Roux-en-Y Gastric Bypass also known as Gastric Bypass surgery is the most common form of weight loss surgery. Roux-en Y Gastric bypass is still considered the gold standard of weight loss surgeries. It is performed via a laparoscope and includes creation of a small gastric pouch of only 15-20 ml. The procedure involves approximately 5 small incisions and takes about 1 ½ hours. It bypasses the upper part of the intestine the duodenum, by rerouting the intestine through a connection called a Roux intestinal limb. There are multiple mechanisms of weight loss for this bypass. They include decreasing calorie intake through a smaller stomach, hormonal by increasing your metabolism, and lastly by decreasing the amount of calories you absorb. Expected weight loss averages around 75% excess weight loss over 2 years with the average of 60% excess weight loss over 10 years. The Roux-en-Y gastric bypass is the most studied operation with multiple studies showing the improvement in weight related health conditions as shown below.
