According to the latest epidemiological survey data, the number of chronic obstructive pulmonary disease in my country is nearly 100 million, and the incidence of chronic obstructive pulmonary disease in adults over 40 years old is as high as 13.7%, which is equivalent to that of residents over 40 years old, one in eight people is chronic obstructive Lung patients.

COPD has become the most common chronic disease besides hypertension and diabetes, and smoking is the biggest risk factor for COPD.

COPD has the characteristics of high prevalence, high disability, and high fatality rate, which seriously affects the prognosis and quality of life of middle-aged and elderly patients, and causes a heavy medical burden.

　　"At present, it is recognized that smoking is the biggest risk factor for COPD, and the greater the amount of smoking, the longer the smoking period, and the younger the age at the beginning of smoking, the higher the risk of COPD." Deputy Department of Respiratory and Critical Care Medicine, Henan Provincial People's Hospital Chief physician Zhang Qianqian said that more than 20% of smokers will develop chronic obstructive pulmonary disease, and long-term "second-hand smoke" will increase the risk of chronic obstructive pulmonary disease by 48%.

Therefore, smoking cessation is the main method to prevent COPD.

　　Experts suggest that early detection and early treatment of COPD are essential. People aged 40 and over have the main symptoms of COPD, smoking history, occupational dust exposure history, chemical exposure history, biofuel smoke exposure history, and COPD Family history is a high-risk group of COPD, and it is recommended to have a lung function test every year.
