德里克指出，患有肺气肿等肺部疾病的人常会形成所谓的棒状指甲。棒状指甲就是指尖变圆，指甲盖弧度变大。 2、<span word="Small">Small</span> <span word="little">little</span> <span word="pits">pits</span> <span word="or">or</span> <span

指甲上的小凹痕是患上关节炎，银屑病性关节炎或湿疹的先兆。纽约大学的皮肤病专家桃瑞丝戴博士指出，关节炎会损害关节并可能引发像牛皮癣、湿疹这样的皮肤病。 3、<span word="People">People</span> <span word="who">who</span> <span word="aren">aren</span> <span word="t">t</span> <span

word="to">to</span> <span word="break">break</span>, <span word="according">according</span> <span word="to">to</span> <span word="Day">Day</span>. 戴博士认为，饮食不健康，缺乏维生素或饮食不规律的人的指甲可能比一般人的指甲薄，更容易断裂。 4、<span word="Horizontal">Horizontal</span> <span word="lines">lines</span>, <span word="also">also</span> <span word="known">known</span> <span word="as">as</span> <span word="Beau">Beau</span> <span

word="in">in</span> <span word="an">an</span> <span word="Everest">Everest</span> <span word="expedition">expedition</span>. 指甲上的横纹，也叫博氏线，预示着严重的身体压力。戴博士指出，它们横贯指甲，呈锯齿状的横纹状，常见于正在接受化疗的人的指甲上。一些疾病、伤病初愈，或严重营养不良的人亦会出现此状。有趣的是，这也可能与海拔高度的变化有关。潜水1000英尺以上或去珠峰探险过的人的指甲也会如此。 5、<span word="Vertical">Vertical</span> <span word="lines">lines</span>, <span word="however">however</span>, <span word="are">are</span> <span word="generally">generally</span> <span word="not">not</span> <span word="such">such</span> <span

word="malnourished">malnourished</span> <span word="people">people</span>. 然而出现纵线却不是大问题。一些人更容易因遗传而获得这种症状，但是这种症状多与衰老相关。营养不良的人偶尔也会有这种症状出现。 6、<span word="When">When</span> <span word="people">people</span> <span word="are">are</span> <span word="iron">iron</span>-<span word="deficient">deficient</span>, <span word="their">their</span> <span word="nails">nails</span> <span

<span word="that">that</span> <span word="holds">holds</span> <span word="liquid">liquid</span>. 德里克指出，缺铁的人，指甲会变得像勺子。与正常指甲向下包住指尖的形状不同，缺铁的人指甲前端和两侧会向上翘起，形成凹面，就像能盛水的勺子前端。 7、<span

德里克指出，肾病和肝病会引起对半两色甲，指甲的颜色一半白，一半粉色或黯淡无光。肾病和肝病常会引起指甲和皮肤变色。 8、<span word="A">A</span> <span word="nail">nail</span> <span word="that">that</span> <span word="lifts">lifts</span> <span word="up">up</span>

<span word="while">while</span> <span word="examining">examining</span> <span word="patients">patients</span>. 德里克还说，指甲从甲床上脱出说明人体患有肾病或甲状腺疾病。皮肤科医生在为病人检查时发现，许多甲状腺疾病和自身免疫病都伴随此类症状。 <span
