Restrictive weight loss surgery 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 1 ounce of food and later expands to 2-3 ounces. The lower outlet of the pouch usually has a diameter of only about 3/4 inch. This small outlet delays the emptying of food from the pouch and prolongs the feeling of fullness.

As a result of this surgery, most people lose the ability to eat large amounts of food at one time. After an operation, the person usually can eat only 3/4-1 cup of food without discomfort or nausea. Also, food has to be well chewed.

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.

Restrictive weight loss surgery operations for obesity include Adjustable Gastric Banding (AGB) and Vertical Banded Gastroplasty (VBG).
