There are many factors that cause patients to cough incessantly with sputum, which may be due to the following causes: 1. Patients may have inflammatory infections in the trachea and bronchi. The mucous membrane of trachea and bronchus will secrete a lot of inflammatory secretions under the stimulation of inflammation, so it will lead to cough and sputum symptoms. 2. Patients may suffer from chronic lung diseases and have acute infections, such as acute attacks of chronic bronchitis and bronchial dilatation. 3. Patients may also have cough and sputum symptoms caused by tuberculosis due to the infection of tubercle bacilli in the lungs. . When patients have frequent coughing and coughing symptoms, they should go to the hospital in time for relevant examinations, such as chest X-ray and lung CT, to identify the cause and then proceed with treatment.
