Gastric bypass surgery is a treatment for morbid obesity. It is performed laparoscopically (using small incisions) by inserting small, specialized instruments into the abdomen. The surgery creates a small upper stomach pouch. Food passes from the esophagus into this small pouch before it enters the intestine through a small opening, bypassing the rest of the stomach and part of the small intestine. Food does not mix with digestive enzymes until it has traveled 4 - 6 feet into the intestine. Doing the surgery laparoscopically reduces pain, supports a quicker recovery, and allows for a shorter hospital stay. Many patients are released from the hospital one or two days following surgery and can return to work as early as two weeks postoperatively. Patients must follow a recovery diet and follow-up guidelines to help minimize the risk of complications and better the chances of weight loss. Typically, gastric bypass patients loose between 60-80% of excess weight and have about an 80% chance of keeping the weight off. The weight loss can also have a positive impact on hypertension, diabetes, sleep apnea, and arthritis. Weight loss surgery is not a cure for obesity. Patients must be willing to commit to a lifestyle change of healthy diet, exercise, and follow-up appointments to help realize their goal of weight loss.
