What Is Nasal Discharge?

Nasal discharge refers to mucus or fluid released from the nasal passages. It is produced by the lining of the nose to trap dust, allergens, and germs, helping protect the respiratory system.

Normally, a small amount of mucus is produced and swallowed without notice. However, when production increases due to infection or irritation, it leads to noticeable nasal discharge.
