What is pneumoconiosis, how is pneumoconiosis caused and how to prevent pneumoconiosis?

Pneumoconiosis, also known as pneumoconiosis, is an occupational disease. It is more common in patients who have not taken appropriate protective measures at work and inhaled productive dust for a long time. After entering the respiratory tract, dust accumulates in the terminal bronchi and alveoli, forming a barrier layer, which will affect the gas exchange between alveoli and the outside world when breathing. Long-term pneumoconiosis patients, if not treated, will further lead to right ventricular hypertrophy, pulmonary heart disease and so on. Long-term pneumoconiosis can also induce lung cancer, emphysema and other diseases. Mild symptoms include cough and expectoration, while severe symptoms can lead to dyspnea, chest tightness and chest pain. Therefore, it is suggested that workers who have been exposed to dust for a long time must be well protected and wear masks or masks. Patients with pulmonary fibrosis and severe decline in lung function need active treatment and surgery if necessary.
