Once the most popular weight loss surgical option, the Roux-en-Y gastric bypass (RYGB) has been performed for over 50 years. After RYGB, a typical patient may expect to lose about 75% of their excess weight and improve their health dramatically. A patient’s appetite is severely depressed after RYGB, which can help patients make the necessary healthy dietary changes needed to be successful. Roux-en-Y Gastric Bypass surgery is designed to help reduce the amount of food you eat by decreasing hunger and overall calorie absorption from fat. In addition to significant weight loss, RYGB dramatically reduces the health risks posed by obesity-related health conditions, including diabetes, sleep apnea, hypertension, and many others. Our experienced bariatric surgeons, Dr. Stephen Boyce and Dr. K. Robert Williams, can help many patients achieve their goals with advanced Gastric Bypass surgery and a thorough aftercare program designed to guide individuals through a safe, effective weight loss.
Gastric Bypass surgery is a metabolic operation. This means that the operation alters the patient’s physiological response to fat loss. When dieting, the brain senses the loss of body fat and it decreases your metabolism so you burn fewer calories. The brain also causes your appetite to increase and make you feel less full when eating. The end result is weight regain! Luckily, after RYGB, the exact opposite occurs. In the face of body fat loss, appetite is suppressed, patients feel full more quickly, and their metabolism remains high, burning more calories. This allows the patient to lose significant weight and reach a new lower metabolic set point. After RYGB, the patient routinely is able to be free of serious health problems like diabetes, hypertension, and sleep apnea. The procedure is performed laparoscopically, a method which involves small incisions and surgical instruments to make the surgery less invasive and the recovery less lengthy and uncomfortable.
The Gastric Bypass procedure involves dividing the stomach to create a small pouch out of the very top part of the stomach. This smaller stomach pouch then directs the food you eat directly into the small intestine, ultimately bypassing 95% of the stomach. It also bypasses about 10-15% of the small intestine, where nutrients and calories are absorbed. The malabsorption created by the RYGB is primarily for fat and vitamins and minerals. Carbohydrates and protein are absorbed fairly normally.
Our weight loss surgeons will talk more with you about the risks of Gastric Bypass surgery during your initial consultation. We do everything possible to minimize risks and potential complications associated with this procedure, and we offer a comprehensive aftercare program to help ensure your safety during the weight loss process. If your doctor determines that Gastric Bypass surgery is not the ideal procedure for your unique needs, he can suggest alternative weight loss treatments that can help you attain similar results.
The operation is performed laparoscopically 99.9% of the time at the New Life Center for Bariatric Surgery. Laparoscopic surgery involves using a small camera and light source to see inside the abdomen while the operation is performed through six small (1/4-1/2 inch incisions). A 20 cc stomach pouch is created and the small intestine is re-routed to bypass about 10-15% of the bowel. Doing so allows the patient to be satisfied with smaller food portions and also prevents efficient calorie absorption, promoting amazing weight loss. Small incisions speed recovery because of less pain, fewer pulmonary complications, and fewer infections and less muscle-mass loss.
Gastric Bypass surgery typically requires a one to two-night hospital stay. Oral pain medication is often all that’s necessary to control pain. Light activities, such as walking and stretching, are usually advised to help patients progress gradually throughout the recovery process. Most individuals who have sedentary jobs can resume working in about two weeks. Resumption of formal exercise and unrestricted activity can often begin at about one month post-surgery.
Long-term success is dependent on aftercare following a safe operation. Our experienced multidisciplinary team is there to assist you every step of the way!

“I have been fishing and hunting. My life has really changed for the better, thanks for all you do! I went on our vacation up north in an area called ‘The Boundary Waters,’ the area between Canada and MN. I caught the big fish – a northern pike – there a couple of weeks ago. I had a chance to go pheasant hunting in South Dakota and would have never have done these things prior to surgery.”
