低血压是指体循环动脉压力低于正常的状态。由于高血压在临床上常常引起心、脑、肾等重要脏器的损害而备受重视，世界卫生组织也对高血压的诊断标准有明确规定，但低血压的诊断尚无统一标准。根据病因可分为生理性和病理性低血压，根据起病形式可分为急性和慢性低血压。那么接下来找良医网为您介绍一下低血压的症状有哪些？

 

　\"头晕乏力当心低血压


1、头晕。有些人会出现没有原因就头晕，症状轻重不一，有时候甚至会两眼发黑，而症状比较严重的甚至会出现失神或者倒地不起。这种情况一般会出现在突 然站立的情况下，例如在上厕所的时候突然的站立会很可能会引发。另外，在平时静坐没有进行任何活动的时候也会出现这种情况。

 

2、出现疲乏、无力的感觉。有些人早上会出现乏力、没精神的状态，而经过休息或者午睡之后，又会得到缓解，而到了下午这些不适的感觉再度袭来，而这些也许是工作的疲惫而造成的，但如果从事比较轻松的工作也会出现以上的感觉，那么就要留意了。这很可能是低血压的症状表现。可以使用血压测量器，测测血压情况，看看是否在低血压范围之内。

 　

3、出现神经功能障碍。主要的表现有精神萎靡、记忆力变差、出现睡眠障碍等情况。另外，还会伴随有出汗多、皮肤苍白无血色，甚至会出现全身的突冷突热，有时候甚至觉得蚂蚁在身上爬。这些都可能是低血压导致的神经功能障碍。所以，大家一定要提高警惕，出现这些情况要及时的就医。

\"低血压多的症状有哪些


第一、低血压导致脑组织缺血性损害极为突出，会直接让人出现头晕头痛，口齿不清，呼吸困难，眼前发黑，昏厥，健忘迟钝，缺血性脑卒中，心绞痛，心肌梗死等。如果是老年人，还会有很大的几率出现痴呆症。

　　　

第二、患者会经常性的出现头痛、头晕的情况。在低血压的患者当中，头痛是最为明显的症状，这种情况的出现主要是由于患者在紧张的脑力活动或者体力活动以后会出现比较明显的症状，头痛的程度根据患者的病情而定，主要是在枕下位置出现隐痛的情况，也有是剧烈性的搏动性的疼痛，患者也经常性的出现头晕的情况，比较轻缓的患者经常出现两眼发黑，严重的患者会出现眩晕倒地的情况。会出现这样头痛头晕的情况主要是因为患者低血压导致致脑灌注不足有关。

 

　

第三、神经功能的障碍。主要表现是患者记忆力出现衰退，不能正常睡眠和出现失眠的情况，经常性的出现多汗和皮肤苍白无血色，忽冷忽热有时候全身会出现蚁爬感，手脚麻木等。

　　

第四、食欲减退，消化不良。低血压患者会出现食欲减退的情况，腹部出现疼痛感觉，经过检查会发现白细胞减少、血红细胞增多的情况。

　　

以上就是低血压患者的一些主要的表现，如果发现有这样的情况，应该及时到医院进行治疗。找良医网祝您早日康复！

\"u=2144341300,4096163462&fm=23&gp=0.jpg\"/

有时医生会遇到一些青年女性，她们的就诊原因是头晕，或者乏力。大多数这样的就诊者身体比较瘦弱。除了平时头晕乏力外，有的在早晨起床时感到精神疲惫、四肢乏力，头晕的症状在体位由卧姿改为坐姿或立姿时出现或者加重。还有的在午饭后嗜睡，精神无法集中。通过系统检查，没有发现任何异常，例如贫血和内分泌系统疾病。唯一的不正常就是血压低于正常值。严重者甚至为75/40mmHg。这就是典型的青年女性低血压病人。与其它低血压比较，青年女性低血压的发病和处理有其自己的特点。

什么是低血压？无论是由于生理或病理原因造成血压收缩压低于90mmHg，舒张压低于60mmHg就是低血压。

低血压又可以分为急性低血压和慢性低血压。例如大量失血形成的血压降低就是急性低血压。我们通常所说的低血压指慢性低血压。慢性低血压的分类有各种不同的方法。一般可分为三类：

体质性低血压:与遗传和体质瘦弱有关，多见于20－50岁的妇女和老年人，轻者可无如何症状，重者出现精神疲惫、头晕、头痛，甚至昏厥。在夏季气温较高时，有的体质较差的女性通常感到乏力头晕，有的就是因为低血压造成。因为此时血管扩张，使血压降低更明显。

体位性低血压：体位性低血压是患者从卧位到坐位或直立位时，或长时间站立出现血压突然下降超过20mmHg，并伴有明显症状，这些症状包括：头昏、头晕、视力模糊、乏力、恶心、认识功能障碍、心悸、颈背部疼痛，严重者甚至晕厥。体位性低血压与多种疾病有关，如多系统萎缩、糖尿病、帕金森氏病、多发性硬化病、更年期障碍、血液透析、手术后遗症、麻醉、降压药、利尿药、催眠药、抗精神抑郁药等，久病卧床及体质虚弱的老年人也多有发生。

继发性低血压：由某些疾病或药物引起的低血压，如脊髓空洞症，风湿性心脏病，降压药，抗抑郁药和慢性营养不良症，血液透析病人。究其原因因人而异多种多样。如风湿性心脏病的低血压与排血量减少有关；降压药物引起者与血压过渡降低有关；血液透析病人与血容量降低太多有关，等等。

这三种慢性低血压可以交错合并存在。例如青年女性低血压多属体质性低血压，如果体位变化加重症状则合并体位性，如果有风湿性心脏病，则也可能与继发性低血压有关。

鉴于以上分类没有强调低血压的发病基础是“有病”还是“非病”，所以更好的对指导疾病有价值的分类为把低血压分成生理性低血压和病理性低血压两类。

生理性低血压者体检检验及长期随访均无发现严重疾病。人体各系统器官无缺血和缺氧等异常，也不影响寿命。生理性低血压状态除见于年轻妇女，尤其是体型瘦长者，也可见于经常运动量较大者以致重体力劳动者。这些患者统称为青年女性低血压。这些人低血压的产生常与迷走神经紧张性较高有关。青年女性的生理性低血压预后良好，而且，由于心血管负荷较轻，循环器官的衰老可能还较血压正常者迟些，更可能获得高寿。处于生理性低血压状态的青年女性用不着为血压偏低而烦恼，也不需要为使血压恢复正常而四处求医，更不能因为在正规医院寻不到升压良方，就去盲目求助街头游医。生理性低血压患者轻者如无任何症状，无需药物治疗。如果有明显的头晕乏力可以采取积极参加体育锻炼的措施来改善体质，并且适当增加营养，多喝水，多吃汤，每日食盐略多于常人。经常服用中药黄芪、太子参、大枣和白扁豆也有相当的疗效。西洋参泡水饮用既可以双向调节血压有可以增加水分的摄入量。

病理性低血压指某种疾病导致。这些患者除动脉血压低于正常外，常伴有全身乏力、头晕、易疲倦、出汗、心悸等症状，当长时间站立或者由卧位（或坐位、蹲位）转为立位时，上述症状更为明显，甚至昏倒。慢性低血压可有遗传倾向，也可继发于某些神经性疾病、心血管疾病、慢性营养不良、内分泌功能紊乱、传染性疾病恢复期以及使用某些降压药时，常伴有相应的不适和检查异常。治疗病理性低血压重点在治疗原发病。如心功能不全导致者应该提高心脏收缩力，合理应用利尿剂。过渡利尿也是低血压原因之一。

青年女性的病理性低血压最常见的原因为内分泌疾病。只有控制了内分泌疾病，才可能使过低的血压恢复正常。所以，青年妇女有低血压并伴有闭经、性欲减退、毛发减少和色素沉着等症状和体征者，一定要到专科医生处就诊，早日发现病因而采取正确的治疗措施。

　低血压的症状：

\n

　　(1)疲乏、无力：尤其是早上，患者常感到精神萎靡不振、四肢酸软无力，经午睡或休息后可好转，但到下午或傍晚又感乏力，这种倦怠感与患者实际工作或活动所消耗的体力不相称，即这种乏力并非都是因过度所致。这种疲乏可能与神经系统功能紊乱导致过多的肌肉收缩不协调，而不恰当地消耗肌力所致。

\n

　　(2)头晕：在低血压病的患者中，头痛可以是惟一的主诉，其头痛往往在紧张的脑力或体力活动后较为明显，头痛性质和程度不一，多表现为颞顶区或枕下区隐痛，也可呈剧烈的搏动性疼痛或麻木性疼痛。头晕轻重不一，轻者两眼发黑、;重者可以失神，甚至倒地，常在突然改变，尤其是由蹲位突然起立时最易发生。此外，静止而又负担过重的工作条件下也易发生。头痛和头晕可能与血压低致脑灌注不足有关。

\n

　　(3)心前区隐痛或不适：低血压病患者心前区隐痛、不适，不仅可在体力劳动或紧张脑力劳动时发作，在安静时也可发作，甚至引起样发作，尤其多见于40岁以上患者，这种情况不仅见于低血压病并冠心病的患者，也可能由于血压过低本身导致冠脉供血不足，引起心肌缺氧、缺血而产生上述症状。

\n

　　(4)神经功能障碍：可表现为精神萎靡不振、记忆力减退、睡眠障碍和等。自主神经功能失调可表现为多汗、皮肤苍白或轻度发绀，浑身忽冷忽热，时有蚁爬感，手脚麻木等。

\n

　　(5)内分泌功能减退的现象：主要表现为肾上腺素和去甲肾上腺素一类物质不足，部分低血压患者降低和衰退。

\n

　　(6)其他：可表现为不振、腹部不适、消化不良，以及血增多、减少、抵抗力降低易引起感染等征象。还会引起咳嗽昏迷、排尿昏迷。

\n

　　原发性低血压病的诊断主要根据动脉血压测值达低血压标准，除外继发性低血压病和生理性低血压状态，结合上述临床表现可以作出诊断。

    1、根据病因可分为生理性和病理性低血压

    \n

    （1）生理性低血压者除动脉血压低于上述值外，无任何自觉症状。经长期随访，人体各系统器官无缺血和缺氧等异常，也不影响寿命。生理性低血压状态常见于年轻妇女，尤其是体型瘦长者，而经常从事较大运动量的运动和重体体力劳动者也不少见。其低血压的产生常与迷走神经紧张性较高有关。

    \n

    （2）病理性低血压（低血压病）除动脉血压低于正常外，常伴有全身乏力、头晕、易疲倦、出汗、心悸等症状，当长时间站立或者由卧位（或坐位、蹲位）转为立位时，上述症状更为明显，甚至昏倒。

    \n
    2. \n

    2、根据起病形式可分为急性和慢性低血压。

    \n

    （1）急性低血压是血压由正常水平或较高的水平突然明显下降，常见于体质弱者，主要表现为晕厥与休克两大类临床综合征。 

    \n

    （2）慢性低血压可有遗传倾向，也可继发于某些神经性疾病、心血管疾病、慢性营养不良、内分泌功能紊乱、传染性疾病恢复期以及使用某些降压药时，常伴有相应的不适和检查异常。

　　不少中老年人常发现这样一种现象：从沙发上站起来时头晕，起床一瞬间也会头晕，甚至上厕所起身时也会出现头昏、乏力、站立不稳、视力模糊等症状，此时，让人第一时间想到的是血压升高了。然而，美国北卡罗来纳大学的研究发现，不少人在坐下后再猛地站起来时，眼前常会发黑、头脑发晕，这其实是一种病症，医学上称之为“体位性低血压”。

　　体位性低血压又叫直立性低血压，即在平卧、下蹲后突然站起，收缩压突然下降超过20mmHg，并伴有明显的头晕、视物模糊、乏力、恶心、心悸等。通常情况下，人的体位改变，由平卧转为站立时，受重力影响，血液滞留在腹部及下肢，血压会有所下降，一般收缩压会下降5～10mmHg，但如果患者的自主神经功能紊乱引起血管舒缩调节功能不良，就会导致血压下降得更多，达到甚至超过20mmHg，出现明显的低血压症状。近年的临床研究和流行病学调查发现，体位性低血压与卒中、心肌梗死等密切相关，因而也越来越受到重视。

　　体位性低血压是老年人和儿童的常见病。据统计，65岁以上老年人体位性低血压者约占15%，而75岁以上的老年人可高达30%-50%。体位性低血压分突发性和继发性两种。突发性多因植物神经功能紊乱，引起直立性小动脉收缩功能失调所致;继发性多见于慢性营养不良或使用降压药、镇静药之后出现。

　　头晕，神志模糊是直立性低血压常见的临床表现。当出现低血压时，往往在站立时出现头晕、有时伴有轻微头痛、恶心、站立不稳，严重时发生昏厥，在夜间上厕所、清晨起床以及运动时容易出现体位性低血压，从卧位转为立位更加明显。老年人常有颈动脉硬化，在转动头部的时候也会发作，这主要是由于低血压引起脑血流减少所致。

　　检查直立性低血压需对比测量患者在仲卧、坐位以及站立时的血压。

　　如果发现直立性低血压，迅速检查明确是否有心动过速、意识水平的改变、脸色苍白、皮肤湿冷。如果这些体征都存在，则应考虑低血容量性休克。建立大静脉通路，以供补液或血液输注。每15分钟检测患者生命体征一次，并且记出入量。

　　病史和体格检查

　　如果患者没有生命危险，可以询问病史。如是否在站立时经常出现头晕、乏力或晕厥。还要询问与此伴随的症状，特别是疲劳、端坐呼吸、阳瘘、恶心、头痛、腹部或胸部不适及消化道出血。然后询问完整的用药史。

　　观察患者皮肤的肿胀情况。触摸周围脉搏搏动，听诊心脏和肺脏，最后检测肌张力和患者的步态是否乎稳。

   常见症状：头晕乏力、消化不良、心脑供血不足、疲乏、内分泌功能减退、慢性头痛、心前区隐痛、下肢血压偏低、腰膝酸软

　　根据低血压的起病形式将其分为急性和慢性两大类。

\n

　　1.急性低血压

\n

　　急性低血压是指患者血压由正常或较高的水平突然而明显下降，临床上常因脑、心、肾等重要脏器缺血出现头晕、眼黑、肢软、冷汗、心悸、少尿等症状，严重者表现为晕厥或休克。

\n

 

\n

　　2.慢性低血压

\n

　　慢性低血压是指血压持续低于正常范围的状态。

\n

　　(1)体质性低血压一般认为与遗传和体质瘦弱有关，多见于20～50岁的妇女和老年人，轻者可无任何症状，重者出现精神疲惫、头晕、头痛，甚至昏厥。夏季气温较高时更明显。

\n

 

\n

　　(2)体位性低血压部分患者的低血压发生与体位变化(尤其直立位)有关，称为体位性低血压。体位性低血压定义为：在改变体位为直立位的3分钟内，收缩压下降>20mmHg或舒张压下降>10mmHg，同时伴有低灌注的症状，这些症状包括：头昏、头晕、视力模糊、乏力、恶心、认识功能障碍、心悸、颈背部疼痛。老年单纯收缩期高血压伴有糖尿病、低血容量，应用利尿剂、扩血管药或精神类药物者容易发生体位性低血压。

\n

 

\n

 

\n

　　(3)继发性低血压某些疾病或药物可以引起低血压，如脊髓空洞症、高度的主动脉瓣狭窄、二尖瓣狭窄、慢性缩窄性心包炎、特发性或肥厚性心肌病、血液透析病人和慢性营养不良症等，以及服用降压药、抗抑郁药。这些疾病引起的低血压也可以出现头昏、头晕等低灌注的症状。
