Chronic allergic cough has a certain possibility of developing into asthma, but patients can control their allergic cough with aggressive treatment to prevent asthma from developing. When the airways come into contact with allergens such as pollen and dust, airway hyperresponsiveness and long-term irritation of the airways cause chronic airway inflammation, which is similar to the pathological basis of asthma attacks, so there is a certain possibility that long-term allergic cough can develop into asthma. However, if the patient pays attention to avoiding contact with allergens such as pollen and dust, avoiding foods that may cause allergies, exercising appropriately to improve one’s immunity, and actively controlling chronic airway inflammation with medication in their normal life, asthma may be prevented from occurring. If the patient has allergic cough, it is recommended to consult the hospital and standardize the medication to avoid delay.
