Can rhinitis cause bloody nasal discharge?

Generally, rhinitis can cause bloody nasal discharge. The specific analysis is as follows:

First, the inflammation of nasal mucosa caused by rhinitis may lead to increased or decreased secretion of nasal mucus, making the nasal mucosa dry. When the mucosa becomes dry, small blood vessels are prone to rupture, resulting in blood-tinged nasal discharge. Second, inflammation and congestion of the nasal mucosa due to rhinitis increase the fragility of nasal blood vessels. When the mucosa is excessively stimulated or inflamed, these vessels are more likely to break, causing blood to appear in nasal discharge. Nasal obstruction and stuffiness caused by rhinitis may prompt patients to blow their nose forcefully, which could rupture surface blood vessels in the nasal mucosa and lead to bloody mucus. Additionally, rhinitis is often associated with sinusitis. When the sinuses become inflamed, the mucosal lining may swell and become damaged, potentially leading to streaks of blood in the nasal discharge.

If bloody nasal discharge occurs frequently, or if the bleeding is heavy or prolonged, it is advisable to consult a doctor for evaluation and diagnosis.
