长期血管堵塞不仅会导致手脚麻木、胸闷气短等不适症状，还会损伤心血管健康，因此要及时调理，但是要怎么知道自己的血管是否堵了呢？血管堵了自己有感觉吗？不少人对此不了解，下面就为大家盘点血液病的三大预警信号。
一、血管堵了自己有感觉吗
血管堵塞初期一般是没有感觉的，因此很难察觉，但随着血管堵塞的时间延长，就会逐渐出现胸闷气短、手脚麻木等不适症状，可当这些症状出现时，也说明血管堵塞的问题已经比较严重，可以说是错过了最佳的调理时机，所以为了保险起见，青年和中年人建议一年进行一次体检，老年人半年进行一次体检，实时监测身体的情况，确保身体健康，若有血管堵塞问题，也能及时进行生活方式干预或者直接治疗。
二、血液病的三大预警信号
1、手脚麻木
血管堵塞以后，血液的流通速度会变慢，肌肉的血氧量也会随之降低，因此手脚等肌肉量大的部位就会出现血氧量不足的情况，从而出现肌肉功能下降、感知能力减弱等问题，最终导致手脚麻木等不适症状，影响患者的工作和生活。
2、胸闷气短
血管瘀堵问题的出现，会严重影响气血的流通，不仅会减慢气血的运行，还会减少单次气血循环的供血量，因此身体各个器官的供血就会不足，最终使得身体各个器官的功能被减弱，比如心脏的泵血功能减弱等，如此一来，不仅会导致胸闷气短，还会让供血一次比一次少，形成恶性循环。
3、头晕耳鸣
脑部对血氧的要求是比较高的，如果大脑的供血不足，大脑的功能不仅难以维持，还会出现多种不适症状，比如头晕、神经性耳鸣、失眠等，严重危害人体健康，而血管被堵塞，血液流通出现疾病问题以后，由于大脑位于人体最高的位置，供血会迅速减少，从而导致供血不足，引起身体不适。
以上就是本文的全部内容，一般来说，血管堵塞初期是没有症状的，只有血管堵塞问题比较严重，已经或者将要转化为高血压、高血脂等血液疾病了，才会出现手脚麻木、胸闷气短、头晕耳鸣等不适症状，因此大家最好每年做一次体检，确保早发现早治疗。
