Not all of the causes of bedwetting are known. Research suggests that some of the following factors may lead to bedwetting:
Not waking to bladder signals
Just as our children reach developmental milestones at different ages, learning to control their bladder during the night is yet another stage. Your child may have crawled, walked and talked just like his/her peers but for your child staying dry at night is taking longer to master.
Bedwetting does tend to run in families. If one or both parents used to wet the bed when they were children, then it is quite likely to occur in their children.
Recent research has found that many children who wet the bed produce less of a hormone known as antidiuretic hormone (ADH) during sleep. This hormone normally reduces urine production during sleep. These children produce more urine during the hours of sleep than their bladders can hold. If they do not wake up, the bladder releases the urine and the child wets the bed.
In some rare cases, there may be a physical problem that is the cause of the child’s bed-wetting. For this reason, it is very important that a General Practitioner (GP) examines your child.
