Gastric banding is a surgical procedure for the treatment of obesity. This is a type of weight loss surgery. It works by contracting the stomach, making a person feel full after eating less food than usual.
The American Society for Metabolic and Bariatric Surgery (ASMBS) estimated that approximately 216,000 bariatric surgeries were performed in the United States in 2016. Of these, 3.4% were related to gastric banding. Sleeve surgery on the stomach was the most common type, accounting for 58.1% of the total number of operations.
Gastric banding is a type of bariatric surgery in which a silicone band is placed over the top of the stomach to reduce the size of the stomach and reduce food intake.
The surgeon puts a bandage on the upper part of the stomach and attaches a tube to the bandage. The tube is accessed through a port under the skin on the abdomen.
Adjustments can change the degree of compression around the stomach. The group forms a small gastric sac above it, with the rest of the stomach underneath.
A smaller stomach reduces the amount of food the stomach can hold at one time. The result is an increased feeling of satiety after eating a small amount of food. In turn, this reduces hunger and helps reduce overall food intake.
The advantage of this type of weight loss surgery is that it allows the body to digest food normally without malabsorption.
Install a gastric band under general anesthesia. This is usually done on an outpatient basis and patients usually come back later in the day.
The procedure is minimally invasive. It is performed through a keyhole incision. The surgeon makes one to five small surgical incisions in the abdomen. The operation is performed using a laparoscope, which is a long thin tube with a camera attached to it. The process usually takes 30 to 60 minutes.
Patients should not eat from midnight on the eve of surgery. Most people can resume normal activities within 2 days, but they may need a week off.
In the past, guidelines have recommended gastric banding only if you have a body mass index (BMI) of 35 or higher. Some people with a BMI of 30–34.9 undergo surgery if they have other obesity-related problems such as diabetes, high blood pressure, or sleep apnea. This is due to the high risk of complications.
However, advances in surgical technology have improved the safety record of the procedure and this recommendation no longer applies.
It is also possible to remove or adjust the strap. Adjustability means that it can be tightened or loosened, for example, if weight loss is not enough or if you vomit after eating.
On average, you can lose from 40% to 60% of excess body weight, but this depends on the individual characteristics of the person.
People need to carefully follow dietary recommendations as overeating can lead to vomiting or dilation of the esophagus.
However, if a person is undergoing surgery hoping to suddenly lose weight, or if weight loss is the main reason they choose surgery, they may be disappointed.
During this procedure, the surgeon stitches the stomach together to make it smaller and connects the stomach directly to the small intestine. This reduces food intake and absorption of calories and other nutrients.
Drawbacks include that it alters gut hormones and reduces nutrient absorption. It’s also hard to turn back.
Sleeve gastrectomy: removal of most of the stomach and leaving a banana-shaped tube or sleeve closed with staples. This reduces the amount of food needed to create a feeling of satiety, but also disrupts metabolism. It’s irreversible.

Duodenal Switch: The operation includes two procedures. First, the surgeon redirects food into the small intestine, as in a sleeve gastrectomy. The food is then redirected to bypass most of the small intestine. Weight loss is faster, but there are higher risks, including problems associated with surgery and nutritional deficiencies.
