Gastric bypass (Roux-en-Y Gastric Bypass) is regarded internationally as the “gold standard” of weight loss surgery designed to reduce your food intake if you have tried and failed to lose weight through diet and exercise. Follow up to 15 years after surgery has shown patients maintain weight loss after gastric bypass surgery.
Gastric bypass can greatly improve the quality of life not only because of an improvement in appearance and an increase in mobility, but also because it can reduce the number and severity of health problems that overweight people are prone to suffer, such as diabetes and heart problems.
Gastric bypass is performed laparoscopically, meaning that the surgeon makes small incisions as opposed to one large incision.
A small stomach pouch is created, restricting the amount of food that can be eaten initially, but long term, the operation also works by switching off the desire to eat. The stomach and about one meter of the small intestine are bypassed. This restricts food intake and stimulates hormones in the gut that suppress hunger and improve diabetes if present.
This type of bypass operation has proven to be an effective, consistent way of losing weight and keeping it off, but to achieve these results it requires lifelong changes to lifestyle and eating.
