Being able to cough up sputum does not necessarily mean that you are almost cured, but you need to consult a doctor to determine the course of the disease based on the test results. Whether you can cough up sputum or not is not a scientific basis for judging the course of the disease. Infectious lung diseases such as pneumonia or chronic lung diseases such as chronic bronchitis can cause excessive sputum production and coughing up sputum. In some cases, the phlegm may be sticky and difficult to cough up. Whether or not you are able to cough it up depends on your lung capacity, the consistency of your phlegm, and whether or not you have a habit of coughing up phlegm. Therefore, it is not possible to judge the course of the disease by whether or not sputum can be coughed up, and it is necessary to consult a doctor in a timely manner for lung X-rays, blood tests, C-reactive protein, pulmonary function tests, etc., to ascertain whether or not the infection is under control and whether or not the lung function has recovered, which is the scientific basis for judging the course of the disease. Therefore, it is recommended to consult a doctor in a timely manner, subject to the doctor’s opinion.
