Hay, I have been suffering from IBS-D for about 2 and a half years now (I'm nearly 21) and still discovering trigger foods. My IBS bouts are intermittent, usually about 30 minutes after I have eaten a trigger food, but very severe and always result in me passing out on the bathroom floor with severe abdominal pain. I was wondering whether any other people have similar episodes and how long it took them to form a definite list of foods to avoid or whether that is even possible? Also is there any medication that could help with this kind of IBS, as my GP is rather unhelpful? My IBS is really problematic and just as I think I know which foods to avoid another makes me ill and I feel like it controls my life far too much. Any help and/or advice would be really appreciated.
