Gastric Bypass

Last Visited »

Overview

Gastric Bypass, also called Roux-en-Y gastric bypass surgery, calls for the reduction of the size of the stomach pouch. We will then attach a Y-shaped section of the small intestine directly to the newly formed pouch. Doing this allows food to bypass a large portion of the small intestine, which limits the absorption of calories and nutrients. The smaller stomach pouch allows our patients to feel fuller sooner and the body absorbs fewer calories. Gastric bypass patients can expect to lose up to 65% of their excess weight. Of course every procedure is unique so this number will vary.

This procedure is done with a laparoscope (a thin telescope-like instrument for viewing inside the abdomen). This involves using small incisions and has a more rapid recovery time.
