If you have read my posting below you'll know i've suffered chronic D and weight loss for 3 years.I have been investigated for .....IBD, pancreatitis, coeliacs, standard stool MC+S investigation (infection screen), i've had small bowel x-rays, large bowel x-rays, biopsies, numerous blood tests (slightly abnormal LFT's but nil else). I am cutting out as much milk as possible and i have previously been on a wheat free diet with no improvement. What else might cause chronic D? i 'd be grateful to know whether others with suspected IBS have been investigated for anything other than the above.I suppose i am clutching at straws, i cant beleive i have IBS because my syptoms are so severe and every day i struggle, it is worse when i'm stressed but even when i am not i still have to take 10 imodium every day. I have also tried colofac (Mebeverine )which helped a little but the effects seemed to wear off, and i have had a little sucess with cholecystamine (bile salt binder) but nothing works consistently.Anybody suggest any tests i should ask for next? I am sure i have something wrong with my small bowele to account for my weight loss but i'm not sure what!
