The elderly tend to experience heavy bleeding that fills up the nostril and causes blood to drip from the nose or into the throat when suffering from a nosebleed, explains WebMD. Excessive blood loss can lead to confusion, fainting, lightheadedness and dizziness. Some patients experience bleeding from other parts of the body, such as the gums or blood within bowel movements, when suffering from chronic bloody noses.
The elderly are more prone to nosebleeds from large vessels near the back of the nose, explains the American Academy of Family Physicians. This type of nosebleed can be dangerous and may require medical attention if the bleeding continues for more than 20 minutes. Elderly people are more at risk for a nosebleed stemming from large blood vessels because of high blood pressure, daily aspirin use, bleeding disorders and atherosclerosis, which are more common in older patients.
Nose bleeds are commonly the result of trauma to the inside or outside of the nose and irritation from a cold, according to WebMD. Certain diseases that block the blood from clotting, such as liver disease, cancers of the nose and abnormal blood vessels, make individuals more prone to nose bleeds. Blood-thinning drugs, such as aspirin or warfarin, contribute to the inability of the blood to clot.
