Hi all. I started college this September and began experiencing some horrible GI symptoms (diarrhea, urgency, accidents, unbelievable bloating and gas). I kind of expected it as whenever I would eat food outside or at a friends house I would experience similar symptoms. I lost about 8lbs in a couple of months (I am very petite, so this is significant). My mother freaked out and took my to a GI, who took blood and some stool. The only pertinent findings were that I tested positive for the ASCA IgG marker (not IgA however), and my ESR was slightly elevated. (He did not test for calprotectin, which I found odd.) I did this testing on break from college, so I had no symptoms at this time. Given the results of the tests, my GI wants to do a colonoscopy to confirm or rule-out his suspicion of Crohn's. I think that's rather invasive for someone so young. Further -- I don't even think I have Crohn's. Given that I am completely symptom free during breaks from college where I am solely eating home cooked food -- I think I am eating something that is triggering all the horrible symptoms. This question is: what am I eating. I've tried the elimination diet, the low-FODMAP diet, and nothing has worked. I am able to handle FODMAPs just fine. I am really struggling here, and the symptoms are so embarrassing in college. Any advice would be helpful. I would especially appreciate if anyone could tell me if my experience/symptoms are in line with Crohn's.
