Hi,I've been thinking about this for some time and with all the different ways people's IBS begins combined with all the different ways people treat their IBS, it seems that their should be about 10 etc. subdivisions of IBS. I recently found my symptoms are the same as >1% within the US but about 10% as others with IBS in Scandinavia. I wonder if this is because I come from a Scandia background. Or since this all began for me after I got giardia in Russia and more people in Scandia go to Russia too. Anyways there must be some reason all our symptoms/treatments are so different. I suspect eventually IBS will get greater divisions than the C, D, or A. I also believe that eventually they will find a biological reason for this problem. I just wish it's soon!LouLou
