Is nasal congestion a disease? Nasal congestion is not a disease in itself, but rather a symptom of an underlying condition. It occurs when the tissues lining the nasal passages become swollen and inflamed, making it difficult to breathe through the nose.
Nasal congestion can be caused by a variety of factors, including allergies, colds and flu, sinus infections, environmental irritants such as smoke or pollution, and structural issues such as deviated septum.
In some cases, nasal congestion can be a symptom of a more serious condition, such as nasal polyps or tumors. If you are experiencing persistent nasal congestion, it is important to see a healthcare provider to determine the underlying cause and receive appropriate treatment.
