I'm kind of at a loss for what's triggering my IBS. I have thought that maybe dairy was triggering it, but I'm not for sure, since my symptoms appear hours later or the next day after eating something. When I was an infant, I was VERY colicky - I wouldn't take the regular baby formula well at all. My mom noted that she could actually SEE the gas moving around in my abdomen. I cried a lot and was very fussy (I probably didn't feel good!!). When my mother switched me to soy formula, my problems stopped. Fast forward to around my sophomore-junior year of high school. My true IBS symptoms seemed to slowly arise after a really bad bout of influenza and double sinus infections. My mom also has minor IBS, but until then, I had very few problems with the things I ate. I have been on Paxil (quit from side effects) and am on Prozac to help me deal with my correlating anxiety disorders. But even when my anxiety is pretty under control, and I am in a good mood, I still get IBS symptoms. And I keep thinking its food related, as it was when I was a baby. I don't think I am allergic to casein protein in milk, because those have somewhat different symptoms than what I'm seeing. And I had an endoscopy done a few years back to see if I had Celiac disease, and I didn't. I don't know what to do. I think I will try to do the lactose intolerance breath test. The problem is, the symptoms are either IBS or lactose intolerance or both together, because they are the same! I have diarrhea sometimes, loose stools (but not diarrhea), gas, cramps, and very occasional nausea (but I think the nausea is anxiety-induced). I'm so sick of this. I am 21 now and trying to go to college. Does anyone have this problem as well?
