Chronic obstructive pulmonary disease is irreversible and progressive, and generally cannot be cured. Chronic obstructive pulmonary disease (COPD) is a disease characterized by incomplete and reversible airflow limitation caused by a variety of reasons. The airflow limitation persists and often manifests itself in chronic cough, sputum, dyspnea, etc., which is often recurrent and aggravating, and is often associated with smoking, inhalation of dust and hazardous gases, and air pollution, among other factors. Most patients with chronic obstructive pulmonary disease (COPD) need long-term medication to control their condition so as not to aggravate it. Some patients stop taking medication when their condition improves, which may lead to recurrent episodes or persistent exacerbation of the condition. As the condition progresses, complications such as pulmonary hypertension and respiratory failure may occur. The use of medication varies among individuals, and it is recommended to standardize treatment under the guidance of a doctor to stop the progression of the disease and improve the quality of life.
