Excessive volume of urination means that you release abnormally large amounts of urine each day. The medical term for this condition is polyuria.
An excessive volume of urination for an adult is more than 2.5 liters of urine per day.
Polyuria is a fairly common symptom, which is often noticed when you have to get up to use the bathroom at night.
