Hello! My father suffers from chronic bronchitis. He used to work under very difficult condition in a factory of concrete. He retired three years ago because of his health condition. He is under corticosteroid treatment for the first time and still has no side effects although his doctor told us they are possible. I would like to know what causes chronic bronchitis.

Hello! The main cause of chronic bronchitis is cigarette smoking. Tobacco smoke, when inhaled into the lungs, irritates the airways and as a result they produce mucus. You made a good connection between your father’s work environment since people who have been exposed to irritants in a long period of time, such as chemical fumes, dust and other substances, can also get chronic bronchitis.
