Doctor's Notes on Frequent Urination

Frequent urination is characterized by urinating frequently throughout the day (typically 8 times or more) or having to wake up at night to urinate. Frequent urination can be caused by a wide variety of conditions. Pregnancy may lead to frequent urination. Taking diuretic medications can also cause frequent urination. Other possible causes include diabetes, urinary tract infection, prostate problems such as enlargement of the prostate, and interstitial cystitis.

Frequent urination is often accompanied by other signs and symptoms, which vary according to the cause of the problem. Associated signs and symptoms can include painful urination, blood in the urine, feeling a pressing need to urinate (urgency), difficulty starting a urine stream, cloudy urine, and thirst. Other symptoms may include fatigue, weight loss, increased hunger, and signs of dehydration.
