What Is the Average Weight Loss after Gastric Sleeve?

March 2nd, 2012 - Posted to Weight Loss

Sleeve gastrectomy is a surgical procedure generally performed on people who are morbidly obese. That means people BMIs of 40 or higher. It is one of several bariatric surgery options available at Marina Weight Loss.

How Is Gastric Sleeve Performed?

Gastric sleeve surgery works by removing about three-quarters of the stomach. (The suffix "– ectomy" means to remove.) The remaining stomach is much smaller, and holds less food, so the patient becomes full much faster. This allows the patient to eat less while still feeling satisfied, which creates a calorie deficit — in other words, more calories are burned than consumed — leading to weight loss.

If a patient follows the doctor's recommendations for diet and exercise, he or she can continue to lose weight for years following surgery and maintain that weight loss for 10 or more years. On average, gastric sleeve patients lose 55 percent of their excess weight within 18 months following surgery.[1]
