Obesity Surgery

Gastric Bypass

Gastric bypass is a type of weight loss surgery used for the treatment of obesity. It is a combination of both restriction and mal absorption. The procedure is performed to restrict food intake and reduce calorie and nutrient absorption.

In gastric bypass surgery, a small stomach pouch is created by stapling along the upper part of the stomach. Next the small intestine is cut two sections. The lower section of the small intestine is attached to the opening in the stomach pouch. This pouch enables food to bypass the lower stomach and portion of the small intestine. The pouch can hold only a few ounces of food at a time and by bypassing the small intestine and the stomach, fewer calories and nutrients from the food are absorbed. As a result the patients consume less food, absorb fewer calories and achieve weight loss.

Roux-en-Y gastric bypass procedure can be performed laparoscopically (using tools inserted through small incisions) or through a larger open incision (an open procedure). Your obesity surgeon will decide which surgery is best for you.

In addition to quick and dramatic weight loss, gastric bypass surgery could also improve health issues associated with severe obesity.
