What lung diseases can long-term inhalation of dust cause?

Long-term inhalation of dust can lead to various lung diseases, the most common of which are respiratory inflammation and chronic bronchitis. This occurs because tiny particles in dust enter the respiratory tract, irritating and damaging the mucous membranes, thereby triggering inflammatory responses. Over time, these inflammatory reactions gradually develop into chronic bronchitis, restricting airflow in the airways and causing symptoms such as coughing, sputum production, and wheezing. Additionally, prolonged dust exposure can result in pulmonary fibrosis—scarring of lung tissue due to damage—which impairs lung function and leads to symptoms like shortness of breath and dyspnea. Severe pulmonary fibrosis may further cause serious complications such as cor pulmonale and pulmonary hypertension. Moreover, long-term dust inhalation increases the risk of developing lung cancer.
