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.

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
• Stroke and other neurological diseases

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

Follow the therapy recommended by your doctor to treat the underlying cause of your urinary frequency or urgency. It may help to keep a diary of times and amounts of urine voided to bring with you to the doctor.

In some cases, you may experience some urinary incontinence for a period of time. You may need to take steps to protect your clothing and bedding.
