Diarrhoea: Loose, water like stools that occur with increased frequency and an increased volume of >200g per day
Gastroenteritis: >3 or more loose stools per day for <14 days
Chronic Diarrhoea: Diarrhoea that continue for more than 2 weeks
Malabsorption: Defined as the failure to absorb nutrients
Toddlers Diarrhoea: Clinical syndrome characterised by chronic diarrhoea often with undigested food in the stools of a child who is otherwise well, gaining weight and growing satisfactorily.
Gastroenteritis is usually self-resolving. Parasitic infection are uncommon but can be dangerous.
|Clinical Triad of Gastroenteritis: fever, vomiting, diarrhoea
