It reflects an increase in stool water content due to impaired water absorption and/or active water secretion by the intestine. Although the advent of oral rehydration therapy (ORT) has dramatically reduced the mortality rates in the past 50 years, diarrhea remains a major cause of morbidity and mortality in children, particularly among those in developing countries.
