Patients with chronic rhinitis can donate blood. Overall, chronic rhinitis primarily causes inflammation of the nasal mucosa or inferior turbinates, and it does not greatly affect overall health, mainly presenting with localized symptoms in the nose such as nasal congestion, runny nose, and sneezing. Generally, it does not directly impact the blood. Before donating blood, it is possible to conduct some related blood tests to check for other diseases. If the criteria are met, one can normally donate blood. Therefore, there are no contraindications for blood donation in patients with chronic rhinitis, as long as they meet the requirements. Moreover, donating blood to a certain extent is actually beneficial for health.
