If you see blood in your urine (hematuria) you are not alone. Up to 1 in every 5 people in the general population has hematuria. Sometimes, there is enough blood to change the color of the urine to orange, pink or, less often, darker red. While in many cases the cause is harmless, blood in urine can indicate something serious, like bladder cancer.
Seeing blood in your urine can be very frightening. There are many possible reasons for blood in the urine, not all of them a cause for concern. It is best to see your doctor to determine the reason for the bleeding.
