Nosebleeds: Causes, Treatment, and When to Seek Help

Nosebleeds happen when delicate blood vessels inside the nose break and bleed. Most nosebleeds are minor and stop on their own with simple first aid. Common causes include dry air, nose picking, and minor injuries. Seek medical care if bleeding is heavy, lasts more than 20 minutes, or happens after an injury.

In plain words

Nosebleeds happen when tiny blood vessels in the nose break and bleed. They are common and usually not serious. Most nosebleeds happen in the front part of the nose and stop quickly with simple care. Dry air, nose picking, colds, and allergies are common causes. Some people get nosebleeds more often, especially children and older adults. If a nosebleed lasts longer than 20 minutes or you lose a lot of blood, see a doctor right away.

What is Nosebleeds: Causes, Treatment, and When to Seek Help?

Nosebleeds happen when delicate blood vessels inside the nose break and bleed. Most nosebleeds are minor and stop on their own with simple first aid.

Symptoms

Early symptoms

  • Early signs of nosebleeds: Early symptoms vary depending on the underlying cause. See a doctor for evaluation if you notice unusual changes. (1) (2)

Causes

Primary causes

  • Dry air: Low humidity dries out nasal membranes, making them more likely to crack and bleed. This is especially common in winter or in dry climates. (5) (2)
  • Nose picking or irritation: Scratching or picking the inside of the nose can damage blood vessels, especially in children. (2) (4)
  • Cold or allergies: Frequent sneezing, blowing the nose, or using nasal sprays can irritate nasal passages. (5)

Risk factors

Age

Children ages 2-10 and adults over 50 are more likely to get nosebleeds due to differences in blood vessel fragility. (5)

Medications

Blood thinners, aspirin, or anti-inflammatory drugs can increase bleeding risk. (2) (5)

Medication options

Lifestyle and self-care

  • First aid for nosebleeds: Sit up straight, lean forward slightly, and pinch the soft part of your nose for 10-15 minutes without checking. Apply a cold compress to the bridge of the nose. Avoid tilting the head back, as this can cause blood to flow down the throat. (1) (3)
  • Preventing dryness: Use a humidifier, apply petroleum jelly inside the nostrils, or use saline nasal spray to keep nasal passages moist. (6)

Always discuss dosing and treatment changes with your own prescriber.

When to see a doctor

Routine follow-up

  • Schedule an appointment if you get frequent nosebleeds (more than once a week) or they interfere with daily activities. (7)

Seek emergency care

  • Seek immediate medical care if bleeding lasts more than 20 minutes despite first aid, you lose a large amount of blood, or you feel weak or dizzy. (7) (6)
  • Get emergency help if the nosebleed follows a head injury, as this could signal a skull fracture. (7)
