Cough is one of the most prevalent symptoms of bronchopulmonary diseases. If cough persists ( > 6 weeks), further workup is mandatory. The most common causes of persistent cough in nonsmokers presenting with a normal CXR are postnasal drip due to chronic rhinitis-sinusitis, cough equivalent asthma or gastroesophageal reflux. The response to empirical therapy may confirm one of these etiologies. Other causes of chronic cough need further extensive workup involving radiologic, functional and endoscopic procedures.
咳嗽是支气管肺部疾病最常见的症状之一。如果咳嗽持续存在（>6周），则必须进一步检查。胸部X线正常的非吸烟者持续性咳嗽最常见的原因是慢性鼻炎-鼻窦炎引起的鼻后滴漏、咳嗽变异性哮喘或胃食管反流。经验性治疗的反应可能证实这些病因之一。慢性咳嗽的其他原因需要进一步进行广泛的检查，包括放射学、功能和内镜检查。
