Intro
FAQ: What is it?
Chronic Obstructive Pulmonary Disease is a progressive, irreversible restriction of breathing. In COPD the lungs become abnormally inflamed, leading to coughing, chronic breathlessness and sputum production. Smoking is by far the most common cause, followed by exposure to dusts, chemicals or air pollution. Bacterial infection in the lungs commonly leads to acute episodes.
