Chronic obstructive pulmonary disease (COPD) is a heterogeneous lung condition characterized by chronic respiratory symptoms, including dyspnea, cough, and sputum production. These symptoms result from airway abnormalities, such as bronchitis or bronchiolitis, and/or alveolar abnormalities, such as emphysema, that cause persistent and often progressive airflow obstruction.
