The exact cause of primary enuresis is not fully understood, but several factors may contribute to this condition:
Genetic predisposition: Bedwetting often runs in families. Developmental delay: The child may have a slower development of bladder control. Sleep disorders: Children with deep sleep patterns may not wake up when their bladder is full. Hormonal factors: A deficiency in antidiuretic hormone (ADH) may result in increased urine production at night. Small bladder capacity: The child’s bladder may not be large enough to hold urine produced during the night.
