Disease Analysis: Chronic Obstructive Pulmonary Disease (COPD)

Chronic obstructive pulmonary disease (COPD) is defined by persistent airflow limitation (reduction in the ability to exhale at a normal rate and volume). While chronic and progressive dyspnea (shortness of breath) is a key symptom, patients may also present with productive cough. Significant exposure to noxious particles or gases, namely tobacco smoke, is the primary cause of the underlying alveolar and airway abnormalities that result in the airflow limitation and respiratory symptoms that characterize the disease.
