Bowel movement question regarding DH
My DH has been recently having (tmi!) frequent, smelly loose bm's for the past week or so. He drinks quite a bit of water, is fit and we eat fairly healthy. He has no idea what has brought this on. I suggested maybe alcohol is to blame??
Any tips on what we can do to solve this problem? What are the best things to eat or take to regulate bowels? I have read soluble fibre, is this true?
TIA :)
ETA: I should add that he has always been a massive dairy person and eats a lot of yoghurt too. So I don't think it is lactose intolerance.
