Q. 20

Define diarrhoea.

Class 9th Dr. P.S. Verma & Dr. V.K. Agarwal - Biology 5. Why Do We Fall Ill?

Answer :

Diarrhoea is defined as the passage of three or more loose or liquid stools per day (or more frequent passage than is normal for the individual). Frequent passing of formed stools is not diarrhoea, nor is the passing of loose, "pasty" stools by breastfed babies.
