I had D for 10 years straight, and, untreated, my system did slowly keep deteriorating. The best suggestion I can give is to keep plugging away at trying to figure out the initial cause, as you may be able to use that to track down something that will really improve your situation. When I was at my worst, at the end of that period, I couldn't control anything, which kept me home until after my lunchtime D, which followed my breakfast D. When I finally found a treatment that got at the cause, I could see the results in frequency and urgency at first, and then in quality of the stools over time. I now realize that I could have made my life a lot easier with OTC meds to give me more control before then; but I would have always had the same fear you talk about. Treating the inflammation that seems to have been at the root of my suffering (and anxiety and despair) has given me constant improvement over 10 great years in a row. I know it is easier to say than to do, and I know that there are numbers of things that can cause this; but it really is worth the effort, especially as this is not impacting your life too greatly at the moment.Mark
