What causes bedwetting?
Bedwetting often has no particular cause. In a few cases, there is an underlying physical or psychological cause. Factors that can raise the chance of a child wetting their bed include: a family history of bedwetting; constipation and other digestion problems; being a boy; being a deep sleeper; small or overactive bladder, or; drinking a lot before bedtime. Emotional factors are not a major influence on bedwetting. However, stress or changes in circumstance can occasionally trigger or increase bedwetting in a child.
