Hi, I had pelvic/abdomen ct scan a couple of weeks ago and had the same problem. I felt terrible and had diarrhea all afternoon and night.My tests were ok, and so the dr. thinks I probably have IBS/D. I've been doing ok since the day of the ct scan, though. I can't eat anything with insoluable fiber, going very easy on the fats, no raw vegetables. I take psyllium husk powder twice a day, and my nutritionist told me to take slippery elm bark powder, and that really seems to be helping me a lot, along with aloe vera juice. I haven't had any problems since the day of the ct scan.I'm new on the board, and I appreciate all the information that's been given here, some of it very helpful.
