the technology motivates them to eat better and/or lose weight, then there are benefits to be had.”
Potential Downsides
Although it may seem simple to use an OTC CGM to measure blood glucose on the fly, in the real world it can take patients time to understand these devices, “especially the first day or so, when users are going to get false lows,” Bao said. “Clinicians need to tell them if you don’t feel like your sugar is low and the device says it’s low, whether they do or don’t have diabetes, they should do a fingerstick glucose test to confirm the low before rushing to take in sugar. On the other hand, if they drink a lot of juice, their sugar will go high. So, it can create problems and false results either way.”
Many factors affect glucose, she said. “When you’re sick, glucose can go high, and when you’re very sick, in the ICU, sometimes it can be low. It depends on the situation.” Bao noted that certain vitamins and drugs can also interfere with readings.
Bao doesn’t see value in having people without diabetes monitor their glucose continuously. “If they want to see what foods or exercise do to their body, they will probably benefit from a short trial to gain some insight; otherwise, they’re wasting money,” she said.
Another potential downside is that there’s no head-to-head comparison data with the approved devices, Garg said. “But it’s clear to us that Stelo’s range is very narrow, 70 to 200, whereas the Lingo ranges are pretty much full, from 40 to 400 or 55 to 400. So, we don’t know the accuracy of these sensors.”
Golden observed that for certain patients, CGMs may lead to psychological distress rather than providing a sense of control over their blood glucose levels.
“I have had a nondiabetic patient or two that obsessed about their blood sugars and a device would only magnify their anxiety/neurosis,” he said. “The bottom line is that it’s a tool for a balanced approach to health management, but the daily results must be kept in perspective!”
Educate Patients, Primary Care Physicians
To maximize potential benefits for patients without diabetes, clinicians need to be well trained in the use and interpretation of results from the devices, Bao said. They can then better educate their patients, including discussing with them possible pitfalls surrounding their use.
“For example, a patient may see that their blood glucose, as measured by a fingerstick, is 95, whereas the CGM says 140, and ask, ‘Which one do I trust?’ ”
This is where the patient can be educated about the difference between interstitial glucose, as measured by the CGM, and blood glucose, as measured by the fingerstick. Because it takes about 15 minutes for blood glucose to get to the interstitial tissue, there’s lag time, and the two measurements will differ.
“A discrepancy of 20% is totally acceptable for that reason,” Bao said.
She has also seen several examples where patients were misled by their CGM when its censor became dislodged.
“Sometimes when a sensor has moved, the patient may push it back in because they don’t want to throw it away. But it doesn’t work that way, and they end up with inaccurate readings.”
At a minimum, Bao added, clinicians and patients should read the package insert but also be aware that it doesn’t list everything that might go wrong or interfere with the device’s accuracy.
Manufacturers of OTC devices should be training primary care and family practice doctors in their use, given the expected “huge” influx of patients wanting to use them, according to Garg.
“If you are expecting endos or diabetes specialists to see these people, that’s never going to happen,” he said. “We have a big shortage of these specialists, so industry has to train these doctors. Patients will bring their doctor’s data, and the clinicians need to learn the basics of how to interpret the glucose values they see. Then they can treat these patients rather than shipping all of them to endos who likely are not available.”
Paauw agreed that CGM training should be directed largely toward primary care professionals, who can help their under-resourced endocrinologist colleagues from seeing an uptick in “the worried well.”
“The bottom line is that primary care professionals do need to understand the CGM,” he said. “They do need to get comfortable with it. They do need to come up with opinions on how to use it. The public’s going to be using it, and we need to be competent in it and use our subspecialists appropriately.”
Spartano received funding for an investigator-initiated research grant from Novo Nordisk unrelated to the cited CGM studies. Garg , Bao, Paauw, Golden, and Crandall declared no relevant conflicts of interest.

The recent US Food and Drug Administration (FDA) clearance of two over-the-counter (OTC) continuous glucose monitors (CGMs) — Dexcom’s Stelo and Abbott’s Lingo — has sparked interest in potentially expanding their use to those without diabetes or prediabetes.
There are several valid questions about how the general population might benefit from CGMs. Can they motivate those struggling with overweight to shed pounds? Would they prompt users to follow more healthful eating patterns? Can they act as a canary in the coal mine, alerting users to prediabetes?
The short answer to these questions is, we don’t know.
“Glucose levels fluctuate in everyone in response to meals, exercise, stress, etc, but there has been no credible research to support CGM use by most people who do not have diabetes,” Jill Crandall, MD, chief of endocrinology at Albert Einstein College of Medicine and Montefiore Health System in New York City, said in an interview.
“The utility of CGM for people without diabetes hasn’t been established and the drive to market CGM as an OTC device seems largely driven by financial considerations,” Crandall said. She advocates instead for a strategy directed at more meaningful objectives.
“For now, efforts should be focused on making CGMs available to patients who will clearly benefit — ie, people with diabetes, especially those who are using insulin and those who are struggling to achieve desired levels of glucose control.”
Nicole Spartano, PhD, assistant professor of medicine in endocrinology, diabetes, nutrition and weight management at Boston University’s Chobanian & Avedisian School of Medicine in Massachusetts, agreed with this assessment.
“It is definitely too early to make recommendations for patients without diabetes based on their CGM data,” said Spartano, who also serves as the director of the Glucose Monitoring Station at the Framingham Heart Study in Framingham, Massachusetts. “We simply do not have enough follow-up data to tell us which CGM metrics are associated with higher risk for disease.”
Spartano served as the lead author of a recent study showing time spent in various CGM ranges in a large cohort of individuals without diabetes using the Dexcom G6 Pro model. In the future, she said the data may be used to establish reference ranges for clinicians and individuals.
“We are working on another paper surveying diabetologists and CGM experts about how they interpret CGM reports from individuals without diabetes,” she said in an interview. Although the data are not yet published, Spartano said, “we are finding that clinicians are currently very discordant in how they interpret these reports.”
Potential Benefits Right Now
Satish Garg, MD, director of the Adult Clinic at the Barbara Davis Center for Diabetes at the University of Colorado Anschutz Medical Campus, Aurora, and editor-in-chief of Diabetes Technology & Therapeutics, is convinced that glucose should be considered another vital sign, like blood pressure, pulse rate, respiration rate, and body temperature. Therefore, he sees the use of a CGM in people without diabetes as a way to build awareness and perhaps prompt behavior modification.
“Someone with an A1c of 4.9 on a normal day may notice that they’ve gained a little bit of weight, and if they use an OTC CGM and start seeing changes, it might help them to modulate their diet themselves, whether they see a dietitian or not,” Garg said.
He gave the example of “a natural behavioral change” occurring when someone using a CGM declines to eat a post-meal dessert after seeing their blood glucose had already risen to 170.
Wearing a CGM also has the potential to alert the user to high blood glucose, leading them to an earlier diagnosis of prediabetes or diabetes, Shichun Bao, MD, PhD, Diabetes Technology Program Leader at the Vanderbilt Eskind Diabetes Clinic of Vanderbilt University in Nashville, Tennessee, said in an interview. She has had cases where a family member of someone with diabetes used the patient’s fingerstick meter, found that their glucose was 280, and self-diagnosed with diabetes.
“It’s the same thing with the CGM,” she said. “If they somehow did not know they have diabetes and they wear a CGM and it shows their sugar is high, that will help them to know to see their provider to get a diagnosis, get treated, and track progression.”
Given the shortage of endocrinologists and long waits for appointments in the United States and elsewhere, it is very likely that primary care physicians will be the ones fielding questions from individuals without diabetes interested in purchasing an OTC CGM. Internist Douglas Paauw, MD, a professor at the University of Washington School of Medicine, Seattle, said in an interview that, for his practice, “the benefits outweigh some of the limitations.”
“I don’t really think somebody who doesn’t have diabetes needs to be using a CGM all the time or long term,” he said. “But I have used it in a few people without diabetes, and I think if someone can afford to use it for 2-4 weeks, especially if they’ve been gaining weight, then they can really recognize what happens to their bodies when they eat certain foods.”
Paauw added that CGMs are a more effective means of teaching his patients than them receiving a lecture from him on healthy eating. “There’s nothing like immediate feedback on what happens to your body to change behavior.”
Similarly, William Golden, medical director at Arkansas Medicaid and professor of medicine and public health at the University of Arkansas for Medical Sciences, Little Rock, said in an interview that “it is difficult to justify coverage for CGMs on demand — but if people want to invest in their own devices and the technology motivates them to eat better and/or lose weight, then there are benefits to be had.”
Potential Downsides
Although it may seem simple to use an OTC CGM to measure blood glucose on the fly, in the real world it can take patients time to understand these devices, “especially the first day or so, when users are going to get false lows,” Bao said. “Clinicians need to tell them if you don’t feel like your sugar is low and the device says it’s low, whether they do or don’t have diabetes, they should do a fingerstick glucose test to confirm the low before rushing to take in sugar. On the other hand, if they drink a lot of juice, their sugar will go high. So, it can create problems and false results either way.”
Many factors affect glucose, she said. “When you’re sick, glucose can go high, and when you’re very sick, in the ICU, sometimes it can be low. It depends on the situation.” Bao noted that certain vitamins and drugs can also interfere with readings.
Bao doesn’t see value in having people without diabetes monitor their glucose continuously. “If they want to see what foods or exercise do to their body, they will probably benefit from a short trial to gain some insight; otherwise, they’re wasting money,” she said.
Another potential downside is that there’s no head-to-head comparison data with the approved devices, Garg said. “But it’s clear to us that Stelo’s range is very narrow, 70 to 200, whereas the Lingo ranges are pretty much full, from 40 to 400 or 55 to 400. So, we don’t know the accuracy of these sensors.”
Golden observed that for certain patients, CGMs may lead to psychological distress rather than providing a sense of control over their blood glucose levels.
“I have had a nondiabetic patient or two that obsessed about their blood sugars and a device would only magnify their anxiety/neurosis,” he said. “The bottom line is that it’s a tool for a balanced approach to health management, but the daily results must be kept in perspective!”
Educate Patients, Primary Care Physicians
To maximize potential benefits for patients without diabetes, clinicians need to be well trained in the use and interpretation of results from the devices, Bao said. They can then better educate their patients, including discussing with them possible pitfalls surrounding their use.
“For example, a patient may see that their blood glucose, as measured by a fingerstick, is 95, whereas the CGM says 140, and ask, ‘Which one do I trust?’ ”
This is where the patient can be educated about the difference between interstitial glucose, as measured by the CGM, and blood glucose, as measured by the fingerstick. Because it takes about 15 minutes for blood glucose to get to the interstitial tissue, there’s lag time, and the two measurements will differ.
“A discrepancy of 20% is totally acceptable for that reason,” Bao said.
She has also seen several examples where patients were misled by their CGM when its censor became dislodged.
“Sometimes when a sensor has moved, the patient may push it back in because they don’t want to throw it away. But it doesn’t work that way, and they end up with inaccurate readings.”
At a minimum, Bao added, clinicians and patients should read the package insert but also be aware that it doesn’t list everything that might go wrong or interfere with the device’s accuracy.
Manufacturers of OTC devices should be training primary care and family practice doctors in their use, given the expected “huge” influx of patients wanting to use them, according to Garg.
“If you are expecting endos or diabetes specialists to see these people, that’s never going to happen,” he said. “We have a big shortage of these specialists, so industry has to train these doctors. Patients will bring their doctor’s data, and the clinicians need to learn the basics of how to interpret the glucose values they see. Then they can treat these patients rather than shipping all of them to endos who likely are not available.”
Paauw agreed that CGM training should be directed largely toward primary care professionals, who can help their under-resourced endocrinologist colleagues from seeing an uptick in “the worried well.”
“The bottom line is that primary care professionals do need to understand the CGM,” he said. “They do need to get comfortable with it. They do need to come up with opinions on how to use it. The public’s going to be using it, and we need to be competent in it and use our subspecialists appropriately.”

Doctors Caution Over Weight Loss Drug Link to Nurse’s Death
Doctors have urged caution in linking the weight loss drug tirzepatide to the death of a 58-year-old nurse from Scotland.
Susan McGowan, from North Lanarkshire, took two low-dose injections of tirzepatide (Mounjaro) over the course of about 2 weeks before her death in September.
BBC News reported that multiple organ failure, septic shock, and pancreatitis were listed on her death certificate as the immediate cause of death, with “the use of prescribed tirzepatide” recorded as a contributing factor.
McGowan worked as a nurse at University Hospital Monklands in Airdrie. A family member said that, apart from carrying a “bit of extra weight,” she had been otherwise healthy and was not taking any other medication.
It is understood that McGowan had sought medical advice before purchasing a prescription for tirzepatide through a registered UK pharmacy. However, days after administering a second injection, she went to A&E at Monklands with severe stomach pain and sickness. She died on September 4.
Expert Insights
Commenting to the Science Media Centre (SMC), Amanda Adler, MD, PhD, professor of diabetic medicine and health policy at the University of Oxford, described the nurse’s death as “sad” but said that “whether or not it was related to tirzepatide may be difficult to prove.” While tirzepatide can be associated with uncommon problems such as acute pancreatitis, “one can develop acute pancreatitis for many other reasons as well,” she said.
Naveed Sattar, MD, PhD, professor of metabolic medicine at the University of Glasgow, noted that data from multiple trials of tirzepatide, involving around 10,000 people living with diabetes or obesity, “do not suggest a higher risk of pancreatitis.” Furthermore, “the data seem to show acceptable safety thus far and a range of benefits including sizable average weight loss (near 20%), strong diabetes prevention, and considerable benefits in people living with sleep apnea,” he told the SMC.
Approved Based on Extensive Assessment
Tirzepatide, a GLP-1 receptor agonist, was approved for use as a weight loss aid in the United Kingdom in November last year by the Medicines and Healthcare products Regulatory Agency (MHRA). It lists nausea, diarrhea, and vomiting as the most common side effects, as well as hypoglycemia for patients with diabetes.
Available figures under the Yellow Card scheme up to 19 May 2024 show that there were 208 adverse drug reactions reported about tirzepatide this year, including 31 serious reactions and one suspected death of a man in his 60s.
In a statement, a spokesperson for the drug’s manufacturer, Eli Lilly, said, “Patient safety is Lilly’s top priority. We are committed to continually monitoring, evaluating, and reporting safety information for all Lilly medicines.
“Mounjaro (tirzepatide) was approved based on extensive assessment of the benefits and risks of the medicine, and we provide information about the benefits and risks of all our medicines to regulators around the world to ensure the latest information is available for prescribers. If anyone is experiencing side effects when taking any Lilly medicine, they should talk to their doctor or other healthcare professional.”
In October, the NHS submitted plans to the National Institute for Health and Care Excellence (NICE) for a phased rollout of tirzepatide in England that would initially prioritize patients with the greatest clinical need. The first phase would see the drug available to people with a body mass index of more than 40 kg/m2 who also suffer from at least three of the main weight-related health problems: hypertension, dyslipidemia, obstructive sleep apnea, and cardiovascular disease.
“Our sincere sympathies are with the family of individual concerned,” said Alison Cave, MHRA Chief Safety Officer.
“Patient safety is our top priority and no medicine would be approved unless it met our expected standards of safety, quality, and effectiveness. Our role is to continually monitor the safety of medicines during their use, such as GLP-1 RAs. We have robust, safety monitoring and surveillance systems in place for all healthcare products.
“New medicines, such as tirzepatide, are more intensively monitored to ensure that any new safety issues are identified promptly. We strongly encourage the reporting of all suspected reactions to newer medicines, which are denoted by an inverted Black Triangle symbol.
“On the basis of the current evidence the benefits of GLP-1 RAs outweigh the potential risks when used for the licensed indications. The decision to start, continue, or stop treatments should be made jointly by patients and their doctor, based on full consideration of the benefits and risks.”
She encouraged patients and healthcare professionals to continue reporting suspected side effects to GLP-1 RAs, such as tirzepatide, through the Yellow Card Scheme. “When a safety issue is confirmed, we always act promptly to inform patients and healthcare professionals and take appropriate steps to mitigate any identified risk.”
The Department of Health and Social Care declined to comment.
Adler disclosed being involved as an unpaid investigator on an Eli Lilly–funded trial for a different drug. Sattar has disclosed no relevant financial relationships.

‘Round Face’: A Viral Term’s Real Diagnostic Implications
“Cortisol” has become a household word, popularized by social media and tagged in videos that garnered nearly 800 million views in 2023. This is linked to the also-trending term “moon face,” which TikTok influencers and others have suggested is caused by high cortisol levels and, conversely, can be reduced through stress reduction.
“When we hear the term ‘moon face,’ we’re typically referring to Cushing syndrome [CS] or treatment with prolonged high-dose glucocorticoids,” said Anat Ben-Shlomo, MD, co-director of the Multidisciplinary Adrenal Program, Pituitary Center, Division of Endocrinology, Diabetes and Metabolism at Cedars-Sinai Medical Center, Los Angeles. Medscape Medical News previously discussed moon face in an article detailing how to diagnose CS.
Ben-Shlomo noted that the labels “moon face” and “moon facies” should be avoided for their potentially derogatory, unprofessional-sounding connotations, and that the preferred terms are “rounded face” or “round plethoric face.”
There are several disorders that can be associated with facial roundness, not all of which relate to elevated cortisol.
“It’s important for clinicians to be able distinguish between presentations due to other pathophysiologies, identify the unique constellation of Cushing-associated signs and symptoms, engage in a differential diagnosis, and treat whatever the condition is appropriately,” Katherine Sherif, MD, professor and vice chair of academic affairs, Department of Medicine, Thomas Jefferson University, Philadelphia, said in an interview.
The Unique Presentation of CS
CS results from “prolonged elevation” in plasma cortisol levels caused by either exogenous steroid use or excess endogenous steroid production.
“The shape of the face isn’t the only feature associated with CS,” Ben-Shlomo said. “There’s central obesity, particularly in the neck, supraclavicular area, chest, and abdomen. You sometimes see a posterior cervical thoracic fat pad, colloquially — but unprofessionally — called a ‘cervical hump.’ Simultaneously, the arms and legs are getting thinner.” The development of a round, plethoric face is common in long-standing significant CS, and a reddening of the skin can appear.
Additional symptoms include hirsutism and acne. “These can also be seen in other conditions, such as PCOS [polycystic ovary syndrome] but, combined with the other facial features, are more suggestive of CS,” Ben-Shlomo said.
Deep, wide purple striae appear in the trunk, breast, upper arms, and thighs, but not in the face, Ben-Shlomo advised. These appear as the fragile, thinning under-skin breaks when the patient gains weight.
Additional metabolic issues that can occur comorbidly include insulin resistance and diabetes, hypertension, osteoporosis, dyslipidemia, ecchymoses, increased susceptibility to infections, mood changes, cognitive dysfunction, low libido, infertility, weakness of muscles in the shoulders and thighs, episodes of bleeding and/or clotting, and an increased risk for heart attacks and strokes, Ben-Shlomo said.
“Not everyone presents with full-blown disease, but if you see any of these symptoms, be suspicious of CS and conduct a biochemical evaluation.” Three screening tests to use as a starting point are recommended by the Pituitary Society’s updated Consensus on Diagnosis and Management of Cushing’s Disease. The tests should be repeated to account for intra-patient variability. If two or all three tests are positive, clinicians should be suspicious of CS and move to additional testing to identify the underlying cause, Ben-Shlomo said.
‘Subclinical’ CS
Ben-Shlomo highlighted a condition called minimal autonomous cortisol secretion (formerly “subclinical CS”). “This condition is found when a person has an adrenal nodule that produces cortisol in excess, however not to levels observed in CS. An abnormal finding on the overnight 1-mg low-dose dexamethasone suppression test (LDDST) will identify this disorder, showing mildly unsuppressed morning cortisol level, while all other tests will be within normal range.”
She described minimal autonomous cortisol secretion as a form of “smoldering CS,” which has become more commonly diagnosed. “The condition needs to be treated because the patient can develop insulin resistance, metabolic syndrome, and osteoporosis over time.”
Once a cause has been determined, the optimal course of action is to take a multidisciplinary approach because CS affects multiple systems.
‘Pseudo-Cushing Syndrome’
A variety of abnormalities of the hypothalamus-pituitary adrenal (HPA) axis can be associated with hypercortisolemia and a rounder facial appearance but aren’t actually CS, Ben-Shlomo said.
Often called “pseudo-Cushing syndrome,” these conditions have recently been renamed “non-neoplastic hypercortisolism” or “physiologic non-neoplastic endogenous hypercortisolism.” They share some clinical and biochemical features of CS, but the hypercortisolemia is usually secondary to other factors. They increase the secretion of hypothalamic corticotropin-releasing hormone, which stimulates adrenocorticotropic hormone (ACTH) and adrenal cortisol secretion.
Identifying PCOS
PCOS is often associated with central obesity, Sherif noted, but not all women with PCOS have overweight or a central distribution of fat.
“Ask about menstrual periods and whether they come monthly,” Sherif advised. “If women using hormonal contraception say they have a regular cycle, ask if their cycle was regular prior to starting contraception. So many women with PCOS are undiagnosed because they started contraception in their teens to ‘regulate their periods’ and never realized they had PCOS.”
Additional symptoms of PCOS and its impact are found in the figure below.
PCOS is diagnosed when two of the following three Rotterdam criteria are met, and other diagnoses are excluded:
- Irregular menstrual cycles
- Clinical hyperandrogenism or biochemical hyperandrogenism
- Polycystic ovarian morphology on transvaginal ultrasonography or high anti-mullerian hormone (applicable only if patient is ≥ 8 years from menarche)
If PCOS is suspected, further tests can be conducted to confirm or rule out the diagnosis.
Alcohol Abuse: Alcohol abuse stimulates hypothalamic corticotropin-releasing hormone, leading to increased ACTH levels. It’s associated with a higher fasting cortisol level, particularly at 8:30 AM or so, and attributable to impaired cortisol clearance due to alcohol-related hepatic dysfunction. The LDDST will show abnormal cortisol suppression.
Sherif advised asking patients about alcohol use, recommending treatment for alcohol use disorder, and repeating clinical and biochemical workup after patients have discontinued alcohol consumption for ≥ 1 month.
Eating Disorders Mimicking CS: Eating disorders, particularly anorexia nervosa, are associated with endocrine abnormalities, amenorrhea, impaired body temperature regulation, and hypercortisolism, likely due to chronic fasting-related stress. Dysregulation of the HPA axis may linger, even after weight recovery.
It’s unlikely that patients with anorexia will display the “rounded face” associated with hypercortisolism, but some research suggests that anorexia can result in a disproportionate accumulation of central adiposity after recovery from the illness.
Neuropsychiatric Disorders: Major depressive disorder (MDD) is associated with HPA axis hyperactivity, with 20%-30% of patients with MDD showing hypercortisolemia. The post-awakening cortisol surge is more pronounced in those with MDD, and about half of patients with MDD also have high evening cortisol levels, suggesting disrupted diurnal cortisol rhythms.
Some patients with MDD have greater resistance to the feedback action of glucocorticoids on HPA axis activity, with weaker sensitivity often restored by effective pharmacotherapy of the depressive condition. Neuropsychiatric disorders are also associated with reduced activity of cortisol-deactivating enzymes. Posttraumatic stress disorder and anxiety are similarly associated with hypercortisolemia.
Addressing neuropsychiatric conditions with appropriate pharmacotherapy and psychotherapy can restore cortisol levels to normal proportions.
Diabetes, Obesity, and Metabolic Syndrome: Diabetes, obesity, and metabolic syndrome can occur comorbidly with CS, and many patients with these conditions may display both a rounder face, some central adiposity, and hypercortisolemia. For example, obesity is often related to a hyperresponsive HPA axis, with elevated cortisol secretion but normal-to-low circulatory concentrations.
Obesity is associated with increased cortisol reactivity after acute physical and/or psychosocial stressors but preserved pituitary sensitivity to feedback inhibition by the LDDST. When these conditions are appropriately managed with pharmacotherapy and lifestyle changes, cortisol levels should normalize, according to the experts.
Hypothyroidism: Hypothyroidism— Hashimoto disease as well as the subclinical variety — can be associated with weight gain, which may take the form of central obesity. Some research suggests a bidirectional relationship between hypothyroidism and obesity.
“Years ago, we didn’t conduct thyroid tests very often but now they’re easy to do, so we usually catch people with hypothyroidism at the beginning of the condition,” Sherif said. “If the patient’s thyroid hasn’t been checked in a year or so, thyroid hormone testing should be conducted.”
Thyroid disease can easily be managed with the administration of thyroid hormones.
Obstructive Sleep Apnea (OSA): OSA has an impact on HPA axis activation, especially when accompanied by obesity and hypertension. A meta-analysis of 22 studies, encompassing over 600 participants, found that continuous positive airway pressure treatment in patients with OSA reduced cortisol levels as well as blood pressure.
Treatment With Exogenous Corticosteroids: Oral corticosteroid treatment is a cornerstone of therapy in transplant, rheumatic, and autoimmune diseases. The impact of chronic exposure to exogenous glucocorticoids is similar to that with endogenous glucocorticoids.
Sherif said corticosteroid treatment can cause facial roundness in as little as 2 weeks and is characteristic in people taking these agents for longer periods. Although the effects are most pronounced with oral agents, systemic effects can be associated with inhaled corticosteroids as well.
Finding alternative anti-inflammatory treatments is advisable, if possible. The co-administration of metformin might lead to improvements in both the metabolic profile and the clinical outcomes of patients receiving glucocorticoids for inflammatory conditions.
Educating Patients: “There’s much we still don’t know about hypercortisolemia and CS, including the reasons for its impact on metabolic derangement and for the accumulation of fat in particular adipose patterns,” Ben-Shlomo said. “But experienced endocrinologists do know relatively well how to diagnose the condition, distinguish it from other conditions presenting with central obesity or a rounder face, and treat it.”
Given the casual use of the terms “moon face” and “extra cortisol” on social media, it’s important for physicians to educate patients about what elevated cortisol does and doesn’t do, and design treatment strategies accordingly.

“Cortisol” has become a household word, popularized by social media and tagged in videos that garnered nearly 800 million views in 2023. This is linked to the also-trending term “moon face,” which TikTok influencers and others have suggested is caused by high cortisol levels and, conversely, can be reduced through stress reduction.
“When we hear the term ‘moon face,’ we’re typically referring to Cushing syndrome [CS] or treatment with prolonged high-dose glucocorticoids,” said Anat Ben-Shlomo, MD, co-director of the Multidisciplinary Adrenal Program, Pituitary Center, Division of Endocrinology, Diabetes and Metabolism at Cedars-Sinai Medical Center, Los Angeles. Medscape Medical News previously discussed moon face in an article detailing how to diagnose CS.
Ben-Shlomo noted that the labels “moon face” and “moon facies” should be avoided for their potentially derogatory, unprofessional-sounding connotations, and that the preferred terms are “rounded face” or “round plethoric face.”
There are several disorders that can be associated with facial roundness, not all of which relate to elevated cortisol.
“It’s important for clinicians to be able distinguish between presentations due to other pathophysiologies, identify the unique constellation of Cushing-associated signs and symptoms, engage in a differential diagnosis, and treat whatever the condition is appropriately,” Katherine Sherif, MD, professor and vice chair of academic affairs, Department of Medicine, Thomas Jefferson University, Philadelphia, said in an interview.
The Unique Presentation of CS
CS results from “prolonged elevation” in plasma cortisol levels caused by either exogenous steroid use or excess endogenous steroid production.
“The shape of the face isn’t the only feature associated with CS,” Ben-Shlomo said. “There’s central obesity, particularly in the neck, supraclavicular area, chest, and abdomen. You sometimes see a posterior cervical thoracic fat pad, colloquially — but unprofessionally — called a ‘cervical hump.’ Simultaneously, the arms and legs are getting thinner.” The development of a round, plethoric face is common in long-standing significant CS, and a reddening of the skin can appear.
Additional symptoms include hirsutism and acne. “These can also be seen in other conditions, such as PCOS [polycystic ovary syndrome] but, combined with the other facial features, are more suggestive of CS,” Ben-Shlomo said.
Deep, wide purple striae appear in the trunk, breast, upper arms, and thighs, but not in the face, Ben-Shlomo advised. These appear as the fragile, thinning under-skin breaks when the patient gains weight.
Additional metabolic issues that can occur comorbidly include insulin resistance and diabetes, hypertension, osteoporosis, dyslipidemia, ecchymoses, increased susceptibility to infections, mood changes, cognitive dysfunction, low libido, infertility, weakness of muscles in the shoulders and thighs, episodes of bleeding and/or clotting, and an increased risk for heart attacks and strokes, Ben-Shlomo said.
“Not everyone presents with full-blown disease, but if you see any of these symptoms, be suspicious of CS and conduct a biochemical evaluation.” Three screening tests to use as a starting point are recommended by the Pituitary Society’s updated Consensus on Diagnosis and Management of Cushing’s Disease. The tests should be repeated to account for intra-patient variability. If two or all three tests are positive, clinicians should be suspicious of CS and move to additional testing to identify the underlying cause, Ben-Shlomo said.
‘Subclinical’ CS
Ben-Shlomo highlighted a condition called minimal autonomous cortisol secretion (formerly “subclinical CS”). “This condition is found when a person has an adrenal nodule that produces cortisol in excess, however not to levels observed in CS. An abnormal finding on the overnight 1-mg low-dose dexamethasone suppression test (LDDST) will identify this disorder, showing mildly unsuppressed morning cortisol level, while all other tests will be within normal range.”
She described minimal autonomous cortisol secretion as a form of “smoldering CS,” which has become more commonly diagnosed. “The condition needs to be treated because the patient can develop insulin resistance, metabolic syndrome, and osteoporosis over time.”
Once a cause has been determined, the optimal course of action is to take a multidisciplinary approach because CS affects multiple systems.
‘Pseudo-Cushing Syndrome’
A variety of abnormalities of the hypothalamus-pituitary adrenal (HPA) axis can be associated with hypercortisolemia and a rounder facial appearance but aren’t actually CS, Ben-Shlomo said.
Often called “pseudo-Cushing syndrome,” these conditions have recently been renamed “non-neoplastic hypercortisolism” or “physiologic non-neoplastic endogenous hypercortisolism.” They share some clinical and biochemical features of CS, but the hypercortisolemia is usually secondary to other factors. They increase the secretion of hypothalamic corticotropin-releasing hormone, which stimulates adrenocorticotropic hormone (ACTH) and adrenal cortisol secretion.
Identifying PCOS
PCOS is often associated with central obesity, Sherif noted, but not all women with PCOS have overweight or a central distribution of fat.
“Ask about menstrual periods and whether they come monthly,” Sherif advised. “If women using hormonal contraception say they have a regular cycle, ask if their cycle was regular prior to starting contraception. So many women with PCOS are undiagnosed because they started contraception in their teens to ‘regulate their periods’ and never realized they had PCOS.”
Additional symptoms of PCOS and its impact are found in the figure below.
PCOS is diagnosed when two of the following three Rotterdam criteria are met, and other diagnoses are excluded:
- Irregular menstrual cycles
- Clinical hyperandrogenism or biochemical hyperandrogenism
- Polycystic ovarian morphology on transvaginal ultrasonography or high anti-mullerian hormone (applicable only if patient is ≥ 8 years from menarche)
If PCOS is suspected, further tests can be conducted to confirm or rule out the diagnosis.
Alcohol Abuse: Alcohol abuse stimulates hypothalamic corticotropin-releasing hormone, leading to increased ACTH levels. It’s associated with a higher fasting cortisol level, particularly at 8:30 AM or so, and attributable to impaired cortisol clearance due to alcohol-related hepatic dysfunction. The LDDST will show abnormal cortisol suppression.
Sherif advised asking patients about alcohol use, recommending treatment for alcohol use disorder, and repeating clinical and biochemical workup after patients have discontinued alcohol consumption for ≥ 1 month.
Eating Disorders Mimicking CS: Eating disorders, particularly anorexia nervosa, are associated with endocrine abnormalities, amenorrhea, impaired body temperature regulation, and hypercortisolism, likely due to chronic fasting-related stress. Dysregulation of the HPA axis may linger, even after weight recovery.
It’s unlikely that patients with anorexia will display the “rounded face” associated with hypercortisolism, but some research suggests that anorexia can result in a disproportionate accumulation of central adiposity after recovery from the illness.
Neuropsychiatric Disorders: Major depressive disorder (MDD) is associated with HPA axis hyperactivity, with 20%-30% of patients with MDD showing hypercortisolemia. The post-awakening cortisol surge is more pronounced in those with MDD, and about half of patients with MDD also have high evening cortisol levels, suggesting disrupted diurnal cortisol rhythms.
Some patients with MDD have greater resistance to the feedback action of glucocorticoids on HPA axis activity, with weaker sensitivity often restored by effective pharmacotherapy of the depressive condition. Neuropsychiatric disorders are also associated with reduced activity of cortisol-deactivating enzymes. Posttraumatic stress disorder and anxiety are similarly associated with hypercortisolemia.
Addressing neuropsychiatric conditions with appropriate pharmacotherapy and psychotherapy can restore cortisol levels to normal proportions.
Diabetes, Obesity, and Metabolic Syndrome: Diabetes, obesity, and metabolic syndrome can occur comorbidly with CS, and many patients with these conditions may display both a rounder face, some central adiposity, and hypercortisolemia. For example, obesity is often related to a hyperresponsive HPA axis, with elevated cortisol secretion but normal-to-low circulatory concentrations.
Obesity is associated with increased cortisol reactivity after acute physical and/or psychosocial stressors but preserved pituitary sensitivity to feedback inhibition by the LDDST. When these conditions are appropriately managed with pharmacotherapy and lifestyle changes, cortisol levels should normalize, according to the experts.
Hypothyroidism: Hypothyroidism— Hashimoto disease as well as the subclinical variety — can be associated with weight gain, which may take the form of central obesity. Some research suggests a bidirectional relationship between hypothyroidism and obesity.
“Years ago, we didn’t conduct thyroid tests very often but now they’re easy to do, so we usually catch people with hypothyroidism at the beginning of the condition,” Sherif said. “If the patient’s thyroid hasn’t been checked in a year or so, thyroid hormone testing should be conducted.”
Thyroid disease can easily be managed with the administration of thyroid hormones.
Obstructive Sleep Apnea (OSA): OSA has an impact on HPA axis activation, especially when accompanied by obesity and hypertension. A meta-analysis of 22 studies, encompassing over 600 participants, found that continuous positive airway pressure treatment in patients with OSA reduced cortisol levels as well as blood pressure.
Treatment With Exogenous Corticosteroids: Oral corticosteroid treatment is a cornerstone of therapy in transplant, rheumatic, and autoimmune diseases. The impact of chronic exposure to exogenous glucocorticoids is similar to that with endogenous glucocorticoids.
Sherif said corticosteroid treatment can cause facial roundness in as little as 2 weeks and is characteristic in people taking these agents for longer periods. Although the effects are most pronounced with oral agents, systemic effects can be associated with inhaled corticosteroids as well.
Finding alternative anti-inflammatory treatments is advisable, if possible. The co-administration of metformin might lead to improvements in both the metabolic profile and the clinical outcomes of patients receiving glucocorticoids for inflammatory conditions.
Educating Patients: “There’s much we still don’t know about hypercortisolemia and CS, including the reasons for its impact on metabolic derangement and for the accumulation of fat in particular adipose patterns,” Ben-Shlomo said. “But experienced endocrinologists do know relatively well how to diagnose the condition, distinguish it from other conditions presenting with central obesity or a rounder face, and treat it.”
Given the casual use of the terms “moon face” and “extra cortisol” on social media, it’s important for physicians to educate patients about what elevated cortisol does and doesn’t do, and design treatment strategies accordingly.

Update Coming for Thyroid Disease in Pregnancy Guidelines
CHICAGO — A preview of much-anticipated updates to guidelines on managing thyroid disease in pregnancy shows key changes to recommendations in the evolving field, ranging from consideration of the chance of spontaneous normalization of thyroid levels during pregnancy to a heightened emphasis on shared decision-making and the nuances can factor into personalized treatment.
The guidelines, expected to be published in early 2025, have not been updated since 2017, and with substantial advances and evidence from countless studies since then, the new guidelines were developed with a goal to start afresh, said ATA Thyroid and Pregnancy Guidelines Task Force cochair Tim IM Korevaar, MD, PhD, in presenting the final draft guidelines at the American Thyroid Association (ATA) 2024 Meeting.
“Obviously, we’re not going to ignore the 2017 guidelines, which have been a very good resource for us so far, but we really wanted to start from scratch and follow a ‘blank canvas’ approach in optimizing the evidence,” said Korevaar, an endocrinologist and obstetric internist with the Division of Pharmacology and Vascular Medicine & Academic Center for Thyroid Diseases, Department of Internal Medicine, Erasmus University Medical Center, Rotterdam, The Netherlands.
The guidelines, developed through a collaborative effort involving a wide variety of related medical societies, involved 14 systematic literature reviews. While the pregnancy issues covered by the guidelines is extensive, key highlights include:
Management in Preconception
Beginning with preconception, a key change in the guidelines will be that patients with euthyroid thyroid peroxidase (TPO) antibodies, which can be indicative of thyroid dysfunction, routine treatment with levothyroxine is not recommended, based on new evidence from randomized trials of high-risk patients showing no clear benefit from the treatment.
“In these trials, and across analyses, there was absolutely no beneficial effect of levothyroxine in these patients [with euthyroid TPO antibody positivity],” he said.
With evidence showing, however, that TPO antibody positivity can lead to subclinical or overt hypothyroidism within 1 or 2 years, the guidelines will recommend that TPO antibody–positive patients do have thyroid stimulating hormone (TSH) levels tested every 3-6 months until pregnancy, and existing recommendations to test during pregnancy among those patients remain in place, Korevaar reported.
In terms of preconception subclinical hypothyroidism, the guidelines will emphasize the existing recommendation “to always strive to reassess” thyroid levels, and if subclinical hypothyroidism does persist, to treat with low-dose levothyroxine.
During Pregnancy
During pregnancy, the new proposed recommendations will reflect the important change that three key risk factors, including age over 30 years, having at least two prior pregnancies, and morbid obesity (body mass index [BMI] at least 40 kg/m2), previously considered a risk for thyroid dysfunction in pregnancy, should not, on their own, suggest the need for thyroid testing, based on low evidence of an increased risk in pregnancy.
Research on the issue includes a recent study from Korevaar’s team showing these factors to in fact have low predictability of thyroid dysfunction.
“We deemed that these risk differences weren’t really clinically meaningful (in predicting risk), and so we have removed to maternal age, BMI, and parity as risk factors for thyroid testing indications in pregnancy,” Korevaar said.
Factors considered a risk, resulting in recommended testing at presentation include a history of subclinical or clinical hypo- or hyperthyroidism, postpartum thyroiditis, known thyroid antibody positivity, symptoms of thyroid dysfunction or goiter, and other factors.
Treatment for Subclinical Hypothyroidism in Pregnancy
Whereas current guidelines recommend TPO antibody status in determining when to consider treatment for subclinical hypothyroidism, the new proposed guideline will instead recommend treatment based on the timing of the diagnosis of the subclinical hypothyroidism, with consideration of treatment during the first trimester, but not in the second or third trimester, based on newer evidence of the absolute risk for pregnancy complications and randomized trial data.
“The recommendations are now to no longer based on TPO antibody status, but instead according to the timing of the diagnosis of subclinical hypothyroidism,” Korevaar said.
Based on the collective data, “due to the low risk, we do not recommend for routine levothyroxine treatment in the second or third trimester groups with TSH levels under 10 mU/L now.”
“However, for subclinical hypothyroidism diagnosed in the first trimester, the recommendation would be that you can consider levothyroxine treatment,” he said.
While a clear indication for treatment in any trimester is the presence of overt hypothyroidism, or TSH levels over 10 mU/L, Korevaar underscored the importance of considering nuances of the recommendations that may warrant flexibility, for instance among patients with borderline TSH levels.
Spontaneous Normalization of Thyroid Levels in Pregnancy
Another new recommendation addresses the issue of spontaneous normalization of abnormal thyroid function during pregnancy, with several large studies showing a large proportion of subclinical hypothyroidism cases spontaneously revert to euthyroidism by the third trimester — despite no treatment having been provided.
Under the important proposed recommendation, retesting of subclinical hypothyroidism is suggested within 3 weeks.
“The data shows that a large proportion of patients spontaneously revert to euthyroidism,” Korevaar said.
“Upon identifying subclinical hypothyroidism in the first trimester, there will be essentially two options that clinicians can discuss with their patient — one would be to consider confirmatory tests in 3 weeks or to discuss the starting the lower dose levothyroxine in the first trimester,” he said.
In terms of overt hypothyroidism, likewise, if patients have a TSH levels below 6 mU/L in pregnancy, “you can either consider doing confirmatory testing within 3 weeks, or discussing with the patient starting levothyroxine treatment,” Korevaar added.
Overt Hyperthyroidism
For overt hyperthyroidism, no significant changes from current guidelines are being proposed, with the key exception of a heightened emphasis on the need for shared decision-making with patients, Korevaar said.
“We want to emphasize shared decision-making especially for women who have Graves’ disease prior to pregnancy, because the antithyroid treatment modalities, primarily methimazole (MMI) and propylthiouracil (PTU), have different advantages and disadvantages for an upcoming pregnancy,” he said.
“If you help a patient become involved in the decision-making process, that can also be very helpful in managing the disease and following-up on the pregnancy.”
Under the recommendations, PTU remains the preferred drug in overt hyperthyroidism, due to a more favorable profile in terms of potential birth defects vs MMI, with research showing a higher absolute risk of 3% vs 5%.
The guidelines further suggest the option of stopping the antithyroid medications upon a positive pregnancy test, with the exception of high-risk patients.
Korevaar noted that, if the treatment is stopped early in pregnancy, relapse is not likely to occur until after approximately 3 months, or 12 weeks, at which time, the high-risk teratogenic period, which is between week 5 and week 15, will have passed.
Current guidelines regarding whether to stop treatment in higher-risk hyperthyroid patients are recommended to remain unchanged.
Thyroid Nodules and Cancer
Recommendations regarding thyroid nodules and cancer during pregnancy are also expected to remain largely similar to those in the 2017 guidelines, with the exception of an emphasis on simply considering how the patient would normally be managed outside of pregnancy.
For instance, regarding the question of whether treatment can be withheld for 9 months during pregnancy. “A lot of times, the answer is yes,” Korevaar said.
Other topics that will be largely unchanged include issues of universal screening, definitions of normal and abnormal TSH and free T4 reference ranges and isolated hypothyroxinemia.
Steps Forward in Improving Updates, Readability
In addition to recommendation updates, the new guidelines are being revised to better reflect more recent evidence-based developments and user-friendliness.
“We have now made the step to a more systematic and replicable methodology to ensure for easier updates with a shorter interval,” Korevaar told this news organization.
“Furthermore, since 2006, the ATA guideline documents have followed a question-and-answer format, lacked recommendation tables and had none or only a few graphic illustrations,” he added.
“We are now further developing the typical outline of the guidelines to improve the readability and dissemination of the guideline document.”
Korevaar’s disclosures include lectureship fees from IBSA, Merck, and Berlin Chemie.

Recommendations regarding thyroid nodules and cancer during pregnancy are also expected to remain largely similar to those in the 2017 guidelines, with the exception of an emphasis on simply considering how the patient would normally be managed outside of pregnancy.
For instance, regarding the question of whether treatment can be withheld for 9 months during pregnancy. “A lot of times, the answer is yes,” Korevaar said.
Other topics that will be largely unchanged include issues of universal screening, definitions of normal and abnormal TSH and free T4 reference ranges and isolated hypothyroxinemia.
Steps Forward in Improving Updates, Readability
In addition to recommendation updates, the new guidelines are being revised to better reflect more recent evidence-based developments and user-friendliness.
“We have now made the step to a more systematic and replicable methodology to ensure for easier updates with a shorter interval,” Korevaar told this news organization.
“Furthermore, since 2006, the ATA guideline documents have followed a question-and-answer format, lacked recommendation tables and had none or only a few graphic illustrations,” he added.
“We are now further developing the typical outline of the guidelines to improve the readability and dissemination of the guideline document.”

CHICAGO — A preview of much-anticipated updates to guidelines on managing thyroid disease in pregnancy shows key changes to recommendations in the evolving field, ranging from consideration of the chance of spontaneous normalization of thyroid levels during pregnancy to a heightened emphasis on shared decision-making and the nuances can factor into personalized treatment.
The guidelines, expected to be published in early 2025, have not been updated since 2017, and with substantial advances and evidence from countless studies since then, the new guidelines were developed with a goal to start afresh, said ATA Thyroid and Pregnancy Guidelines Task Force cochair Tim IM Korevaar, MD, PhD, in presenting the final draft guidelines at the American Thyroid Association (ATA) 2024 Meeting.
“Obviously, we’re not going to ignore the 2017 guidelines, which have been a very good resource for us so far, but we really wanted to start from scratch and follow a ‘blank canvas’ approach in optimizing the evidence,” said Korevaar, an endocrinologist and obstetric internist with the Division of Pharmacology and Vascular Medicine & Academic Center for Thyroid Diseases, Department of Internal Medicine, Erasmus University Medical Center, Rotterdam, The Netherlands.
The guidelines, developed through a collaborative effort involving a wide variety of related medical societies, involved 14 systematic literature reviews. While the pregnancy issues covered by the guidelines is extensive, key highlights include:
Management in Preconception
Beginning with preconception, a key change in the guidelines will be that patients with euthyroid thyroid peroxidase (TPO) antibodies, which can be indicative of thyroid dysfunction, routine treatment with levothyroxine is not recommended, based on new evidence from randomized trials of high-risk patients showing no clear benefit from the treatment.
“In these trials, and across analyses, there was absolutely no beneficial effect of levothyroxine in these patients [with euthyroid TPO antibody positivity],” he said.
With evidence showing, however, that TPO antibody positivity can lead to subclinical or overt hypothyroidism within 1 or 2 years, the guidelines will recommend that TPO antibody–positive patients do have thyroid stimulating hormone (TSH) levels tested every 3-6 months until pregnancy, and existing recommendations to test during pregnancy among those patients remain in place, Korevaar reported.
In terms of preconception subclinical hypothyroidism, the guidelines will emphasize the existing recommendation “to always strive to reassess” thyroid levels, and if subclinical hypothyroidism does persist, to treat with low-dose levothyroxine.
During Pregnancy
During pregnancy, the new proposed recommendations will reflect the important change that three key risk factors, including age over 30 years, having at least two prior pregnancies, and morbid obesity (body mass index [BMI] at least 40 kg/m2), previously considered a risk for thyroid dysfunction in pregnancy, should not, on their own, suggest the need for thyroid testing, based on low evidence of an increased risk in pregnancy.
Research on the issue includes a recent study from Korevaar’s team showing these factors to in fact have low predictability of thyroid dysfunction.
“We deemed that these risk differences weren’t really clinically meaningful (in predicting risk), and so we have removed to maternal age, BMI, and parity as risk factors for thyroid testing indications in pregnancy,” Korevaar said.
Factors considered a risk, resulting in recommended testing at presentation include a history of subclinical or clinical hypo- or hyperthyroidism, postpartum thyroiditis, known thyroid antibody positivity, symptoms of thyroid dysfunction or goiter, and other factors.
Treatment for Subclinical Hypothyroidism in Pregnancy
Whereas current guidelines recommend TPO antibody status in determining when to consider treatment for subclinical hypothyroidism, the new proposed guideline will instead recommend treatment based on the timing of the diagnosis of the subclinical hypothyroidism, with consideration of treatment during the first trimester, but not in the second or third trimester, based on newer evidence of the absolute risk for pregnancy complications and randomized trial data.
“The recommendations are now to no longer based on TPO antibody status, but instead according to the timing of the diagnosis of subclinical hypothyroidism,” Korevaar said.
Based on the collective data, “due to the low risk, we do not recommend for routine levothyroxine treatment in the second or third trimester groups with TSH levels under 10 mU/L now.”
“However, for subclinical hypothyroidism diagnosed in the first trimester, the recommendation would be that you can consider levothyroxine treatment,” he said.
While a clear indication for treatment in any trimester is the presence of overt hypothyroidism, or TSH levels over 10 mU/L, Korevaar underscored the importance of considering nuances of the recommendations that may warrant flexibility, for instance among patients with borderline TSH levels.
Spontaneous Normalization of Thyroid Levels in Pregnancy
Another new recommendation addresses the issue of spontaneous normalization of abnormal thyroid function during pregnancy, with several large studies showing a large proportion of subclinical hypothyroidism cases spontaneously revert to euthyroidism by the third trimester — despite no treatment having been provided.
Under the important proposed recommendation, retesting of subclinical hypothyroidism is suggested within 3 weeks.
“The data shows that a large proportion of patients spontaneously revert to euthyroidism,” Korevaar said.
“Upon identifying subclinical hypothyroidism in the first trimester, there will be essentially two options that clinicians can discuss with their patient — one would be to consider confirmatory tests in 3 weeks or to discuss the starting the lower dose levothyroxine in the first trimester,” he said.
In terms of overt hypothyroidism, likewise, if patients have a TSH levels below 6 mU/L in pregnancy, “you can either consider doing confirmatory testing within 3 weeks, or discussing with the patient starting levothyroxine treatment,” Korevaar added.
Overt Hyperthyroidism
For overt hyperthyroidism, no significant changes from current guidelines are being proposed, with the key exception of a heightened emphasis on the need for shared decision-making with patients, Korevaar said.
“We want to emphasize shared decision-making especially for women who have Graves’ disease prior to pregnancy, because the antithyroid treatment modalities, primarily methimazole (MMI) and propylthiouracil (PTU), have different advantages and disadvantages for an upcoming pregnancy,” he said.
“If you help a patient become involved in the decision-making process, that can also be very helpful in managing the disease and following-up on the pregnancy.”
Under the recommendations, PTU remains the preferred drug in overt hyperthyroidism, due to a more favorable profile in terms of potential birth defects vs MMI, with research showing a higher absolute risk of 3% vs 5%.
The guidelines further suggest the option of stopping the antithyroid medications upon a positive pregnancy test, with the exception of high-risk patients.
Korevaar noted that, if the treatment is stopped early in pregnancy, relapse is not likely to occur until after approximately 3 months, or 12 weeks, at which time, the high-risk teratogenic period, which is between week 5 and week 15, will have passed.
Current guidelines regarding whether to stop treatment in higher-risk hyperthyroid patients are recommended to remain unchanged.
Thyroid Nodules and Cancer
Recommendations regarding thyroid nodules and cancer during pregnancy are also expected to remain largely similar to those in the 2017 guidelines, with the exception of an emphasis on simply considering how the patient would normally be managed outside of pregnancy.
For instance, regarding the question of whether treatment can be withheld for 9 months during pregnancy. “A lot of times, the answer is yes,” Korevaar said.

FROM ATA 2024
Are GLP-1s the Newest Fertility Treatment?
First, there were “Ozempic babies.” Now, there is also Ozempic-before-baby.
Unplanned pregnancies are still regularly being reported among people using glucagon-like peptide 1 receptor agonist (GLP-1 RA) drugs, and now fertility specialists are increasingly incorporating the medicines into preconception care plans.
The specialists say their colleagues in other areas of medicine may have an opportunity, too, to talk about weight loss using these new drugs in terms of reproductive health. Motivation and compliance can transform when the goal isn’t simply weight loss but having children.
“We have this really special moment to help patients be healthier, in order to be healthier for their kids,” said Christina Boots, MD, MSci, an associate professor of reproductive endocrinology and infertility at Northwestern University’s Feinberg School of Medicine, Chicago. “And I think that’s also a very motivating moment. It may be hard to get up and go for a run to make my jeans fit better, but when I think about it in terms of, ‘this might someday help my future daughter,’ that is a whole different level of motivation.”
Here’s why, what to know about the current lengthy list of unknowns and risks, and some options for approaching the topic with patients.
What Fertility Docs Are Doing
While overweight and obesity are consistently linked to fertility and pregnancy outcomes, Boots predicts the biggest impact of GLP-1 weight loss for fertility among women will be a specific subset: Those who are not cycling regularly, such as those with polycystic ovary syndrome (PCOS).
“The women who are cycling regularly who have very unexplained infertility and no other comorbidities like high blood pressure or something else going on, I don’t think it’s going to help their fertility very much at all,” she said “It might, but I think there’s probably something else going on in her tubes or with her eggs or his sperm, but it has nothing to do with her metabolic health.
Women who aren’t cycling regularly will benefit, but those with truly unexplained fertility probably won’t, she said.
In their recent narrative review on treating obesity and fertility with GLP-1 RAs that appeared in Fertility and Sterility, Boots and co-author Alyse S. Goldberg, MD, an endocrinologist with the University of Toronto, Ontario, Canada, advocate for the use of GLP-1s as a go-to treatment for obesity as part of preconception care by reproductive endocrinologists, calling the drugs “the most effective, least invasive means of weight loss.”
The paper is timely and necessary because use of GLP-1s is only going to increase, Patricia Jimenez, MD, an associate professor of obstetrics and gynecology at Washington University School of Medicine in St. Louis, Missouri, said in an email to this news organization.
“GLP-1 RAs are becoming a larger part of my practice. More patients are either using them already or interested in using them,” said Jimenez, who is board certified in reproductive endocrinology, obstetrics and gynecology, and obesity medicine. “I specifically see patients to discuss this and do prescribe antiobesity medications, not only GLP-1 RAs. Often this is with people with PCOS who are not planning to conceive soon or patients willing to delay fertility treatment [by] 3-6 months.”
Treating obesity is also important for women who are seeking in vitro fertilization, Boots said, because many IVF clinics have a body mass index cutoff of 40 kg/m2.
Like Jimenez’s approach, Boots and Goldberg call for comprehensive obesity care beyond the use of medication, including nutritional counseling and mental health support. Those supports are important during the transition off of GLP-1 medications, which poses a risk for rapid weight regain. That’s even with the potential support of taking metformin, which Boots often prescribes as a bridge.
Semaglutide should be stopped at least 2 months prior to conception, and tirzepatide should be stopped 1 month prior to conception, according to the manufacturers. (Boots and Goldberg listed the Canadian label recommendation for stopping tirzepatide, noting there is no suggested timeline for stopping prior to conception on the US label.)
Numerous studies have shown rapid weight regain is common when stopping GLP-1s, which presents a unique set of risks for pregnant women including early pregnancy loss, gestational diabetes, preeclampsia, and nonelective cesarean delivery.
Weighing Risks, Benefits, and Unknowns
Early looks at small human data sets, mostly involving semaglutide and earlier short-acting GLP-1s, and their impact on the risk for birth defects are “reassuring,” Boots said.
“But birth defects are just one small aspect. There’s also metabolic health and things like that long-term. Understanding what it does to the growing baby and the proximity of that medication to that growing baby is really important to see, and can’t be answered with animal studies, not perfectly anyway,” Boots said.
There are no published reports, from clinical trials nor case collections, examining the use of tirzepatide among pregnant people.
“One of the most important questions we need to answer is the preconception safety of these medications, and that includes safety for men,” Joshua Halpern, MD, MS, an adjunct assistant professor of urology at Northwestern University’s Feinberg School of Medicine, and chief scientific officer for Posterity Health, said in an email to this news organization.
“For example, a recent study found that men who were taking metformin, another popular medication for diabetes, were more likely to have children with birth defects, compared with those who were not taking the medication,” Halpern said. “Further studies are needed to determine whether a similar effect might hold true for the GLP-1 agonists.”
Small early studies on sperm are encouraging, Halpern said, suggesting that GLP-1 use may be beneficial, but a better understanding of direct effects is needed.
Among women, there may be cases where continuing use of a GLP-1 during pregnancy may offer benefits that outweigh risks, Boots suggested. Manufacturers have also created pregnancy exposure registries to measure the safety of their therapies during pregnancy.
“I have a group of patients whose sugars are so well controlled on these medications, but as soon as they come off, they get weight regain and their glucose is just so poorly controlled,” she said. “There may be a group of women where the benefits of glucose control outweigh the risks of being on the medication the whole pregnancy.”
The list of important unknowns also includes a need to examine how rapid weight loss may impact ovulation rates and spontaneous conception, as well as miscarriage rates, birth weight, and metabolic health of the child.
More detailed rebound weight gain data is coming next year, with additional analysis expected as well on birth weight and pregnancy outcomes, said Jacqueline Maya, MD, first author of the research abstract presented at this year’s American Diabetes Association conference that examined gestational weight gain among people with preexisting type 2 diabetes who were exposed to GLP-1s during pregnancy. The study included 47 exposed pregnancies (based on prescription records and electronic chart information) and compared gestational weight gain to 141 unexposed matched pregnancies. Among the exposed group, 62% exceeded recommended weight gain, compared with 41% in the unexposed group. On average, gestational weight gain in exposed pregnancies exceeded that among matched unexposed pregnancies by about 6 pounds.
The team is now working with an additional data set to examine exposed pregnancies among people with obesity, said Maya, an instructor of pediatrics at Mass General Hospital and Harvard School of Medicine. She is particularly interested in examining weight trajectories during pregnancy to see how they may affect fetal outcomes. Her team’s current project also will likely include analysis to examine other variables like postpartum weight gain and adiposity characteristics of the baby.
Maya said the team hopes to have more to report at the American Diabetes Association conference in June next year.
Offer the Conversation
Using a GLP-1 for weight loss takes time, usually around 1 year to reach a plateau. Boots encouraged nonfertility providers to ask patients of reproductive age about their family plans as an opening.
“I hope for all primary care doctors and gynecologists, that with any patient of reproductive age, you should be bringing this up, asking, ‘Have you thought about having kids? Are you thinking about it soon?’ And if they say they are sometime in the near future, then you can say, ‘Is it OK if I bring up your weight?’ And you should ask permission.”
If the patient declines, it’s OK to bring it up again at a future visit.
“People with obesity have often experienced negative weight bias that impacts their care,” Jimenez said. “Treat obesity as a disease, not a personal failing. Ask permission to discuss weight with the patient beforehand. If they say no, respect that answer. This goes a long way in developing a positive relationship, so they return for care and may be willing to discuss later.”
When patients are open to the conversation, Boots suggests not focusing on the potential for poor outcomes, and instead perhaps saying, “If you’re thinking about having a baby in 5 years, optimizing your health now will not only make your pregnancy healthier, but your child healthier long-term.”
Discussing contraception plans remains important. People starting semaglutide or tirzepatide should use contraception other than oral birth control for 4 weeks while starting the medicine and for 4 weeks after each dose increase.
Boots said that the contraception conversation is particularly important because many people have come to deeply believe that they are infertile and, thus, may perhaps think contraception advice doesn’t apply to them. Maya hypothesized that behavioral changes following weight loss may also be a pathway toward pregnancy.
“Pregnancy while on GLP-1 RAs does happen. I always have a discussion about this possibility and contraception. This can sometimes be challenging for people with infertility to consider,” Jimenez said. “Explaining the risks, benefits, and unknowns can help. As the [Fertility and Sterility] paper describes, the limited data available has not shown increased fetal or maternal complications. We need more high quality data to better understand the impact of exposure or use around the time of conception and during pregnancy.”
It’s also important to introduce the idea to patients that they may someday need to come off the medications, such as when they are ready to have children, and how important lifestyle and behavioral changes will be at that time, Maya said.
“We do know what the alternative is, and we do know what the risks of obesity are,” she said. “So, it’s a tug and pull. We’re not starting off with healthy. We’re starting off with a disease that is physically and emotionally very difficult for the patient, especially when it starts in childhood.”

“I have a group of patients whose sugars are so well controlled on these medications, but as soon as they come off, they get weight regain and their glucose is just so poorly controlled,” she said. “There may be a group of women where the benefits of glucose control outweigh the risks of being on the medication the whole pregnancy.”
The list of important unknowns also includes a need to examine how rapid weight loss may impact ovulation rates and spontaneous conception, as well as miscarriage rates, birth weight, and metabolic health of the child.
More detailed rebound weight gain data is coming next year, with additional analysis expected as well on birth weight and pregnancy outcomes, said Jacqueline Maya, MD, first author of the research abstract presented at this year’s American Diabetes Association conference that examined gestational weight gain among people with preexisting type 2 diabetes who were exposed to GLP-1s during pregnancy. The study included 47 exposed pregnancies (based on prescription records and electronic chart information) and compared gestational weight gain to 141 unexposed matched pregnancies. Among the exposed group, 62% exceeded recommended weight gain, compared with 41% in the unexposed group. On average, gestational weight gain in exposed pregnancies exceeded that among matched unexposed pregnancies by about 6 pounds.
The team is now working with an additional data set to examine exposed pregnancies among people with obesity, said Maya, an instructor of pediatrics at Mass General Hospital and Harvard School of Medicine. She is particularly interested in examining weight trajectories during pregnancy to see how they may affect fetal outcomes. Her team’s current project also will likely include analysis to examine other variables like postpartum weight gain and adiposity characteristics of the baby.
Maya said the team hopes to have more to report at the American Diabetes Association conference in June next year.
Offer the Conversation
Using a GLP-1 for weight loss takes time, usually around 1 year to reach a plateau. Boots encouraged nonfertility providers to ask patients of reproductive age about their family plans as an opening.
“I hope for all primary care doctors and gynecologists, that with any patient of reproductive age, you should be bringing this up, asking, ‘Have you thought about having kids? Are you thinking about it soon?’ And if they say they are sometime in the near future, then you can say, ‘Is it OK if I bring up your weight?’ And you should ask permission.”
If the patient declines, it’s OK to bring it up again at a future visit.
“People with obesity have often experienced negative weight bias that impacts their care,” Jimenez said. “Treat obesity as a disease, not a personal failing. Ask permission to discuss weight with the patient beforehand. If they say no, respect that answer. This goes a long way in developing a positive relationship, so they return for care and may be willing to discuss later.”
When patients are open to the conversation, Boots suggests not focusing on the potential for poor outcomes, and instead perhaps saying, “If you’re thinking about having a baby in 5 years, optimizing your health now will not only make your pregnancy healthier, but your child healthier long-term.”
Discussing contraception plans remains important. People starting semaglutide or tirzepatide should use contraception other than oral birth control for 4 weeks while starting the medicine and for 4 weeks after each dose increase.
Boots said that the contraception conversation is particularly important because many people have come to deeply believe that they are infertile and, thus, may perhaps think contraception advice doesn’t apply to them. Maya hypothesized that behavioral changes following weight loss may also be a pathway toward pregnancy.
“Pregnancy while on GLP-1 RAs does happen. I always have a discussion about this possibility and contraception. This can sometimes be challenging for people with infertility to consider,” Jimenez said. “Explaining the risks, benefits, and unknowns can help. As the [Fertility and Sterility] paper describes, the limited data available has not shown increased fetal or maternal complications. We need more high quality data to better understand the impact of exposure or use around the time of conception and during pregnancy.”
It’s also important to introduce the idea to patients that they may someday need to come off the medications, such as when they are ready to have children, and how important lifestyle and behavioral changes will be at that time, Maya said.
“We do know what the alternative is, and we do know what the risks of obesity are,” she said. “So, it’s a tug and pull. We’re not starting off with healthy. We’re starting off with a disease that is physically and emotionally very difficult for the patient, especially when it starts in childhood.”

Do Patients on Anti-Obesity Drugs Decrease Alcohol Use?
SAN ANTONIO —
The findings, from surveys of more than 14,000 participants in WeightWatchers’ telehealth weight management program, were presented on November 6 at the Obesity Society’s Obesity Week 2024 meeting by the company’s Chief Nutrition Officer, Michelle I. Cardel, PhD, RD, based in Gainesville, Florida.
Similar reductions in alcohol consumption were seen in people taking different classes of AOMs, suggesting “an additional mechanism by which AOMs reduce energy intake, and also signal a potential role for these medications to reduce alcohol use,” Cardel said, adding “Clinicians treating individuals for obesity may consider anti-obesity medications particularly among those who report higher alcohol intake.”
Asked to comment, session moderator and obesity researcher Joseph A. Skelton, MD, professor of pediatrics at Wake Forest University School of Medicine, Winston-Salem, North Carolina, said, “I think there are some overlapping pathways there, possibly a reward system or something like that in the brain. I don’t think we know exactly what the end result will be as a potential use of the medications. But there’s a signal that needs to be investigated more.”
Cardel noted that there was one previous large cohort study finding that semaglutide was associated with a lower risk for alcohol use disorder, and another study that analyzed social media threads of people saying they’d quit drinking after starting a GLP-1 drug. But this new study is the first to examine the relationship with different classes of AOMs and to quantify the amount of alcohol consumed.
About Half Reported Reduced Alcohol Consumption, Regardless the AOM Class
The study included 14,053 WeightWatchers’ telehealth program participants who initiated an AOM between January 2022 and August 2023 and refilled the same AOM between October and November 2023. Those who had previously used AOMs before coming to the program or who had undergone bariatric surgery were excluded.
Participants had a mean age of 43 years, were 86% women, were 60% White, and had a mean body mass index of 36. They were surveyed about their weekly alcohol use prior to AOM initiation and again at the time of AOM refill.
At baseline, they were divided into categories of 0 (no alcohol use; n = 6562), category 1 (one to three drinks for women and one to six for men; n = 5948), category 2 (4-6 for women and 7-14 for men; n = 1216), and category 3 (≥ 7 for women and ≥ 15 for men; n = 327).
At the second survey, 24% reported decreased drinking after starting an AOM, 71% reported no change, and 4% reported increased drinking (P < .0001). But when just the 7491 individuals who reported any alcohol use at baseline were included, 45% reported decreased drinking after starting an AOM, 52% reported no change, and only 2% reported increased drinking.
The decrease in drinking with AOM use rose with greater alcohol use at baseline, from 37% for category 1, 76% for category 2, and 91% for category 3. The proportions reporting increased drinking were just 3%, 1%, and 0%, respectively. The adjusted odds ratios (ORs) for decreasing drinking were 5.97 for category 2 (P < .0001) and 19.18 for category 3 (P < .0001) vs category 1.
The proportions reporting reduced drinking were similar across AOM classes: 51% for metformin, 46% for bupropion/naltrexone, 46% for first-generation GLP-1s (Saxenda, Trulicity, and Victoza), and 45% for the second-generation GLP-1 drugs (Mounjaro, Ozempic, Rybelsus, Wegovy, and Zepbound). All were statistically significant at P < .0001.
The highest proportion reporting increased drinking was 4% for bupropion/naltrexone. Compared with women, men were significantly more likely to report decreased drinking with AOM use (adjusted OR, 0.74; P < .001), but there were no differences by race/ethnicity or age.
Compared with those who had overweight, those in obesity classes I, II, and III were all more likely to decrease drinking with AOM use, with adjusted ORs of 1.26 (P = .0045), 1.49 (P < .001), and 1.63 (P < .001), respectively.
Mechanisms Appear Both Biological and Behavioral
During the discussion, Cardel said that qualitative assessments with participants suggest that there are at least two mechanisms behind this phenomenon: One biological and the other intentional.
“What we hear from them is twofold, one, particularly amongst those folks on GLP-1 medications, we’re hearing that physiologically, they feel different with the medications, that their cravings for alcohol are decreased, and that when they do choose to drink that there’s often a very much a negative reinforcement ... I’ve had a patient tell me, ‘I used to be able to have two or three margaritas, and maybe I didn’t feel like the best I’d ever felt in the morning, but I was okay. And now if I have two or three drinks, I will be throwing up for 5 hours, and it’s the worst hangover I’ve ever had in my life.’ And so it very much creates that negative reinforcement loop.”
But at the same time, “folks who are coming to us and seeking these medications are very much on a on a health-based journey. That’s what they tell us. The majority of our patients are there to improve their health. We rarely hear about the vanity or aesthetic part of it. So perhaps it’s that, in terms of trying to improve their health, they’re also trying to reduce their alcohol consumption, either just for their overall health or also as a means of trying to decrease their overall calorie consumption.”
In future research, Cardel said, “we want to examine whether the anti-obesity medications are more successful at reducing alcohol use compared to non-pharmacological weight management interventions, as we know that people often reduce their alcohol consumption on a weight management journey as a means of prioritizing their calories for food and decreasing the calories from alcohol.”
Cardel and all the study coauthors were employees and shareholders at WeightWatchers at the time the research was conducted. Skelton is editor in chief of the journal Childhood Obesity.

FROM OBESITY WEEK 2024
Liquid Fasting Mitigates Negative Pre-Surgery Impact of Semaglutide
These findings suggest that patients taking GLP-1 receptor agonists (GLP-1RAs) may benefit from a 24-hour liquid fast before anesthetic procedures without the need for a medication hold, reported lead author Haarika Korlipara, MD, of NewYork–Presbyterian/Weill Cornell Medical Center, New York, and colleagues.
“[T]he effects of delayed gastric emptying in patients on long-acting GLP-1RAs are clinically important in the management of anesthetized patients, who may develop periprocedural complications in the setting of retained solid gastric contents,” the investigators wrote in Techniques and Innovations in Gastrointestinal Endoscopy.
The researchers retrospectively analyzed clinical data from 1,212 patients undergoing upper endoscopy at a tertiary care center. Among them, 602 were on semaglutide for more than four weeks, while 610 were controls not taking the medication.
The primary outcome was the presence of retained solid gastric contents. Secondary outcomes included the need for intubation, early procedure termination, and recommendations for repeat endoscopy.
Semaglutide use was an independent predictor of retained solid gastric contents (odds ratio [OR], 4.74; 95% CI, 2.40-9.35; P less than .0001). Multivariable propensity-matched analysis showed a 6% absolute increase in retained gastric contents in the semaglutide group compared to controls (P less than .0001).
This increase appeared clinically relevant, as semaglutide use was associated with a higher rate of early procedure termination (OR, 3.09; P = 0.02) and recommendations for repeat endoscopies (OR, 3.61; P = 0.02), “indicating the degree of retained solid gastric contents was enough to limit the intended gastric mucosal examination,” the investigators wrote.
However, patients who underwent same-day colonoscopy, which included a 24-hour clear liquid fast leading up to the procedure, were less likely to have retained gastric contents (OR, 0.41; 95% CI, 0.23-0.73; P = 0.003), suggesting that extended fasting protocols may mitigate the risk of procedural complications.
“Patients with a history of gastroparesis are often advised to stop ingesting solid foods and maintain a clear liquid diet for a longer period than standard ASA guidance before anesthetized procedures,” Dr. Korlipara and colleagues wrote. “In our opinion, this recommendation should be considered in patients on long-term GLP-1RA therapy, in response to the findings reported in this study and others about the protective effects of a 24-hour liquid fast.”
Point-of-care gastric ultrasound may also be considered to evaluate patients at higher risk of retained stomach contents, they added, especially in patients with additional risk factors for delayed gastric emptying.
“Previously published data have linked prolonged gastric emptying delays in patients chronically using these medications,” they wrote. “Considering the effect on blood sugar and associated procedural risk, especially in patients taking this medication for diabetes management, more studies are warranted to determine the effect of medication on periprocedural complications and recommend repeat evaluation.”
After this study was released, new clinical guidance on the use of GLP-1RAs before surgery was co-published by AGA and four other societies. The guidance notes that, in most cases, patients can continue to take GLP-1RAs, but individual risk factors for complications should be assessed prior to surgery. The guidance cautions that patients at high risk for significant GI side effects should follow a liquid diet for 24 hours before a procedure and the anesthesia plan be adjusted accordingly. In rare cases, the procedure should be delayed.
Dr. Korlipara disclosed no conflicts of interest.

The new guidance, contrasting with earlier recommendations, says these incrementally used agents can be taken up until the day of surgery, but patients are advised to follow a liquid diet for 24 hours before the procedure. The decision to proceed with endoscopy and other procedures should be based on shared decision-making with the patient and interdisciplinary care teams in conjunction with minimization of the aspiration risk from delayed gastric emptying, the guidance stresses.
The five endorsing organizations are the American Society for Metabolic and Bariatric Surgery, American Society of Anesthesiologists (ASA), American Gastroenterological Association, International Society of Perioperative Care of Patients with Obesity, and Society of American Gastrointestinal and Endoscopic Surgeons. The societies emphasize that the statement is intended as guidance only and is not an evidence-based formal guideline.
GLP-1 RAs are known to delay gastric emptying, raising concerns about regurgitation, aspiration, and airway compromise during anesthesia. Rare serious adverse events have also been observed, prompting the ASA in 2023 to recommend holding these agents for 1 week for the injectable form and 1 day for the oral form before all procedures requiring anesthesia. 
That abundance of caution, however, had negative impacts of its own. “This guidance has led to cancellations and postponements of many endoscopic and surgical procedures or required patients to undergo general anesthesia who may otherwise have had their procedures performed under moderate sedation,” said guidance coauthor Allison R. Schulman, MD, MPH, an associate professor of medicine and surgery and chief of endoscopy at the University of Michigan in Ann Arbor. “Nearly all institutions have been forced to revise preprocedural protocols, despite a lack of high-level evidence to suggest that these adjustments are necessary.”
“Studies have yielded mixed results as to whether patients on GLP-1s are at increased risk of these events, and the limited data available are inconsistent,” Schulman said. “As a result, there are inconsistencies in the recommendations from various societies leading to growing uncertainty with proceduralists on how to provide safe, effective, and timely procedural care to patients taking GLP-1 RAs.”
The new joint-society guidance may alleviate some of the uncertainty. Among the recommendations:
- Continuing GLP-1 RAs in the perioperative period should be based on shared decision-making with the patient and all care teams balancing the metabolic need for the GLP-1 RA with individual patient risk.
- Certain variables may increase the risk for delayed gastric emptying and aspiration with the periprocedural use of GLP-1 RAs: escalation phase — This phase vs the maintenance phase is associated with a higher risk for delayed gastric emptying; higher dose — the higher the dose, the greater the risk for gastrointestinal (GI) side effects; weekly dosing — GI side effects are more common with weekly vs daily formulations; presence of GI symptoms — nausea, vomiting, abdominal pain, dyspepsia, and constipation may suggest delayed gastric emptying; and medical problems beyond GLP-1 RA indications with GI effects — assess for such conditions as bowel dysmotility, gastroparesis, and Parkinson’s disease.
- Risk factors should be assessed in advance to allow sufficient time to adjust preoperative care, including diet modification and medication bridging if GLP-1 RA cessation is deemed advisable.
- If retained gastric contents are a concern on the day of a procedure, point-of-care gastric ultrasound could be used to assess aspiration risk, resources permitting.
- The aspiration risk from delayed gastric emptying should be minimized by preoperative diet modification and/or altering the anesthesia plan to consider rapid sequence induction of general anesthesia for tracheal intubation. A 24-hour preoperative liquid diet, as before colonoscopy and bariatric surgery, can be utilized when delayed gastric emptying is a concern.
- When concern about retained gastric contents exists on procedure day, providers should engage patients in a shared decision-making model and consider the benefits and risks of rapid-sequence induction of general anesthesia for tracheal intubation to minimize aspiration risk vs procedure cancellation.
“Safe continuation of surgery and gastrointestinal endoscopy, and prevention of procedure cancellation, for patients on GLP-1 RAs can be prioritized following the recommendations above, as would occur for other patient populations with gastroparesis,” the guidance panel wrote.
Commenting on the statement but not involved in it, David B. Purow, MD, managing director of the Digestive Health Center at Northwell Health/Huntington Hospital in Huntington, New York, said the recommendations will encourage clinicians to be more discerning about actual risk in individual cases rather than follow the previous blanket recommendation to stop these agents before procedures requiring sedation.
While GLP-1 RAs were prescribed for the relatively small number of patients with diabetes, he said, the risk was not apparent but became clearer with the widespread use of these agents for weight loss — often unregulated and undisclosed to care providers.
“The pendulum shifted too far the other way, and now it’s shifted back,” he said in an interview. “The new guidance is great because now we can be more thoughtful about managing individual patients.” He cited, for instance, the recommendations on the greater risk in patients in the dose escalation phase or on higher doses, and the risk-reducing measure of a liquid diet for 24 hours before surgery.
His center is already using point-of-care ultrasound and recently had a case in which a patient who forgot and took his GLP-1 RA before a scheduled procedure was found on ultrasound to have a full stomach. “In some cases, these drugs can cause an almost gastroparesis level of delayed emptying,” Purow said.
Purow thinks this early guidance will probably progress to firm guidelines within a year. Schulman is more cautious. “Our understanding of this complex topic is increasing rapidly, and ongoing clinical research will ultimately lead to evidence-based guidelines in this changing landscape,” she said.
This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors. Schulman is a consultant for Apollo Endosurgery, Boston Scientific, Olympus, Microtech, and Fractyl. Purow had no competing interests to declare.
