The main symptom is when a child age 5 or older wets their bed or their clothes 2 times a week or more, for at least 3 months. But 1 in 10 children age 7, 1 in 20 children age 10, and 1 in 100 children older than 15 still have at least 1 episode of nighttime enuresis.

What stage of sleep does enuresis occur?

Because enuresis rarely occurs in REM sleep (17), the transition from intermittent NREM and REM sleep to prolonged nonarousable NREM sleep may cause enuresis to appear in a previously night dry child; this is known as secondary enuresis. Enuresis is also more likely to occur in the first two thirds of the night (18).

Why does enuresis happen?

Medical conditions that can trigger secondary enuresis include diabetes, urinary tract abnormalities (problems with the structure of a person's urinary tract), constipation, and urinary tract infections (UTIs). Psychological problems. Some experts believe that stress can be linked to enuresis.
