Chronic Obstructive Pulmonary Disease (COPD), short for Chronic Obstructive Pulmonary Disease, is usually not self-healing, and there is no such case. General treatment and medication are needed to alleviate it. 1. General treatment: Reducing exposure to risk factors in daily life, such as persuading patients to quit smoking is the most effective measure to slow down the damage of lung function. For those who suffer from occupational or environmental dust or irritating gases, they should get out of the polluted environment, strengthen occupational protection, and have regular medical checkups. 2. Medication: bronchodilators such as salbutamol and ipratropium bromide, glucocorticosteroids such as fluticasone, and expectorant medications such as ambroxol can be used under the guidance of a doctor. It is recommended that patients with chronic obstructive pulmonary disease consult a doctor for early and standardized treatment under the guidance of a doctor.
