When the above clinical manifestations occur, airway hyperreactivity is considered. Bacterial infections, viral infections, atypical pathogenic bacterial infections, or allergies to food or drugs can all lead to airway hyperreactivity, so when the patient develops the above clinical manifestations, it is recommended that he or she actively seek medical attention, improve the detection of allergens, and improve the bronchial diastolic test and other investigations. If the patient is diagnosed with airway hyperreactivity, the first step is to avoid contact with allergic substances, such as animal fur or pollen. Secondly, oral leukotriene modifiers, such as montelukast sodium, inhaled glucocorticoids, which are commonly used in the clinic, such as Symbicort or Sulodexide, as well as relevant examinations to assess whether there is a pathogenic bacterial infection, and if there is a pathogenic bacterial infection, a targeted treatment should be taken.
