About 1 in every 4 patients who undergo bariatric surgery regains significant amount of weight some time along their journey, posing it as a serious problem that needs to be addressed in a pandemic of obesity. Lifestyle modification, anti-obesity medications, and bariatric endoscopy are multiple therapeutic options that can be used to support any weight loss attempt. A 53-year-old woman with morbid obesity who responded adequately to gastric-bypass regained significant weight 8 years later. We initially approached her post-operative weight regain in a behavioral, pharmacologic non-invasive manner; however, she failed to appropriately respond to several anti-obesity medications. Upper endoscopy revealed a dilated gastric pouch and gastro-jejunal anastomosis (GJA) that was reduced using argon plasma coagulation (APC), but also with a modest response. We then added liraglutide to her APC endo-therapy sessions and subsequentially patient started losing significantly more weight. For selective post-bariatric surgery weight re-gainers, endoscopic and pharmaco-therapy combined may be needed for more effective results.
