Rhinorrhea
Rhinorrhea
Rhinorrhea (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 can be a result of inflammation and excessive mucus production in the nasal passages.
Etymology
The term "Rhinorrhea" is derived from the Greek words "rhinos" meaning "nose" and "rhoia" meaning "flow" or "discharge".
Causes
Rhinorrhea can be caused by several factors, including:
- Allergies: This is one of the most common causes of rhinorrhea. It occurs when the body's immune system overreacts to allergens in the environment, such as dust, pollen, or pet dander.
- Common cold: This is a viral infection of the upper respiratory tract that can cause rhinorrhea, among other symptoms.
- Influenza: Also known as the flu, this is another viral infection that can cause rhinorrhea.
- Sinusitis: This is an inflammation or swelling of the tissue lining the sinuses, which can result in rhinorrhea.
- Non-allergic rhinitis: This is a type of chronic rhinorrhea that is not caused by allergies.
Treatment
Treatment for rhinorrhea depends on its cause. For instance, rhinorrhea caused by allergies may be treated with antihistamines, while rhinorrhea caused by a bacterial infection may require antibiotics. In some cases, decongestants may be used to relieve the symptom.
Related Terms
- Nasal congestion: This is a symptom often associated with rhinorrhea, characterized by a blocked or stuffy nose.
- Post-nasal drip: This is a condition where excess mucus from the nose drips down the back of the throat, often accompanying rhinorrhea.
- Sneezing: This is a reflex action often triggered by irritation in the nose, which can be caused by rhinorrhea.
