指甲出现横纹,是肾病或心肌梗塞发病的先兆;出现纵纹,缺少维生素A,是肝病的先兆.还有人说是因为缺钙
竖纹:指甲表面不够光滑,出现一条条的直纹,一般会出现在操劳过度、用脑过度后;在睡眠不足的时候,这些竖纹会很清楚地显现出来。如果竖纹一直存在,则可能是体内器官的慢性病变。如果不加以调养,随着病情的发展指甲会变得高低不平,甚至会裂开。
凹沟形:指甲上有较深的凹沟,表示有此形指甲的人体内寄生虫数量多,或有肠道麻痹。大拇指甲有凹沟,常有精神不振;食指甲有凹沟,皮肤易发疹;中指甲有凹沟,表示患有肌无力症;无名指甲有凹沟,易患目疾;小指甲有凹沟,易患肝胆系疾病及咽喉炎、神经痛等。
跷而曲起形:指甲中间部分薄弱,甲上有横纹,有此形指甲的人常患有钩虫病,说明机体缺钙、贫血或营养不良
中凹横线形:有此形指甲的人可能有寄生虫病。
纵线形:指甲上有纵线纹,且容易折断,有此形指甲的人多为心功能不好或肠蠕动减弱。大拇指指甲上有较多纵线纹,可能是因偏食引起。
异常指甲与主病
正常人的指甲为手指第三指骨的一半,幅度不宽不窄,富有弹性,不易折断,有一定的硬度,边缘与肉平行,呈淡红色,富有光泽,无斑点,无凹凸。
如果指甲小于第三指骨一半,多属体质衰弱、消瘦,消化系统功能紊乱,但抗病力强。指甲较软的人,精力差,易疲劳,喜睡眠,抗病能力差,常萎磨不振。指甲硬脆易断的人,常有贫血,食欲不振。指甲上有白斑或云母样,表示缺钙硅等微量元素,并有寄生虫,这种人易神经过敏,易烦躁,有习惯性便秘。
指甲根部的淡色弧形圈称甲半月弧,俗称健康圈。正常的健康圈面积约占指甲的?-1/5,无阴影。健康圈的宽窄、大小因人、因种族而异。通常男性健康圈约3毫米,女性略小,食指、中指、无名指宽窄依次递减,小指多无。老人较窄,营养不良者常消失。健康圈的变化最能提示机体营养状况,是人体营养状况的提示灯。
不知目前身体有何不适?可能是患了灰指甲,也可能是缺乏维生素、微量元素等所致。建议到医院检查清楚明确诊治。
指甲上有白点或白斑,如经常有肚子痛症状,可能是有蛔虫。或消化功能不好。还可以体内缺乏某种微量元素(这种较常见)。因此建议先到正规医院检查后再对症治疗。有部分指甲凹凸不平**面粗糙无光泽有凹沟、纵条纹、白斑、健康圈比例不正常多为体质较差之兆。加强营养,还要补充钙质.
