Adjustable Gastric Banding Procedure

Gastric banding is the second most common weight loss surgery performed by the Duke Center for Metabolic and Weight Loss Surgery.

This surgery has a similar goal to Roux-en-Y gastric bypass, in that it makes the stomach smaller to reduce the amount of food you take in and to help your brain generate a feeling of fullness after eating small portions of food.

But, instead of reducing the size of your stomach, the procedure does its job by suturing an adjustable band around the top portion of the stomach. The band can be adjusted with a specialized needle -- usually in a clinic visit -- so you can have it loosened or tightened as needed to reach your weight loss goals.

Gastric banding is considered the least invasive method of weight loss surgery. The procedure can easily be reversed if necessary.

Adjustable Gastric Band

Expected Weight Loss

Results of the adjustable gastric banding procedure have been encouraging, however weight loss is less than for the Roux-en-Y gastric bypass and management requires more frequent clinic visits to adjust how the band narrows the stomach.

Most patients will lose between 80 and 100 pounds. The exact amount of weight you lose will depend on your compliance with the dietary instructions and your tolerance to adjustments to the tightness of the band.

Weight loss is slower with this procedure with most of the weight loss occurring after the first three months. You will need to watch your diet very carefully as the band is adjusted and continue long-term follow up to maintain weight loss.
