Pneumoconiosis is a relatively insidious disease, the early symptoms are not obvious and non-specific, mainly manifested as respiratory symptoms, but sometimes also with extra-respiratory symptoms first diagnosed. 1. Respiratory symptoms: cough, sputum and dyspnea are common manifestations of early pneumoconiosis, of which dyspnea is the earliest manifestation of pneumoconiosis, the patient’s activity tolerance decreases, shortness of breath initially appears after activity, and dyspnea at rest develops with the development of the disease, the patient can be accompanied by chest pain and chest suffocation symptoms at this time. Coughing and coughing are not obvious in the early stage of pneumoconiosis, and when coughing occurs in patients, it is mostly an irritating dry cough, rarely accompanied by coughing sputum, but a few patients will have obvious coughing sputum in the early stage, and sometimes patients will cough sputum even when they cough very little, but the amount of coughing sputum is not much, and it is mostly gray thin sputum. 2. Extra-respiratory symptoms: common ones include chest pain, weakness, loss of appetite, nausea, vomiting, etc. Generally, chest pain is vague, but it can also be distended and pinprick-like pain, with different locations and often changing, mostly limited. Non-specific gastrointestinal symptoms such as loss of appetite, nausea and vomiting with no apparent cause can also occur. Early symptoms of pneumoconiosis are mild and do not easily attract the attention of patients, but groups with a history of occupational exposure should consciously undergo health screening as an important measure to detect the disease.
