Roux-en-Y Gastric Bypass

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
