For many, losing weight is only half the battle. Keeping it off often proves far more difficult, as the body slowly drifts back to old patterns.
Now, researchers are exploring a new approach that could help maintain weight loss even after stopping popular medications.
According to research presented at Digestive Disease Week 2026 and led by Dr. Shelby Sullivan of Dartmouth Health, a minimally invasive procedure targeting the gut may offer a new path forward, reports Science Daily.
A familiar setback
Drugs like Ozempic and similar treatments have reshaped obesity care, helping patients lose significant weight in relatively short timeframes.

However, once treatment ends, many individuals experience a gradual return of the lost weight.
This recurring pattern has raised concerns among clinicians about how to sustain long-term results without continuous medication.
A gut-focused approach
The new method centers on the small intestine, a key organ in regulating metabolism and hormone signals.
The procedure works by renewing part of the intestinal lining through a controlled, minimally invasive technique.

Researchers believe this may help restore the body’s response to food and stabilize weight after medication is discontinued.
Promising early data
Initial findings from a controlled clinical trial suggest clear differences between patients who received the procedure and those who did not.
Participants who underwent the treatment regained significantly less weight over a six-month period.
Key findings include:

- Reduced weight regain after stopping medication
- Greater retention of prior weight loss
- Effects that appear to strengthen over time
The procedure is still under investigation, with larger studies ongoing.
If confirmed, it could provide a new strategy for maintaining weight loss without long-term drug use.
