Gastric band. Gastric bands are used in the treatment of obesity. They are surgically placed around the stomach and then tightened. This makes the stomach smaller, leading to the patient's hunger being satiated sooner and consequently to them eating less. With severely obese patients such treatment can be lifesaving and is far more effective than dieting.
