Bariatric Surgery Types
Roux-en-Y Gastric Bypass Surgery
Often simply called "Gastric Bypass," this surgery is a combination method and is the most common bariatric procedure in the U.S. Gastric Bypass surgery creates a small pouch at the top of the stomach and adds a bypass around a segment of the small intestine. This redirects food intake, bypassing most of the stomach and the first section of the small intestine, called the duodenum.
Instead, food enters directly into the second part of the small intestine, called the jejunum, limiting the patient's ability to absorb calories.
The procedure places a band around the upper stomach to decrease food intake. The procedure has less risk and is reversible, and is also the fastest-growing weight loss procedure in the U.S.
The patient does not lose weight as fast, however, compared to Roux-en-Y surgery.
