Researchers report a minimally invasive procedure may assist patients maintain weight loss after stopping Ozempic or Wegovy.
Duodenal mucosal resurfacing shows early promise in weight maintenance
The procedure, which uses controlled heat to renew the intestinal lining, was tested in a blinded, randomized trial involving 45 participants who had previously lost at least 15% of their body weight using tirzepatide. After stopping the medication, those who received the actual treatment regained significantly less weight than the control group that underwent a sham procedure. Patients with more extensive resurfacing regained only about seven pounds and retained over 80% of their initial weight loss, while the control group regained roughly twice as much.
Weight regain is common after stopping GLP-1 medications
About 70% of people who discontinue drugs like Ozempic or semaglutide eventually regain much of the weight they lost, often within 18 months, according to the study background. Nearly one in five adults with obesity has used a GLP-1 receptor agonist, underscoring the scale of the challenge in sustaining metabolic benefits after medication cessation. Lead author Shelby Sullivan noted that cost, side effects, or reluctance to take long-term drugs drive many patients to stop these therapies, only to lose the gains achieved.
How the gut reset procedure works
Duodenal mucosal resurfacing ablates the damaged mucosal layer of the duodenum, the first section of the small intestine, to stimulate the growth of healthier tissue. Investigators hypothesize this renewal triggers a lasting metabolic reset that helps the body regulate weight without ongoing medication. The ongoing REMAIN-1 trial is designed to confirm whether this intestinal renewal can sustain weight loss after stopping GLP-1 therapies such as semaglutide or tirzepatide.
What is duodenal mucosal resurfacing?
It is an investigational endoscopic treatment that applies controlled heat to remove unhealthy tissue from the duodenum’s lining, promoting the regeneration of a healthier mucosal layer.
How much weight did participants regain after the procedure?
Those who received the actual treatment regained about seven pounds on average and kept more than 80% of their weight loss, while the control group regained roughly twice as much.
