Hematuria

Blood in your urine can cause more than a little anxiety. Yet blood in urine — known medically as hematuria — isn't always a matter for concern. Strenuous exercise can cause blood in urine, for instance. So can a number of common drugs, including aspirin.

There are two types of blood in urine. Blood that you can see is called gross hematuria. Urinary blood that's visible only under a microscope is known as microscopic hematuria and is found when your doctor tests your urine. Either way, it's important to determine the reason for the bleeding.

Treatment depends on the underlying cause. Blood in urine caused by exercise usually goes away on its own within one or two days, but other problems often require medical care.
