Gastric Bypass surgery, also known as Bariatric surgery, is performed for weight loss.  There are several variations of this surgery, but in general it makes the stomach smaller so that it cannot take in or process as much food.

The first Gastric Bypass surgery was performed in 1967 at the University of Iowa.
