Hi there! I'm from the UK as well (i live in Bristol). I have IBS C but my doctor did the same tests on me and diagnosed me with IBS. I think our doctors act much differently to those in the US. My doctor did refer me to an allergy dietitian who's put me on a wheat free diet. It is helping a little but i think i'm going to combine it with Heather's diet because i think i'll need the combination. HOw are you getting on with yours?
