Gastric Sleeve Surgery
A gastric sleeve, also known as a sleeve gastrectomy, is a newer procedure, and very popular type of weight loss surgery offered around the world. The gastric sleeve procedure is done by removing part of the stomach, approximately 75-80%, and creating a sleeve where the food will go when digested. This “sleeve” becomes the new stomach, as the excess stomach is surgically removed. The gastric sleeve helps the patient feel fuller faster and stay full for longer periods of time. This results in significant weight loss by eating a lower quantity of food.
What to Expect
Unlike some other weight loss procedures, the gastric sleeve is not reversible. This makes it a lifelong commitment and diet to give the best chance of long-term success. The gastric sleeve surgery is performed laparoscopically with a hospital stay of 2-3 days and a recovery time of 2-4 weeks.
While the weight loss in gastric sleeve tends to be slower than gastric bypass, it has better long-term results in many cases. Differentiating from gastric bypass which uses both restriction and malabsorption, the gastric sleeve surgery only uses restriction. The true difference being: gastric sleeve surgery doesn’t bypass the nutrients that are absorbed by the stomach. Therefore, food is still digested normally and essential nutrients are stored in the body.
