Hello Dr. Zhang, my child is seven years old and has had a cough for a month. Every time

Patient's question:

No

Doctor's answer:

Hello, coughing is a protective respiratory reflex action of the human body. The production of coughing occurs when foreign matter, irritating gases, or secretions in the respiratory tract stimulate the receptors in the respiratory tract mucosa. The impulse is transmitted through the sensory nerve fibers to the cough center in the medulla, causing coughing. The key is to identify the cause of the cough to treat it correctly.
