.: Gastric bypass surgery is a restrictive and malabsorptive procedure to help lose weight. Restrictive is in the fact that the stomach is down sized to a 2 oz pouch and malabsorptive is in bypassing part of the stomach and 100 to 150 cm of the small bowel before digestion start.

Stomach and bowel: Basically we take your stomach from the size of football and cut it down to the size of a golf ball. Then we take your small intestine and re-route them so we literally 'bypass' your stomach and duodenum. Expected weight loss is about 70-80% excess weight loss. Also had advantage of excellent resolution of diabetes and high blood pressure.
