Definition: The definition of COPD is one that describes a lung disease that is preventable and treatable, but for which there is no cure. COPD, or chronic obstructive lung disease, is characterized by obstruction of the airways and limitation of airflow both into and out of the lungs. The airflow limitation is usually progressive (gets worse with time) and associated with an abnormal inflammatory response of the lungs to noxious particles or gases such as tobacco smoke, secondhand smoke, air pollution or harsh chemicals in the workplace.
There are three types of COPD, including emphysema, chronic bronchitis and bronchiectasis.
