High Quality Content by WIKIPEDIA articles! Bedwetting is involuntary urination while asleep after the age at which bladder control would normally be anticipated. The medical term for this condition is "nocturnal enuresis." Primary nocturnal enuresis (PNE) is when a child has not yet stayed dry on a regular basis. Secondary nocturnal enuresis (SNE) is when a child or adult begins wetting again after having stayed dry. Bedwetting is the most common pediatric-health issue. Studies show that parents become worried too quickly because they expect children to stay dry too early. Most girls can stay dry by age six and most boys stay dry by age seven. By ten years old, 95% of children are dry at night. Studies place adult bedwetting rates at between 0.5% to 2.3%.
