Gastric bypass works by reducing the size of the stomach as well as changing the way your body absorbs calories and nutrients. The intestines are rerouted and a small pouch is created by stapling off the main portion of the stomach. This causes food to bypass the main portion of the stomach by emptying slowly into the small intestine, where it is absorbed. Additionally, gastric bypass helps to reduce hunger, aiding in major weight loss. Gastric bypass patients can expect to lose half to two-thirds of their excess body weight within two years of surgery.[Close Div]

LAP-BAND® surgery involves placing an adjustable band around the upper stomach to restrict food intake. This creates a small pouch and a narrow passage to the lower stomach. This small passage delays the emptying of food from the pouch and causes satiety. This gastric band is completely adjustable, so it can be tightened or loosened over time to change the size of the passage as needed.[Close Div]

Sleeve gastrectomy (known by many as “gastric sleeve”) is a restrictive procedure that permanently reduces the size of the stomach. During the procedure, the surgeon removes a large portion of the stomach, leaving behind a thin “sleeve” that holds about 15% as much as the original stomach. The procedure leaves the stomach openings intact so that digestion occurs normally. Sleeve gastrectomy is typically performed as a stand-alone procedure but can be the first of a two-part treatment for the duodenal switch.[Close Div]

The Biliopancreatic Diversion with Duodenal Switch (BPD/DS) is used on those with a smaller stomach and combines a lower restriction and a high level of malabsorption. The outer margin of the stomach is removed (approximately two thirds—similar to a sleeve gastrectomy) and the intestines are then rearranged so that the area where the food mixes with the digestive juices is short.[Close Div]

The BPD/DS is a pyloric saving procedure, which eliminates the “dumping syndrome” that is inherent to gastric bypass procedures.The procedure allows for increased malabsorption, resulting in increased weight loss.
