Diarrhoea and constipation can be linked.
Constipation can overstretch the bowel and lead to 'overflow' diarrhoea.
Diarrhoea may occur if the bowel is irritated and overactive. A good daily routine will help minimise problems. Individuals should make sure they drink enough liquid every day. If so, talking to someone close to them or seeking outside help may be an answer. Some foods may overstimulate the bowel.
