What are the common causes of epistaxis?
• The most common cause is what we called idiopathic due to rupture of blood vessels in the nose as a result of minor trauma during nose blowing, rubbing, pricking and sneezing. • Other more definite trauma to the nose such as a blow or a fall with nose hitting against object can obviously results in epistaxis. • Tumour of the nose or nasopharynx is also a common cause. • Epistaxis is also commonly seen in patient with bleeding tendency e.g. platelet insufficiency.
