What medical term refers to abnormal discharge from the nose?

The term that accurately describes abnormal discharge from the nose is rhinorrhea. It derives from the Greek words "rhin" meaning nose and "rrhea" meaning flow or discharge. This condition often presents as a runny nose, which can be a symptom of a variety of medical conditions, such as allergies, infection, or irritants.

Rhinorrhagia refers to a nosebleed, which is more associated with bleeding than typical discharge. Rhinomycosis pertains to a fungal infection of the nose, and rhinoplasty is a surgical procedure for reshaping the nose, which does not relate to discharge at all. Understanding these definitions helps clarify why rhinorrhea is the most appropriate term for abnormal nasal discharge.
