Urination, Excessive or Frequent

By Anuja P. Shah, MD

Most people urinate about 4 to 6 times a day, mostly in the daytime. Normally, adults pass between 3 cups (700 milliliters) and 3 quarts (3 liters) of urine a day. Excessive urination can refer to

  • An increased volume of urine (polyuria)

  • A normal volume of urine with the need to go more often (urinary frequency)

  • Both

Urinary frequency may be accompanied by a sensation of an urgent need to urinate (urinary urgency). Many people particularly notice polyuria because they have to get up to urinate during the night (nocturia). Nocturia also can occur if people drink too much fluid too close to bedtime, even if they drink no more than normal overall.
