Adjustable gastric banding is a minimally-invasive procedure in which an inflatable silicone band is implanted into the abdomen. The band fastens around the upper stomach to create a tiny, new stomach pouch that limits and controls the amount of food you eat. There is no cutting, stapling or stomach re-routing, so this method is considered the least traumatic of all weight loss surgeries. It is also the only adjustable weight loss surgery, as the band can be adjusted for a customized weight-loss rate. This process takes much longer for desired weight loss results as the band must be adjusted over time.

During the procedure, surgeons usually use laparoscopic techniques (using small incisions and long-shafted instruments), to implant an inflatable silicone band into the patient's abdomen. Like a wristwatch, the band is fastened around the upper stomach to create a new, tiny stomach pouch that limits and controls the amount of food you eat. It also creates a small outlet that slows the emptying process into the stomach and the intestines. As a result, patients experience an earlier sensation of fullness and are satisfied with smaller amounts of food. This results in weight loss.

Approved by the FDA in June 2001, the BioEnterics LAP-BAND Adjustable Gastric Banding System is the only adjustable surgical treatment for morbid obesity in the United States. It induces weight loss by reducing the capacity of the stomach, which restricts the amount of food that can be consumed. Since its clinical introduction in 1993, more than 100,000 LAP-BAND procedures have been performed around the world.
