Acute gastroenteritis in children.
BACKGROUND
Acute gastroenteritis is a common childhood illness. Most cases are caused by rotavirus infection.


OBJECTIVE
This article discusses the classic presentation of gastroenteritis in children, which includes a short history of vomiting followed by diarrhoea.


CONCLUSIONS
Dehydration is the main problem in children with gastroenteritis, and severe dehydration is a medical emergency. Mild to moderately dehydrated children can be safely treated at home with oral rehydration therapy, however parents require careful explanation of the disease, its course and potential complications. Early reintroduction of usual foods (breast milk, formula or solids) has been shown to shorten the illness. Babies may need to be reviewed within 8 hours and older children within a day.
