hi,*for me*, stress or anxiety is what causes my IBS (once it goes away, symptoms fade). HOWEVER, certain foods do indeed make my symptoms worse (dairy products, greasy/carby fast food, beans, etc). For example for the past two weeks I wasn't able to eat out at restaurants because the ibs was really bad (it was finals season). basically all i could eat was tofu, soup, veggie burgers, fruit and sugar-free jell-o. it was okay at first, but after a while i was feeling ready to retch from the lack of variety.
So i definitely share your frustration with this thing, I KNOW how ANNOYING it is not being able to eat stuff you like, especially if you've *never* had problems w/ that food before. I know it doesn't make ANY sense, and what's worse is that because of that, other people just assume i have psycho eating habits, when i turn down offers to go out for sundaes or cake. You don't know how many friends always kept insisting that i was probably just "lactose intolerant" and i should try Lactaid.
ARGH Or people assummed i was on a low-fat diet and I was trying to starve myself. ARGGHH! They don't know that about a year and a half ago, i lived off of whole-milk yogurt, cottage cheese, mozzarella string cheese, steaks, macadamia nuts, and chicken salads w/ guacamole and extra sour cream. i poured heavy cream into my hot chocolate. on occasion i would eat 1/2 pints of ice cream, and no gas, pain, no D or C! But then when exam time comes, or when i have other stressful issues to deal with (new job, moving to the other coast, starting graduate school, etc) my digestive system GIVES UP on me and so i have to watch what i eat VERY CAREFULLY. Sometimes i get really bad gas/pain from eating ANYTHING, and so i have to fast for half a day or something.i think the worst part about this whole IBS thing is that it doesn't make ANY physical sense! (to me, at least). i don't get how on Monday i can eat one thing and get major gas, pain, D, etc, but on Friday i can eat the EXACTLY THE SAME THING and have no issues.
I tell you, my digestive system has a mind of its own
