What Are the Causes of Excessive Urination in Toddlers?

There are several causes of excessive urination in toddlers, including some serious medical conditions. If your toddler is experiencing frequent urination, it is important to be aware of any other unusual symptoms or behaviors.

Urinary Tract Infection

Signs of a urinary tract infection often include excessive urination, feeling the need to urinate suddenly, and a burning sensation when urinating. Your toddler will need a urine test to diagnose the condition.

Diabetes Mellitus

Excessive urination in toddlers is one of the main symptoms of diabetes mellitus. If your child feels an excessive need to urinate, along with excessive thirst, increased appetite, unusual bed wetting or unexplained weight loss, her pediatrician should administer a urine test.

Diabetes Insipidus

With diabetes insipidus, your toddler will produce an abnormally large amount of urine, which often is matched by excessive thirst. If he is not drinking enough fluids to make up for what is lost during urination, he may experience dehydration.

Voiding Problems

Some toddlers simply do not allow their bladders to empty when they urinate. Over time, it actually becomes difficult for the child to empty completely, resulting in frequent urination.

Stress

Frequent and excessive urination simply may be the result of emotional stress your toddler feels. If you notice the increase in urination within one or two days of a stressful event, it is likely just a coping mechanism that will disappear on its own.
