What causes primary betwetting?

Primary bedwetting probably indicates immaturity of the nervous system. A bedwetting child does not recognize the sensation of the full bladder during sleep and thus does not awaken during sleep to urinate into the toilet. Primary bedwetting is also viewed as a delay in neurological maturation. The cause is likely due to one or a combination of the

following:

Maturational delay - delayed functional maturation of the central nervous system, which reduces the child's ability to inhibit bladder emptying at night. The child's bladder will fill, but the sensory output resulting from the stretching of the bladder is not perceived or is not sent to the brain and, thus, central cortical control over the urinary sphincter contraction does not occur. Failure of the arousal mechanism may also contribute to the inability to inhibit micturition.

Genetic (hereditary) factors - A family history of nocturnal enuresis is found in most children with the condition. If both parents wet the bed when they were younger, three out of four of their children will have bedwetting problems. If only one parent wet the bed as a child, the odds decrease to slightly less than half. If neither parent wet the bed as a child, the odds that a child will wet the bed drops to one out of seven. Recently, researchers have pinpointed chromosome 13 as the home of the bedwetting gene. Further research continues in this area.

Hormonal problems - A hormone called antidiuretic hormone, or ADH, causes a person's body to produce less urine at night. But some people's bodies don't make enough ADH, which means their bodies may produce too much urine while they're sleeping. Under normal circumstances, the body's level of a hormone that decreases the production of urine by the kidneys (antidiuretic hormone) rises during sleep, causing the bladder to fill more slowly. In some children who wet the bed, this nighttime rise in antidiuretic hormone does not happen as expected. Therefore, the amount of urine made remains the same as during waking hours, so the bladder continues to fill as much as it would during the daytime.

Behavior and Psychologic Factors - Psychologic factors are an unlikely cause of primary enuresis in children. However, things such as divorce, the death of a friend or family member, a move to a new town and adapting to a new school and social environment, or family tension can all feel overwhelming. It's not uncommon for people to feel stressed out during their teenage years, and stress can disturb sleep patterns.

More information on bedwetting

What is bedwetting? - Bedwetting, also called nocturnal enuresis, means that a child accidentally passes urine at night during sleep.
What is primary nocturnal enuresis? - Primary nocturnal enuresis means bedwetting that has been ongoing since early childhood without a break.
What is secondary nocturnal enuresis? - Secondary bedwetting is a sign of an underlying medical or emotional problem. Secondary bedwetting is related to sexual abuse or to extreme bullying.
What causes betwetting? - Bed wetting is usually caused by a delay in the maturation of the part of the nervous system that controls bladder function.
What causes primary betwetting? - Primary bedwetting probably indicates immaturity of the nervous system. Primary bedwetting is a delay in neurological maturation.
What causes secondary bedwetting? - Secondary bedwetting may be related to sexual abuse or to extreme bullying. The child with secondary bedwetting is more likely to have other symptoms.
How is bedwetting diagnosed? - Diagnosis of bedwetting is based on several tests. Voiding cystourethrogram (VCUG) is a specific x-ray that examines the urinary tract.
What's the treatment for bedwetting? - Behavioral conditioning in the treatment of primary nocturnal enuresis is based on the use of a signal alarm device.
How to help your children avoid bedwetting? - Bedwetting can be possibly prevented by limiting fluids after dinner, urinating before going to bed, recording wet and dry nights.
