Chronic Obstructive Pulmonary Disease (COPD) is a chronic lung disorder characterized by airflow obstruction that does not change markedly over time. The obstruction is caused by emphysema, chronic bronchitis, or both. Emphysema involves destruction of lung tissue, while chronic bronchitis involves inflammation of the airways accompanied by mucus hypersecretion. Symptoms include cough, sputum production, wheezing and shortness of breath. Diagnosis is based on patient history, symptoms, and lung function tests showing airflow obstruction. Management involves reducing risk factors, treating stable disease and exacerbations, and rehabilitation.
