Gastric Bypass (Roux-en-Y)

The Roux-en-Y gastric bypass is the most frequently performed weight loss procedure in the United States. In this procedure, the surgeon creates a small stomach pouch, about the size of a large egg. The pouch is created by dividing the small intestine just beyond the first 50cm of small intestine, also called the duodenum, for the purpose of pulling it up and attaching it with the newly formed stomach pouch. The other end of the small intestine is connected into the side of the Roux limb (the portion of the small intestine attached to the new small stomach) creating the "Y" shape that gives the technique its name. In this type of surgery, the patient's stomach is divided into two pouches. The upper, smaller pouch can hold only about one ounce of food. The lower portion of the stomach and upper part of the small intestine are bypassed, meaning that food spends less time in the digestive system and the body absorbs less fat and calories from the food. Significant changes to diet and lifestyle are needed to ensure patient safety and success. Eating more food than the smaller stomach can handle, or eating foods high in fat or sugar, can cause vomiting, which stresses the stomach. To lose weight after bariatric surgery you must continue following the diet and exercise guidelines given to you by the doctor.

We require follow up visits to monitor your progress and evaluate your health after surgery. Patients who follow their doctor's guidelines typically lose 50% of their excess weight in the first two years following surgery.
