Diseases Associated With Nosebleeds

Bleeding from your nose can be quite scary, but nosebleeds are actually pretty common and most of the time they don’t indicate any serious health problems.  Blood vessels located around the surface of the nose are usually very fragile and cause nosebleeds easily, and this is in fact the cause of an anterior nosebleed, which is the most common type. On the other hand, a posterior nosebleed happens in the inner parts of the nose and flows down the back of the throat, which means there can be an underlying issue.


Nosebleeds are very common and can be caused by various reasons, but the most common is living in an area with cold and dry air. This can lead to dried out nasal tissue and crusting in the nose, which may become irritated and can bleed if accidentally scratched. Here are other causes of a nosebleed:

  • Picking the nose
  • Cold air
  • Repeated sneezing/blowing of the nose
  • Injury
  • Allergic reaction
  • Chemical irritants
  • Foreign object stuck in the nose


There are also several diseases associated with nose bleeds.



Aplastic anemia, to be specific, can cause one to bleed through their nose. This type of anemia occurs when the bone marrow fails to produce new blood cells because of damage done to it. In this case, the bone marrow contains nothing or very few blood cells.


This can be caused by long and frequent exposure to toxic chemicals, a side effect to certain medications, radiation and chemotherapy, autoimmune disorders, or pregnancy.



Hemophilia is a genetic disorder that prevents your blood from clotting normally after a cut or trauma because of the lack of blood clotting proteins. This poses a risk of internal bleeding and can damage your organs. Hemophilia can also cause nosebleeds with any apparent cause.



Leukemia is the cancer of the blood cells. There is no known cause of the disease, but risk factors include exposure to radiation. Acute leukemias are easier to diagnose because they are more likely to have symptoms, while chronic leukemias are often diagnosed late because they don’t often present any signs.


Patients with leukemia are more susceptible to anemia, infections, unexplained fevers, and bleeding (including nosebleeds).


Chronic Liver Disease

Chronic liver disease or Cirrhosis is a disorder in which the liver eventually stops working due to scar tissue gradually replacing all the healthy liver tissue. It’s usually caused by hepatitis, alcohol abuse, and autoimmune disorders.


Jaundice, easy bruising, vomiting blood, and bleeding from the esophagus or the nose are symptoms of cirrhosis.


How to Stop a Nosebleed

To stop a nosebleed, sit up straight and slightly tilt your head forward. Pinch the soft part of your nose so that it’s closed shut, and keep at it for 10 minutes.


If you are experiencing frequent nosebleeds, set an appointment with an ENT doctor immediately. For more details of our ENT services, please contact HK ENT Specialist.
