Bloody Urine, Dangerous or Not?

Having bloody urine, or hematuria, may not be dangerous or it can be a sign of a more serious health problem.

Bloody urine occurs when red blood cells—the blood cells that make the color of blood red—are found in the urine. The color of urine may vary from pale pink to the color of cola. Sometimes, you might have hematuria but are not aware of it because it is not seen with the naked eye. This is termed as microscopic hematuria. This type, can only be detected if viewed under a microscope.

Gross hematuria is the term used when blood is present in your urine and can be seen by the naked eye.

There are several conditions that can cause hematuria including kidney stones passing through the urinary tract, glomerular disease, Henoch – Schönlein Purpura (HSP), and Medullary sponge kidney. In some cases, hematuria may occur after performing strenuous exercises, which goes away within 24 hours. While sometimes, bloody urine (hematuria) is not dangerous, it can also be a sign of a tumor or serious health problem. You should ask your doctor if you need to be tested.

Sometimes, the condition can occur as a result of diagnostic testing to view the urinary tract like cystoscopy and ureteroscopy. However, hematuria should not last for more than 24 hours after the test.


Hematuria treatment depends on the cause. For example, if a kidney stone is causing the condition, removing, breaking, or naturally flushing the stones may make hematuria go away. If no serious health problem is causing hematuria, special treatment may not be necessary.
