At Carilion Roanoke Memorial Hospital, which has been designated as a Bariatric Surgery Center of Excellence by the Surgical Review Corporation, we offer Roux-en-Y gastric bypass surgery.
A gastric bypass or RYPGB is performed as an open operation or minimally invasive laparoscopic surgery under general anesthesia. In the procedure, your surgeon creates a small pouch out of a portion of your stomach reducing it from the size of a grapefruit to the size of a baseball and attaches it directly to your small intestine. A gastric bypass limits the calories you can take in each day to less than 1,000 and causes food to bypass a large part of your stomach and small intestine, which substantially reduces fat and calorie absorption.
Possible risks of gastric bypass include dumping syndrome (when you eat high-fat foods, you may experience vomiting, nausea, weakness, fainting and diarrhea), ulcers, leaks from staple lines and increased gas. Anesthesia risks are allergic reactions to the medicine used and breathing problems. Risks for any surgery are blood clots, blood loss and infection.
