Bronchitis belongs to respiratory medicine. Bronchitis is a respiratory disease due to infectious or non-infectious factors, so it belongs to respiratory medicine. If a patient has any of the following symptoms, he or she can go to a respiratory medicine department, such as cough, sputum, dyspnea, fever, chest pain, or hemoptysis. Although these symptoms are not always due to respiratory diseases, a respiratory physician can improve relevant tests to triage the disease based on the symptoms. If the symptoms are caused by respiratory system diseases, symptomatic medication can be applied, but if they are caused by other system diseases, such as cardiovascular system, urinary system, etc., it will be recommended to go to the relevant department for further treatment. If you don’t know what department to go to when you go to the hospital, you can go to the information desk first and then register.
