Patient: Frequent cough, sometimes with phlegm, what medicine can eradicate it ?
Zhang Xianxin, Department of Respiratory Medicine, Shandong Chest Hospital: Usually you have to pay attention to avoid risk factors: quit smoking, reduce occupational dust and chemical inhalation, reduce indoor and outdoor air pollution, avoid getting cold, prevent colds and reduce recurrent respiratory infections. Also flu shots can reduce the severity of the attack and perhaps reduce the number of attacks as well as the symptoms during the attack. However, if there is airflow obstruction and it cannot be completely reversed, the diagnosis of COPD can be made, and then it is impossible to cure the disease. Some non-pharmacological treatments are also available, such as performing respiratory muscle function exercises, doing abdominal breathing, deep and slow exhalation, and doing home oxygen therapy. Pulmonary function tests are recommended. Zhang Xianxin, Department of Respiratory Medicine, Shandong Provincial Chest Hospital
