Laparoscopic Sleeve Gastrectomy is a restrictive bariatric surgery. During this procedure, the surgeon creates a small, sleeve-shaped stomach about the size of a banana. Weight loss occurs because the procedure causes the stomach to tolerate a limited amount of food, causing a feeling of fullness more quickly.

Patients who have a sleeve gastrectomy are encouraged to embrace a change in lifestyle in order to maintain long-term weight loss success. They should also participate in an exercise program and have regular medical care.
