Frequent nosebleeds can occur when the tiny blood vessels inside the nose become irritated, damaged, or overly dry. Common causes include dry weather, allergies, repeated nose picking, sinus infections, trauma, smoking, blood thinning medications, and vitamin deficiencies. In some cases, high blood pressure or bleeding disorders may lead to persistent nosebleeds. Environmental irritants like pollution and strong chemical fumes can also worsen nasal sensitivity. Identifying the trigger early helps prevent future bleeding and complications. Medicover Hospitals provides expert ENT evaluation, nasal endoscopy, and targeted treatment to diagnose the root cause and restore nasal health effectively.
