Chronic coughing of white sputum is mainly considered to be caused by chronic bronchitis, which is a chronic non-specific inflammation of the tracheobronchial tubes and surrounding tissues. The onset of the disease persists for more than three months per year, often for two or more consecutive years. It can be caused by frequent smoking, recurrent attacks, having acute bronchitis that is not treated in time, or having low body resistance or frequent exposure to irritants, and has a higher incidence in middle-aged and elderly people, with recurrent attacks and gradual worsening of the disease. In addition to cough and phlegm, it is also easy to have wheezing and the body’s resistance ability gradually decreases. Generally, sputum test, blood test, chest X-ray and respiratory function test are done. In the acute stage, antibacterial and anti-inflammatory drugs and anti-cough and asthma drugs are also needed. In the chronic stage, attention should be paid to strengthening physical fitness and appropriate exercise to improve the body’s resistance.
