(HealthDayNews) -- Blood in the urine can indicate a serious health problem. The most likely cause is a urinary tract infection, and the condition should not be ignored, even if you have no other symptoms.
"If you see blood, you definitely need to see a doctor," says Dr. Jeffry Huffman, a urologist at the University of Southern California.
Urinary tract infections are common. Symptoms include burning during urination or frequent urination. But sometimes there are no obvious symptoms until blood appears in the urine.
Kidney stones and bladder cancer are other, more serious causes of the condition.
