Gastric bypass, also called Roux-en-Y, may help improve weight-related complications like diabetes. During gastric bypass surgery, a one-half to one-ounce pouch about the size of an egg is made from the stomach and connected to the rest of the gastrointestinal tract, changing the pathway of the small intestine.
