There can be a variety of causes, including a small bladder, an immature bladder that does not always empty appropriately, a family history that makes bedwetting more likely, deep sleeping, stress, and increased urine production at night that may be related to abnormal secretion of hormones that affect urine volume.

This stress can cause bedwetting; treating the stress can stop the bedwetting. Deep sleep. A deep sleep pattern can be part of normal adolescent development, as can a poor sleep schedule and too few hours of sleep. This is all common during puberty and especially during a teen’s high school years.

Secondary enuresis is a condition that develops at least six months — or even several years — after a person has learned to control his or her bladder. Secondary nocturnal enuresis (SNE) accounts for about one quarter of children with bedwetting. By age ten years, up to 8% of children will develop SNE.

Some of the causes of bed-wetting include the following: Genetic factors (it tends to run in families) Difficulties waking up from sleep. Slower than normal development of the central nervous system—this reduces the child’s ability to stop the bladder from emptying at night.
