Enuresis (Bed Wetting)


Enuresis is the medical term for bedwetting during sleep.

It is not considered abnormal until a child is older and wets the bed consistently (at least twice a week for 3 months or more).

Enuresis diagnostic criteria

  • Repeated voiding of urine into bed or clothes (whether involuntary or intentional)
  • Behaviour must be clinically significant as manifested by either a frequency of twice a week for at least three consecutive months or the presence of clinically significant distress or impairment in social, academic (occupational), or other important areas of functioning.
  • Chronological age is at least 5 years of age (or equivalent developmental level).
  • The behaviour is not due exclusively to the direct physiological effect of a substance (such as a diuretic) or a general medical condition (such as diabetes, spina bifida, a seizure disorder, etc.).
