What is a runny nose?
A runny nose, also known as rhinorrhea, is a common symptom characterized by the discharge of mucus from the nostrils. The mucus can range in consistency from thin and clear to thick and yellow-green, and the color can be a clue to the underlying cause.
Causes of a runny nose:
Infections:
This is the most common cause of a runny nose. Viral infections, such as the common cold or the flu, can cause inflammation and excess mucus production in the nose. Bacterial infections, such as sinusitis, can also cause a runny nose.
- Allergies:
Allergies occur when the immune system overreacts to a harmless substance, such as pollen, dust, or pet dander. This reaction can cause the release of histamine, a chemical that leads to inflammation and mucus production in the nose.
- Irritants:
Inhaling irritants, such as smoke, dust, or chemicals, can cause the lining of the nose to become inflamed and produce excess mucus.
- Nonallergic rhinitis:
This is a condition characterized by chronic inflammation of the nose, which can lead to a runny nose. The exact cause of nonallergic rhinitis is unknown, but it may be linked to factors such as stress, hormonal changes, or weather changes.
- Decongestant overuse:
Decongestant nasal sprays can be helpful for relieving a runny nose, but using them for too long can actually make the problem worse. This is known as rebound congestion.
Other medical conditions: Some less common medical conditions, such as a deviated septum or tumors in the nose, can also cause a runny nose.
Symptoms of a runny nose:
- Discharge of mucus from the nose.
- Stuffy nose.
- Postnasal drip.
- Sneezing.
- Itchy nose.
- Coughing.
- Sore throat.
Treatment for a runny nose:
The treatment for a runny nose will depend on the underlying cause. For most people, a runny nose will go away on its own within a few days. However, there are some things you can do to relieve the symptoms, such as:
- Get plenty of rest.
- Drink plenty of fluids.
- Use a saline nasal spray or drops.
- Take over-the-counter medications, such as decongestants or antihistamines.
- Apply a warm compress to your nose.
- Use a humidifier to add moisture to the air.
If your runny nose is severe or does not improve after a week, see your doctor. They can help you determine the underlying cause and recommend the best course of treatment.
