My sister, her husband and a ex girlfriend all three had it done.

Everyone one of them has problems. Everyone has gained the weight back.
There is a place in Indiana that does nothing be treat people with bypass problems.

Why? Because like I told my sister, you have an eating disorder. You need to fix why you eat that way, not the result of it. They all three lost a lot of weight and followed the diet for a while. But old habits and emotional feeding started again when they stopped hurting from the surgery. My brother in law has another problem with tearing in the belly. They all started slowly over eating and and eating the wrong foods and just like before started gaining it back.
