Diarrhea from contrast dye?

I had a CT scan two days ago and since then I've have diarrhea and awful gas (I didn't have anything wrong bowel-wise before I go the the doc, except pain in my low right tummy.) I called the hospital, they simply told me it was because of the contrast dye that they engender you drink. I was wondering if anybody out there know how long this lasts, because it's getting a little ridiculous.
Answers:    Your sensitivity to the contrast is fairly normal. It is hurtful stuff. Force fluids to try to flush it out of your body. I had a ton of contrast when I was contained by the hospital and had constant diarrhea. Of course, I can get diarrhea from a chalice of water. Good luck.
