Silica Dust Lung Disease Overview

Another name for Silica Dust Lung Disease is Silicosis.

What is silicosis?
A person with silicosis has damage to the lungs, caused by years of breathing silica (quartz) dust. Silica dust is a byproduct of quarrying and processing stone. Continued inhalation of the tiny dust particles causes damage to the lungs, which worsens over time. About 1.3 to 3 million workers are exposed to silica dust in the US.

What are the symptoms of silicosis?
Initial symptoms of silicosis include cough, difficulty breathing during exertion, wheezing, fever, and weight loss. Symptoms of severe silicosis may also include increased size of the chest, difficulty breathing at rest, leg swelling (bilateral), and chest pain.

How does the doctor treat silicosis?
Treatment for silicosis includes corticosteroid medications and bronchodilator medications. Treatment for severe silicosis may also include home oxygen therapy.
