What diseases could cause bloody nasal discharge?

This phenomenon is not uncommon in daily life, but when patients repeatedly experience nosebleeds, it often causes significant concern. What diseases could be indicated by bloody nasal discharge?

What Diseases Can Cause Bloody Nasal Discharge?

Causes of bloody nasal discharge include the following: Dry nasal mucosa: Mucosal erosion can lead to blood-tinged nasal mucus, which typically appears as streaks of blood within the mucus—either bright red or dark red. Occasionally, if the bleeding is heavy or involves old blood crusts and clots, more significant blood may be present. Deviated nasal septum: Especially when there is a sharp bony spur, the mucosa is prone to rupture, resulting in blood streaks. New growths in the nasal cavity: These may be benign or malignant tumors. When the mucosa over the tumor breaks down, bleeding occurs, leading to blood-tinged or bloody nasal discharge.

Benign tumors commonly include papillomas, while malignant ones include cancers of the nasal cavity, paranasal sinuses, or other tumors that may present with bloody nasal discharge. Nasopharyngeal conditions: Tumors in the nasopharynx caused by neoplasms such as hemangiomas may rupture and lead to epistaxis or bloody nasal discharge.

Firstly, dry rhinitis should be considered. Patients with this condition mainly suffer from dryness in the nasal cavity, local mucosal erosion, ulceration, and minor bleeding from small blood vessels. Clinically, nasal endoscopy is recommended to rule out other diseases. For treatment, doctors may prescribe compound menthol nasal drops or recommend rinsing the nasal cavity with medical-grade physiological saline. Common nasal tumors such as inverted papilloma, hemorrhagic nasal polyps, maxillary sinus cancer, and ethmoid sinus cancer may also present with symptoms like bloody nasal discharge.
