COPD causes : COPD is caused by long term exposure of the lungs to irritants and inflammation. Usually the irritant is tobacco smoke, but there can be other environmental irritants. Rarely, some have a genetic alpha-1 antitrypsin deficiency, a protein the protects the lungs among other organs. Also asthma, as a chronic inflammatory disorder, can lead to COPD in very uncommon cases.
