Chronic bronchitis cannot be cured because it is a chronic non-specific inflammation of the trachea, bronchial mucosa, and surrounding tissues. Clinically, cough and sputum are the main symptoms, accompanied by wheezing, and the onset of the disease occurs every year for three consecutive months or longer for two or more consecutive years. The coughing and coughing process for a long time has changed its structure and organization, so it cannot be cured for chronic bronchitis. Chronic bronchitis is divided into an acute exacerbation and a remission period. During the acute exacerbation, active control of infection, cough suppression, expectoration, and wheezing is performed. In the remission period, quit smoking, avoid inhaling harmful gases and other harmful particles, enhance physical exercise, and prevent upper respiratory tract infections. With active treatment, the progression of chronic bronchitis can be delayed, but it cannot be cured.
