你健康吗？医生告诉你指甲揭示健康的秘密

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、Vertical lines, however, are generally not such a big deal. Some people are more genetically prone to them than others, but they're commonly associated with aging. Occasionally they may appear in malnourished people.

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、When people are iron-deficient, their nails can turn spoon-like, according to Derick. Instead of curving down and covering the finger normally, they'll start to rise up on the sides and front, going from the normal convex shape to a more concave shape, like the part of a spoon that holds liquid.

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、Kidney and liver problems can create "half-and-half nails," where one part of the nail is white and the other part dark or pink, according to Derick. Kidney and liver problems frequently cause discoloration that shows up in nails and skin.
