The lining of your nose contains many tiny blood vessels that lie close to the surface and are easily damaged.

The two most common causes of nosebleeds are:

  1. Dry air — when your nasal membranes dry out, they're more susceptible to bleeding and infections
  2. Nose picking

Other causes of nosebleeds include:

  1. Sinusitis aguda
  2. Alergias
  3. Aspirin use
  4. Hemofilia (and other bleeding disorders)
  5. Blood thinners (anticoagulants), such as warfarin and heparin
  6. Chemical irritants, such as ammonia
  7. Sinusitis crónica
  8. Cocaine use
  9. Resfriado común
  10. Tabique nasal desviado
  11. Foreign body in the nose
  12. Nasal sprays, such as those used to treat allergies, if used frequently
  13. Rinitis no alérgica
  14. Trauma to the nose

Less common causes of nosebleeds include:

  1. Alcohol use
  2. Hereditary hemorrhagic telangiectasia
  3. Púrpura trombocitopénica idiopática
  4. Leucemia
  5. Pólipos nasales
  6. Nasal surgery
  7. Nasal tumor
  8. Segundo trimestre del embarazo

In general, nosebleeds are not a symptom or result of high blood pressure. It is possible, but rare, that severe high blood pressure may worsen or prolong bleeding if you have a nosebleed.
