A runny nose, also known as rhinorrhea, is a common symptom that can be caused by a variety of factors, including allergies, colds, sinus infections, and environmental irritants. The medical term for a runny nose is rhinorrhea, which is derived from the Greek words "rhinos" meaning nose and "rhoia" meaning flow.
Rhinorrhea can manifest in different forms, including clear and watery discharge, thick and yellow or greenish discharge, or even bloody discharge in severe cases. Understanding the underlying cause of rhinorrhea is crucial in determining the best course of treatment and finding relief.
Causes of Rhinorrhea
Rhinorrhea can be caused by a range of factors, including:
- Allergies: Allergic reactions to pollen, dust, mold, or pet dander can trigger rhinorrhea.
- Upper respiratory infections: Colds, flu, and sinus infections can cause rhinorrhea.
- Environmental irritants: Exposure to pollution, tobacco smoke, and strong odors can irritate the nasal passages and lead to rhinorrhea.
- Anatomical issues: Deviated septum, nasal polyps, or enlarged turbinates can obstruct nasal passages and cause rhinorrhea.
Allergic Rhinorrhea
Allergic rhinorrhea, also known as allergic rhinitis, is a common condition that affects millions of people worldwide. It occurs when the immune system overreacts to harmless substances like pollen, dust, or mold, leading to inflammation and increased mucus production in the nasal passages.
The symptoms of allergic rhinorrhea include:
- Rhinorrhea
- Sneezing
- Nasal congestion
- Itchy nose, eyes, and throat
Infectious Rhinorrhea
Infectious rhinorrhea, on the other hand, is caused by viral or bacterial infections that affect the upper respiratory tract. The common cold and flu are two of the most common causes of infectious rhinorrhea.
The symptoms of infectious rhinorrhea include:
- Rhinorrhea
- Coughing
- Sore throat
- Fever
- Fatigue
