Asbestosis is a term used to describe chronic, progressive inflammation of the lungs, an illness directly linked to the inhalation of asbestos fibers. Asbestos is a mineral comprised of durable, microscopic fibers that are extremely toxic to one's health.
Wide use of asbestos
Because of its durability and resistance to heat, asbestos has been used in various applications. The use of asbestos was not regulated until the 1970s, after it had already been used extensively in buildings and countless workplaces. Consequently, many people had already been exposed to asbestos without knowing of its harmful effects.
How asbestosis develops
If damaged or disturbed, asbestos separates into loose fibers that can be easily inhaled. Once inhaled, the fibers penetrate the breathing passages and can settle into the lungs, where they will eventually irritate and scar the lung tissue. This can lead to the development of asbestosis.
Who is at risk of developing asbestosis?
Individuals who work with high levels of asbestos on a daily basis are at the highest risk of developing asbestosis; however, even the smallest amount of asbestos exposure can be harmful. Individuals who live near asbestos manufacturing plants are also at risk of asbestosis.
Symptoms of asbestosis:
Symptoms of asbestosis usually do not appear until 15-20 years after initial exposure to asbestos. The first sign of asbestosis is usually shortness of breath after exercise or other forms of physical activity. Excessive coughing and an overall feeling of illness and fatigue are also common symptoms in individuals during the early stages of asbestosis. Following is a list of other symptoms common to advanced asbestosis:
Asbestosis cannot be cured, but its symptoms can be controlled. Ultrasonic, cool-mist humidifiers or controlled coughing can loosen bronchial secretions, making it easier for patients to breathe and sleep. Regular exercise is proven to maintain and improve lung capability, although some patients with advanced asbestosis may be advised to stay on bed rest.
