Urine - bloody

  • Definition
    • Blood in your urine is called hematuria. The amount may be very small and only detected with urine tests or under a microscope. In other cases, the blood is visible. It often turns the toilet water red or pink. Or, you may see spots of blood in the water after urinating.

  • Alternative Names
    • Hematuria; Blood in the urine

  • Causes
    • There are many possible causes of blood in the urine.

      Bloody urine may be due to a problem in your kidneys or other parts of the urinary tract, such as:

      If there is no structural or anatomical problem with your kidneys, urinary tract, prostate, or genitals, your doctor may check to see if you have a bleeding disorder. Causes may include:

      Blood that looks like it is in the urine may actually be coming from other sources, such as:

      • The vagina (in women)
      • Ejaculation, often due to a prostate problem (in men)
      • A bowel movement

      The urine can also turn a red color from certain drugs, beets, or other foods.

  • Home Care
  • When to Contact a Medical Professional
    • You may not see blood in your urine because it is a small amount and is microscopic. Your health care provider may find it while checking your urine during a routine exam.

      Never ignore blood you see in the urine. Get checked by your provider, especially if you also have:

      • Discomfort with urination
      • Frequent urination
      • Unexplained weight loss
      • Urgent urination

      Call your provider right away if:

      • You have fever, nausea, vomiting, shaking chills, or pain in your abdomen, side, or back
      • You are unable to urinate
      • You are passing blood clots in your urine

      Also call if:

      • You have pain with sexual intercourse or heavy menstrual bleeding. This may be due to a problem related to your reproductive system.
      • You have urine dribbling, nighttime urination, or difficulty starting your urine flow. This may be from a prostate problem.
  • What to Expect at Your Office Visit
    • Your provider will perform a physical exam and ask questions such as:

      • When did you first notice blood in your urine? Has the amount of your urine increased or decreased?
      • What is the color of your urine? Does your urine have an odor?
      • Do you have any pain with urination or other symptoms of infection?
      • Are you urinating more often, or is the need to urinate more urgent?
      • What medicines are you taking?
      • Have you had urinary or kidney problems in the past, or recently had surgery or an injury?
      • Have you recently eaten foods that may cause a change in color, like beets, berries, or rhubarb?

      Tests that may be done include:

      The treatment will depend on the cause of blood in the urine.
