Hi Gingi, I don't know if this will make you feel any better but I am pre-surgery and have actually been through the same thing. The Drs originally blamed reflux for my problems but soon discovered it was my gallbladder. Although a fast weight can lead to gallbladder issues I bet your health issues will get a lot better when they remove your gallbladder and I don't think you should feel it is necessarily related to your surgery. Good for you for being down 80 lbs!!!!!
