When I got my gallbladder out, I had a 4cm stone and it was about to rupture. After having it out, I had indigestion for about 3 weeks, and then after that nothing, I can eat whatever I want. If you were to get diarrhea after surgery, there are ways to treat it, like taking a bile salts supplement or just eating less fat in your diet.

Please don't leave yourself in pain because you are afraid of the side effects. I know it's scary, but there are ways around it if it does happen. I know when I had gallbladder attacks, they were comparable in pain to when I was in labor. You shouldn't have to endure that.
