High blood pressure can cause nosebleed?

High blood pressure may cause epistaxis, but epistaxis is not a specific manifestation of hypertension.

Hypertension patients in poor blood pressure control, because the blood pressure significantly increased, can lead to increased blood perfusion in the head and face, and then cause pressure on blood vessels, and nasal mucosa itself is relatively fragile, in this larger pressure, may rupture, resulting in epistaxis. However, there are many causes of epistaxis, in addition to hypertension, but also in acute rhinitis, atrophic rhinitis and nasal septum deviation and other diseases. Therefore, it is impossible to judge whether the symptoms of nosebleed are related to hypertension.
