Recurring nosebleeds can happen for a number of reasons. Here's a breakdown of the most common causes:
-
Underlying Medical Conditions:
- High Blood Pressure (Hypertension): Elevated blood pressure can put increased pressure on the delicate blood vessels in your nose, making them more prone to rupture and bleed.
- Bleeding Disorders: Conditions like hemophilia or von Willebrand disease impair blood clotting, leading to prolonged and repeated nosebleeds.
- Tumors: In rare cases, a tumor in the nasal cavity or sinuses can cause recurrent nosebleeds.
-
Medications:
- Blood Thinners: Medications such as warfarin (Coumadin), clopidogrel (Plavix), and even aspirin can interfere with blood clotting and increase the risk of nosebleeds. Talk to your doctor if you're on these medications and experiencing frequent nosebleeds; they may be able to adjust your dosage or suggest alternatives.
-
Environmental Factors:
- Dry Air: Dry air, especially during winter months or in dry climates, can dry out the nasal passages and make them more susceptible to bleeding. Using a humidifier can help.
- Nasal Irritation: Frequent nose picking, forceful nose blowing, or nasal allergies can irritate the nasal lining and lead to repeated nosebleeds.
-
Other Causes:
- Nasal Trauma: Even minor trauma to the nose, such as bumping it or rubbing it too hard, can cause bleeding.
- Nasal Decongestants: Overuse of nasal decongestant sprays can dry out the nasal passages and lead to rebound congestion and nosebleeds.
- Deviated Septum: A deviated septum (a displacement of the cartilage that divides the nostrils) can sometimes make one nostril more prone to nosebleeds.
If you experience frequent or severe nosebleeds, it's essential to consult a doctor or ENT specialist to determine the underlying cause and receive appropriate treatment. They can assess your medical history, perform a physical examination, and order any necessary tests.
