慢性咽炎的病因是什么?

来源:华人健康网 | 发布时间:2011-04-02 14:33:18 | www.chinesejk.com

  慢性咽炎的病因有多方面,综合起来分为以下三类:

  外界因素:生活地域气候寒冷、干燥,工作环境空气被粉尘、化学气体污染,烟酒、辛辣饮食长期刺激,都易得慢性咽炎。

  局部因素:急性咽炎反复发作,可转为慢性。邻近器官疾病,如慢性扁桃体炎、牙跟炎、龋齿、慢性鼻炎、慢性鼻窦炎等炎性分泌物流入咽部,或慢性鼻病造成鼻通气困难而用口呼吸;以及咽部长期受刺激而呈慢性炎症改变。

  全身因素:长期生活不规律;疲劳、精神紧张,使身体抵抗力下降;细菌和病毒容易反复感染。过敏体质的人对外界环境、气候的改变过度敏感,容易感冒,引起咽炎。
