The Sleeve Gastrectomy is now the most often performed weight loss surgery worldwide. During the procedure, the bariatric surgeon removes about 80% of the stomach, leaving a small, "sleeve-shaped" stomach.

The sleeve gastrectomy differs from the Roux-en-Y gastric bypass in that no alterations are made to the small intestine, so the gastrointestinal tract remains in continuity. Therefore, there is much less concern for malabsorption of food and vitamins compared with the bypass.

While the sleeve gastrectomy has not been performed as a stand-alone procedure for as long as the Roux-en-Y gastric bypass, it has been shown to produce similar outcomes including:

  • Weight loss

  • Improvement of type 2 diabetes

  • Lowered blood pressure

  • Lowered cholesterol levels



For many years the Roux-en-Y gastric bypass was the gold standard of bariatric surgery. During the Roux-en-Y gastric bypass procedure, a small upper stomach pouch (about the size of a golf ball) is created, dividing it from the lower stomach.

Food will only come into the smaller pouch, which limits the volume of food that a patient can eat and encourages weight loss. The small intestine is also divided so that food "bypasses" the lower stomach and first part of the small intestine. This results in the "Y" shape.

The Roux-en-Y gastric bypass is the bariatric procedure with the longest history of success for weight loss. The procedure also affects the body's metabolism, which can lead to health changes like:​

  • Improvement of type 2 diabetes

  • Lowered blood pressure

  • Lowered cholesterol
