This operation is performed using the laproscopic or robotic-assisted technique.
In a Roux-en-Y gastric bypass, the stomach is made smaller by creating a small pouch at the top of the stomach using surgical staples.
The smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum).
How Roux-en-Y Helps You Lose Weight
Roux-en-Y results in a smaller stomach and lets food bypass part of the small intestine. The feeling of being full comes much quicker than when your stomach was its original size. That reduces the amount of food you eat. Fewer calories are taken in, and because part of the intestine is bypassed, fewer calories are absorbed.
