Roux-en-Y gastric bypass (RYGB), often called gastric bypass, is considered the "gold standard" of bariatric surgery.

​

This surgery limits the amount of food you can eat, and it also affects how food is digested and nutrients are absorbed.

 

The procedure involves creating a gastric reservoir from a small portion of the stomach and attaching it directly to the small intestine, thus preventing the passage of food through a large part of the stomach and duodenum. Thus, not only is a gastric reservoir too small to hold large amounts of food, but the absorption of nutrients is substantially reduced by avoiding passage through the small intestine.
