Bronchitis refers to a chronic non-specific inflammation of the tracheobronchial mucosa and its surrounding tissues. Clinically, it is characterized by long-term coughing and expectoration, or accompanied by wheezing and repeated episodes.

Actively control the infection. In the acute phase, be sure to follow the doctor's advice on medication and choose effective antibacterial drugs for treatment. If bronchiectasis is not actively treated, it may cause hemoptysis, coughing, and repeated bronchial and pulmonary infections.

If bronchiectasis is not actively treated, it may lead to coughing and repeated bronchial and pulmonary inflammatory infections, which can result in lung abscess, lung gangrene, empyema, and pyopneumothorax. When extensive fibrosis occurs in the lung tissue and the pulmonary capillary bed is severely damaged, it can lead to an increase in pulmonary artery circulation resistance.
