Urinary frequency

Frequent urination, or urinary frequency, is the need to urinate more often than usual.[1] It is often, though not necessarily, associated with urinary incontinence and polyuria (large total volume of urine). However, in other cases, urinary frequency involves only normal volumes of urine overall.

A frequent need to urinate at night is called nocturia.[1] Frequent urination is strongly associated with frequent incidents of urinary urgency.
