Recurrent diarrhoea in children.

Diarrhoea can be defined as the passage of loose stools and increased 
bowel frequency above the accepted norm for the individual and resulting 
in excess loss of water and electrolytes in the faeces. It 
may or may not be associated with steatorrhea (fatty stools). History 
plays a vital part in the diagnosis of gastro-intestinal disease in 
children. Time spent here is often more rewarding than a battery 
of specialised investigations. One must be clear what the parent means 
by diarrhoea, as terminology among doctors, nurses, and parents is often 
confusing. When dealing with children one must always adopt a comprehensive 
approach and consider the whole child and his family. Common causes, 
mechanisms, and consequences are discussed. Some of the common causes of 
diarrhoea are cystic fibrosis, gluten-induced enteropathy (coeliac disease), Giardia lamblia, sugar 
intolerance, gastro-intestinal allergy, and irritable bowel syndrome.
