Coughing and shortness of breath during inhalation may be caused by chronic respiratory diseases, respiratory infectious diseases or other reasons. 1. Chronic respiratory diseases: such as chronic bronchitis, bronchial asthma and other diseases may be accompanied by airway hyperreactivity, which may trigger airway spasm during inhalation or speech, causing coughing and shortness of breath. 2. Respiratory tract infectious diseases: such as pneumonia, tuberculosis, acute bronchitis, etc., the above diseases may also be accompanied by increased airway sensitivity, which may cause cough and chest tightness when inhaling. 3. Other diseases: such as lung cancer, airway foreign body, etc., may cause cough and chest tightness when inhaling. Therefore, coughing and chest tightness during inhalation need to go to the respiratory medicine department in time to investigate the cause of the disease.
