A few nosebleeds stem from large vessels in the back of the nose. These nosebleeds can be dangerous. They may occur after an injury. This type of nosebleed is more common in the elderly and is often due to high blood pressure, atherosclerosis, daily aspirin use or bleeding disorders. Usually, the older the patient, the more serious the nosebleed.
