半夜总是饿醒？当心是糖尿病的前兆，特别是这4个表现！

每天半夜被饿醒？可能是糖尿病的表现！

每天半夜被饿醒？别以为是胃口好、消化能力强的表现，如果你还同时伴有手抖、心慌等症状出现，当心是糖尿病发生的前兆，最好尽早进行血糖筛查！

半夜总饿醒要当心

糖尿病患者之所以总是半夜饿醒，是因为他们的胰腺功能发生了异常。

一般来说，普通人进餐15分钟后，胰岛素分泌会出现一个小高峰，而到了1小时则会达到最高峰；而糖尿病患者胰岛素分泌高峰会出现延迟的情况，不合时宜的胰岛素分泌会令患者血糖降低，从而产生饥饿感。

对于这种现象，建议糖尿病患者可以在饮食上做出调整，晚餐尽量避免吃深加工食物，适当进食纤维素含量以及蛋白质含量较高的食物。

不过，如果你睡觉没吃饭，又或者睡前一直处于节食状态，半夜饿醒仅仅是说明你饿了而已，此时肠胃会提醒你该补充能量，并不能说明什么。

糖尿病症状有哪些？

1、多尿

糖尿病人若血糖持续升高，葡萄糖经过肾小球过滤出来并不能够被肾小管完全吸收，就会形成渗透性利尿，导致尿量增加。

2、多饮

高血糖会使血浆渗透压增高，加上多尿的症状，就容易导致身体水分流失过多，进而导致脱水，令人产生口渴的情况。

3、体重下降

糖尿病患者体内胰岛素相对缺乏，或出现胰岛素抵抗现象，可致身体无法使用葡萄糖产生热量，这就让脂肪和蛋白质消耗过多，慢慢就会导致体重下降。

4、视力下降

很多糖尿病患者在早期都会出现视力下降、视物模糊现象，这主要是因为高血糖可致晶体渗透压发生改变，并引起屈光度变化。
