Diarrhea in Children
Key Points
Diarrhea is a common pediatric concern. Gastroenteritis is the most common cause. Testing is rarely necessary in children with acute diarrheal illnesses. Dehydration is likely if diarrhea is severe or prolonged. Oral rehydration is effective in most cases. Antidiarrheal drugs (eg,loperamide) are not recommended for infants and young children.
