Gastric bypass is among the most common and successful obesity procedures performed in the United States. It works by changing your digestive system, often limiting the amount of food you can eat.
During this procedure, your surgeon will create a small stomach pouch to restrict food intake. Then, a Y-shaped section of small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). This reduces the amount of calories and nutrients the body absorbs.
Please consult with your surgeon about the advantages, disadvantages, and risks about this procedure.
