During the colder months with the return of school, many individuals experience symptoms like a cough, runny, or blocked nose due to common colds or flu. These conditions can persist for weeks, making it challenging to decide when to seek medical advice. Dr. Sina Joorabchi, an Ear, Nose, and Throat specialist, shared insights on interpreting the colors of nasal discharge to determine when to consult a healthcare provider.

Clear mucus is usually considered normal and healthy, unless it is excessive, which may indicate allergy issues. The NHS notes that clear mucus serves to moisturize and protect nasal passages. White mucus can suggest dehydration or an early viral infection, while thick white mucus might be a sign of a bacterial infection requiring attention.

Yellow or green mucus can point to infections like colds, flu, or chest infections. Dr. Sina highlighted that green mucus is commonly associated with bacterial infections but could also occur in prolonged viral infections. While green mucus may resolve naturally in a few weeks, persistent symptoms warrant a doctor’s evaluation.

Dr. Sina advised caution with green mucus, suggesting observation for accompanying symptoms like fever or persistent cold symptoms. If symptoms persist or worsen, seeking medical advice is recommended. It is essential to consult a doctor if colored mucus persists beyond a few weeks or if there are concerns about the symptoms.
