Hi. I had the same symptoms and also had my gallbladder removed which the surgeon said it was somewhat inflamed but nothing major. I continued with the diarrhea (all of this for about 5 years). Finally, my daughter told me to be tested for food allergies- and I did. I am allergic to dairy, walnuts, Lobster and Oysters. I have stopped eating these foods (and reading labels very carefully) and my diarrhea has stopped. Most important is to read labels- for example most salad dressings contain milk, some medications contain milk, etc. I hope this helps. I also have other stomach problems but the diarrhea is under control. I know can go out to eat without going to the bathroom at the restaurant- LOL. I Watch for buttery foods as they contain milk. I hope this helps.
