Asbestosis

Asbestosis is a nonmalignant lung disease caused by inhalation of asbestos dust.  When someone is exposed to asbestos for a prolonged period, he or she will breathe in millions of tiny asbestos fibers.  Over time, these microscopic fibers become lodged in the lung tissue.

Because these fibers are so long and sharp, the body’s normal defenses are unable to eliminate them.  The asbestos fibers remain in the lungs, and cause inflammation and scarring in the alveoli. Over time, the scar tissue accumulates.  This is a condition known as pulmonary fibrosis, which makes it impossible for the lungs to function properly.  The lungs become stiff, and can no longer expand and contract normally.  In addition, the damaged lung tissue loses its ability to transfer oxygen into the bloodstream.

As the disease progresses, lung capacity diminishes, and the patient finds it increasingly difficult to catch his or her breath.  Besides experiencing shortness of breath or dypsnea, the patient may also have other symptoms such as coughing, chest pain, tightness in the chest, and abnormal growths or clubbing of the fingers.

Asbestosis is a disease that worsens over time. In its advanced stages, it is a disabling condition, and can even be fatal.  Like mesothelioma, asbestosis has a long latency period.  Typically, symptoms do not appear for at least 15 to 20 years after the first exposure to asbestos.

If you are diagnosed with asbestosis, it is very important that you stop smoking immediately.  Asbestosis puts you at heightened risk for lung cancer and mesothelioma, so be sure that you visit your doctor for regular check-ups.  You should also be sure to get regular chest x-rays to monitor the condition of your lungs.
