What should I do if my nasal discharge contains blood?

Blood-tinged nasal discharge is a relatively common occurrence. First and foremost, identifying the underlying cause is essential. If the blood-tinged discharge is mild and transient—such as that resulting from a recent cold, nasal mucosal vascular dilation, or other benign causes—it often resolves with treatment of the underlying condition (e.g., managing the cold or treating nasal inflammation).

However, in middle-aged and older adults, blood-tinged nasal discharge warrants prompt attention, as it may represent an early symptom of nasopharyngeal carcinoma. Therefore, if such symptoms persist for an extended period in this age group, timely medical evaluation is crucial to rule out nasopharyngeal pathology—including nasopharyngeal cancer. Additionally, dryness-induced nasal mucosal irritation can also lead to blood-tinged discharge. In such cases, increasing dietary intake of fruits and vegetables, along with topical nasal lubricants—such as menthol oil or liquid paraffin nasal drops—can help alleviate the symptom.

I would like to emphasize that, for middle-aged and older adults, unexplained blood-tinged nasal discharge must be taken seriously, and prompt medical consultation and diagnostic evaluation are strongly recommended.
