Gastric banding is a surgical treatment for obesity. These kinds of intervention are known as bariatric surgery. The procedure constricts the stomach, so that a person feels full after eating less food than usual.

How it’s Done 

Gastric banding is a type of weight loss surgery that involves placing a silicone band around the upper part of the stomach to decrease stomach size and reduce food intake.

It is approved for useTrusted Source as a weight loss treatment by the Food and Drug Administration (FDA).

The surgeon places the band around the upper portion of the stomach and attaches a tube to the band. The tube is accessible through a port under the skin of the abdomen.

Using this port, the surgeon injects saline solution into the band to inflate it.

Adjustments can alter the degree of constriction around the stomach. The band creates a small stomach pouch above it, with the rest of the stomach below.

Having a smaller stomach pouch reduces the amount of food that the stomach can hold at any one time. The result is an increased feeling of fullness after eating a smaller amount of food. This, in turn, reduces hunger and helps lower overall food intake.

An advantage of this form of bariatric procedure is that it allows the body digested as usual, without malabsorption.


There are some risks associated with having a gastric band.

These include the following:

  • Some people have an adverse reaction to anesthesia, including allergic reactions, breathing problems, blood clots in the legs that may travel to the lungs (pulmonary embolism), blood loss, infection, and heart attack or stroke during or after surgery.
  • Weight loss may be slower compared with other types of surgery
  • The band can slip or have mechanical problems, or it may erode into the stomach, requiring removal.
  • The port can shift, making additional surgery necessary. Between 15 and 60 percent of people are reported to need follow-up surgery.

The individual needs to follow dietary recommendations with care, as overeating can lead to vomiting or dilation of the esophagus

As with other types of weight loss surgery, gastric banding also carries these risksTrusted Source:

  • injury during surgery to the stomach, intestines or other abdominal organs
  • hernia
  • inflammation of the stomach lining (gastritis), heartburn, and stomach ulcers
  • wound infection
  • gastrointestinal scarring that can lead to bowel blockage
  • poorer nutrition as a result of the restricted food intake

Weight loss can give some people a boost in confidence, and this can be another benefit.

However, if a person undergoes the procedure in the hope of sudden weight loss, or if weight loss is their main reason for choosing surgery, they may be disappointed.
