现今我国大部分地区已经进入冬季,今年的冬天冷的比往年要早一些。进入冬季,全家老少围坐在一起,吃上一顿热乎乎的火锅,那真是再好不过了。可是小李却高兴不起来了,到底是怎么回事呢?

在一次和朋友在火锅店聚会后,小李吃的非常开心,聚会后回到家中感觉肚子不是很舒服,本以为因为火锅底料是辣的,肠稍微有些不适,也没在意。可是到了后半夜疼痛的症状加剧了,赶紧到附近医院救治,医生诊断为——急性肾衰竭。

那大家会问,那么多人吃火锅为什么都没事,小李怎么会吃成这样呢?原因是小李的肾脏本身就患有疾病,火锅中动物内脏、豆制品、反复煮的火锅底料、啤酒都含有较高的嘌呤,过多摄入将导致尿酸增多,引起高尿酸症、尿酸性肾结石、肾功能减退等肾脏病变。火锅又有高脂、高盐的特点,过多食用对肾脏的负担就会加大。

那么如何预防肾病的发生呢?

专家建议最少每年要进行一次体检,对肾脏的整体功能进行检测。血液检测中肌酐、尿酸、尿素等试验可以帮助您了解肾功能的情况。下面我们来分别了解一下它们的作用:

肌酐是肌肉在人体内代谢的产物,主要由肾小球滤过排出体外。临床上检测血肌酐是常用的了解肾功能的主要方法之一。当血肌酐值高时说明患者的肾功能出现了问题,肾脏代谢废物的能力下降,体内的一些有害毒素不能正常的排出体外,同时患者还会有高血压、高度浮肿等身体其他症状。血肌酐的浓度变化主要由肾小球的滤过能力(肾小球滤过率)来决定。滤过能力下降,则肌酐浓度升高。血肌酐值高出正常值多数意味肾脏受损,血肌酐能较准确的反映肾实质受损的情况,并非敏感指标。

尿素是血浆中除蛋白质以外的一种含氮化合物,它从肾小球滤过而排出体外。在肾功能不全失代偿时,尿素将升高。所以临床将其作为判断肾小球滤过功能的指标。尿素氮是人体蛋白质代谢的主要终末产物,尿素从肾小球滤过后在各段小管均可重吸收,但肾小管内尿流速越快重吸收越少,也即达到了最大清除率。和血肌酐一样,在肾功能损害早期,血尿素氮可在正常范围。较易受饮食、肾血流量的影响,如有蛋白质分解因素-感染肠道出血、甲亢等可使尿素氮升高。

血尿酸是体内的老旧细胞,还有食物,尤其是富含嘌呤的食物(如动物内脏、海鲜等)在体内新陈代谢过程中,其核酸氧化分解产物就有嘌呤(这种内源性的嘌呤占总嘌呤的80%)。但如果体内产生过多来不及排泄或者尿酸排泄机制退化,则体内尿酸潴留过多,当血液尿酸浓度大于7毫克/分升,是人体体液变酸,影响人体细胞的正常功能,长期置之不理将会引发痛风。另外过于疲劳或是休息不足亦可导致代谢相对迟缓导致痛风发病。

从上文中我们可以了解,“火锅”肾病患者慎吃为妙!饮食火锅宜清淡,多吃蔬菜是好的选择,一旦出现肾病症状一定要选择正规的肾病医院进行治疗。
