Whether a cough with yellow sputum and yellow nose can be cured by itself depends on different causes. Cough and sputum are common clinical manifestations of the respiratory system. If the cough is caused by a viral infection, it can slowly recover after a period of time through life conditioning, keeping warm, drinking more water, taking rest and eating a light diet. If it is caused by bacterial infection, it is recommended to use medication to get better results. Cough with yellow sputum and yellow nasal discharge is commonly associated with acute bronchitis, pneumonia, lung abscess, bronchiectasis, acute exacerbation of chronic obstructive pulmonary disease and many other diseases. It is recommended that the patient go to the respiratory department of the hospital for a chest radiograph to rule out acute lung infection. The patient can check the blood routine to see if the white blood cells are abnormally elevated, take sputum for sputum culture plus drug sensitivity test, and select a sensitive antibiotic for anti-inflammatory treatment according to the drug sensitivity results of the sputum culture. Patients should usually work and rest regularly, eat normally, improve immunity and cardiopulmonary function.
