Rhinorrhoea
Rhinorrhoea
Rhinorrhoea (pronounced: rye-no-ree-uh), also known as a runny nose, is a common symptom of allergies or certain diseases, such as the common cold or influenza. It occurs when an excess of nasal mucus is produced by the nasal mucosa.
Etymology
The term "rhinorrhoea" comes from the Greek words "rhinos" meaning "nose" and "rhoia" meaning "flow" or "discharge".
Causes
Rhinorrhoea can be caused by several factors, including:
- Allergies: This is the most common cause of rhinorrhoea. Allergens such as pollen, dust, and pet dander can trigger the body's immune response, leading to the production of mucus.
- Infections: Viral infections like the common cold or influenza can cause rhinorrhoea. Bacterial infections can also lead to a runny nose, though this is less common.
- Irritants: Exposure to certain irritants, such as smoke, strong odors, or cold air, can cause rhinorrhoea.
Treatment
Treatment for rhinorrhoea depends on the underlying cause. For allergies, antihistamines or nasal sprays may be used. If the cause is a viral infection, the symptoms usually resolve on their own within a week or two. However, over-the-counter cold remedies can help alleviate the symptoms.
Related Terms
- Nasal congestion: This is often associated with rhinorrhoea. It occurs when the nasal tissues and blood vessels become swollen with excess fluid, causing a "stuffy" feeling.
- Post-nasal drip: This occurs when excess mucus from the nose goes down the throat, often causing a cough or sore throat.
- Sinusitis: This is an inflammation of the sinuses that can cause symptoms similar to rhinorrhoea.
