There is no authoritative statistics on the average life expectancy of patients with chronic obstructive pulmonary disease (COPD). Those with good control can reach their natural age, but poor control can greatly shorten their life expectancy, which is closely related to the quality of the individual’s health and the timeliness of treatment. If the disease can be early in the timely medical treatment, according to the doctor’s instructions for treatment, usually better control, less frequent infections, did not occur in respiratory failure and other complications, it is generally able to have a normal natural life expectancy, the current average life expectancy of the country is about 75 ~ 80 years. However, if the disease is not treated at an early stage, and the disease progresses rapidly, the life expectancy can be significantly shortened. Complications such as respiratory failure and pulmonary heart disease can be life-threatening if not treated in time. Patients with chronic obstructive pulmonary disease are advised to consult a doctor in a timely manner, quit smoking, exercise appropriately, enhance physical fitness, and avoid colds.
