Cause of COPD
COPD is characterized by thickening of the airways and limitation to airflow. People with COPD have trouble breathing and shortness of breath. . It is stated by the Global Initiative for Chronic Obstructive Lung Disease as “a preventable and treatable disease.. characterized by airflow limitation that is not fully reversible”. The primary cause of COPD is smoking; tobacco smoke, marijuana, cigar and water pipe smoke. The risk of COPD increases in child when women smoke during pregnancy. Serious and delayed introduction to workplace dust, chemicals and fumes increment the danger of COPD in both smokers and nonsmokers. Sometimes, a genetic condition called alpha-1 antitrypsin deficiency may play a role in causing COPD. People have low levels of alpha-1 antitrypsin (AAT); a protein made in the liver, can have this disease.
