Some patients regain weight. Others are unable to adjust their eating habits and fail to lose the desired weight.
An adjustable gastric band is an inflatable silicone prosthetic device that is placed around the top portion of the stomach. This procedure can be performed as a revision procedure for many patients who have had a previous stomach stapling, gastroplasty procedure, or Roux-en-Y gastric bypass surgery but have regained weight.
The procedure is irreversible, [4] though in some uncommon cases, patients can regain the lost weight, via resumption of poor dietary habits, or dilation of the stomach over time, which can require gastric sleeve revision surgery to either repair the sleeve or convert it to another type of weight loss method that may produce better results ...
