It is normal for a patient with pneumonia to cough and have sputum during the recovery period because during the treatment of a patient with pneumonia, the doctor will treat the cause of the pneumonia. After the cause is removed, the pathogens in the lungs need to be slowly expelled from the body, so the respiratory tract will discharge a large amount of sputum, and necrotic tissue. After the cause of pneumonia is cured, there will also be a recovery process. During this recovery period, patients with pneumonia need to pay attention to keeping warm to avoid getting cold, which can cause recurrent attacks of pneumonia. If there is more phlegm, you can also take cough and phlegm medicines under the guidance of your doctor, and you can go to the hospital for nebulization treatment if your symptoms are more severe. Also pay attention to a light diet, avoid spicy, stimulating and greasy food, drink more boiled water, and the symptoms of cough with phlegm will recover slowly.
