I'm a fellow sufferer of IBS too. Though I have tried cutting out foods and can't find one that upsets me particularly. I have IBS C and I do think I don't drink enough which may be a cause. But it runs in my family (down my fathers side).

For me the doctors have told me mine is caused mainly by anxiety and stress. I might be a little intolerant to food but the fact that I can't pinpoint it means they don't think that is the case. Have you ever heard of the brain/gut connection? Basically your gut is your second brain and will tell you if there is anything wrong. I get acid reflux and my IBS flares whenever I am very anxious and stress. The symptoms then make me anxious and stressed and then I get more symptoms. Nice circle that!

I have just had to learn to deal with it. I do get periods where I struggle to cope (just coming out the other side of one of those periods) but sadly I think it is something I am going to have to accept. As MDGirl says there are plenty of ways to manage it (both in the US and UK). I always have buscopan, Imodium, pepto and gaviscon in my handbag. I used to carry motilium as well but that has been banned in the UK.

I'm not saying yours isn't caused by food intolerances. I think that is the case for a lot of people with IBS, just that mine seems to have no relation to food except that onions and garlic give me acid reflux!
