The main causes of bedwetting in children may include enuresis, delayed bladder development, urinary tract infections, pinworm disease, or spinal defects. It is recommended that parents take their children to a regular hospital for examination to confirm and treat the relevant diseases.

Bedwetting occasionally after the age of four may be due to physiological enuresis, with most children no longer wetting the bed after the age of five. If bedwetting persists frequently after the age of five, it may be ’nocturnal enuresis’. Parents should promptly take their child to a top-tier hospital for examination and treatment, and undergo regular checks and symptomatic medication.
