How is emphysema caused?

There are many causes of emphysema, including smoking, air pollution, occupational dust exposure, repeated respiratory infections and proteinase-antiprotease imbalance. If emphysema patients do not actively intervene, they may further lead to complications such as COPD, cor pulmonale and respiratory failure. Therefore, once emphysema is diagnosed, it is necessary to intervene as soon as possible, quit smoking, and stay away from the causes of the disease. At the same time, improve the body's ability to resist disease and reduce the occurrence of respiratory tract infection, which can prevent the further development of emphysema. At the same time, it is necessary to regularly review lung imaging and lung function tests to achieve early intervention treatment.
