I am very new to IBS and keep thinking that I have something else. About the middle of June I started having D, with "occasional" cramping and it came just out of the blue. My doctor ordered a Barium Enema, had my D tested and also sent me to a specialist for a Colonoscopy. The bottom line was that I had IBS. I'll have to admit that it isn't as bad as it was in the very beginning. What did change in my life was a huge move (that took 3 years!)from Southern California to the Missouri Ozarks. I love it back here but have to admit that the intense humidity we've had this summer has been pretty hard to take. Also, my husband and I are together more back here and that can cause stress. However, we were here for four months in 1998 and even though it was humid and there was some tension, I never got D like I've experienced now.I'm wondering whether anyone would know whether a different climate can cause IBS. Also, I've hardly had any cramping. I do always have the D when I wake up (although I have been having some small really soft stools), usually when I eat something, or sometimes when I feel stressed out. Also, once the D starts, it keeps up for a while.Thanks for any input.
