Interstitial fibrosis generally refers to pulmonary fibrosis. Pulmonary fibrosis is a histopathological name that does not specifically refer to a particular disease, so pulmonary fibrosis does not belong to pneumoconiosis, but pneumoconiosis can cause pulmonary fibrosis. 1. Pneumoconiosis, usually due to long-term inhalation of inorganic mineral dust. As the dust is retained in the lungs for a long time, it leads to lattice-like fibrosis and diffuse nodular fibrosis in the lung tissue. Patients may experience symptoms such as coughing up sputum and shortness of breath. Generally speaking, pulmonary fibrosis does not belong to pneumoconiosis. 2. In patients suffering from pneumoconiosis, after the normal alveolar tissue in the body is damaged, the function of part of the lung tissue will be affected, and after the damaged alveolar tissue is repaired abnormally, the structure will be abnormal, which will lead to pulmonary fibrosis in patients. If you want to check whether you are suffering from pneumoconiosis or interstitial fibrosis, it is recommended that you go to the Department of Respiratory Medicine for a relevant examination. If you want to prevent pulmonary fibrosis or pneumoconiosis, you are advised to quit smoking, keep your environment ventilated and clean, and prevent infection.
