I had my gallbladder removed almost 11 years ago and since them I have had extremely bad diarrhea, stomach pain, gas and bloating. I have been to my doctor and have been tested for celiac disease and have tried a dairy free diet for about a week and neither were the problem. I had a colonoscopy done and that was clean as well. I am lost and don't know what else to do. I always thought it was due to greasy foods but even just a simple subway sandwich does it too. So really if I watch what I eat and cut the grease I still experience the same symptoms. Don't know what to do!
