How many watery stools in a 24-hour period defines diarrhea?

The diagnosis of diarrhea in children is typically defined by the presence of three or more watery stools in a 24-hour period. This criterion helps to differentiate between normal bowel movements and abnormal frequency that may indicate a diarrhea episode. The emphasis on three or more stools is based on clinical observations and research showing that this threshold is significant enough to warrant concern and indicate potential fluid loss and dehydration risks. Recognizing diarrhea early is crucial for initiating appropriate management, including rehydration strategies and monitoring for signs of worsening illness. This definition aligns with standards used by health organizations, making it a widely accepted criteria in clinical practice.
