Frequent urination

Frequent urination, or urinary frequency (Pollakiuria is the scientific terminology for the same), is the need to urinate more often than usual. 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. Frequent urination is strongly associated with frequent incidents of urinary urgency.

The normal number of times varies according to the age of the person. Among young children, urinating 8 to 14 times each day is typical. This decreases to 6 to 12 times per day for older children, and to 4 to 6 times per day among teenagers.
