Gastroplasty surgery 4 years ago, why am I gaining weight?

Gastroplasty prob. Gastroplasty means a row of staples to make a fixed pouch. Rarely done in us now. Most have problems. Doesn't reduce hunger. Causes blockage of food which is not adjustable. If too tight, people vomit and shift to slider foods. If too loose, people can eat too much. You really need to see your doctor to see if pouch is ok. Also to make changes to your eating behavior.
