Question
The patient inquires about the cause of their chronic recurring cough, especially the recent occurrence of coughing up blood, and how to stop the cough.
Answer
Doctors recommend a detailed examination for the chronic recurring cough to determine the underlying cause. For common colds, if symptoms are mild, medication may not be necessary. If the cough is caused by lung infection, treatment should target the source of infection, and nebulized inhalation medication can be used. For cough-variant asthma, inhaled corticosteroids or bronchodilators are typically used, and oral medications may be required in severe cases. If the cough is caused by gastroesophageal reflux disease, it is necessary to suppress stomach acid secretion.
