The adjustable gastric bands have the advantage of being the lowest risk, least invasive and most easily reversible bariatric surgical operation. They are restrictive in nature due to the ability to adjust the degree of restriction through a simple procedure.
The procedure involves placing an adjustable band around the upper part of the stomach. (The band is filled by adding saline fluid through a port that lies under the skin of the abdomen.) These anatomical changes function to provide a sensation of fullness after a very small meal and reduce hunger between meals.
The disadvantages include an overall expected weight loss that is less than other weight loss surgical procedures. On average, patients may expect to lose 40% of their excess weight. However, if the patient is particularly compliant, they can expect much better weight loss.
