Compare the physiology of a Roux-en-Y gastric bypass (RYGB) with that of an adjustable gastric band (AGB)
Adjustable gastric band (AGB). A small bracelet-like band is placed around the top of the stomach to restrict the size of the opening from the throat to the stomach, thereby reducing food intake. The size of the opening can be controlled via a balloon inside the band.
Roux-en-Y gastric bypass (RYGB). Food intake is limited as surgeons create a small pouch for the stomach. This pouch is then connected to a different part of the intestine (bypassing the stomach, duodenum), thereby changing the way food is absorbed. The pouch the surgeons create is only about the size of a walnut.
