n.
frequent bowel evacuation or the passage of abnormally soft or liquid faeces. It may be caused by intestinal infections, other forms of intestinal inflammation (such as colitis or Crohn's disease), malabsorption, anxiety, and the irritable bowel syndrome. Severe or prolonged diarrhoea may lead to excess losses of fluid, salts, and nutrients in the faeces.
