A constantly blocked nose can stem from various causes, ranging from common infections to underlying structural issues. Let's explore some of the key reasons.
Common Causes of Nasal Congestion
-
Infections: Colds, the flu, and sinusitis (infection of the sinuses) are frequent culprits. These infections inflame the nasal passages, leading to congestion. Anything that irritates the inside of the nose can cause a stuffy nose. (Reference: Provided Text)
-
Allergies: Allergic rhinitis is a common condition triggered by allergens like pollen, dust mites, or pet dander. This causes inflammation and swelling in the nasal lining, resulting in a blocked nose. The uncomfortable, plugged feeling is common with colds and allergies. (Reference: Mayo Clinic Health System)
-
Irritants: Exposure to environmental irritants such as tobacco smoke, perfume, dust, and car exhaust can irritate the nasal passages, causing congestion.
-
Nasal Polyps: These noncancerous growths in the nasal passages can obstruct airflow, leading to a persistently blocked nose. If symptoms don't improve, they may be linked to nasal polyps, which cause nasal congestion and a runny nose. (Reference: Johns Hopkins Medicine)
-
Non-Allergic Rhinitis: This condition involves nasal irritation without an allergic reaction. It causes a blocked or runny nose due to irritation within the nose. (Reference: NHS)
Less Common but Significant Causes
-
Deviated Septum: A deviated septum, where the cartilage dividing the nostrils is misaligned, can partially block one or both nasal passages. This often results in one side being more consistently blocked than the other. (Reference: Verywell Health, Houston Sinus Surgery) Patients frequently complain of one side always being blocked, often due to structural issues. (Reference: Atlantic ENT Associates)
-
Chronic Sinusitis: This condition involves prolonged inflammation of the sinuses, lasting 12 weeks or more, even with treatment. It prevents proper mucus drainage, leading to persistent stuffiness. (Reference: Mayo Clinic) Chronic sinusitis is more than just a stuffy nose. (Reference: Mayo Clinic Health System)
Identifying and Addressing the Issue
Determining the underlying cause of your blocked nose requires a proper diagnosis. A doctor can assess your symptoms, conduct a physical examination, and possibly order further tests to pinpoint the problem. Treatment will vary depending on the cause, ranging from over-the-counter medications for allergies or colds to surgery for a deviated septum or nasal polyps. Chronic stuffiness could be rhinitis, a condition with additional symptoms like sneezing and reduced sense of smell. (Reference: UCLA Health)
