Epistaxis-causes
Systemic causes -
- Hypertension - There is relationship between hypertension and epistaxis . In adults epistaxis is more common in hypertensive patients, and patients are more likely to be acutely hypertensive during an episode of epistaxis. Hypertension, however, is rarely a direct cause of epistaxis, and therapy should be focused on controlling hemorrhage before blood pressure reduction.
- Vascular abnormalities - like sclerosed vessels, A-V malformations, hereditary haemorrhagic telengeactasia
- Bleeding tendencies - thrombocytopenia, liver disease, coagulopathies.
- Systemic infections such as AIDS,typhoid, pneumonia, malaria, dengue fever, measles etc.
- Pregnancy
- Menstruation (vecarious menstruation)
