What Are the Causes of Excessive Urination in Toddlers?

Excessive urination, also referred to as polyuria, is a symptom in which too much urine is secreted, which can result in having to urinate frequently. Several medical conditions can cause excessive urination in toddlers. When this symptom occurs, have the child evaluated by a physician because some causes can be very serious.

Polycystic Kidney Disease

This kidney disorder is characterized by multiple cysts on the kidneys, resulting in the kidneys becoming enlarged. This disorder is inherited.

You can treat polycystic kidney disease by preventing complications and controlling the symptoms. You can treat high blood pressure associated with this condition with diuretic medications, blood pressure medications and a low-salt diet. Antibiotics will treat any associated urinary tract infections. Cysts that cause an obstruction or are painful or bleeding can be drained, according to MedlinePlus.

Type 1 Diabetes

This chronic disease is characterized by the pancreas not producing adequate insulin, resulting in the body not being able to control blood sugar levels properly. This causes too much glucose accumulating in the bloodstream so the body is unable to use it for energy. You can treat type 1 diabetes with insulin, diet changes, exercise and self-testing blood sugar levels.
