I had my gallbladder removed April 2005, I too have had constant diarehea, also problems with weight gain. I started working out in January and started watching what I ate and to this day I have not lost any weight. I am very discouraged and have stopped going to the gym. Now I am having problems with constipation. So I don’t know what is going on with my body. All I know that this is all occured since I had the surgery.
