Definition of diarrhea?

Definition of diarrhea?

• A. Stool color change
• B. Abdominal pain with constipation
• C. Passage of loose or watery stools at least three times in 24 hours
• D. Increased stool water content

Answer: (C)

Diarrhea is defined by an abnormal increase in stool liquidity and/or frequency. The standard clinical criterion is three or more loose or watery stools within a 24-hour period, which captures both how the stool looks and how often it passes. This threshold helps distinguish diarrhea from normal daily variation in bowel habits. The other options describe related features but don’t meet the diagnostic threshold: a color change can occur with various conditions and isn’t itself diagnostic of diarrhea; abdominal pain with constipation points to a different pattern altogether; and simply noting increased stool water content describes one component of diarrhea but not the frequency criterion that defines it.
