New study tests safer version of Weight-Loss surgery against gold standard

NCT ID NCT06057597

First seen Nov 24, 2025 · Last updated May 13, 2026 · Updated 21 times

Summary

This study compares two weight-loss surgeries for people with severe obesity: the standard Roux-en-Y gastric bypass and a newer omega gastric bypass with a shorter intestinal loop. About 368 adults aged 18-65 will be followed for 2 years to see if the omega bypass works as well for weight loss and causes fewer nutritional problems. The goal is to find a simpler, safer option that still provides lasting results.
