The Gastric Bypass is the most popular weight loss surgical procedure worldwide. It provides for excellent weight loss of about 75% excess weight for the average patient. Its success is derived from decreasing the amount of food the patient can eat, decreasing hunger and decreasing calorie absorption. The benefit of this dramatic weight loss includes resolution/improvement in all obesity related conditions (diabetes, hypertension, sleep apnea etc.).
In recent years, better clinical understanding of procedures combining restrictive and malabsorptive approaches has increased the choices of effective weight loss surgery for thousands of patients. By adding malabsorption, food is delayed in mixing with bile and pancreatic juices that aid in the absorption of nutrients. The result is an early sense of fullness, combined with a sense of satisfaction that reduces the desire to eat.
According to the American Society for Bariatric Surgery and the National Institutes of Health, Roux-en-Y gastric bypass is the current gold standard procedure for weight loss surgery. It is one of the most frequently performed weight loss procedures in the United States. In this procedure, the gastric bypass surgeon uses stapling to create a small (15 to 20cc) stomach pouch. The remainder of the stomach is not removed, but is completely divided from the stomach pouch. The outlet from this newly formed pouch empties directly into the lower portion of the jejunum, thus bypassing calorie absorption. This is done by dividing the small intestine just beyond the duodenum for the purpose of bringing it up and constructing a connection with the newly formed stomach pouch. The other end is connected into the side of the Roux limb of the intestine creating the “Y” shape that gives the technique its name. The length of either segment of the intestine can be increased to produce lower or higher levels of malabsorption.
The operation is performed laparoscopically 99.9% of the time at the New Life Center for Baritatric Surgery. Laparoscopic surgery involves using a small camera and light source to see inside the abdomen while the operation is performed thru six small (1/4-1/2 inch incisions). A 20 Ml stomach pouch is created and the small intestine is re-routed to bypass about 25% of the bowel. Doing so allows 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.
Patients generally can expect to spend two nights in the hospital. Pain is usually well controlled requiring only oral pain medication to do so. Activity is progressed slowly starting with light activities such as walking and stretching. Patients with sedentary jobs may return to work in about two weeks. Unrestricted activity begins at one month with the resumption of formal exercise. Expected excess weight loss is about 75% for the average patient.

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.
