There are number of risk factors which are predisposing to the development of bedwetting
Age: - Nocturnal Enuresis is more common in boys than girls and seen mostly in children above 5yrs of age
Genetics- A strong family history of parents with Nocturnal enuresis can trigger the episodes. If both parents are enuretic as a child then their child has 77 % risk of having bedwetting
Developmental delay- Children with gross developmental delay like Down syndrome have more risk of bedwetting. Even children with delayed developmental milestones, premature delivery or behavioral disorders such as hyperactivity disorder are more prone to develop enuresis.
Disorders in nervous system- Neurological problems such a Spina bifida, cerebral palsy can produce bedwetting
Excess fluid intake- consumption of excess water increases the urine output and predispose to bedwetting. Sometimes tea, coffee, high energy drinks can also cause bedwetting
Psychological stress- Any mental stresses in child life like separation from mother, bullying, death of parents are more prone to develop bedwetting.
