The Roux-en-Y Gastric Bypass – often called gastric bypass

There are two components to this procedure. First, a small stomach pouch, approximately one ounce or 30 milliliters in volume (about the size of a golf ball), is created by dividing the top of the stomach from the rest of the stomach.

The second component is malabsorption; this occurs due to the bypassing of a major portion of the small intestine. This rerouting of the food stream produces changes in gut hormones that promote fullness, suppress hunger, and reverses one of the primary causes of Type II Diabetes.
