Has anyone else found that foods high in fibre are a major cause of their IBS? If I eat any grain (apart from rice), bananas, wholewheat bread, in fact anything wholewheat, within a few minutes I get a major headache and shortly after major bloating and pain in my stomach. It sometimes feels like I have swallowed a handful of needles. My bowels get clogged up and although I feel like I need to go to the loo, I can't. Dairy is also a major problem, I can consume small amounts of semi skimmed milk, but anything more and I feel awful. I seem to react in different degrees to a lot of foods. What concerns me is that I migrate towards a really unhealthy diet full of white carbs and sugar. If I eat unhealthily I get no IBS symptoms at all. I worry for my long term health eating this way, but the discomfort of adding in healthy foods really puts me off eating them.
