Coughing is a protective reflex action of the body. Pathological secretions, phlegm or foreign bodies enter the respiratory tract and trigger the body to cough them up through the cough reflex. The way to deal with phlegm in the throat and cough is as follows: 1. First of all, we need to clarify whether the cough with phlegm is caused by viral or bacterial infection, and we need to use targeted antiviral or antibacterial drugs; 2. If the cough has more phlegm, we generally do not advocate strong cough suppression, and we should try to let the phlegm out, which is good for infection control; 3. If the phlegm is sticky and not easy to cough out, you can use phlegm-suppressing drugs or nebulization under the guidance of a doctor to relax the airway and promote the timely discharge of phlegm; 5. Pat the patient’s back, drink more water and avoid eating greasy, spicy and stimulating foods.
