My mum is 54 and occationally after a night in the pub and a short walk home she suffers with fecal incontinence. It only happen when she's had a few drinks and then walks home. She doesnt need to have a bowel movement before leaving the pub but after walking less than half a mile home she's urgently has to go and can not even make it the last few yards home. she has had this problem for many years and gets really upset and embarresed about it. should she see a doctor? she has no other related problems.
