Chronic obstructive pulmonary disease, or COPD, is a long-lasting obstruction of the airways that occurs with chronic bronchitis, emphysema, or both. This obstruction of airflow is progressive in that it happens over time. Chronic bronchitis is defined as a chronic (ongoing, long-term) cough not caused by another condition that produces sputum (mucus) for 3 or more months during each of the 2 consecutive years.
