[Intestinal malabsorption in the child].

Intestinal malabsorption in the child usually manifests by chronic diarrhoea and (or) deficiency of growth and weight gain. Given the wide diversity of causes, diagnosis is primarily based on history-taking and clinical examination, which subsequently directs investigations. Stool examination was long the reference to confirm malabsorption and to determine its mechanisms: impaired digestion (external pancreatic insufficiency), malabsorption (intolerance to cow's milk proteins or to gluten), fermentation (intolerance to primary or secondary sugars). Presently, however, the diagnosis is usually made on the basis of several simple examinations.
