Episode of severe diarrhoea

Irritable bowel syndrome - Episode of severe diarrhoea Factor

Diarrhoea is the acute onset of the passage of frequent loose watery motions accompanied by a marked urgency to defaecate. For diarrhoea to be a factor in the development of irritable bowel syndrome it must be an acute illness, caused by an infective organism, and of sufficient severity to warrant medical attention, or in the absence of medical intervention, lasting at least four days.
