Restrictive operations serve only to restrict food intake and do not interfere with the normal digestive process. To perform the surgery, doctors create a small pouch at the top of the stomach where food enters from the esophagus. Initially, the pouch holds about one ounce of food and later expands to hold more. The lower outlet of the pouch has a small opening to delay the emptying of food from the pouch and cause a feeling of fullness.
Restrictive operations for obesity include the Adjustable Gastric Ban (LAP-BAND), which restricts the size of the stomach using a band.
Although restrictive operations lead to weight loss in almost all patients, they are less successful than malabsorptive operations in achieving substantial, long-term weight loss. Some patients regain weight. Others are unable to adjust their eating habits and fail to lose the desired weight. Successful results depend on the patient's willingness to adopt a long-term plan of healthy eating and regular physical activity.
