The laparoscopic sleeve gastrectomy weight loss surgery is the most popular weight loss surgery. This procedure reduces the size of the stomach, making you feel full after eating only small portions. Approximately 75-85% of the stomach is removed, leaving behind a smaller, tube-shaped stomach (or “sleeve”). This limits the amount of food that is required to feel full. In addition, the portion of the stomach that makes the hormone Ghrelin, which is responsible for making us feel hungry, is removed.
Advantages of this weight loss surgery procedure include no implantation of an artificial device, no re-routing of the intestinal tract, and less frequent follow-up as compared to the gastric band.
Expected weight loss is 60 - 75 percent excess body weight.
