慢性支气管炎的症状是剧烈咳嗽和多痰,每个冬季至少发作3次。此病晚期往往导致慢性阻塞性肺病,这是一种进行性疾病,特征是通过的气流越来越小。严重的细菌感染可恶化此病,日益频繁的咳嗽和越来越多的痰液使病人的生活质量大幅下降。通常用抗生素治疗此病,但只能做周期性的短期治疗,效果是暂时的。 The symptoms of chronic bronchitis are severe cough and phlegm, occurring at least 3 times per winter. The late stage of the disease often leads to chronic obstructive pulmonary disease, which is a progressive disease characterized by the decreasing airflow. Severe bacterial infections can exacerbate the disease. The increasing frequency of coughing and the increasing amount of sputum make the patient’s quality of life significantly lower. The disease is usually treated with antibiotics, but only periodic short-term treatment can be performed. The effect is temporary.
