Gastric bypass surgery, also known as Roux-en-Y Gastric Bypass Surgery (RYGB), is the “gold standard” for weight loss surgery.Obese patients with obesity or obese patients who have serious medical conditions that will improve with weight loss (for example, type 2 diabetes or high blood pressure) are potential candidates.

During gastric bypass surgery, a small pouch is made from the patient’s stomach. The new stomach is then connected to the lower part of the small intestine. Patients lose weight because their stomachs can hold only small amounts of food. They lose weight because they absorb fewer calories because the food bypasses the upper part of the small intestine.
