Whether bronchitis causes a cough all the time depends on the type of bronchitis and the condition of the patient. In the early stages of acute bronchitis, patients can have a cough that is more intense and frequent. In acute bronchitis patients, the cough can be gradually reduced or disappeared through comprehensive symptomatic treatment such as anti-infection, cough suppression, removal of phlegm and nebulized inhalation, etc. The course of treatment for acute bronchitis is about one week. For patients with chronic bronchitis, they may have chronic cough and sputum symptoms. Some patients with chronic bronchitis may not have obvious cough symptoms when they are in the stable stage, but when chronic bronchitis is acutely aggravated, their cough symptoms may be significantly aggravated. Therefore, for patients with bronchitis, their condition can be judged according to the degree and characteristics of their cough, and their corresponding treatment can be guided.
