Patience on the part of parents, along with some simple steps, can help cure nighttime bedwetting, or primary nocturnal enuresis, among kids.
While most of the children outgrow this condition, others continue wetting the bed up to the age of 6-7 years, which could eventually raise social and psychological issues.
The condition happens more often in boys than in girls, and tends to run in families.
Dr. Paul Austin, associate professor of surgery at Washington University in St. Louis and a paediatric urologist at St. Louis Children's Hospital, said that bedwetting is not due to a behavioural or mental problem or laziness of the child.
Instead, some of the most common causes of bedwetting include genetic factors, lack of anti-diuretic hormone (ADH) or vasopressin, which is produced normally at night to limit the formation of urine during sleep.
Nighttime bed-wetting could also be caused when a full bladder fails to communicate with the brain to wake up the child or the bladder is too small for his or her age.
Usually, all these common causes are temporary, and resolve as the child matures.
Parents should exercise patience with their child, and understand that their child is not wetting the bed on purpose.
Austin said that the parents should also encourage the child and let him or her know that they will eventually be able to stay dry at night.
