Are Nosebleeds Hereditary ?

Nosebleeds affect many people. Embarrassing, they may in some cases be hereditary, but this is quite rare.

The Most Common Causes of Nosebleeds


A common cold, sinusitis, or rhinitis (that is to say, an inflammation of the nose) may be the source of a nosebleed.

The presence of a foreign object

Some children may amuse themselves by sticking foreign objects up their nostrils, such as toys, rocks, shells, pieces of wood, etc. These often go unnoticed for several days or even several weeks before causing an infection or inflammation. In such cases, the flow is accompanied by pus and a rather nauseating smell.

A Dry Nasal Mucosa

An overly dry environment can cause the mucous membrane in the nose to dry out. A nosebleed may therefore occur on a trip, in a very dry area, or – more commonly – in a dry room heated by electrical appliances, for example.


A blow, a fracture, bruises, or sticking your fingers up your nose are all injuries likely to cause the internal walls of the nose to bleed.

Taking anticoagulants

Certain medications, such as aspirin and nonsteroidal anti-inflammatories, can cause blood to flow from the nose. Don’t hesitate to read the labels on your medications carefully if you’re prone to nosebleeds.

High blood pressure

Rare among people under 50 years of age, high blood pressure can create nosebleeds that are difficult to stop.


Nasal polyps are benign tumours that are accompanied by a loss of the sense of smell, sinusitis, mucus discharge, and an obstruction of the nasal passages.

Rarer Causes of Nosebleeds

Nasal cancer

When the nosebleed is associated with pain in the teeth, sometimes a change in the volume of the eyes, the appearance of ganglia, and an obstruction of the nose, it’s best to consult a doctor quickly. However, it should be noted that an isolated nosebleed is in no way a significant symptom of nasal cancer.


Thrombocytopenia results in a decrease in the number of blood platelets, which can cause nosebleeds.

Hereditary coagulopathy

This hereditary condition affects the body’s blood-clotting abilities.

Osler-Weber-Rendu syndrome

This syndrome – also known as hereditary haemorrhagic angiomatosis or hereditary haemorrhagic telangiectasia – is transmitted if one of the two parents has a genetic anomaly. The flows occur starting from a very early age and continue throughout life. Furthermore, many other symptoms (angiomas, anaemia, red colouring in the mucous membranes, etc.) appear over time, most often starting from age 25.

Nosebleeds are usually benign and non-hereditary. Stress is an important factor that may cause nosebleeds (when the blood pressure rises all of a sudden).

If you’re prone to epistaxis and the bleeding episodes are recurrent, don’t hesitate to consult a specialist to understand the source of your troubles. In the meantime, you can opt for a medicinal solution or an effective gel to stop the bleeding in a few seconds. This will let you avoid awkward situations, staining yourself, and being afraid of these particularly unpleasant moments.

Always keeping a small packet of tissues in your pocket or bag, along with a treatment to stop the bleeding, are two precautions that should be taken when you suffer from nosebleeds. Consulting a doctor will also be essential if the blood flow recurs several times per month.
