Summary

This study looks at whether a specific blood protein, apolipoprotein, can predict how much weight people lose after sleeve gastrectomy surgery for severe obesity. Researchers will measure protein levels before surgery and track weight loss for 8 months in 110 adults. The goal is to find a protein level that helps doctors decide who will benefit most from surgery versus non-surgical weight loss methods.
