What are the early symptoms of bronchitis?

1. Cough: Long-term, repeated, and gradually worsening cough is a prominent manifestation of this disease. The mild ones only occur in the winter and spring seasons, especially before and after getting up in the morning, and there is less cough during the day. Cough reduces or disappears during summer and autumn. In severe cases, the cough in the four seasons, the winter and spring intensified, coughing day and night, especially in the morning and evening.

2. Expectoration: Generally, it is white foamy foamy, more in the morning, often because it is sticky and not easy to slip out. Symptoms rapidly increase after infection or cold, increased sputum, increased viscosity, or yellow purulent sputum or wheezing. Occasionally because of a cough and blood in the sputum.


3. Asthma: When combined with respiratory infection, due to congestion and edema of the bronchial mucosa, sputum occlusion and bronchial stenosis, symptoms of asthma (wheezing) can occur. There is a wheezing sound in the patient's throat while breathing, and a wheezing sound in the lungs during auscultation. This type of wheezing is a clinical manifestation of asthmatic bronchitis; however, its seizures are not like typical bronchial asthma.

4. Infection: Repeated respiratory infections are likely to occur during cold seasons or sudden changes in temperature. At this time, the patient's asthma increased, the amount of sputum increased significantly and was purulent, accompanied by general malaise, chills, fever and so on. Wet sounds appear in the lungs, and blood leukocyte counts are increased. Repeated respiratory infections are particularly prone to worsening the condition of elderly patients and must be given full attention.
