🩺 What Is a Runny Nose?
A runny nose (rhinorrhea) refers to the flow of nasal secretions from the nostrils. It occurs when the nasal mucosa produces excess mucus due to environmental factors, irritation, or medical conditions. The discharge may be watery, thick, or contain mucus and other components depending on the cause.
🔍 Common Causes
A runny nose can result from various physiological or pathological factors, including:
-
Environmental changes – Exposure to cold air or irritants may increase nasal secretion.
-
Common cold (viral infection) – Viral inflammation of the nasal mucosa is a frequent cause.
-
Allergic rhinitis – Triggered by allergens such as pollen, dust, or pet dander.
-
Sinus inflammation – Swelling in the sinus cavities can lead to mucus overflow.
-
Nasal polyps or structural issues – May block airflow and cause mucus buildup.
-
Other causes – Crying, hormonal changes, or foreign bodies in the nose can also contribute.
⚠️ Related Symptoms
Depending on the underlying cause, a runny nose may accompany:
-
Sneezing
-
Nasal congestion
-
Itchy or irritated nose
-
Headache or facial pressure
-
Mild cough or throat irritation
🧠 When to Seek Medical Advice
While a runny nose is often temporary, professional evaluation is recommended if you experience:
-
Persistent nasal discharge lasting more than 10–14 days
-
Yellow-green or foul-smelling mucus
-
Repeated nosebleeds or blood-tinged discharge
-
Accompanying fever, facial pain, or breathing difficulty
-
Clear, watery fluid following head injury (possible cerebrospinal fluid leakage)
If symptoms persist or worsen, consider consulting an ENT (Ear, Nose & Throat) specialist or a general physician for assessment.
Summary
A runny nose is a common condition caused by multiple factors, from weather changes to allergic or infectious triggers. Most cases are mild and self-limited. Understanding your symptoms and potential causes helps determine when professional evaluation is appropriate.
