When a child who is old enough to have bladder control urinates accidentally while sleeping, it is called nocturnal enuresis.
Bedwetting is common for children, affecting more boys than girls. The condition occurs in 30% of children at the age of 4, 10% at the age of 6, and drops to 1% by the age of 18.
There are two main types of nocturnal enuresis: primary and secondary.
The primary type is a condition where a child still wets the bed after age 5 or 6. It\'s often hereditary.
The secondary type occurs when a child who had stopped bedwetting for at least six months starts again, often due to emotional stress or a medical condition.
Delay in maturation of bladder control, genetics, and sleeping soundly may be some of the causes for primary nocturnal enuresis. Causes of secondary nocturnal enuresis may include the following: emotional stress, urinary tract infection, and diabetes mellitus.
