I am part of the Fibro and CD Club. I do see more symptoms when stressed but I bet Doctors would argue that Stress does not make CD worse. I do not have IBS though.
I have noticed over the years if I have an argument with DH then I have to run to the potty the stress makes me have diarrhea. Also a terrible boss I had recently make my CD flare when she yelled. My stomach would ache etc...
