Cough is mostly a symptom of respiratory diseases, commonly caused by acute or chronic bronchitis, pneumonia, lung cancer, tuberculosis, etc. The duration of cough is related to the etiology of the disease, and the main treatment methods are divided into etiological and symptomatic treatment. In terms of etiological treatment, if the cough is caused by acute bronchitis, pneumonia or chronic bronchitis, it is necessary to clarify what kind of pathogen causes the infection. In terms of symptomatic treatment, it is recommended to keep warm, avoid getting cold, and protect yourself from climate change. You can use dietary therapy such as iced sugar snow pears and steamed oranges with salt, or use some phlegm-suppressing drugs such as ambroxol, bromhexine and dextromethorphan under the guidance of a doctor. Quick treatment of cough is mostly done with central cough suppressants, which are generally not recommended to be used alone, as they may cause sputum not to be easily expelled and lead to the occurrence of airway obstruction. Therefore, it is important to treat the cause of the cough and it is not recommended to use central cough suppressants alone to treat the cough quickly. If the cough persists, it is necessary to be alert to the occurrence of chronic respiratory diseases and it is recommended to consult a specialist to further clarify the diagnosis.
