I wanted to know... what happens after you have gallbladder removal surgery.. My doctor told me i have plyops and i can continue with the pain or have my gallbladder removed.. Being in my hands i want to make sure i know everything about it in order to make the right decision.. i have done most of the research and answered my own questions.. but there is one i still am not sure of.. do people gain weight or loose weight after having their gallblader removed?
