Causes of Bedwetting

What actually causes bedwetting?

Three are two types of bed wetting:

  • Primary Bedwetting (or Primary Nocturnal Enuresis) where a child has never achieved bladder control at night, and
  • Secondary Bedwetting (or Secondary Nocturnal Enuresis) where a child starts bedwetting after having been dry at night for at least 6 months prior to the bedwetting.

Primary Bedwetting is usually the result of developmental delay in the normal bladder reflex system. In bed wetters the signal to wake when the bladder is full is either weak or inoperative and the bladder reflex system allows automatic, involuntary voiding when the bladder fills above a certain level. In some cases primary bed wetters may also not produce enough of the hormone ADH which reduces night-time urine production so they can sleep through the night. Genetics do play a part –a child has a 40% chance of becoming a bed wetter if one parent wet the bed when young and a 70% chance if both parents did. Recent studies have also identified genes associated with nocturnal enuresis.

Secondary Bedwetting is not common, occurring in only 1-2% of cases, and can be the result of a medical condition, e.g. a bladder infection, or emotional stress. It is recommended that you seek medical advice to rule out any particular medical condition.

My daughter loves the alarm. She’s told me to ‘sell my pull-ups on eBay mommy’. She just loves that she doesn’t have to wear pull-ups…
