Gastric Bypass Surgery

Gastric bypass surgery is a treatment that aims to shorten the pathway that the food takes in the body. It reduces the stomach volume and shortens the absorption path of the food.


How is gastric bypass surgery done?

In this laparoscopic surgery small incisions are made in the abdomen to allow surgical instruments to be inserted. The stomach volume is reduced to approximately 20-40 cc. The small intestine is attached to the reduced stomach pouch. Thus, the amount of food that the patient can eat decreases and the absorption path is shortened.

Since most of the stomach, duodenum (first part of the small intestine) and the middle part of the small intestine (jejunum) are bypassed, the absorption of digestive foods (especially high-calorie sugary foods) is prevented.

Formerly called roux-en-Y, gastric bypass bariatric surgery is the most commonly performed bariatric procedure. The most important benefit of gastric bypass surgery, besides successful weight loss, is its ability to improve and often eliminate the medical diseases associated with obesity in more than 90%.

Diabetes, hypertension, as well as other medical problems are cured in a large majority of patients. Gastric bypass is both a restrictive and a malabsorptive procedure. The restrictive part of the procedure is the creation of the small stomach pouch with a small outlet. The malabsorptive part of the procedure involves cutting and then re-arranging the proximal small intestine.
