Bedwetting (or enuresis or '"sleepwetting"') is involuntary urination while asleep. It is the normal state of affairs in infancy, but can be a source of embarrassment when it persists into school age or beyond.

In medicine, polyuria is a condition characterized by the passage of large volumes of urine (at least 2.5 L over 24 hours in adults).
