The Gastric bypass surgery is a type of bariatric, or weight loss, surgery. During gastric bypass surgery, your physician makes changes to your stomach and small intestine to change the way they absorb and digest food. While that may sound appealing, gastric bypass surgery isn’t for everyone. Like any major procedure, it has significant health risks and side effects. In addition, the long-term success of gastric bypass surgery depends on your ability to make permanent changes in your lifestyle. When you want to be considered for gastric bypass surgery, you must undergo a thorough evaluation to determine if it’s suitable for your situation.
If you’ve had gastric bypass surgery, you will have lost about 30% to 40% of excess body weight. With gastric banding surgery, you lose 1 to 2 pounds a week — so by six months, you’ll have lost 25 to 50 pounds.
