The Gastric Bypass surgery makes you eat less food as well as absorb fewer calories, especially early after the surgery. The operation divides the stomach into two uneven parts, one small pouch that sees food and the other remainder or remnant of stomach does not. In order for the food to drain out of the pouch, small intestine is “hooked up” to the pouch (aka gastrojejunostomy). This small intestine is called the Roux limb. This Roux limb is measured for a certain length, 150cm. At this point, the intestine is re-attached to complete the circuit (aka enteroenterostomy). In general, the operation is performed with small incisions known as laparoscopy. Occasionally, the gastric bypass has to be done with a large incision, known as open gastric bypass.
The gastric bypass operation is still the most common weight loss procedure in the United States. Risks of this procedure can include bleeding, infection, leak and blood clots to name a few of the complications. Occasionally, reoperation or additional procedures are required after the bypass to manage complications. In the long-term, operations may be necessary to evaluate for bowel obstruction.
On average, at five years, this operation helps you to lose about 60% of your excess weight. Excess weight is the weight above the weight you should be (ideal weight). Health problems such as diabetes, high blood pressure, sleep apnea, joint pain all can improve or resolve depending on your individual history. Lifelong follow-up with
the surgeon and dietitian are crucial for ongoing success. The weight loss journey is not just about the weight loss; the maintenance, and lifestyle change are major parts of the journey as well.
