In consultation with each patient, Scripps surgeons will recommend an appropriate weight loss surgery based upon many considerations, like body shape, weight, medical condition and prior surgeries.

Widely accepted as the most effective weight loss surgery available and considered by many as the “gold standard” to alleviate severe obesity, Roux-en-Y divided gastric bypass surgery can be performed as a traditional open or closed (laparoscopic) procedure.

Open surgery requires one long incision, while laparoscopy surgery uses only a few small incisions in the abdominal wall to complete the procedure.

During gastric bypass surgery, the stomach is divided into two sections. One section is a new, smaller pouch that acts as the new stomach and has a capacity of roughly two ounces, as opposed to its former size of about two quarts. The drastic reduction of stomach capacity creates a feeling of fullness after the patient eats only a small amount. As a result, significantly less food is consumed, which forms the basis of results.

A positive surgical outcome means achieving a weight that is within 50 pounds of your ideal body weight. For patients who follow prescribed diet and exercise programs, this goal can be reached as quickly as 12 months after gastric bypass surgery.
