Roux-en-Y Gastric Bypass is a bariatric surgical procedure. The bariatric surgeons highly recommend this method in light of its positive effects. The excessive weight loss after this surgery is higher in a compliant person than with restrictive procedures. The Roux-en-Y gastric bypass is considered as the gold standard of all bariatric surgeries. This is due to the dual benefits of restriction and malabsorptive components of the procedure. Dietary restrictions are significant because the procedure leaves only about 20 mL of gastric pouch in volume. The outlet is so small that a sensation of satiety is created upon distention of food. Intentional malabsorption is created due to the separation of food. This food passes from the biliopancreatic secretions and through the alimentary limb of Y.
