Question: I recently started having bloody noses for seemingly no reason. I’m otherwise in good health, although my blood pressure is a little high. What could be the cause?

Dr. Hibberd's answer:
Nosebleeds can occur spontaneously when the nasal membranes dry out and crack. This is common in dry climates, or during the winter months when the air is dry and warm from household heaters. People are more susceptible to a bloody nose if they are taking medications which prevent normal blood clotting warfarin (Coumadin), aspirin, or any anti-inflammatory medication. In this situation, even a minor trauma, like nose picking could result in significant bleeding. Other common causes of nosebleeds include sinusitis, common cold, and allergies. Even though some experts cite hypertension as a cause of nose bleeds, others don’t agree. However, do not ignore your high blood pressure, please consult with your doctor the likely cause of nosebleed and seek advice for high blood pressure.
