(二)临床表现 大多数地方性甲状腺肿病人起病缓慢, 早期仅见甲状腺轻度肿大,多为弥漫性,一 般无明显症状。当甲状腺肿大到一定程度时, 压迫气管和食道可引起呼吸困难和吞咽困难。 肿大的甲状腺压迫喉返神经,可出现声音嘶 哑、痉挛性பைடு நூலகம்嗽等刺激性症状。

(三)诊断标准 ▲
我国现行地甲病的诊断标准如下: 1.生活于碘缺乏区(水碘低于10μg/L,尿 碘 低 于 100 μg / L ) ; 高 碘 地 区 ( 水 碘 高 于 300μg/L,尿碘高于800 μg/L);或存在致 甲状腺肿大物质之地区。
地区分布 :除冰岛外,IDD在世界各国都有不同 程度的流行。主要分布于欧洲阿尔卑斯山脉两侧 国家,北美洲五大湖盆地,南美洲安第斯山脉, 非洲刚果河流域,亚洲喜马拉雅山地区,大洋洲 巴布亚新几内亚一带。最主要的国家有孟加拉、 巴西、中国、印度、印度尼西亚、巴基斯坦、尼 日利亚和俄罗斯,这8个国家占全世界缺碘人口的 54%。一般来说,碘缺乏的表现为山区重于丘陵、 丘陵重于平原、内陆重于沿海。
14
碘缺乏病的主要病因及发病机制
1.营养因素 IDD的发生与不合理的膳食有密切关 系,如低蛋白、低热量的膳食可影响肠道对碘的吸 收,以及甲状腺对碘的吸收和转化。有人发现,某 些病区居民膳食中维生素A、C、B12不足可促使甲 状腺肿发生,这可能是因为维生素是氧化还原酶的 重要组成成分,维生素不足影响了甲状腺激素合成 过程中一系列氧化还原过程。因此,从某种意义讲 IDD是以碘缺乏为主的多种营养素缺乏症。
17
碘缺乏的病因
4. 环境污染物 重金属:铅、汞、铬、锰等 有机氯农药:六六六、DDT PCB 硝酸盐

临床表现
地方性甲状腺肿(endemic goiter),简称 地甲病,其主要症状是甲状腺肿大。
