In this procedure, a hollow band made of special material is placed around the stomach near its upper end, creating the small pouch and a narrow passage into the larger remaining portion of the stomach.

This small passage delays the emptying of food from the pouch and causes a feeling of fullness.

The band can be tightened or loosened over time to change the size of the passage.

Initial pouch size is approximately 15cc. 

You will feel full more quickly than when your stomach was its original size, which reduces the amount of food you eat and thus the calories consumed.

Bypassing part of the intestine also results in fewer calories being absorbed. This leads to weight loss.

The Medial Gastric Bypass is a more malabsorptive procedure that leaves a 150cm common channel.

Initial pouch size is approximately 15cc. 

In this procedure, a larger portion of the stomach is left intact, including the pyloric valve that regulates the release of contents from the stomach into the small intestine.

The Duodenal Switch is the most malabsorptive procedure, leaving a 120cm common channel.
