Gastric bypass operations that restrict food intake and cause malabsorption result in more weight-loss than those operations that only restrict food intake. Patients who have bypass operations generally lose two–thirds (80%) of their excess weight within two years.
Weight-Loss Surgery Treatments
Gastric sleeve surgery or sleeve gastrectomy involves stapling approximately 70-80 percent of the stomach's natural capacity without involving the intestinal tract.
The LAP–BAND is an inflatable and adjustable gastric band designed to induce weight-loss, without stapling or cutting of the stomach or intestines.
