At present, there is no cure for chronic bronchitis, and most treatments are mainly aimed at alleviating its symptoms. The treatment is mainly divided into two parts, one is the treatment during the acute exacerbation phase, which means that if a patient with chronic bronchitis experiences acute worsening of symptoms such as coughing and expectoration, or if accompanied by wheezing, fever, etc., then the main treatment methods might include anti-infection measures, expectorants to relieve cough, or treatments to alleviate wheezing. Most patients with chronic bronchitis are likely in the remission phase most of the time, and the primary treatment during this phase is initially to address factors that might trigger chronic bronchitis, such as insisting that patients who smoke quit smoking, and for those who have been exposed to dust or smoke, it is crucial to resolve triggering factors and avoid contact with harmful gases or inhalation of harmful particles. The next step is to enhance physical fitness and prevent colds. Chronic bronchitis patients can engage in appropriate physical exercise based on their condition, and those who suffer from long-term recurrent infections might consider pursuing immunotherapy.
