Most of us have had them, and for the most part they're merely annoying. But occasionally nosebleeds may be a warning sign of a serious problem. Among senior citizens, nosebleeds can signal an oncoming heart attack.
Nosebleeds also can be an indicator of high blood pressure problems.
Doctors at UT Southwestern Medical Center at Dallas say bringing your blood pressure under control should make the nosebleeds stop. Other causes of nosebleed are dried and irritated nasal mucosa, cocaine use, tumors, blood disorders, excessive nose blowing, nasal decongestants, and trauma to the nose. Picking your nose, in other words. First, the patient should blow their nose to remove any clots that may have formed. Tilt your head forward to ensure that no blood is swallowed.
