在高血压读者作者交流群里，有患者经常问：长期低血压对身体有什么影响？下面小编带领大家了解一下。

在生活中很多人认为只有高血压才会对身体造成危害，认为血压高了会引起很多并发症，觉得血压低点没事，但其实这是一种错误的认为，因为血压偏高和偏低都会对健康造成严重的影响。那么长期低血压对身体有什么影响呢？

1、长期低血压由于血管腔内的压力长期低于正常水平，所以低血压患者的血液循环速度会有所减慢，这样就会导致肢体末端的毛细血管出现供血供氧不足的情况，而且器官也可能会受到影响，这样就会严重影响器官的功能。

2、身体的血液不断可以给器官提供氧气和营养，而且还可以带走器官和组织产生的代谢废物和二氧化碳，如果患者有低血压，那么会引起二氧化碳和代谢废物排放减少，这样就会对心脏功能造成非常大的影响，而且还会对大脑造成危害。

3、长期低血压还会严重影响患者的日常生活，导致患者出现心悸、心慌、头晕、头痛等一系列不适症状，对于病情比较严重的患者来说，还有可能引起晕厥，这样就会大大提高意外发生的几率。      

4、长期低血压还有可能引起脑缺血、心绞痛等并发症的发生，甚至有可能危害中枢神经系统，导致患者出现抑郁症等精神疾病，再往严重一些就会出现脑卒中的症状，如果心脏缺血的话，也会出现心肌梗死的情况，这对患者的生命安全造成了严重的威胁。

5、除此之外，低血压严重者，常常会伴有听力下降，视力也随之模糊起来，据研究发现，低血压也会使患老年痴呆症的概率大大增加。也会出现口齿不清、呼吸困难，严重者需要长期卧床，影响正常生活。

通过上面的介绍大家要了解，低血压和高血压一样都会对我们的身体找造成危害的。长期低血压对身体的危害非常大，我们要定期测量自己的血压，发现病情后患者应该及时进行对症治疗，以维持正常的血压水平。

在日常的生活之中，患者应该调整自己的饮食，血压低的人可以多吃一些高钠、高胆固醇饮食。氯化钠(即食盐)每日需摄足12-15克(但食盐摄入量亦不可太高)。含胆固醇多的脑、肝、蛋、奶油、鱼卵、猪骨等食品，适量常吃，有利于提高血胆固醇浓度，增加动脉紧张度，使血压上升。均衡的补充各种营养，减少病情的发生。

通过本文您将了解血压偏低有什么好处，为什么有这些好处：

 \"血压偏低有什么好处\"

我们的血管就像一条河道，我们的血液就像河道里面的水。正常情况下，河道里面的水川流不息的向前流，流向大脑，流向心脏，流向全身各处，源源不断的向各个脏器输送富含氧和其他营养物质的血液，保证他们正常的工作。如果河道发生淤堵、变得不通畅，水流就会减少，心、脑、肾等组织器官就会出现缺血、缺氧，就会发生功能异常，甚至坏死（比如心肌梗死、脑梗死）。所以血管里面的血液舒畅的流动是保证生命健康的重要保障。

 

如果河道上游的水压太高，河里的水流就会过于汹涌，有可能冲坏河岸，导致河水外流。同样，血压过高的时候，血管里的血液就会因为压力过高而撕裂血管，血液就会流到血管外面，脑出血就是这样发生的。不过一般情况下，我们的血管结构是很结实的，不容易被冲破。所以除非血压特别高，或者血管本身有畸形（即血管壁存在薄弱之处），一般不容易发生脑出血。

 

实际上，高血压最常见的的危害是引起心梗、脑梗，这是为什么呢？我们还拿河流打比方。河流都会有很多弯曲或者分叉之处，这些部位的河岸最容易被河水冲坏，形成缺损。动脉血管同样如此。高血压患者的血流压力很高，天长日久之后很容易把血管拐弯儿或者分叉部位的血管内皮冲坏，形成小破口。出现小破口后，血液中的胆固醇就会乘机进入血管壁里面，逐渐积累增多，形成动脉粥样斑块（动脉粥样斑块本质上就是血管壁内累积了很多胆固醇）。如果不进行有效处理，斑块就会越来越大，导致血管狭窄，这个部位通过的血流就会减少，于是出现心脏或脑等器官供血不足。如果斑块突然破裂，会迅速堵塞血管，使血流完全中断，心脏或脑完全失去血液供应，就发生坏死。心梗、脑梗就是这样发生的。

 

所以说，在保证全身血液供应的情况下，让血压低一些，动脉血管壁就不容易被血流损坏，就不容易发生粥样斑块，也就难以发生心梗、脑梗。当然，血压太低也不行。居民大楼的水压过低，楼上自来水就会供不上去。血压太低也会导致心脏或大脑缺血，同样有害。那么，血压维持在多少最好呢？一般来讲，收缩压（即平时所说的高压）在110-130 mmHg之间最佳，舒张压（即平时所说的低压）在70-80 mmHg最佳。太高或者太低都不好。当然，最理想的血压水平因人而异，所以上述标准也不是千篇一律的。

 

对于没有高血压的健康人，应该努力将自己血压维持在120/80 mmHg以下；对于高血压病人，应该尽量控制在130/80 mmHg以下。在保证心脑供血的前提下，血压低一些，血管就会更安全一些，发生心梗脑梗的风险就会更低一些。

\"低血压是什么原因导致的\"

 

生理性低血压


生理性低血压通常指的就是哪些身体健康的人，除了血压偏低以外，身体没有其它任何的症状，身体器官也无缺血或是缺氧的情况，更不会对身体有身体影响。

 

这一类低血压的患者，低血压的原因多是因为身体体质太弱，常常表现在一些年轻，体质瘦弱的女性身上。该类患者多为原发性低血压，当月经周期到的时候，也会转变为继发性低血压。特别是在月经量过多的时候，甚至可能引起昏厥。

 

相信不少年轻的女性都会有冬天身体冰凉的情况，不管穿多少衣服，身体也不会暖和，就这就因为血压偏低加上贫血所引起的。因此，对于生理性低血压的原因导致的身体状况，最好是能够通过饮食、运动的方法来治疗。

 

病理性低血压

 

这种情况的患者，除了有低血压的情况以外，还会出现身体上的症状或是疾病。病理性低血压可以分为两类，即原发性低血压和继发性低血压。原发性低血压症指的是没有原因的低血压，也就是生理低血压。继发性低血压指的是人体的器官疾病所引起的血压降低情况。

 

原发性低血压的原因这里就不多说了，具体跟大家谈谈继发性低血压的原因。继发性低血压多是在短时间内迅速发生的。像是大出血、严重的创伤、感染、过敏、急性心肌梗死都是可能会导致血压急剧下降的。

\"低血压的发病原因到底是有什么\"


第一、生理性的低血压，就是在部分健康的人群中，经过检查测试是发现达到低血压的标准，但是患者并没有其他明显的症状，经过长期的随访，除了血压偏低以后，没有任何的不适，不影响正常的工作和生活。

　　

第二、病理性的低血压病。

 

1. 原发性低血压病，就是没有原因莫名的出现该病症。

 

2.继发性低血压病。是指人体中器官或者系统性的疾病导致出现血压偏低的情况，这种情况是比较严重的，可以迅速的出现虚脱或者休克的症状。

　　血压低的原因有哪些?血压低容易导致人气血两虚，但是，很多人都知道自己血压低，不知道为什么自己会血压低。我们就来看看这方面的原因的介绍吧。

 

\"血压低的原因有哪些\"


　　1、血压低可能是因为心脏疾病引起的

 

　　罹患心不全、心肌梗塞、大动脉瓣狭窄症时，如果患者患有心脏方面的疾病的话，这是比较麻烦的，比较容易遭到这方面疾病的困扰，都会影响心脏搏出血液的功能，使心脏输送血量减少，以致循环障碍而引起低血压。

 

　　2、血压低可能是因为末稍血管扩张引起的

 

　　因细菌或毒素侵犯末稍血管，使血管失去收缩功能，这样的话，血管的部分功能就容易受到阻碍了，容易受到威胁了，容易没有什么影响和帮助了，很多人就会面临血压低带来的各种生活中的不方便和问题，导致血管扩张、血压下降，产生循环障碍性低血压。

 

　　3、血压低可能是因为暂时性大失血引起的

 

　　因手术、外伤的大量出血，因为手术的原因，导致人体出现了很多的问题，很多的麻烦，使体内循环的血液量骤减，而引起暂时性低血压。

 

　　4、血压低可能是因为甲状腺机能低下引起的

 

　　甲状腺机能减弱时，会出现气力减退、这样的话，人体就会有各种各样的麻烦和各种各样的不适应，感觉比较累，身心疲惫、就是莫名其妙地就会感觉到特别地劳累，不知道怎么回事，畏寒、皮肤乾燥等现象，而引起内分泌障碍性低血压。

 

　　5、血压低可能是因为艾狄逊氏症引起的

 

　　罹患此症会影响副肾皮质荷尔蒙的分泌，人体的激素的分泌就会受到影响，出现问题，使患者出现皮肤变黑、恶心、呕吐及低血压等症状。

找良医网向您详细介绍低血压的病理病因，低血压主要是由什么原因引起的。低血压是怎么回事？

 

\"低血压是怎么回事\"


低血压根据其产生的原因不同，大致上可分为：

 

1.生理性低血压状态

生理性低血压状态是指部分健康人群中，其血压测值已达到低血压标准，但无任何自觉症状，经长期随访，除血压偏低外，人体各系统器官无缺血和缺氧等异常，也不影响寿命。

 

2.病理性的低血压病

除血压降低外，常伴有不同程度的症状以及某些疾病。低血压病可分为：指无明显原因的低血压状态，如生理性低血压(体质性低血压)和病理性低血压(低血压病)。

 

低血压虽然不算是一种疾病，但可能是其他疾病所致，而且它会使人头晕眼花、精神疲惫、 注意力不集中或昏倒、休克，而导致其他伤害产生。医师提醒民众，确实了解低血压的原因，并 做好保健或治疗，才能避免影响日常生活或产生并发症。

 

原发性低血压病的发病机制迄今未明，多数学者认为可能属于中枢神经细胞张力障碍有关的疾病，由于中枢神经系统的兴奋与抑制过程的平衡失调，血管舒缩中枢的抑制过程加强，血管收缩与舒张动态平衡发生障碍，血管舒张占优势，最终导致动脉血压降低。

 

部分低血压患者完全没有症状，有些人则会出现耳鸣、头痛、头晕、眼花、肩膀酸痛、四肢 冰冷、疲倦、思考力减退、注意力不集中，或胸部有压迫感、灼热感，或腹鸣、便秘、下痢、肠 积气、腹部鼓胀，或男性出现阳萎、女性出现无月经等现象。

 

出现上述症状时，应速至医院或健康检查机构，接受心脏、血管、肠胃等各方面的检查，以便查出真正的致病因，即早治疗。
