Yes another poop topic! 
So i'm doing pretty good for someone who's had CD for many many years and taking only Pentasa.
My only symptom is diarrhea. No cramps, blood in bm, no anemia or excessive tiredness. None of that. Except for diarrhea since my small bowel resection.
Some days are better than others. Sometimes I only go once a day, sometimes 2-3. I usually take immodium by the third bm.
I tried figuring out what makes my D worse. I pretty much eat anything. Even fast food. I did notice that after eating fast food I'd need to rush to the washroom. But sometimes I didn't. So I thought it can't be fast food if it happens only sometimes. Then I thought, maybe it's the raw vegetables. Like green salads or tomatoes. But same thing again. Then I thought maybe it's the excessive salty potatoe chips that I indulge in at times. Same thing. Then I thought maybe it's the black carbon particles in my Britta water filter. But nope.
And I finally figured it out!
It's the Christy's Chocolate Chips Ahoy cookies which I have been eating my whole life. I eat two of those everyday! And one day I noticed if I skipped them for a few days, my bms were better. Usually once a day, and more formed also. So now I try to eat them only twice a week as opposed to everyday.
So now I ask you guys, what makes you poop? Have you figured it out? Maybe it's only one type of food that you have not figured out yet.
