I have been chatting to my Mum recently about IBS. She said that most of my family on my Dad's side (including Dad) all have some form of stomach or intestinal problems. Dad has terrible D sometimes after eating and has certain foods he avoids but has never been to the Doctor about it. My Aunties all have a similar thing but all live overseas so I can't talk to them about it (hoping they get online!!!)Can IBS be passed down through generations?
