CHICAGO – Only 1%-3% of patients who have had bariatric surgery take Food and Drug Administration–approved antiobesity medications even though 25% of patients experience significant weight regain within a few years of surgery, according to a study presented at the annual Digestive Disease Week® meeting.

Obesity is a chronic, relapsing condition that must be treated as such, said the study’s author Stephen A. Firkins, MD, a fellow of gastroenterology and hepatology at the Cleveland Clinic. “Barriers to antiobesity medications must be identified.”

“If a quarter of all patients experience weight regain and another quarter experience insufficient weight loss – but only 5% are being prescribed an FDA-approved AOM – that means there’s underutilization,” Dr. Firkins said.

Data from the National Health and Nutrition Examination Survey show that 30.7% of all men and women in the United States are overweight and of these, 42.4% are obese. For the severely obese, bariatric surgery, including sleeve gastrectomy, Roux-en-Y gastric bypass, and one anastomosis gastric bypass, are viable options with differing degrees of long-term success.

And while antiobesity medications such as orlistat (Xenical, Alli), phentermine/topiramate (Qsymia), naltrexone/bupropion (Contrave), liraglutide (Saxenda), semaglutide (Wegovy), and setmelanotide (Imcivree), may be considered before bariatric surgery, there are questions about the need for its use after surgery.

“While these are often employed or considered presurgically, there is a paucity of literature describing their utilization postsurgically, particularly in regards to newer antiobesity medications such as the [glucagonlike peptide–1] receptor agonists,” Dr. Firkins said.

The aim of Dr. Firkins’ analysis of the large, publicly available IBM Explorys Electronic Health Record, which included 59,160 adult post–bariatric surgery patients, was to identify postoperative weight control medication use and trends among different populations.

He found rates of postsurgical weight control medication use at 8% for topiramate (off label), 2.9% for liraglutide, 1.03% for phentermine/topiramate, 0.95% for naltrexone/bupropion, 0.52% for semaglutide and 0.1% for orlistat. Rates of topiramate use were higher for patients in the 35- 39-year range, and for orlistat and liraglutide in the 65- to 69-year range.

The differences, Dr. Firkins said, were likely related to side-effect profiles and accumulations of comorbidities with advancing age. Black patients were more likely to be prescribed the medications. Also, further analysis showed a significantly higher use of these medications among individuals with hypertension, diabetes, and hyperlipidemia.

The analyses raised several questions for future study, Dr. Firkins said: “What is the optimal timing of antiobesity medication initiation? Is it at the plateau of peak weight loss typically seen at 1-3 years post surgery? Or, after weight is regained? What is the phenotype of patients who are going to be good responders versus poor responders to a particular medication category?”

“Upon recognition of insufficient weight loss/weight regain, a multidisciplinary strategy towards management is warranted, including behavioral and dietary counseling, and consideration of AOM early use, as well as endoscopic or surgical revision,” he said.

Dr. Firkins had no disclosures.
