Symptoms of chronic bronchitis
The symptoms of chronic bronchitis primarily include coughing, expectorating phlegm, or accompanied by wheezing. Coughing generally occurs mainly in the morning, with bouts of coughing or expectoration during sleep. The sputum is white, viscous, or serous foamy, and is more prevalent in the morning. Getting up or changing body position can stimulate expectoration. In patients with prominent wheezing symptoms, it is referred to as asthmatic bronchitis, and some may also develop bronchial asthma. However, the presence of emphysema can manifest as shortness of breath after labor or activity. If the condition persists for three months each year, for two consecutive years or more, it can be clinically diagnosed as chronic bronchitis.
How to treat chronic bronchitis?
Chronic bronchitis is divided into acute exacerbation phase and remission phase. The treatment during acute exacerbation mainly focuses on controlling infections, and administrating antitussive, expectorant, and asthma-relieving medications. To control infections, antibiotics are empirically selected based on the common pathogens in the area. If the pathogen can be cultured, an antibiotic sensitive to the organism can be chosen based on the test. Oral administration is generally sufficient. In severe cases, medication can be administered intravenously. Patients with asthma are given bronchodilators. During the remission phase, treatment involves quitting smoking, avoiding inhalation of harmful gases and other harmful particles, strengthening physical health, preventing colds, and for patients with repeated respiratory infections, vaccines or immunomodulators may be administered to enhance immunity.
