Rupture of the blood vessels that are very close to the surface of the lining of the nose.
An abnormal growth (polyp or tumor) in the nose or sinuses.
Health conditions that affect normal blood clotting.
Abnormal blood vessels in the nose, such as with Osler-Weber-Rendu syndrome. This syndrome is passed in families (inherited). The abnormal blood vessels make it hard to control a nosebleed.
A nosebleed that recurs 4 times or more in a week needs medical evaluation to determine the seriousness of the problem. A nosebleed that recurs 2 to 3 times in a month may mean that a chronic condition such as allergies is causing the nosebleeds.
When nosebleeds cannot be controlled by home treatment, you need to see your doctor.
