In the United States, bedwetting is a problem for as many as 5 million children, according to the National Institutes of Health. While there's no set age that children grow out of bedwetting, each year as children grow older, fewer and fewer experience enuresis.
Bed-wetting is common prior to puberty, affecting about 15% of kids. It often runs in families, and boys are more likely to wet the bed than girls. However, girls will have more day accidents than boys.
Experts haven't yet pinpointed the exact cause or causes of bedwetting, but they do know that certain factors contribute to the problem.
"We know there's a genetic component. If both parents have a history of bedwetting, there's at least a 70 percent chance that the child will,"
One issue may be contributing there's also a connection between sleep cycles and bedwetting, and that the reflex that suppresses urine discharge is suppressed at night in children who wet the bed. Now what might be happening to the bedwetter is their bladder is constantly sending signals to arouse the brain may end up being ignored in its time of greatest need.
Another possible factor is a hormone called anti-diuretic hormone that keeps the body from excreting fluids. "Children who wet the bed don't make enough anti-diuretic hormone.
So, there is multiple contributing factors as poor communication from the bladder-brain dialogue to the brain and also possible the child is not producing enough anti-diuretic hormone to suppress their kidneys. So instead of taking all night for the bladder to fill it fills up before waking.
