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). Roux-en-Y is the most common weight loss surgery.
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.
This leads to dramatic and rapid weight loss for almost all patients. Loss of more than 100 lbs. within the first three months is not uncommon. As the body nears a weight that is average for the patient’s gender, height and frame, weight loss slows.
This animation shows the Roux-en-Y procedure performed using minimally invasive laparoscopic techniques. The procedure is the same for all patients whose health qualifies them for minimally invasive surgery.
Four small incisions, each the diameter of a pencil eraser, present fewer healing complications than the traditional surgical procedure’s single long incision.
