Nocturnal enuresis describes involuntary urination during which period?

• A. During sleep.
• B. During waking hours.
• C. Only during exercise.
• D. Only at bedtime.

Answer: (A)

Nocturnal enuresis means urinating involuntarily during sleep, typically at night when you’re asleep and not actively controlling the bladder. The word nocturnal points to the night, and enuresis means involuntary urination. This is different from diurnal enuresis, which would occur during waking hours. While some people might only wet right at bedtime, nocturnal enuresis specifically describes events that happen during sleep, when arousal and bladder control aren’t synchronized well enough to prevent leakage.
