It is well known that children with bedwetting are not able to wake up when they urinate at night. It has been believed for many years that the sleep of bedwetters is too deep, but recent research has indicated that children who wet the bed have poor quality sleep, waking up multiple times in the night. They may have many movements in the limbs during sleep, a sign that it may be related to attempts at arousal.
My 6 year old grandson has always wet the bed and his parents had the same problem – can bedwetting be a genetic disease?
Bedwetting is clearly a hereditary disease and in about 70% of cases there is at least one other family member who has or has had the same problem as a child. For example, if the mother suffered from bedwetting, there is a greater risk that her children will also suffer from bedwetting. No specific gene that causes bed-wetting has been identified, which is currently the research.
