Excessive amount of urination means that your body makes larger than normal amounts of urine each day.
An excessive volume of urination for an adult is more than 2.5 liters of urine per day. However, this can vary depending on how much water you drink and what your total body water is.
Polyuria is a fairly common symptom. People often notice the problem when they have to get up during the night to use the bathroom (nocturia).
