You might be a good candidate for a gastric re-sleeve if you have the following 2 symptoms which indicate dilation of your stomach: 1) increase in the food intake, and 2) regaining weight.
The surgeon will perform a swallow test or endoscopy to determine if your stomach is in fact dilated. If yes, he may recommend a gastric a re-sleeve.
If the stomach is not dilated maybe you need a malababsortion procedure like gastric bypass or mini-gastric bypass.
