Frequent Urination (cont.)

Common Causes of Frequent Urination

  • Urinary tract infection: The lining of the urethra (the tube that carries urine from the bladder out of the body) and bladder becomes inflamed and irritated due to byproducts of an infection (blood, white blood cells, bacteria). This irritation of the bladder wall causes the urge to empty the bladder frequently (called frequency).
  • Diabetes: An early symptom of both type 1 and type 2 diabetes can be frequent urination, as the body tries to rid itself of unused glucose (blood sugar) through the urine. Diabetes can also damage the nerves that control the bladder, causing frequent urination and difficulty controlling your bladder
  • Diuretic use: Medications used to treat high blood pressure or fluid buildup work in the kidney and flush excess fluid from the body, causing frequent urination.
  • Prostate problems: An enlarged prostate can press against the urethra and block the flow of urine, causing the bladder wall to become irritated. The bladder contracts even when it contains small amounts of urine, causing more frequent urination.
  • Pregnancy: Hormonal changes and the growing uterus placing pressure on the bladder cause frequent urination, even in the early weeks of gestation. The trauma from vaginal childbirth can also cause damage to the urethra.
  • Interstitial cystitis: This condition is characterized by pain in the bladder and pelvic region, often leading to frequent urination.
  • Stroke or other neurological diseases: Damage to nerves that supply the bladder can lead to problems with bladder function, including frequent and sudden urges to urinate.
  • Bladder cancer: Tumors taking up space or causing bleeding in the bladder may lead to more frequent urination.
  • Overactive bladder syndrome: Often frequent urination is itself the problem. Involuntary bladder contractions lead to frequent and often urgent urination, even if the bladder is not full.
  • Drinking too much: Ingesting more fluids than your body needs can cause the body to urinate more often.
  • Artificial sweeteners, alcohol, caffeine and other foods: Alcohol and caffeine can act as diuretics, which can cause more frequent urination. Carbonated drinks, artificial sweeteners (such as Splenda or Equal), and citrus fruits are known to irritate the bladder, causing more frequent urination.
