I've been gaining weight after gastric bypass

Is this normal? The purpose of gastric bypass is exactly the opposite. Why isn't it working? I have not been over-eating (at least I don't think I have). What am I doing wrong? Please help!

That is very strange. I'd go back to your bariatric surgeon to confirm everything is as it should be. 
Sorry your having such a difficult time, good luck.
