Emphysema is usually not completely treatable. Emphysema is a condition in which the compliance of the lungs is reduced and the elasticity of the alveoli is decreased, causing an increase in the amount of residual air in the lungs and a decrease in lung function. The next step in the development of emphysema is pulmonary heart disease, which usually develops over a period of time from chronic bronchitis. This disease cannot be completely cured, and there is no specific medicine, but only medication and physical fitness to slow down the development. First of all, it is necessary to enhance physical exercise, prevent colds and reduce the frequency of the onset of bronchitis. Quit smoking, appropriate activities that can enhance immunity, such as jogging, swimming, etc. Pay attention to warmth and avoid getting cold. You can regularly get influenza vaccine and pneumonia vaccine when you are in better health, and actively treat the symptoms of coughing and coughing caused by colds.
