Adjustable Gastric Band

Adjustable gastric band surgery is a laparoscopic procedure that limits food intake with minimum interference to the normal digestive process. The surgeon wraps a silicone band (Lap-Band) around the stomach, forming a small gastric pouch in the upper stomach. The band itself creates a narrowing that connects the upper stomach to the lower stomach.

The band restricts the amount of food you can consume in a single meal. Food passes slowly from the upper stomach to lower stomach, helping you feel fuller longer. The surgeon can easily adjust the band after surgery depending on how much weight you’re losing. 



  • This procedure is the safest form of weight loss surgery and has a rapid recovery time.
  • Patients lose 50 to 65 percent of excess body weight during the first two years.
  • Because the stomach or intestines are not cut, there is no risk of intestinal leak, dumping syndrome or food intolerance.
  • The feeling of hunger is eliminated.
  • Existing obesity related health conditions, such as diabetes, high blood pressure and sleep apnea improve.
  • Surgery takes about one hour and some low BMI patients leave the hospital the same day. Others require only an overnight stay.
  • The band can be tightened or loosened as needed, or removed altogether.


  • You have to re-learn how to eat. Eating too fast or too much can make you vomit.
  • Some foods will not pass through the narrow part of the stomach.
  • Success requires follow-up visits to adjust the band every six to eight weeks.
  • There is a small risk that you’ll need surgery to re-position the band if it slips, or if the tube kinks or twists.
  • This procedure will be ineffective if you eat excess amounts of high-calorie foods such as ice cream and milkshakes.
