==Overview==
==Overview==
The [[causes]] of [[epistaxis]] can be divided into [[idiopathic]] and [[non-idiopathic]] ones. There are many [[diseases]] and medications that can cause [[epistaxis]] but it also may be spontaneous. Usually [[epistaxis]] is not dangerous but in some cases it can become [[life threatening]]. [[Trauma]] is the most common [[Causes|cause]] of [[epistaxis]].

There is not enough evidence that [[hypertension]] is a [[risk factor]] for [[epistaxis]].The role of lowering [[blood pressure]] to control and prevent [[epistaxis]] remains controversial.
 
In the table below different causes of epistaxis are classified based on organ system.

Overview

The causes of epistaxis can be divided into idiopathic and non-idiopathic ones. There are many diseases and medications that can cause epistaxis but it also may be spontaneous. Usually epistaxis is not dangerous but in some cases it can become life threatening. Trauma is the most common cause of epistaxis.

Common Causes

Less Common Causes

There is not enough evidence that hypertension is a risk factor for epistaxis.The role of lowering blood pressure to control and prevent epistaxis remains controversial.

In the table below different causes of epistaxis are classified based on organ system.
