Blood in Your Urine or Stool

Blood in Your Urine or Stool

Blood in your stool can be caused by several different medical conditions, including hemorrhoids, anal fissures or cracks, inflammation of the colon or peptic ulcers. However, it’s also a sign of colorectal cancer.

Blood in your urine can signal bladder or kidney infections or stones; it may also be the result of certain medications, or over-vigorous exercise. But in some cases, blood in the urine can indicate bowel or kidney cancer. If you see blood in your urine or stool, it’s important to let your doctor know, so that he or she can pinpoint the cause.
