I am 79 yrs old and I was diagnosed at 76 yrs. after loosing 35 lbs and having c-diff. I still have diarrhea. Nothing that I have found 'fixes' it. I can go out by taking a medication that I received from my Gastro dr. That will last for the afternoon until about 6 or 7 pm, then I need two more of these tiny little pills or be at home. As for the depression...
