What makes noses bleed

Two of the most common causes of nosebleeds are dryness often caused by indoor heat in the winter and nose picking. These 2 things work together — nose picking occurs more often when mucus in the nose is dry and crusty. Colds also can cause nosebleeds. Less common causes include injuries, allergies, or the use of illegal drugs, such as cocaine.

Children may stick small objects up their noses, and that can cause the nose to bleed. Older people may have atherosclerosis which is the hardening of the arteries , infections, high blood pressure , or blood clotting disorders that may cause nosebleeds. A rare cause of frequent nosebleeds is a disorder called hereditary hemorrhagic telangiectasia HHT.

Frequent nosebleeds may mean you have a more serious problem. For example, nosebleeds and bruising can be early signs of leukemia. Nosebleeds can also be a sign of a blood clotting or blood vessel disorder, or a nasal tumor both non-cancerous and cancerous. There is usually no need to formally diagnose a nosebleed.

A nosebleed can be scary to get — or see — but try to stay calm. Most nosebleeds look much worse than they really are. Almost all nosebleeds can be treated at home. If you get a nosebleed, sit down and lean slightly forward.

Keeping your head above your heart will slow the bleeding. Lean forward so the blood will drain out of your nose instead of down the back of your throat. If you lean back, you may swallow the blood. This can irritate your stomach. Use your thumb and index finger to squeeze together the soft portion of your nose.
