The Most Common Bed Wetting Causes

Bedwetting is a common issue for many people that can affect both children and adults. Although it can be embarrassing, there are ways to help treat and control the condition. However, it’s important to understand the causes of bedwetting in order to effectively manage it. So, to help you identify the reason why you, your child or loved one is having difficulties remaining dry overnight, here are the most common bedwetting causes.

Common bedwetting causes

Small Bladder

A small bladder is a typical cause of bedwetting, especially for children. If the bladder is insufficient in size or not developed enough to hold the amount of urine produced throughout the night, bedwetting may occur.

Incomplete Toilet Training

For children, incomplete toilet training is another common cause of bedwetting. As children begin toilet training, they may be unable to recognise when their bladder is full and may not wake when they need to use the toilet. Poor daytime toilet habits can also contribute to this issue.

Deep Sleeper

For those who are deep sleepers, the inability to wake to a full bladder can be an issue.


A urinary tract infection (UTI) can make controlling urination difficult and the process painful. The infection and resulting bladder irritation can create urgency to urinate, making bedwetting and daytime accidents typical symptoms.


Due to a high level of sugar in the blood, people with diabetes can experience bedwetting. As the body tries to get rid of the sugar, urine output is increased and the need to urinate more frequently occurs.

Stress and Anxiety

Stress and anxiety have been known to trigger bedwetting. For children, typical stressful events include parental conflict and major changes, such as a new baby or starting school.

Family History

Bedwetting can be genetic, meaning that family history can be a cause. As such, if one or both of a child’s parents wet the bed as older children, it is likely that they will too.


It may surprise some, but constipation can actually be a common cause of bedwetting. As the same muscles are used to control urination and eliminate stool, their dysfunction from constipation can contribute to bedwetting.

Neurological Disorders

Abnormalities in the nervous system, as well as injury and disease of the nervous system, can affect urination control and cause bedwetting. Such issues can be common in stroke victims.
