Defini\u021bie<\/h2>\n

Sincopa vasovagal\u0103 este una dintre cele mai frecvente cauze ale le\u0219inului. Le\u0219inul, numit \u0219i sincop\u0103, este cunoscut ca o scurt\u0103 pierdere a cuno\u0219tin\u021bei. Se produce atunci când exist\u0103 o oprire temporar\u0103 a fluxului sanguin c\u0103tre creier, determinând o sc\u0103dere brusc\u0103 a ritmului cardiac \u0219i a tensiunii arteriale. Aceast\u0103 întrerupere a fluxului sanguin, care duce la le\u0219in, poate fi cauzat\u0103 de mai mul\u021bi factori, cum ar fi vederea sângelui, crizele convulsive, sc\u0103derea glicemiei, un \u0219oc emo\u021bional extrem sau statul în picioare timp îndelungat.<\/p>\n

Sincopa vasovagal\u0103 în general nu necesit\u0103 tratament, deoarece este o problem\u0103 temporar\u0103 inofensiv\u0103 a sistemului nervos autonom. Un medic poate recomanda câteva examene medicale, pentru a exclude cele mai grave cauze ale le\u0219inului, cum ar fi tulbur\u0103rile cardiace, \u0219i s\u0103 ofere un diagnostic adecvat pentru tratamentul ulterior dac\u0103 este necesar.<\/p>\n

 <\/p>\n

Simptome<\/h2>\n

Înainte de a le\u0219ina, o persoan\u0103 poate sim\u021bi urm\u0103toarele:<\/p>\n

Sl\u0103biciune<\/p>\n

Nelini\u0219te<\/p>\n

Grea\u0163\u0103<\/p>\n

Transpira\u021bii reci<\/p>\n

C\u0103scat<\/p>\n

Paloare a pielii<\/p>\n

Vedere înce\u021bo\u0219at\u0103 sau în tunel.<\/p>\n

Recuperarea dintr-un episod vasovagal tinde s\u0103 apar\u0103 în mai pu\u021bin de un minut de la le\u0219in. Ridicarea prea rapid\u0103 de jos poate atrage un nou le\u0219in.<\/p>\n

 <\/p>\n

Cauze<\/h2>\n

Sincopa vasovagal\u0103 apare atunci când un anumit declan\u0219ator determin\u0103 o func\u021bionare temporar\u0103 defectuoas\u0103 a unei p\u0103r\u021bi a sistemului nervos, cea care regleaz\u0103 ritmul cardiac \u0219i nivelul tensiunii arteriale. Sc\u0103derea tensiunii arteriale \u0219i ritmul cardiac încetinit restric\u021bioneaz\u0103 alimentarea cu sânge a creierului, f\u0103când ca persoana în cauz\u0103 s\u0103 le\u0219ine. Un episod simplu, cunoscut sub numele de atac vasovagal sau sincop\u0103 neuro-mediat\u0103, este cel mai frecvent tip dele\u0219in.<\/p>\n

Declan\u0219atoarele comune pentru sincopa vasovagal\u0103 includ urm\u0103toarele:<\/p>\n

Statul în picioare pentru o perioad\u0103 lung\u0103 de timp<\/p>\n

Ridicarea în picioare prea repede<\/p>\n

Expunerea la temperaturi ridicate<\/p>\n

La vederea sângelui<\/p>\n

La donarea de sânge<\/p>\n

Teama de r\u0103nire corporal\u0103<\/p>\n

Un incident stresant<\/p>\n

Încordare în timpul unei mi\u0219c\u0103ri intestinale<\/p>\n

Deshidratare<\/p>\n

Lipsa de somn<\/p>\n

Foame<\/p>\n

Crampe menstruale severe<\/p>\n

Diabetul necontrolat<\/p>\n

Anumite medicamente<\/p>\n

Anumite boli care afecteaz\u0103 sistemul nervos<\/p>\n

 <\/p>\n

Tratament<\/h2>\n

În majoritatea cazurilor de sincop\u0103 vasovagal\u0103, nu este necesar niciun tratament. În cazurile mai grave, când sunt le\u0219inuri frecvente, scopul principal este acela de a g\u0103si cauza principal\u0103. Un medic poate recomanda una din urm\u0103toarele op\u021biuni de tratament:<\/p>\n

Midodrin\u0103: Un tip de medicamente utilizate pentru tratarea nivelurilor sc\u0103zute ale tensiunii arteriale<\/p>\n

Exerci\u021bii specifice pentru picioare, pentru a sc\u0103dea acumularea de sânge în ele<\/p>\n

Purtarea ciorapilor de compresie, pentru a îmbun\u0103t\u0103\u021bi circula\u021bia sângelui<\/p>\n

Înv\u0103\u021barea tehnicii de tensionare a mu\u0219chilor din picioare, bra\u021be \u0219i trunchi prin exerci\u021bii specifice<\/p>\n

Ad\u0103ugarea de mai mult\u0103 sare la mesele zilnice<\/p>\n

Cre\u0219terea consumului de potasiu<\/p>\n

Consumarea de multe lichide pentru hidratatare<\/p>\n

Evitarea statului prelungit în picioare<\/p>\n

Antrenament de biofeedback: tehnic\u0103 utilizat\u0103 pentru a controla b\u0103t\u0103ile rapide ale inimii, prin trimiterea de semnale de avertizare prin senzori electrici, în timpul activit\u0103\u021bii neobi\u0219nuite a inimii<\/p>\n

Interven\u021bie chirurgical\u0103, dac\u0103 este necesar (inserarea unui stimulator electric, pentru a ajuta la reglarea ritmului cardiac)<\/p>\n

 <\/p>\n

Profilaxia<\/h2>\n

Preveniree cert\u0103 a episoadelor de sincop\u0103 vasovagal\u0103 este pu\u021bin probabil\u0103, chiar \u0219i în cazul acord\u0103rii de tratament. M\u0103surile specifice care pot ajuta o persoan\u0103 în timpul unui episod includ întinderea pe jos \u0219i ridicarea picioarelor, pentru a permite gravita\u021biei s\u0103 direc\u021bioneze fluxul sanguin spre creier.<\/p>\n","protected":false},"author":9,"featured_media":0,"template":"","yoast_head":"\nSincopa vasovagal\u0103 - 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\/sincopa-vasovagala\/\" \/>\n<meta property=\"og:locale\" content=\"ro_RO\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Sincopa vasovagal\u0103 - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Defini\u021bie Sincopa vasovagal\u0103 este una dintre cele mai frecvente cauze ale le\u0219inului.
