What are the common causes of sinusitis?

Sinusitis, a common condition that causes inflammation of the sinuses, can be attributed to a variety of factors. Infections, such as colds or the flu, are among the most common causes of sinusitis. When these respiratory infections occur, the sinuses can become congested and blocked, leading to inflammation. Allergies are another prevalent cause, as they trigger an immune response that results in swelling and congestion of the sinus tissue. Structural abnormalities, such as a deviated septum or nasal polyps, can also contribute to sinusitis by obstructing the nasal passages. Additionally, environmental irritants like tobacco smoke or pollutants can irritate the sinuses and lead to infection or inflammation. Overall, sinusitis is often a result of various factors working together to compromise the normal functioning of the sinuses.
