The expectoration period is an irregularity, and the general public will refer to the period of time when the cough and sputum are still high after the control of respiratory inflammation as the expectoration period, and the coughing symptoms may be aggravated.
Coughing up sputum is a common manifestation of inflammatory diseases of the respiratory tract, even if the inflammation is under control, it is still necessary to cough to discharge the secretions, white blood cells and necrotic products of pathogens from the diseased area, and it may even be necessary to cough several times and with greater force to be able to discharge the deeper sputum from the lungs, which is a kind of coughing reflex, and so the symptoms of coughing may worsen during the period of sputum expectoration.
As the sputum gradually decreases, the coughing symptoms will gradually decrease. If sputum is not expelled and the coughing symptom is getting worse, you should go to the hospital in time, complete the relevant examinations under the guidance of the doctor and actively treat the coughing symptom.
