Tracheitis is mainly due to a decrease in a person's resistance, and some pathogenic microorganisms from the external environment infect the trachea, forming some infectious inflammation on the tracheal mucosa, producing a large amount of secretions, and forming sputum. We call this disease tracheitis. Due to the large amount of secretions and sputum in the airway, the person will actively cough to expel these sputum from the body. Therefore, the typical symptom of tracheitis is coughing. Some patients may have severe inflammation and exhibit symptoms of fever. If the tracheitis continues to spread downwards and affects the bronchi, the patient may experience some respiratory difficulties, which we call bronchitis. In this case, treatment with some antibiotics and expectorants is necessary.
