Causes of inflammatory lung diseases include smoking, asbestos, and air pollution and irritants, according to the Office of Women's Health. Inflammatory lung diseases include asthma, chronic obstructive pulmonary disorder and sarcoidosis. The exact causes of asthma and sarcoidosis are unknown; however, these diseases are believed to be caused by a combination of genetic predisposition and environmental triggers, explains Mayo Clinic.
The main cause of chronic obstructive pulmonary disease, also known as COPD, is cigarette smoking. COPD refers to a condition involving chronic obstructive bronchitis and emphysema, reports the Office of Women's Health. One important feature of COPD is inflammation of bronchial tubes, which can make breathing very difficult.
Triggers that are associated with asthma include airborne allergens and pollutants, respiratory infections, physical activity, stress, certain medications, and gastroesophageal reflux disease, according to Mayo Clinic.
Sarcoidosis is an inflammatory lung disease that may be caused by both genetics and exposure to trigger such as bacteria, viruses, dust or chemicals, explains Mayo Clinic.
Asbestosis is lung disease caused by the inhalation of asbestos fibers, according to Asbestos Network. When asbestos becomes trapped in the alveoli of the lungs, this triggers an inflammatory process by the immune system to remove this irritant, which leads to scarring and difficulty breathing.
