The main symptom is involuntary urination, usually at night, that occurs at least twice per month.
Signs and tests
Your child's doctor will discuss the history of bedwetting in detail. You can help by keeping a detailed diary that outlines normal urination and wetting episodes, fluid and food intake (including time of meals), and sleep times.
A physical examination should be performed to rule out physical causes. A urinalysis will be done to rule out infection or diabetes.
X-rays of the kidneys and bladders and other studies are not needed unless there is reason to suspect some other problems.
