Gastric bands: How it works, surgery, who should have it
Gastric banding is a surgical treatment.These kinds of intervention are known as surgery.A person feels full after eating less food because of the procedure.
The American Society for Metabolic and Bariatric Surgery estimates that 216,000 surgeries were performed in the U.S. in 20163.4 percent were gastric bands.The most common type was gastric sleeve surgery.
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.
The band is placed around the upper portion of the stomach by the surgeon.The tube can be found under the skin of the abdomen.
The degree of constriction around the stomach can be adjusted.A small stomach pouch is created by the band above the rest of the stomach.
The amount of food that the stomach can hold is reduced by having a smaller stomach pouch.After eating a smaller amount of food, the feeling of being full is increased.This reduces hunger and lowers food intake.
The advantage of this form of procedure is that it allows the body to digest as usual.
A band is put on.It is done in an outpatient clinic, and the individual usually goes later the same day.
The procedure is painless.It is done through the skin.Between one and five small surgical cuts are made in the abdomen by the surgeon.A laparoscope, a long narrow tube with a camera, is used for surgery.The procedure can take up to 60 minutes.
The patient should not eat after midnight.Most people can resume most normal activities within 2 days, but they may need to take a week's leave from work.
Guidelines used to only recommend placement of the gastric band if the person had a body mass index greater than 35.If there were other problems associated with being obese, some people had surgery.It was because of the high risk.
The safety record of the procedure has improved due to the advances in surgical techniques.
The band can be removed or adjusted.If not enough weight is being lost, or there is vomiting after eating, adjustedability means it can be loosened.
Between 40 and 60 percent of excess weight can be lost, but this depends on the individual.
Eating too much can lead to vomiting, and the individual needs to follow the recommended diet.
If a person undergoes the procedure in order to lose weight, they may be disappointed.
The stomach is stapled to make it smaller and then attached to the small intestine.This reduces food intake.
It changes the gut hormones and reduces the absorption of vitamins.It is difficult to reverse.
A sleeve gastrectomy involves removing a large portion of the stomach and leaving a tube or banana-shaped sleeve.It can disrupt metabolism by reducing the amount of food needed to feel full.It is not permanent.

Duodenal switch surgery involves two procedures.The surgeon places the food in the small intestine.Most of the small intestine is bypassed by the food.Weight loss is more rapid, but the risks are greater.
