What causes nose bleeding?

Question: What causes nose bleeding?

A nosebleed, also known as epistaxis, is caused by the rupture of a blood vessel in the lining of the nose. The lining of the nose is very vascular, meaning that it has a lot of blood vessels. These blood vessels are easily irritated and can rupture, causing a nosebleed.

There are many things that can cause a nosebleed, including:

• Picking or rubbing the nose
• Blowing the nose too hard
• Getting hit in the nose
• Dry air
• Sinus infections
• Allergies
• High blood pressure
• Blood thinners
• Certain medications, such as aspirin and ibuprofen
• Certain medical conditions, such as liver disease and leukemia

Most nosebleeds are not serious and will stop on their own or with home treatment. However, if you have a nosebleed that is severe, frequent, or doesn't stop after 15 minutes, you should see a doctor.

Here are some tips to help prevent nosebleeds:

• Avoid picking or rubbing your nose.
• Use a humidifier or take a hot shower to add moisture to the air.
• Blow your nose gently.
• If you have allergies, take medication as prescribed by your doctor.
• If you take blood thinners, talk to your doctor about how to reduce your risk of nosebleeds.
