Bedwetting (Nocturnal Enuresis) Symptoms & Causes

What causes nocturnal enuresis?

It's important to understand that bedwetting is usually not a behavioral problem, although it sometimes occurs if your child is feeling emotional stress or insecurity.

Some parents have the perception that their children are very "deep" sleepers, and that this is what has caused the bedwetting. However, studies have shown no difference in the sleep patterns of children who wet the bed as compared with other children.

There is more evidence suggesting that enuresis is the result of a developmental delay in the normal process of achieving nighttime control. The normal process involves the release of a hormone that prompts the kidneys to slow down production of urine during nighttime sleep. This hormone, called vasopressin, is not secreted in many children who have a problem at night.

There is no single cause for this condition, but researchers have discovered some genetic links, suggesting heredity may play a role.
