Why is the procedure performed
Weight-loss surgery may be an option if you are very obese and have not been able to lose weight through diet and exercise. Gastric bypass surgery is not a quick fix for obesity; it will drastically change your lifestyle. After this medical weight loss surgery, you must eat healthy foods, control portion sizes of what you eat and exercise. If you do not follow these measures, you may have complications from the surgery and poor weight loss.
Always discuss the benefits and risks of a gastric bypass with your surgeon.
