Adults with frequent coughing need to register with a respiratory medicine department. Frequent coughing in adults is commonly associated with respiratory diseases, such as acute upper respiratory tract infections, which may sometimes leave a post-infection cough that causes coughing symptoms to extend for 1-2 months, and related diseases such as tuberculosis, which can also lead to prolonged coughing, or even cough variant asthma, allergic cough, airway foreign bodies, chronic bronchitis, bronchial dilatation, interstitial lung fibrosis, nodular disease, lung cancer, and other related conditions. In addition, it should be noted that frequent coughing in adults can also be due to other systemic pathologies, not always due to respiratory diseases, but sometimes to chronic cardiac insufficiency and gastroesophageal reflux cough, etc. If these diseases are present, further diagnosis should be made in the appropriate department and actively managed.
