Silicosis, also known as silicosis, is a very common and extremely serious form of pneumoconiosis. For example, Lao Zhang is a worker engaged in the coal industry, at the beginning may not feel any difference, but over time, the body began to cough with blood, chest tightness, shortness of breath symptoms, because Lao Zhang has nearly 30 years of smoking, at first Lao Zhang did not care about it, thinking that it is the reason for smoking, and began to reduce the number of cigarettes, but found that not only the symptoms have not been alleviated, but also aggravated, which is why Lao Zhang realized that it was silicosis. Something was wrong, and it was only after a checkup that he realized it was silicosis. Silicosis is one of the pneumoconiosis that progresses very quickly and is extremely harmful. Silicosis is caused by inhaling a large amount of silica dust, while pneumoconiosis is a disease that is mainly characterized by fibrotic lesions of the lungs. Silicosis is asymptomatic or has no obvious symptoms in the early stages, and as the disease progresses gradually, the condition will become more unstable. The diagnosis of silicosis and pneumoconiosis is also different. Pneumoconiosis can be clarified by examination of lung function and image analysis, while silicosis can be diagnosed by chest ct examination. Patients should pay attention to the working environment and living environment, keep away from harmful dust, eat more food to clear phlegm and moisturize the lungs, refrain from smoking, and have regular checkups to control and treat the disease in time.
