Frequent urination

 

Frequent urination means needing to urinate more often than usual. Urgent urination is a sudden, compelling urge to urinate, along with discomfort in your bladder.

A frequent need to urinate at night is called nocturia. Most people can sleep for 6 to 8 hours without having to urinate. Middle aged and older men often wake to urinate once in the early morning hours.


Alternative Names
Urgent urination; Urinary frequency or urgency


Common Causes

 

Together, frequent and urgent urination are classic signs of a urinary tract infection. Since inflammation reduces the bladder's capacity to hold urine, even small amounts of urine cause discomfort.

Diabetes, pregnancy, and prostate problems are other common causes of these symptoms.

 

Other causes include:

 

Interstitial cystitis
Medicines such as diuretics
Overactive bladder syndrome
Prostatitis
Stroke and other neurological diseases
Urinary incontinence


Less common causes:

 

Bladder cancer
Bladder dysfunction
Radiation therapy


Common causes of nighttime urination:

 

Drinking too much before bedtime, especially caffeine or alcohol
Enlarged prostate
