Summary

This study aims to find out why some people lose more weight than others after a minimally invasive stomach-shrinking procedure called endoscopic sleeve gastroplasty. Researchers will follow 205 obese adults for 12 months, measuring weight, blood markers, and gut bacteria changes. The goal is to better predict who will benefit most from this surgery.
