Gastric band

Gastric band (LAP-BAND®) surgery requires the surgeon to place an inflatable band around the upper part of the stomach, dividing off a small pouch that holds about one-half cup of food. Unlike bypass surgery or gastric sleeve, the pouch stays connected to the stomach.

Be creating a smaller pouch, the band limits the amount of food that can be eaten at one time. The food still travels through the entire stomach, but you become full sooner and stay full longer. The degree of band tightness affects how much food you can eat and the length of times it takes for food to leave the stomach pouch. As you eat less food, your body will stop storing excess calories and start using its fat as energy supply.

The band allows for normal digestion and absorption. Food passes through the full digestive tract in the usual manner, allowing it to be fully absorbed in the body.
