Answer

Childhood acute diarrhea is usually caused by infection of the small and/or large intestine; however, numerous disorders may result in diarrhea, including a malabsorption syndrome and various enteropathies. Acute-onset diarrhea is usually self-limited; however, an acute infection can have a protracted course. By far, the most common complication of acute diarrhea is dehydration.
