Adjustable gastric banding, or Lap band surgery, is a form of restrictive weight loss surgery (bariatrics) designed for obesity patients with a body mass index (BMI) of 40 or greater - or between 35 – 40 with those who have comorbidities that are known to improve with weight loss. The gastric band is an inflatable silicone prosthetic device which is placed around the top portion of the stomach via keyhole laparoscopic surgery.
