Rhinorrhea
Rhinorrhea, more commonly referred to as a runny nose, is an excess drainage produced by nasal and adjacent tissues and blood vessels in the nose. This drainage can range from a clear fluid to thick mucus and can run out of your nose, down the back of your throat or both.
Causes[edit | edit source]
- The most common causes of rhinorrhea include:
- Common cold: This viral infection of your upper respiratory tract is the most common cause of a runny nose.
- Allergies: Many people have rhinorrhea when they're exposed to common allergens such as dust mites, pet dander, pollen, or mold.
- Sinusitis: This inflammation of the sinuses often follows a cold and can cause postnasal drip.
- Flu (Influenza): Rhinorrhea is a common symptom of the flu.
Symptoms[edit | edit source]
In addition to a runny nose, rhinorrhea may be accompanied by sneezing, itchy or watery eyes, sinus pressure, and sore throat.
Treatment[edit | edit source]
Treatment for rhinorrhea depends on its cause. For a runny nose caused by a virus, rest, warm liquids, and over-the-counter cold remedies can help. If an allergy is causing rhinorrhea, antihistamines, nasal steroid sprays, or desensitization therapy (allergy shots) may be recommended.
Prevention[edit | edit source]
Prevention strategies can include hand hygiene to prevent infection, avoiding allergens, and using a humidifier to keep nasal and throat passages moist.
