Airway hyperresponsive cough does not heal on its own. It is commonly seen in diseases such as bronchial asthma and eosinophilic pneumonia. Airway hyperresponsiveness has little to do with the age of the patient and has some relationship with heredity. An organism that develops airway hyperresponsiveness is susceptible to stimulation by various external allergens, causing spasm and contraction of bronchial smooth muscle, leading to narrowing and causing symptoms such as wheezing and dyspnea. It is one of the reasons for the occurrence of chronic bronchitis and bronchial asthma. Such patients can be treated with medications if necessary. Bronchodilator inhalation therapy can help relieve symptoms and prevent attacks. Some patients require long-term application of hormonal medications. If complicated by a bacterial infection, anti-infective treatment is required at the same time. Airway hyper-reactive cough is often triggered by exposure to cold air and allergens. Patients should avoid cold and flu, avoid exposure to pollen, and wear a mask when going out.
