Gastric Sleeve Surgery v. Gastric Bypass Surgery
While the gastric sleeve permanently removes a large portion of the patient’s stomach, gastric bypass is more complex since it is a multi-step procedure. Gastric sleeve surgery comprises a single step, as it just removes a large portion of the stomach; gastric bypass rearranges the anatomy of the digestive system so that less food is absorbed. Gastric bypass patients can expect to lose between 50-80% of unwanted body weight within the first 12-18 months following surgery. Gastric sleeve patients, on the other hand, lose 60-70% of excess body weight within 12-18 months of surgery. Gastric sleeve, also known as vertical sleeve gastrectomy, is the safest, most widely performed weight loss surgery in the world today. Both revolutionary surgeries in the fight against obesity are designed to help the patient eat considerably less by significantly reducing stomach size. Here’s how each works:

70-80% of the stomach is removed. This also removes much of the cells that produce ghrelin a "hunger hormon." Not only does this allow for limited food intake, but the patient will also not be triggered by an overzealous hunger-stimulating hormone, further promoting weight loss.
- Gastric Bypass
During this procedure, a small stomach pouch is created by stapling across the upper part of the stomach. The newly created stomach pouch is then re-connected to part of the small intestine that is further away. Therefore, the food will "bypass" most of the stomach and part of the small intestine. This leads to less digestion and absorption of food.
- SADI - single anastomosis duodenal bypass
SADI is n alternative procedure which has been shown to promote the most amount of weight loss. It is a combination of the sleeve and bypass. Because
