I have IBS-D that has just flared up again recently. I had no problem with it for several years and due to a high stress situation lately, it has reared it's ugly head again. I've been able to tame it a bit with fiber, so that is a relief, however it does not get rid of the horrible cramps and urgency to go.Anyways, I've noticed with this flare up that red food dyes don't seem to be "processing" right. I had some fruit flavored drink last night and cherry pie and noticed that I had red stool this morning. I panicked at first thinking it was blood, but am not so sure it is. Does anyone else have this problem? Or do you feel I should have this checked out?
