Frequent urination, or urinary frequency, 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.
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.
Frequent urination is a classic sign of urinary tract infection, where inflammation reduces the bladder's capacity to hold urine. Other common causes are:
- Diabetes mellitus, causing increased urine production (polyuria)
- Prostate problems, causing disturbance along the urinary tract
Other causes of polyuria may, less commonly, cause frequent urination.
Other causes of frequent urination may be as a result from a disturbance along the urinary tract, including:
- Interstitial cystitis
- Overactive bladder
- Urinary retention
- Benign prostatic hyperplasia
- Stroke and other neurological diseases
