Frequent urination

Frequent urination, or urinary frequency (sometimes called pollakiuria), is the need to urinate more often than usual. Diuretics are medications that increase urinary frequency. Nocturia is the need of frequent urination at night. The most common cause of this condition for women and children is a urinary tract infection. The most common cause of urinary frequency in older men is an enlarged prostate.

Frequent urination is strongly associated with frequent incidents of urinary urgency, which is the sudden need to urinate. 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.
