Hipotensiune<\/h2>\n

 <\/p>\n

Tensiunea arterial\u0103 joas\u0103, cunoscut\u0103 ca \u0219i hipotensiune, apare când tensiunea arterial\u0103 din artere este anormal de sc\u0103zut\u0103. Tensiunea arterial\u0103 este înregistrat\u0103 ca dou\u0103 m\u0103sur\u0103ri în milimetrii de mercur (mmHg):<\/p>\n

tensiune sistolic\u0103 – tensiunea când inima începe s\u0103 bat\u0103 \u0219i împinge sângele în artere<\/p>\n

tensiune diastolic\u0103 – tensiunea când inima se odihne\u0219te între b\u0103t\u0103i<\/p>\n

Oamenii cu tensiune arterial\u0103 de 90\/60 sunt considera\u021bi ca având tensiune arterial\u0103 sc\u0103zut\u0103.<\/p>\n

 <\/p>\n

Simptome<\/h2>\n

Simptomele tensiunii arteriale pot fi:<\/p>\n

ame\u021beal\u0103<\/p>\n

grea\u021b\u0103<\/p>\n

vedere înce\u021bo\u0219at\u0103<\/p>\n

senza\u021bie general\u0103 de sl\u0103biciune<\/p>\n

le\u0219in<\/p>\n

respira\u021bie rapid\u0103<\/p>\n

sete<\/p>\n

 <\/p>\n

Când tensiunea arterial\u0103 scade brusc, poate fi semnul anumitor probleme.<\/p>\n

 <\/p>\n

Cauze<\/h2>\n

Exist\u0103 mai multe cauze pentru tensiunea arterial\u0103 sc\u0103zut\u0103. Acestea sunt:<\/p>\n

deshidratarea (când corpul pierde mai mult\u0103 ap\u0103 decât acumuleaz\u0103, când nu be\u021bi suficiente lichide, dac\u0103 transpira\u021bi mult pe durata activit\u0103\u021bilor fizice, febr\u0103, vom\u0103, diaree sever\u0103<\/p>\n

sarcin\u0103, care dispare dup\u0103 na\u0219tere<\/p>\n

sc\u0103dere brusc\u0103 dup\u0103 mas\u0103 la b\u0103trâni<\/p>\n

Anumite condi\u021bii medicale care pot provoca hipotensiune, ca:<\/p>\n

probleme de inim\u0103: atac de cord, boala valvei inimii, bradicardie (un procent sc\u0103zut al inimii) \u0219i insuficien\u021b\u0103 cardiac\u0103, care împiedic\u0103 inima din a pompa suficient sânge c\u0103tre corp<\/p>\n

infec\u021bii severe, cum ar fi septicemie<\/p>\n

anemia<\/p>\n

probleme endocrine, cum ar fi tulbur\u0103rile tiroidiene, boala Addison, nivel sc\u0103zut de zah\u0103r în sânge \u0219i diabet<\/p>\n

tulbur\u0103ri ale sistemul nervos central, cum ar fi Parkinson<\/p>\n

embolie pulmonar\u0103<\/p>\n

Medicamentele pot provoca hipotensiune. Aceste medicamente sunt:<\/p>\n

diuretice<\/p>\n

blocante ale canalelor de calciu<\/p>\n

Angiotensin – inhibitorii enzimei (ACE)<\/p>\n

Angiotensin II – blocant receptor<\/p>\n

Nitra\u021bi<\/p>\n

Blocant beta<\/p>\n

 <\/p>\n

Medicamente pentru problemele ca anxietatea, depresia, disfunc\u021bia erectil\u0103 \u0219i tulbur\u0103rile sistemului nervos central pot cre\u0219te riscul de hipotensiune.<\/p>\n

Alte substan\u021be, ca alcoolul, \u0219i unele medicamente \u0219i medicamentele f\u0103r\u0103 prescrip\u021bie pot fi cauza hipotensiunii.<\/p>\n

 <\/p>\n

O cauz\u0103 sever\u0103 a hipotensiunii este legat\u0103 de \u0219oc. La \u0219oc, tensiunea arterial\u0103 scade foarte mult \u0219i nu se întoarce la normal de una singur\u0103. Exist\u0103 diferite tipuri \u0219i cauze pentru \u0219oc: septic (când bacteria intr\u0103 în sânge), hipovolemic (când exist\u0103 sângerare sever\u0103, pierderea lichidelor din corp, umflarea pancreasului, diaree sever\u0103, boal\u0103 sever\u0103 de rinichi), cardiogen (abilitatea redus\u0103 a inimii de a pompa sânge), vasodilatatoare (relaxarea extrem\u0103 a arterelor din cauza r\u0103nirii severe la cap, reac\u021bia la anumite medicamente, insuficien\u021ba hepatic\u0103, otr\u0103virea), \u0219ocul anafilactic (alergie).<\/p>\n

 <\/p>\n

Factori de risc<\/h2>\n

Tensiunea arterial\u0103 sc\u0103zut\u0103 poate afecta pe oricine. Unii dintre factorii de risc sunt: luarea unor medicamente, o alt\u0103 problem\u0103 medical\u0103, cum ar fi diabetul.<\/p>\n

 <\/p>\n

Complica\u021bii<\/h2>\n

Complica\u021biile hipotensiunii sunt: ame\u021beal\u0103, sl\u0103biciune, le\u0219in sau ob\u021binerea insuficient\u0103 de oxigen pentru func\u021bionarea normal\u0103 a organelor, care poate cauza probleme inimii \u0219i creierului.<\/p>\n","protected":false},"author":9,"featured_media":0,"template":"","yoast_head":"\nHipotensiune - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.humanitas.net\/ro\/diseases\/hipotensiune\/\" \/>\n<meta property=\"og:locale\" content=\"ro_RO\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Hipotensiune - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Hipotensiune   Tensiunea arterial\u0103 joas\u0103, cunoscut\u0103 ca \u0219i hipotensiune, apare când tensiunea arterial\u0103 din artere este anormal de sc\u0103zut\u0103.
