What is asbestosis primarily characterized by?

Asbestosis is primarily characterized by scarring of the lung tissue, which results from prolonged exposure to asbestos fibers. When asbestos is inhaled, the fibers can become lodged in the lung tissue, triggering an inflammatory response and leading to the development of fibrotic scars. This fibrosis reduces the lung's ability to expand and contract, ultimately impairing respiratory function.

The formation of this scar tissue differentiates asbestosis from other respiratory conditions. Unlike infections or conditions causing fluid accumulation in the lungs, asbestosis is specifically linked to the inhalation of asbestos and the resulting chronic inflammatory response and fibrosis. Understanding the nature of asbestosis is essential for recognizing its symptoms, including shortness of breath and a persistent cough, which contrast with other respiratory illnesses.
