Asbestosis
Asbestosis is a chronic inflammation of the delicate tissue in the lungs caused by inhaling asbestos fibers. It is usually the result of extreme or long-term exposure to asbestos from occupations involving the manufacturing, handling or removal of asbestos. Symptoms include severe shortness of breath, and the condition increases ones risk for lung cancer and mesothelioma.
The symptoms of asbestosis generally do not appear until long after first exposure, even decades later. The main symptom of asbestosis is shortness of breath, especially during periods of exertion, which progresses slowly over time. Extreme cases of asbestosis can sometimes lead to respiratory failure.
Asbestosis is caused by inflammation and scarring of lung tissue (around terminal bronchioles and alveolar ducts) from inhaling asbestos fibers. This scarring can restrict (due to stiffening) and/or obstruct lung functioning. In some severe cases, the dramatically decreased lung functioning can cause partial heart failure, or other serious effects.
There is no cure for asbestosis, but oxygen therapy is often used to correct hypoxia (insufficient oxygen) and to relieve the shortness of breath. In addition, nebulizers and respiratory physiotherapy may be used to loosen or remove secretions or treat underlying Chronic Obstructive Pulmonary Disease. Patients may be immunized against bacterial pneumonia and influenza due to increased vulnerability to the diseases. Patients are at increased risk for certain malignancies most notably mesothelioma and lung cancer. Quitting smoking reduces further damage.
