The asthma we usually talk about mainly refers to bronchial asthma, which is a respiratory system disease. The most suitable department to consult for bronchial asthma is the department of respiratory medicine, and in places where no specific department of respiratory medicine exists, the department of general internal medicine can be consulted. However, the precondition for consulting these departments is that the patient's condition must be stable. If a patient with bronchial asthma experiences a severe acute attack and has serious breathing difficulties, they must seek treatment in the emergency department. Additionally, some types of asthma refer to cardiac asthma, which, as the name suggests, is a cardiovascular disease and thus requires consultation in the department of cardiology.
