Udredning af barnet med kronisk diare

Causes of chronic diarrhoea (CD) are numerous. At the first consultation it is possible by simple means to evaluate the child for common causes and screen for the more severe ones: infection, food allergy, disaccharide malabsorption, general malabsorption (celiac disease and cystic fibrosis), inflammatory bowel disease, and functional disorders (toddler's diarrhoea and irritable colon syndrome). Second line evaluation should take place in the paediatric ward, aiming to confirm suspected, complicated disorders and to explore the possibility of the large number of rare causes of CD in the seriously sick child.
