What symptom does coal lung disease terminal period have

summary

Coal lung disease refers to long-term exposure to coal dust containing less than 5% silica, which will cause some changes in lung lesions, fibrosis and fibrous nodules in lung interstitial tissue. Coal dust is one of the main factors of this disease. Long term exposure to coal dust will not only cause coal worker pneumoconiosis, but also increase the incidence rate of chronic obstructive pulmonary disease, and oxidative stress injury will play a very important role in the pathogenesis of coal worker's pneumoconiosis and COPD. Alveolar macrophages in the process of phagocytosis of dust, will produce a large number of reactive oxygen species, and will release a variety of proteases and inflammation. Next, let's talk about the symptoms of this disease. I hope you can prevent it early.
