Recently published consensus guidelines for low-dose oral minoxidil (LDOM) treatment of hair loss provide best-practice recommendations in areas ranging from pretreatment considerations and counseling to patient monitoring. With large randomized, controlled trials lacking, the guidelines authors and other dermatologists said the paper provides practical pointers that should increase clinicians’ confidence in prescribing LDOM for hair loss.

Comfort and Confidence

Benjamin N. Ungar, MD, director of the Alopecia Center of Excellence at Mount Sinai Icahn School of Medicine, New York City, said he hopes that the guidelines will “make dermatologists in practice more comfortable with the use of low-dose oral minoxidil to treat different kinds of hair loss, and therefore, more patients will benefit.” He was not an author of the paper, which was published online in JAMA Dermatology on November 20, but was asked to comment.

Members of the multidisciplinary Low-Dose Oral Minoxidil Initiation steering committee recruited dermatologists with hair loss expertise from 12 countries. Using a modified four-round Delphi process that required at least 70% agreement, the group of 43 dermatologists crafted 76 consensus statements. “Notably,” said Co-senior author Jennifer Fu, MD, director of the Hair Disorders Clinic at the University of California, San Francisco, “27 items achieved at least 90% consensus after the first two rounds, indicating broad agreement in expert practice.”

Indications for LDOM

At least 90% of experts concurred regarding the appropriateness of LDOM use for androgenetic alopecia (AGA) and age-related thinning and in cases where topical minoxidil proves ineffective or problematic. Additional situations in which LDOM might provide direct benefit involve follicular miniaturization, such as alopecia areata, or hair cycle disruption, such as chemotherapy. The authors also recommended considering LDOM over topical minoxidil when the latter is more expensive and when patients desire enhanced hypertrichosis.

 

Contraindications and Precautions

Before prescribing LDOM, the authors wrote, clinicians may consult with primary care or cardiology when contraindications (cardiovascular issues, pregnancy/nursing, and potential drug interactions) or precautions (history of tachycardia or arrhythmia, hypotension, or impaired kidney function) exist. Patients with precautions may require blood pressure monitoring, as well as monitoring for adverse effects of treatment. The panel also suggested the latter for all patients at the time of LDOM initiation and dose escalation. The authors advised against routine baseline laboratory and EKG testing in cases without relevant precautions.

Dosing Considerations

Along with systemic adverse event risk and baseline hair loss severity, key dosing considerations include patient age, sex, and whether patients desire hypertrichosis. Consensus on daily doses for adolescent females and males begins at 0.625 mg and 1.25 mg, respectively, and ranges up to 2.5 mg for adolescent females vs 5 mg for adult females and adolescent and adult males.

Presently, said Ungar, many dermatologists — including some who prescribe LDOM — remain uncomfortable even with very low doses, perhaps because of an invalid perception of cardiovascular safety issues including potential hypotension and pericardial effusions. However, recently published data include a review published November 7 in the Journal of the American Academy of Dermatology, which showed no significant effect of LDOM on blood pressure. And in a September Journal of Drugs in Dermatology article the authors found no impact on pericardial effusions in a 100-patient cohort.

Some dermatologists worry about the impact hypertrichosis may have on patients, Ungar added. Although incidence estimates range from 15% to 30%, he said, more than half of his patients experience hypertrichosis. “However, most continue treatment because the beneficial effects outweigh the effect of hypertrichosis.”



 

Practical Roadmap

Adam Friedman, MD, who was not involved with the publication, applauds its inclusion of pragmatic clinical guidance, which he said consensus papers often lack. “This paper sets a great roadmap for working low-dose oral minoxidil into your clinical practice, Friedman, professor and chair of dermatology at George Washington University, Washington, DC, said in an interview.

Rather than limiting LDOM use to AGA, he said, the paper is most helpful in showing the spectrum of disease states for which the expert panel prescribes LDOM. “We use it as adjunctive therapy for many other things, both scarring and nonscarring hair loss,” he added.

In appropriate clinical contexts, the authors wrote, clinicians may consider combining LDOM with spironolactone or beta-blockers. Friedman said that in his hands, combining LDOM with a 5-alpha reductase inhibitor (5ARI) is “absolutely outstanding.” Minoxidil increases blood flow to the scalp, he explained, while 5ARIs prevent production of dihydrotestosterone, which miniaturizes hair.

Fu said, “We hope these consensus outcomes will be helpful to dermatology colleagues as they consider using LDOM to treat hair loss in their adult and adolescent patient populations. We anticipate that these guidelines will be updated as additional evidence-based data emerges and are encouraged that we are already seeing new publications on this topic.”

Important areas for future research, she noted, include pediatric use of LDOM, the comparative efficacy of topical vs oral minoxidil, the safety of oral minoxidil for patients with a history of allergic contact dermatitis to topical minoxidil, and the use of other off-label forms of minoxidil, such as compounded oral minoxidil and sublingual minoxidil.

The study was funded by the University of California, San Francisco, Department of Dermatology Medical Student Summer Research Fellowship Program. Fu reported personal fees from Pfizer, Eli Lilly and Company, and Sun Pharma outside of the study. The full list of author disclosures can be found in the paper. Ungar and Friedman reported no relevant financial relationships.

TOPLINE:

Elevated levels of plasma F2-isoprostanes, a reliable marker of oxidative stress, are associated with an increased risk for fractures in older ambulatory patients with type 2 diabetes (T2D) independently of bone density.

METHODOLOGY:

• Patients with T2D face an increased risk for fractures at any given bone mineral density; oxidative stress levels (reflected in circulating F2-isoprostanes), which are elevated in T2D, are associated with other T2D complications, and may weaken bone integrity.
• Researchers analyzed data from an observational cohort study to investigate the association between the levels of circulating F2-isoprostanes and the risk for clinical fractures in older patients with T2D.
• The data included 703 older ambulatory adults (baseline age, 70-79 years; about half White individuals and half Black individuals ; about half men and half women) from the Health, Aging and Body Composition Study, of whom 132 had T2D.
• Plasma F2-isoprostane levels were measured using baseline serum samples; bone turnover markers were also measured including procollagen type 1 N-terminal propeptide, osteocalcin, and C-terminal telopeptide of type 1 collagen.
• Incident clinical fractures were tracked over a follow-up period of up to 17.3 years, with fractures verified through radiology reports.

TAKEAWAY:

• Overall, 25.8% patients in the T2D group and 23.5% adults in the non-diabetes group reported an incident clinical fracture during a mean follow-up period of 6.2 and 8.0 years, respectively.
• In patients with T2D, the risk for incident clinical fracture increased by 93% for every standard deviation increase in the log F2-isoprostane serum levels (hazard ratio [HR], 1.93; 95% CI, 1.26-2.95; P = .002) independently of baseline bone density, medication use, and other risk factors, with no such association reported in individuals without T2D (HR, 0.98; 95% CI, 0.81-1.18; P = .79).
• In the T2D group, elevated plasma F2-isoprostane levels were also associated with a decrease in total hip bone mineral density over 4 years (r = −0.28; P = .008), but not in the non-diabetes group.
• No correlation was found between plasma F2-isoprostane levels and circulating advanced glycoxidation end-products, bone turnover markers, or A1c levels in either group.

IN PRACTICE:

“Oxidative stress in T2D may play an important role in the decline of bone quality and not just bone quantity,” the authors wrote.

Just a few years after some TikTok videos spiked the demand, one in eight US adults has tried Ozempic (semaglutide) or another drug in its class. Glucagon-like peptide 1 (GLP-1) receptor agonist medications have revolutionized obesity medicine.

But they’re not without problems. In the early days of the social media craze, news reports often featured patients whose gastrointestinal side effects sent them to the emergency room (ER).

“It happened a lot then. Patients didn’t want to complain because they were losing weight, and they wound up in the ER with extreme constipation or a small bowel obstruction,” said Caroline Apovian, MD, co-director of the Center for Weight Management and Wellness at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, Boston.

“But that’s not really happening now,” she added.

Research backs up her assertion: A recent clinical review of studies found that many patients still experience side effects, but only at a mild to moderate level, while the dosage increases — and the unpleasantness tapers with time. Roughly 7% of patients discontinue the medications due to these symptoms.

Here’s what the latest research shows about GLP-1s’ side effects.

 

Most Common: Gastrointestinal Issues

Depending on the symptom and the specific drug, anywhere from one third to one half of patients will experience some kind of stomach trouble.

• In that clinical review, which looked at studies of three GLP-1 medications — semaglutide (Ozempic, Wegovy, Rybelsus), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro, Zepbound) — semaglutide users fared comparatively worse.
• Nausea was reported most frequently — 44.2% of semaglutide users dealt with it, compared with 40.2% for liraglutide and 31% for tirzepatide. Diarrhea, constipation, and vomiting also struck one quarter to one third of semaglutide patients, and slightly fewer for the other two medications.

Apovian finds that careful dosage helps her patients avoid the worst effects.

“We don’t know who’s going to do well and who’s not,” she said. “We start slowly, and usually things go OK.”

If a patient does react poorly, she’ll hold off on increasing the dosage until they acclimate and advise using over-the-counter meds like MiraLAX to address the symptoms.

Few documented severe adverse gastro events appeared in the data, affecting less than 1% of liraglutide and tirzepatide patients and 2.6% of semaglutide users. The majority of these events were gallbladder-related.

 

Questions About Causation: Depression and Suicidality

About a year ago, a study used 18 years’ worth of data from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) to examine how often patients reported suicidal ideation and/or depression while using GLP-1 medications. Compared with metformin and insulin, researchers found disproportionate reporting by patients using semaglutide and liraglutide. Other GLP-1 medications didn’t show this effect. The researchers pointed out: These statistics don’t show causation — there’s no clear reason why those two medications were linked to more reports.

Further research has been more reassuring:

• Another study also used FAERS but looked only at data from 2018 to 2022, when usage of these drugs was ramping up, and found no link between suicidal or self-injurious behaviors and GLP-1.
• A recent cohort study, which looked at data from nearly 300,000 people, found that GLP-1 users aren’t at increased risk for death by suicide.
• Both the FDA and the European Medicines Agency have issued statements that the evidence doesn’t support a causal association.

There are several factors at play here. People with obesity and diabetes are more likely to have depression to begin with. And more importantly, even if there is a link, causality remains unclear. For instance, patients who lose weight via bariatric surgery are at increased risk for depression, substance abuse, and self-harm. These symptoms may be related to the weight loss itself, not the medications.

“Some people use food as something other than nutrition. They use food to soothe other psychological issues,” Apovian said. “When that’s taken away, the psychological issues are still there.”

In her practice, she’s seen the risk for mental health issues rise with more substantial weight loss — 50-100 pounds.

This lack of clarity regarding causation means it’s important to perform a detailed patient history before prescribing, so you can monitor more closely with preexisting psychiatric disorders.

 

Possible Link: Ocular Symptoms

Here, too, the research isn’t definitive but leans toward no clear association. Several studies have looked for a link between GLP-1 and vision-related issues:

• One examined FAERS data and network pharmacology and found semaglutide and lixisenatide were significantly associated with adverse events like blurred vision, visual impairment, and diabetic retinopathy.
• This summer, a cohort study of almost 17,000 people with diabetes or overweight/obesity suggested a link between semaglutide and nonarteritic anterior ischemic optic neuropathy (NAION), a common cause of blindness due to optic nerve damage. The study found “a substantially increased risk of NAION among individuals prescribed semaglutide relative to those prescribed other medications to treat type 2 diabetes and obesity or overweight.”
• But this month, another cohort study with 135,000 participants looked at NAION in people with type 2 diabetes, obesity, or both. It compared results with common non-GLP-1 medications and found just the opposite: No increased risk for NAION.

One drawback with all these studies is that they’re based on large databases rather than randomized controlled trials (RCTs). When researchers focused on RCTs in a 2023 meta-analysis, they found a significant association with only one form of GLP-1, albiglutide — which was withdrawn from the market in 2017. The other six FDA-approved drugs didn’t show a statistically significant link.

 

Possible Trouble: Pulmonary Aspiration Under Sedation

Earlier this month, the FDA updated labeling for semaglutide, liraglutide, and tirzepatide to include a warning about the risk for aspiration during surgery. While there are no published studies, several case reports have appeared.

GLP-1 medications delay gastric emptying, so even though a patient may have fasted before surgery as usual, some food or liquid may remain. In response to this possibility, a group of professional medical societies issued guidelines for using these medications during the perioperative period. They include:

• Consideration of dosage, symptoms, and other medical conditions: The risk is higher during the escalation phase, and in general, higher doses mean higher risk.
• Potential discontinuation of GLP-1 usage when assessment shows an elevated risk.
• Assessment on the day of the procedure for possible delayed gastric emptying.
• Preoperative dietary modifications, which might include switching to a liquid diet.

Rare: Serious Effects

And then there are the outliers, the frightening issues that make headlines. On their own, none of these are common enough to affect consideration of GLP-1 use:

• Studies in rats suggested an increased risk for thyroid cancer, but subsequent research has found no evidence.
• Colonic ischemia in association with tirzepatide.
• Acute pancreatitis leading to death in association with semaglutide.
• Speaking of pancreatitis, that clinical review of studies did find that both liraglutide and semaglutide led to an elevated risk for pancreatitis, bowel obstruction, and gastroparesis. But the numbers were so small as to be insignificant — for instance, just 0.2% of patients experienced pancreatitis.

Benefits Outweigh Risks

When you lay out these side effects against the countless known benefits of weight loss and blood sugar management — the lower risk for high blood pressure, heart disease, stroke, metabolic syndrome, fatty liver disease, several cancers, and more — the advantages of GLP-1 drugs seem clear. Ultimately, of course, it’s the patient’s decision whether to begin and continue taking any medication for a chronic disease.

Apovian recommends having in-depth conversations before you write that first prescription – she compares the situation to using an antihypertensive drug. If your patient understands potential side effects, they’re more likely to maintain long-term compliance.

“We educate our patients how to use these drugs, indefinitely, if you want to maintain a lower, healthier body weight,” she said. “I don’t see patients who stop using them, but they’re out there. These are people desperate to lose weight, who aren’t given the education to understand we’re treating a disease. It’s not a matter of willpower.”

And once a patient starts taking a GLP-1, monitor them closely, with in-person visits rather than telehealth, while increasing the dosage. If they experience side effects, stay at that level until they ease. And if the patient has a good weight-loss response at a lower dose, stay there. Just because you can go higher, it doesn’t mean you should.

Just a few years after some TikTok videos spiked the demand, one in eight US adults has tried Ozempic (semaglutide) or another drug in its class. Glucagon-like peptide 1 (GLP-1) receptor agonist medications have revolutionized obesity medicine.

But they’re not without problems. In the early days of the social media craze, news reports often featured patients whose gastrointestinal side effects sent them to the emergency room (ER).

“It happened a lot then. Patients didn’t want to complain because they were losing weight, and they wound up in the ER with extreme constipation or a small bowel obstruction,” said Caroline Apovian, MD, co-director of the Center for Weight Management and Wellness at Brigham and Women’s Hospital and professor of medicine at Harvard Medical School, Boston.

“But that’s not really happening now,” she added.

Research backs up her assertion: A recent clinical review of studies found that many patients still experience side effects, but only at a mild to moderate level, while the dosage increases — and the unpleasantness tapers with time. Roughly 7% of patients discontinue the medications due to these symptoms.

Here’s what the latest research shows about GLP-1s’ side effects.

 

Most Common: Gastrointestinal Issues

Depending on the symptom and the specific drug, anywhere from one third to one half of patients will experience some kind of stomach trouble.

• In that clinical review, which looked at studies of three GLP-1 medications — semaglutide (Ozempic, Wegovy, Rybelsus), liraglutide (Saxenda, Victoza), and tirzepatide (Mounjaro, Zepbound) — semaglutide users fared comparatively worse.
• Nausea was reported most frequently — 44.2% of semaglutide users dealt with it, compared with 40.2% for liraglutide and 31% for tirzepatide. Diarrhea, constipation, and vomiting also struck one quarter to one third of semaglutide patients, and slightly fewer for the other two medications.

Apovian finds that careful dosage helps her patients avoid the worst effects.

“We don’t know who’s going to do well and who’s not,” she said. “We start slowly, and usually things go OK.”

If a patient does react poorly, she’ll hold off on increasing the dosage until they acclimate and advise using over-the-counter meds like MiraLAX to address the symptoms.

Few documented severe adverse gastro events appeared in the data, affecting less than 1% of liraglutide and tirzepatide patients and 2.6% of semaglutide users. The majority of these events were gallbladder-related.

 

Questions About Causation: Depression and Suicidality

About a year ago, a study used 18 years’ worth of data from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) to examine how often patients reported suicidal ideation and/or depression while using GLP-1 medications. Compared with metformin and insulin, researchers found disproportionate reporting by patients using semaglutide and liraglutide. Other GLP-1 medications didn’t show this effect. The researchers pointed out: These statistics don’t show causation — there’s no clear reason why those two medications were linked to more reports.

Further research has been more reassuring:

• Another study also used FAERS but looked only at data from 2018 to 2022, when usage of these drugs was ramping up, and found no link between suicidal or self-injurious behaviors and GLP-1.
• A recent cohort study, which looked at data from nearly 300,000 people, found that GLP-1 users aren’t at increased risk for death by suicide.
• Both the FDA and the European Medicines Agency have issued statements that the evidence doesn’t support a causal association.

There are several factors at play here. People with obesity and diabetes are more likely to have depression to begin with. And more importantly, even if there is a link, causality remains unclear. For instance, patients who lose weight via bariatric surgery are at increased risk for depression, substance abuse, and self-harm. These symptoms may be related to the weight loss itself, not the medications.

“Some people use food as something other than nutrition. They use food to soothe other psychological issues,” Apovian said. “When that’s taken away, the psychological issues are still there.”

In her practice, she’s seen the risk for mental health issues rise with more substantial weight loss — 50-100 pounds.

This lack of clarity regarding causation means it’s important to perform a detailed patient history before prescribing, so you can monitor more closely with preexisting psychiatric disorders.

 

Possible Link: Ocular Symptoms

Here, too, the research isn’t definitive but leans toward no clear association. Several studies have looked for a link between GLP-1 and vision-related issues:

• One examined FAERS data and network pharmacology and found semaglutide and lixisenatide were significantly associated with adverse events like blurred vision, visual impairment, and diabetic retinopathy.
• This summer, a cohort study of almost 17,000 people with diabetes or overweight/obesity suggested a link between semaglutide and nonarteritic anterior ischemic optic neuropathy (NAION), a common cause of blindness due to optic nerve damage. The study found “a substantially increased risk of NAION among individuals prescribed semaglutide relative to those prescribed other medications to treat type 2 diabetes and obesity or overweight.”
• But this month, another cohort study with 135,000 participants looked at NAION in people with type 2 diabetes, obesity, or both. It compared results with common non-GLP-1 medications and found just the opposite: No increased risk for NAION.

One drawback with all these studies is that they’re based on large databases rather than randomized controlled trials (RCTs). When researchers focused on RCTs in a 2023 meta-analysis, they found a significant association with only one form of GLP-1, albiglutide — which was withdrawn from the market in 2017. The other six FDA-approved drugs didn’t show a statistically significant link.

 

Possible Trouble: Pulmonary Aspiration Under Sedation

Earlier this month, the FDA updated labeling for semaglutide, liraglutide, and tirzepatide to include a warning about the risk for aspiration during surgery. While there are no published studies, several case reports have appeared.

GLP-1 medications delay gastric emptying, so even though a patient may have fasted before surgery as usual, some food or liquid may remain. In response to this possibility, a group of professional medical societies issued guidelines for using these medications during the perioperative period. They include:

• Consideration of dosage, symptoms, and other medical conditions: The risk is higher during the escalation phase, and in general, higher doses mean higher risk.
• Potential discontinuation of GLP-1 usage when assessment shows an elevated risk.
• Assessment on the day of the procedure for possible delayed gastric emptying.
• Preoperative dietary modifications, which might include switching to a liquid diet.

Rare: Serious Effects

And then there are the outliers, the frightening issues that make headlines. On their own, none of these are common enough to affect consideration of GLP-1 use:

• Studies in rats suggested an increased risk for thyroid cancer, but subsequent research has found no evidence.
• Colonic ischemia in association with tirzepatide.
• Acute pancreatitis leading to death in association with semaglutide.
• Speaking of pancreatitis, that clinical review of studies did find that both liraglutide and semaglutide led to an elevated risk for pancreatitis, bowel obstruction, and gastroparesis. But the numbers were so small as to be insignificant — for instance, just 0.2% of patients experienced pancreatitis.

VANCOUVER, BRITISH COLUMBIA — While polypharmacy is inevitable for patients with multiple chronic diseases, not all medications improve patient-oriented outcomes, members of the Patients, Experience, Evidence, Research (PEER) team, a group of Canadian primary care professionals who develop evidence-based guidelines, told attendees at the Family Medicine Forum (FMF) 2024.

In a thought-provoking presentation called “Axe the Rx: Deprescribing Chronic Medications with PEER,” the panelists gave examples of medications that may be safely stopped or tapered, particularly for older adults “whose pill bag is heavier than their lunch bag.”

 

Curbing Cardiovascular Drugs

The 2021 Canadian Cardiovascular Society Guidelines for the Management of Dyslipidemia for the Prevention of Cardiovascular Disease in Adults call for reaching an LDL-C < 1.8 mmol/L in secondary cardiovascular prevention by potentially adding on medical therapies such as proprotein convertase subtilisin/kexin type 9 inhibitors or ezetimibe or both if that target is not reached with the maximal dosage of a statin.

But family physicians do not need to follow this guidance for their patients who have had a myocardial infarction, said Ontario family physician Jennifer Young, MD, a physician advisor in the Canadian College of Family Physicians’ Knowledge Experts and Tools Program.

Treating to below 1.8 mmol/L “means lab testing for the patients,” Young told this news organization. “It means increasing doses [of a statin] to try and get to that level.” If the patient is already on the highest dose of a statin, it means adding other medications that lower cholesterol.

“If that was translating into better outcomes like [preventing] death and another heart attack, then all of that extra effort would be worth it,” said Young. “But we don’t have evidence that it actually does have a benefit for outcomes like death and repeated heart attacks,” compared with putting them on a high dose of a potent statin.

 

Tapering Opioids

Before placing patients on an opioid taper, clinicians should first assess them for opioid use disorder (OUD), said Jessica Kirkwood, MD, assistant professor of family medicine at the University of Alberta in Edmonton, Canada. She suggested using the Prescription Opioid Misuse Index questionnaire to do so.

Clinicians should be much more careful in initiating a taper with patients with OUD, said Kirkwood. They must ensure that these patients are motivated to discontinue their opioids. “We’re losing 21 Canadians a day to the opioid crisis. We all know that cutting someone off their opioids and potentially having them seek opioids elsewhere through illicit means can be fatal.”

In addition, clinicians should spend more time counseling patients with OUD than those without, Kirkwood continued. They must explain to these patients how they are being tapered (eg, the intervals and doses) and highlight the benefits of a taper, such as reduced constipation. Opioid agonist therapy (such as methadone or buprenorphine) can be considered in these patients.

Some research has pointed to the importance of patient motivation as a factor in the success of opioid tapers, noted Kirkwood.

 

Deprescribing Benzodiazepines 

Benzodiazepine receptor agonists, too, often can be deprescribed. These drugs should not be prescribed to promote sleep on a long-term basis. Yet clinicians commonly encounter patients who have been taking them for more than a year, said pharmacist Betsy Thomas, assistant adjunct professor of family medicine at the University of Alberta.

The medications “are usually fairly effective for the first couple of weeks to about a month, and then the benefits start to decrease, and we start to see more harms,” she said.

Some of the harms that have been associated with continued use of benzodiazepine receptor agonists include delayed reaction time and impaired cognition, which can affect the ability to drive, the risk for falls, and the risk for hip fractures, she noted. Some research suggests that these drugs are not an option for treating insomnia in patients aged 65 years or older.

Clinicians should encourage tapering the use of benzodiazepine receptor agonists to minimize dependence and transition patients to nonpharmacologic approaches such as cognitive behavioral therapy to manage insomnia, she said. A recent study demonstrated the efficacy of the intervention, and Thomas suggested that family physicians visit the mysleepwell.ca website for more information.

Young, Kirkwood, and Thomas reported no relevant financial relationships.

Rates of overweight and obesity have more than doubled in the United States during the last three decades, according to a new analysis. By 2050, it’s anticipated that 213 million adults (age, > 25 years) and 43 million children and adolescents will have overweight or obesity. The results led authors of a study to describe obesity as having reached a “crisis point” requiring urgent action and interventions.

Are glucagon-like peptide 1 receptor agonists (GLP-1 RAs), originally developed and prescribed for diabetes and now approved for weight loss, the answer? 

Their popularity is certainly surging. Between the last 6 months of 2022 vs the last 6 months of 2024, the number of patients prescribed GLP-1 RAs increased by 132.6%. This is also reflected in a shift in public awareness, with a recent survey of US adults finding that 32% of respondents had heard “a lot” about these drugs, up from 19% in 2023.

GLP-1 RAs (including tirzepatide, which targets not only the GLP-1 receptor but also the glucose-dependent insulinotropic polypeptide receptor) have shown efficacy in weight loss. A 2022 review and meta-analysis of 22 trials (17,183 patients) found that 50.2% and 17.5% of those treated with GLP-1 RAs had a ≥ 5% and ≥ 10% weight loss, respectively, compared with placebo. A 2023 review of 41 trials (15,135 patients) found that compared with controls, GLP-1 RAs significantly reduced body weight, body mass index, waist circumference, and waist-to-hip ratio.

“GLP-1 RAs are great medications,” Andres Acosta, MD, PhD, director of the Precision Medicine for Obesity Laboratory, Mayo Clinic, Rochester, Minnesota, told Medscape Medical News. “We’ve been using them for almost two decades. But now there’s excitement about their utility in treating obesity.”

 

Treating the Four Categories of Obesity 

Daniel Drucker, MD, senior investigator at the Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada, is a pioneer in diabetes treatment and particularly in the development of GLP-1 RAs. Drucker told Medscape Medical News that despite the efficacy and enormous potential of GLP-1 RAs, “we know some people don’t lose much weight when taking these medicines and others don’t feel well and can’t take them.”

The number of individuals who don’t respond to or aren’t able to tolerate GLP-1 RAs “might be small — less than 10% of people who try to take them — but we don’t fully understand the differences in response across different individuals,” Drucker said.

Acosta agreed, adding that it’s “essential for us to identify who will be the best responders, as we do with medications for other conditions, such as cancer and cardiovascular disease.”

Acosta’s group has spent more than a decade engaged in efforts to identify unique characteristics among patients with obesity and has succeeded in identifying four obesity phenotypes.

“What matters in the space of GLP-1 is that using this classification, we can identify the best responders and those who don’t respond.” 

The first phenotype, described as “Hungry Gut” (HG), includes patients with abnormal postprandial satiety. “Although they may be satiated at the end of a meal, they have accelerated gastric emptying and therefore feel hungry between meals and want to keep eating,” he said.

There are also patients who experience abnormal satiety during meals. According to Acosta, these are the patients who will return to the table for second and third helpings. “They don’t feel full and continue to eat more and more in a single sitting” — a phenomenon referred to as “Hungry Brain.”

The third phenotype — “Emotional Hunger” — consists of people who are “hedonic” about food or engage in emotional eating behavior, whereas in the fourth group, people have “an abnormal metabolism in which they don’t burn enough calories. They have an inefficient metabolic rate.” This latter phenomenon is called “Slow Burn.”

Acosta and colleagues randomized 312 patients attending a weight management center to phenotype-guided or non–phenotype-guided treatment with anti-obesity medications (phentermine, phentermine/topiramate, bupropion/naltrexone, lorcaserin, and liraglutide). The phenotype-guided approach was associated with a 1.75-fold greater weight loss after 1 year than the non–phenotype-guided approach (mean weight loss, 15.9% vs 9.0%, respectively).

 

GLP-1 RAs: Not One-Size-Fits-All

Acosta’s group has developed a genetic test that uses patients’ saliva to identify their obesity phenotype, with the aim of predicting the best responders to GLP-1 RAs. The test, MyPhenome genetic obesity test, is licensed by Acosta’s lab and available through Phenomix Sciences.

Acosta and colleagues presented their findings at the American Gastroenterological Association’s 2024 annual meeting regarding a machine-learning gene risk score (ML-GRS) they developed to predict HG, based on saliva and blood samples. Their genetic studies generated a ML-GRS that classified participants with obesity along a continuum from “HG Positive” (HG+) to “HG Negative” (HG−). Compared with the HG− participants, those who were HG+ had superior total body weight loss with semaglutide at 9 and 12 months. When used to predict response, the ML-GRS had an area under the curve of 0.76 (P = .04) and a positive predictive value of 0.95.

According to Acosta, HG+ patients are “the best responders to the GLP-1 RAs, although we don’t yet understand the mechanism of why they have the phenomenon of abnormal postprandial satiety. It may be an abnormal genetic pathway or abnormal secretion of GLP-1. More studies are needed.”

He noted that GLP-1 RAs “might also be helpful with the second [Hungry Brain] category, but these patients do better with phentermine-topiramate,” as demonstrated in a 2023 study conducted by Acosta and colleagues.

His group has also studied which lifestyle interventions are most effective for each phenotype. “When a unique lifestyle intervention targeting each phenotype was applied, patients lost more weight and had greater metabolic improvement,” he reported.

“Treating obesity no longer needs to be trial-and-error, but should be done using precision medicine because one size doesn’t fit all,” Acosta said.

 

Concerning Side Effects

The popular media has featured stories about individuals who took GLP-1 RAs for weight loss and experienced serious side effects, including a recent account of a British nurse who died after taking tirzepatide. As reported by the BBC, the nurse’s death certificate listed multiple organ failure, septic shock, and pancreatitis as the immediate causes of death, with the “use of prescribed tirzepatide” recorded as a contributing factor. The report went on to note that there were 23 suspected deaths in the United Kingdom tied to semaglutide since 2019.

Beyond brand-name products, there are also risks associated with GLP-1 RAs manufactured by compounding pharmacies. In early November, CNN reported that compounded semaglutide has been linked to at least 10 deaths. Because of a prior shortage of tirzepatide, the US Food and Drug Administration (FDA) had allowed compounding pharmacies to manufacture the drug. In October, the FDA clarified that it won’t take legal action against compounders, even now that the shortage has been resolved.

A pharmacovigilance study using the FDA Adverse Event Reporting System identified “potential safety signals of increased mortality and serious adverse event reporting” associated with certain GLP-1 RAs — especially in younger patients and women (P < .0001 for both groups).

The most common side effects reported with GLP-1 RAs are gastrointestinal events, such as nausea, diarrhea, constipation, and vomiting. Most occur during dose initiation and escalation and wane over the following weeks. However, studies have also reported severe side effects, including a higher risk for pancreatitis, bowel obstruction, and gastroparesis, as well as a significantly higher risk for gallbladder and biliary diseases. In fact, according to one study, patients with diabetes taking GLP-1 RAs reported gastrointestinal-related issues as a “prominent factor” in their decision to discontinue taking these medications.

Several types of cancer are potentially associated with GLP-1 RAs, but findings regarding this potential link have been inconsistent. In a recent review article, Drucker noted there were only inconsistent data linking GLP-1 RAs with thyroid cancer and medullary thyroid cancer and that their potential association with pancreatic has “not been supported by results from randomized controlled trials or real-world data.” 

Concerns have been raised about loss of lean mass and muscle strength and function, especially in older individuals with obesity and advanced liver, cardiovascular, or kidney disease. However, as Drucker pointed out in his review article, muscle function may not correlate with the loss of lean mass. In fact, there are “consistent reductions” in lean mass after bariatric surgery, but “little evidence to date for impairment of muscle function.” He added that newer GLP-1 agents under development for obesity treatment are focusing on “developing complementary therapies that preferentially reduce adipose tissue, while sparing lean mass.”

As covered by Medscape Medical News, there have been reports of potential suicidal ideation associated with GLP-1 RAs. This triggered a 2023 review from the European Medicines Agency. However, recent results from a cohort study and a post hoc analysis of randomized controlled trials concluded that there is no evidence that these drugs increase suicidal ideation or behavior.

In early November, the FDA updated the labels for the GLP-1 RAs to include a warning regarding pulmonary aspiration during general anesthesia or deep sedation. Guidance from a group of societies, led by the American Society of Anesthesiologists, contains recommendations regarding nuances of addressing this concern in surgical patients taking these agents.

 

Not a Standalone Treatment

Marc-Andre Cornier, MD, professor of medicine, James A. Keating Endowed Chair in Diabetes, and director of the Division of Endocrinology, Diabetes and Metabolic Diseases, Department of Medicine, Medical University of South Carolina, Charleston, South Carolina, told Medscape Medical News that GLP-1 RAs should not be viewed as cosmetic interventions but rather as medical treatments, “not only for weight loss but to reverse obesity-associated complications.” 

Moreover, they should be used “as an adjunct to lifestyle changes,” emphasized Cornier. “We want our patients to have a high-quality diet with high protein content, fluid, vitamins, and minerals, and we want them to exercise.” Especially with the concern of potential loss of muscle mass with these agents, “resistance exercise might help mitigate that concern.”

Recently published recommendations can assist clinicians in guiding patients taking GLP-1 RAs to optimize nutrition. The recommendations note that patients should be referred to a registered dietitian to “complement and support” treatment with anti-obesity medications.

 

What Do Patients Want?

Despite the ever-rising popularity of GLP-1 RAs, a new national survey of over 2200 US adults conducted by the Physicians Committee for Responsible Medicine suggests that most Americans don’t want to use them. Among those who wanted to lose weight, almost three-quarters “disagreed” or “strongly disagreed” with the idea of taking a weight-loss injectable, and 68% of those who wanted to lose weight “agreed” or “strongly agreed” that they would be willing to try a plant-based diet, if it could lead to significant weight loss.

Moreover, many individuals treated with GLP-1 RAs discontinue their use, despite the probability of regaining the weight, according to a report that found only 46.3% of GLP-1 users were still taking the medications at 6 months and only 32.3% at 1 year. The authors commented that their real-world findings show a “substantially lower” 1-year persistence rate, compared with the rate reported in clinical trials. They suggest that the financial burden (> $12,000/year) may contribute to discontinuation.

Discontinuation of GLP-1 RAs can lead to worsening cardiometabolic parameters, with a potential increased risk for adverse outcomes; moreover, weight cycling (“yo-yo dieting”) carries its own risks. In light of these concerns, it’s particularly important to select appropriate patients and to determine whether potential short-term therapy has any enduring benefit.

Acosta agreed. “It’s exciting when looking at the data on how to find the best responders and who should make the effort to take these medications — not only in terms of side effects but also in terms of cost and which patients will receive maximum benefits and should be covered by insurance.”

Rates of overweight and obesity have more than doubled in the United States during the last three decades, according to a new analysis. By 2050, it’s anticipated that 213 million adults (age, > 25 years) and 43 million children and adolescents will have overweight or obesity. The results led authors of a study to describe obesity as having reached a “crisis point” requiring urgent action and interventions.

Are glucagon-like peptide 1 receptor agonists (GLP-1 RAs), originally developed and prescribed for diabetes and now approved for weight loss, the answer? 

Their popularity is certainly surging. Between the last 6 months of 2022 vs the last 6 months of 2024, the number of patients prescribed GLP-1 RAs increased by 132.6%. This is also reflected in a shift in public awareness, with a recent survey of US adults finding that 32% of respondents had heard “a lot” about these drugs, up from 19% in 2023.

GLP-1 RAs (including tirzepatide, which targets not only the GLP-1 receptor but also the glucose-dependent insulinotropic polypeptide receptor) have shown efficacy in weight loss. A 2022 review and meta-analysis of 22 trials (17,183 patients) found that 50.2% and 17.5% of those treated with GLP-1 RAs had a ≥ 5% and ≥ 10% weight loss, respectively, compared with placebo. A 2023 review of 41 trials (15,135 patients) found that compared with controls, GLP-1 RAs significantly reduced body weight, body mass index, waist circumference, and waist-to-hip ratio.

“GLP-1 RAs are great medications,” Andres Acosta, MD, PhD, director of the Precision Medicine for Obesity Laboratory, Mayo Clinic, Rochester, Minnesota, told Medscape Medical News. “We’ve been using them for almost two decades. But now there’s excitement about their utility in treating obesity.”

 

Treating the Four Categories of Obesity 

Daniel Drucker, MD, senior investigator at the Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital, Toronto, Ontario, Canada, is a pioneer in diabetes treatment and particularly in the development of GLP-1 RAs. Drucker told Medscape Medical News that despite the efficacy and enormous potential of GLP-1 RAs, “we know some people don’t lose much weight when taking these medicines and others don’t feel well and can’t take them.”

The number of individuals who don’t respond to or aren’t able to tolerate GLP-1 RAs “might be small — less than 10% of people who try to take them — but we don’t fully understand the differences in response across different individuals,” Drucker said.

Moreover, they should be used “as an adjunct to lifestyle changes,” emphasized Cornier. “We want our patients to have a high-quality diet with high protein content, fluid, vitamins, and minerals, and we want them to exercise.” Especially with the concern of potential loss of muscle mass with these agents, “resistance exercise might help mitigate that concern.”

Recently published recommendations can assist clinicians in guiding patients taking GLP-1 RAs to optimize nutrition. The recommendations note that patients should be referred to a registered dietitian to “complement and support” treatment with anti-obesity medications.

 

What Do Patients Want?

Despite the ever-rising popularity of GLP-1 RAs, a new national survey of over 2200 US adults conducted by the Physicians Committee for Responsible Medicine suggests that most Americans don’t want to use them. Among those who wanted to lose weight, almost three-quarters “disagreed” or “strongly disagreed” with the idea of taking a weight-loss injectable, and 68% of those who wanted to lose weight “agreed” or “strongly agreed” that they would be willing to try a plant-based diet, if it could lead to significant weight loss.

Moreover, many individuals treated with GLP-1 RAs discontinue their use, despite the probability of regaining the weight, according to a report that found only 46.3% of GLP-1 users were still taking the medications at 6 months and only 32.3% at 1 year. The authors commented that their real-world findings show a “substantially lower” 1-year persistence rate, compared with the rate reported in clinical trials. They suggest that the financial burden (> $12,000/year) may contribute to discontinuation.

Discontinuation of GLP-1 RAs can lead to worsening cardiometabolic parameters, with a potential increased risk for adverse outcomes; moreover, weight cycling (“yo-yo dieting”) carries its own risks. In light of these concerns, it’s particularly important to select appropriate patients and to determine whether potential short-term therapy has any enduring benefit.

Acosta agreed. “It’s exciting when looking at the data on how to find the best responders and who should make the effort to take these medications — not only in terms of side effects but also in terms of cost and which patients will receive maximum benefits and should be covered by insurance.”

TOPLINE:

The increase in incidence of pancreatic cancer among young Americans is largely caused by improved detection of early-stage endocrine cancer, not an increase in pancreatic adenocarcinoma. Given the stable mortality rates in this population, the increase in incidence likely reflects previously undetected cases instead of a true rise in new cases, researchers say.

METHODOLOGY:

• Data from several registries have indicated that the incidence of pancreatic cancer among younger individuals, particularly women, is on the rise in the United States and worldwide.
• In a new analysis, researchers wanted to see if the observed increase in pancreatic cancer incidence among young Americans represented a true rise in cancer occurrence or indicated greater diagnostic scrutiny. If pancreatic cancer incidence is really increasing, “incidence and mortality would be expected to increase concurrently, as would early- and late-stage diagnoses,” the researchers explained.
• The researchers collected data on pancreatic cancer incidence, histology, and stage distribution for individuals aged 15-39 years from US Cancer Statistics, a database covering almost the entire US population from 2001 to 2020. Pancreatic cancer mortality data from the same timeframe came from the National Vital Statistics System.
• The researchers looked at four histologic categories: Adenocarcinoma, the dominant pancreatic cancer histology, as well as more rare subtypes — endocrine and solid pseudopapillary — and “other” category. Researchers also categorized stage-specific incidence as early stage (in situ or localized) or late stage (regional or distant).

TAKEAWAY:

• The incidence of pancreatic cancer increased 2.1-fold in young women (incidence, 3.3-6.9 per million) and 1.6-fold in young men (incidence, 3.9-6.2 per million) between 2001 and 2019. However, mortality rates remained stable for women (1.5 deaths per million; annual percent change [AAPC], −0.5%; 95% CI, –1.4% to 0.5%) and men (2.5 deaths per million; AAPC, –0.1%; 95% CI, –0.8% to 0.6%) over this period.
• Looking at cancer subtypes, the increase in incidence was largely caused by early-stage endocrine cancer and solid pseudopapillary neoplasms in women, not adenocarcinoma (which remained stable over the study period).
• Looking at cancer stage, most of the increase in incidence came from detection of smaller tumors (< 2 cm) and early-stage cancer, which rose from 0.6 to 3.7 per million in women and from 0.4 to 2.2 per million in men. The authors also found no statistically significant change in the incidence of late-stage cancer in women or men.
• Rates of surgical treatment for pancreatic cancer increased, more than tripling among women (from 1.5 to 4.7 per million) and more than doubling among men (from 1.1 to 2.3 per million).

IN PRACTICE:

“Pancreatic cancer now can be another cancer subject to overdiagnosis: The detection of disease not destined to cause symptoms or death,” the authors concluded. “Although the observed changes in incidence are small, overdiagnosis is especially concerning for pancreatic cancer, as pancreatic surgery has substantial risk for morbidity (in particular, pancreatic fistulas) and mortality.”

SOURCE:

The study, with first author Vishal R. Patel, MD, MPH, and corresponding author H. Gilbert Welch, MD, MPH, from Brigham and Women’s Hospital, Boston, was published online on November 19 in Annals of Internal Medicine.

LIMITATIONS:

The study was limited by the lack of data on the method of cancer detection, which may have affected the interpretation of the findings.

This transcript has been edited for clarity. 

Recently, there have been two somewhat conflicting recommendations about how to deal with our patients who are on incretin hormone therapy before undergoing elective surgical procedures. 

First, the FDA [Food and Drug Administration] has updated the package inserts for all of these incretins, meaning the glucagon-like peptide-1 (GLP-1) receptor agonists and the dual glucose-dependent insulinotropic (GIP)/GLP-1 receptor agonist tirzepatide, with a warning about pulmonary aspiration during general anesthesia or deep sedation. They instruct patients to let healthcare providers know of any planned surgeries or procedures. This has come about because of postmarketing experience in which patients who are on GLP-1 receptor agonists have had residual gastric contents found despite reported adherence to preoperative fasting recommendations.

The problem with this is that the FDA says they don’t really actually know what to tell us to do or not to do because we don’t have knowledge as to how to truly mitigate the risk for pulmonary aspiration during general anesthesia or deep sedation. They don’t know if modifying preoperative fasting recommendations should be changed or if temporary discontinuation of the drugs could reduce this problem. They really don’t know what to tell us to do except to tell us that this is a problem we should discuss with our patients. 

At about the same time, a society guideline— and this was from a number of different societies, including the American Society of Anesthesiologists — stated that most patients should continue taking their GLP-1 receptor agonist before elective surgery.

This struck me as somewhat discordant from what the FDA said, although the FDA also says they don’t know quite what to tell us to do. This clinical guideline goes into a bit more detail, and what they think might be a good idea is that patients who are at the highest risk for GI side effects should follow a liquid diet for 24 hours before the procedure.

They basically look at who is at highest risk, and they say the following: Patients in the escalation phase of their incretin therapy — that is, early in treatment when the dose is increasing — are most likely to have delays in gastric emptying because that effect is lessened over time. They say that the elective surgery should be deferred until the escalation phase has passed and the GI symptoms have dissipated.

They’re very clear that patients who have significant GI symptoms, including nausea, vomiting, abdominal pain, constipation, and shortness of breath, should wait until their symptoms have dissipated. 

They think this is something that would be good no matter what dose of drug these patients are on. They do say that you tend to see more issues with gastric emptying in patients at the highest dose of a GLP-1 receptor agonist. They also mention other medical conditions that may slow gastric emptying, such as Parkinson’s disease, which may further modify the perioperative management plan. 

Their proposed solutions that sort of correspond with my proposed solutions include assessing the patient. Obviously, if a patient is going up on the dose of these drugs or having many GI side effects, that’s someone who you probably don’t want to send for elective surgery if you don’t have to. However, if you need to — and possibly in everybody — you might want to withhold the drug for 10-14 days preoperatively to make sure they don’t have significant GI side effects as they’re preparing for their procedure.

One of the things the anesthesiology group was worried about was that glucose levels would go up and patients would have hyperglycemia going into surgery. I’m not so worried about holding a dose or two of one of these agents. I don’t see much hyperglycemia occurring. If it does, you can treat it in other ways. 

If it’s somebody where you think they’re having symptoms but they want to have the procedure anyway, you can put them on a liquid diet for 24 hours or so, so that there’s less of a risk for retained gastric contents, at least solid gastric contents. Anesthesiologists can help with this as well because in many cases, they can do a point-of-care gastric ultrasound to check for retained food or fluid. 

I know this is sort of vague because I don’t have clear recommendations, but I do think it’s important to talk with your patients to assess whether they’re having signs or symptoms of gastroparesis. I think it’s not unreasonable to hold the incretin hormone therapy for one or two doses before a procedure if you have that opportunity, and be sure that the anesthesiologist and surgery team are aware of the fact that the patient has been on one of these agents so that they’re a little more aware of the risk for aspiration.

They also mention other medical conditions that may slow gastric emptying, such as Parkinson’s disease, which may further modify the perioperative management plan. 

Their proposed solutions that sort of correspond with my proposed solutions include assessing the patient. Obviously, if a patient is going up on the dose of these drugs or having many GI side effects, that’s someone who you probably don’t want to send for elective surgery if you don’t have to. However, if you need to — and possibly in everybody — you might want to withhold the drug for 10-14 days preoperatively to make sure they don’t have significant GI side effects as they’re preparing for their procedure.

One of the things the anesthesiology group was worried about was that glucose levels would go up and patients would have hyperglycemia going into surgery. I’m not so worried about holding a dose or two of one of these agents. I don’t see much hyperglycemia occurring. If it does, you can treat it in other ways. 

If it’s somebody where you think they’re having symptoms but they want to have the procedure anyway, you can put them on a liquid diet for 24 hours or so, so that there’s less of a risk for retained gastric contents, at least solid gastric contents. Anesthesiologists can help with this as well because in many cases, they can do a point-of-care gastric ultrasound to check for retained food or fluid. 

I know this is sort of vague because I don’t have clear recommendations, but I do think it’s important to talk with your patients to assess whether they’re having signs or symptoms of gastroparesis. I think it’s not unreasonable to hold the incretin hormone therapy for one or two doses before a procedure if you have that opportunity, and be sure that the anesthesiologist and surgery team are aware of the fact that the patient has been on one of these agents so that they’re a little more aware of the risk for aspiration.

Recently, there have been two somewhat conflicting recommendations about how to deal with our patients who are on incretin hormone therapy before undergoing elective surgical procedures. 

First, the FDA [Food and Drug Administration] has updated the package inserts for all of these incretins, meaning the glucagon-like peptide-1 (GLP-1) receptor agonists and the dual glucose-dependent insulinotropic (GIP)/GLP-1 receptor agonist tirzepatide, with a warning about pulmonary aspiration during general anesthesia or deep sedation. They instruct patients to let healthcare providers know of any planned surgeries or procedures. This has come about because of postmarketing experience in which patients who are on GLP-1 receptor agonists have had residual gastric contents found despite reported adherence to preoperative fasting recommendations.

The problem with this is that the FDA says they don’t really actually know what to tell us to do or not to do because we don’t have knowledge as to how to truly mitigate the risk for pulmonary aspiration during general anesthesia or deep sedation. They don’t know if modifying preoperative fasting recommendations should be changed or if temporary discontinuation of the drugs could reduce this problem. They really don’t know what to tell us to do except to tell us that this is a problem we should discuss with our patients. 

At about the same time, a society guideline— and this was from a number of different societies, including the American Society of Anesthesiologists — stated that most patients should continue taking their GLP-1 receptor agonist before elective surgery.

This struck me as somewhat discordant from what the FDA said, although the FDA also says they don’t know quite what to tell us to do. This clinical guideline goes into a bit more detail, and what they think might be a good idea is that patients who are at the highest risk for GI side effects should follow a liquid diet for 24 hours before the procedure.

They basically look at who is at highest risk, and they say the following: Patients in the escalation phase of their incretin therapy — that is, early in treatment when the dose is increasing — are most likely to have delays in gastric emptying because that effect is lessened over time. They say that the elective surgery should be deferred until the escalation phase has passed and the GI symptoms have dissipated.

They’re very clear that patients who have significant GI symptoms, including nausea, vomiting, abdominal pain, constipation, and shortness of breath, should wait until their symptoms have dissipated. 

They think this is something that would be good no matter what dose of drug these patients are on. They do say that you tend to see more issues with gastric emptying in patients at the highest dose of a GLP-1 receptor agonist. They also mention other medical conditions that may slow gastric emptying, such as Parkinson’s disease, which may further modify the perioperative management plan. 

Their proposed solutions that sort of correspond with my proposed solutions include assessing the patient.
