Epistaxis is very common and usually stops quickly without medical treatment. The majority (80%) arise from the front part of the nasal septum (Little’s area), where several small arteries converging from various directions end. A nose injury, URTI, drying and crusting due to drugs, chemotherapy or CPAP usage, vigorous blowing or picking are the main causes. About 20% come from arteries further back in the nose and tend to occur in men over 60 years of age with high blood pressure (hypertension) and hardening of the arteries (arteriosclerosis). Nasal tumours often cause bleeding but are fortunately rare. Medical conditions affecting blood clotting (coagulation) and drugs to thin the blood (anti-coagulants) are also predisposing factors.
