Roux-en-Y Gastric Bypass

This surgery reduces the size of your stomach to a small pouch – about the size of an egg by stapling off a section of it. The surgeon then attaches this pouch directly to the small intestine, bypassing most of the rest of the stomach and the upper part of the small intestine.
