Adjustable gastric band
A laparoscopic adjustable gastric band, commonly called a lap-band, A band, or LAGB, is an inflatable silicone device placed around the top portion of the stomach to treat obesity, intended to slow consumption of food and thus reduce the amount of food consumed.Adjustable gastric band surgery is an example of bariatric surgery designed for obese patients with a body mass index (BMI) of 40 or greater — or between 35 and 40 in cases of patients with certain comorbidities that are known to improve with weight loss, such as sleep apnea, diabetes, osteoarthritis, GERD, Hypertension (high blood pressure), or metabolic syndrome, among others.In February 2011, the United States Food and Drug Administration (FDA) expanded approval of adjustable gastric bands to patients with a BMI between 30 to 40 and one weight-related medical condition, such as diabetes or high blood pressure. However, an adjustable gastric band may be used only after other methods such as diet and exercise have been tried.
