What Causes Nosebleeds?
4. Allergies
Allergies can be very uncomfortable and can cause the nasal lining to become inflamed and irritated. This, in turn, can result in a nosebleed, especially considering the patient is also likely to be blowing their nose regularly. The same problems can happen when the nasal lining is irritated because of the common cold.
Non-allergic rhinitis is another condition that will sometimes lead to nosebleeds. This is a condition where the patient’s nasal lining is more sensitive than usual, causing it to become irritated and inflamed easily. Treatments for these conditions, such a nasal sprays, will also sometimes result in a nosebleed.
