Ingabe i-vasoconstriction ijwayelekile?

"I-Vaso" empeleni isho umthambo wegazi. IVasoconstriction inciphisa noma inciphise imithambo yegazi. Kwenzeka lapho izicubu ezibushelelezi ezindongeni zemithambo yegazi ziqina. Lokhu kwenza ukuthi umthambo wegazi uvuleke ube mncane. IVasoconstriction nayo ingabizwa nge-vasospasm.

IVasoconstriction inqubo ejwayelekile. Kuyasiza ukugcina umzimba wakho usesilinganisweni esinempilo.

IVasoconstriction kungenzeka ku:

  • ukuzinzisa umfutho wegazi noma ukukhuphula umfutho wegazi
  • ukunciphisa ukulahleka kokushisa komzimba emazingeni okushisa abandayo
  • lawula ukuthi igazi lisatshalaliswa kanjani emzimbeni wakho wonke
  • thumela izakhamzimba eziningi kanye ne-oxygen ezithweni ezizidingayo
  • vikela umzimba wakho ekulahlekelweni yigazi noketshezi

Ngakolunye uhlangothi, i-vasoconstriction engajwayelekile ingadala izimo ezithile zempilo. Lokhu kufaka phakathi umfutho wegazi ophezulu nobuhlungu bekhanda. Kwezinye izimo, ukunciphisa kakhulu isitsha segazi kungaba nomphumela oseceleni wezidakamizwa nokudla, njenge-caffeine nosawoti.

Funda ukuze ufunde ngezimbangela ze-vasoconstriction nokuthi uthinta kanjani umzimba wakho.


IVasoconstriction nomfutho wegazi

IVasoconstriction inciphisa ivolumu noma isikhala ngaphakathi kwemithambo yegazi ethintekile. Lapho ivolumu yemithambo yegazi yehliswa, ukugeleza kwegazi nakho kuyehla. Ngesikhathi esifanayo, ukumelana noma amandla okugeleza kwegazi kuphakanyisiwe. Lokhu kubangela umfutho wegazi ophakeme. Umfutho wegazi ophezulu ongalashiwe (umfutho wegazi ophakeme) ungaholela ezimeni zezempilo ngokuhamba kwesikhathi, njengokulahleka kombono, isifo sohlangothi noma inhliziyo elimele.

Okuphambene ne-vasoconstriction yi-vasodilation.Yilapho imithambo yegazi ikhululeka khona futhi ikhula, kwandise ukugeleza kwegazi futhi kwehle umfutho wegazi.

Cabanga nge-vasoconstriction njengokuphuza ngotshani obuncane. Kuthatha amandla amaningi okudonsa ukuthatha isiphuzo. Uma kuqhathaniswa, i-vasodilation ifana nokukhipha isiphuzo kalula futhi ngokushesha ngotshani obubanzi.

I-vasoconstriction engajwayelekile ingadala noma ibhebhethekise umfutho wegazi ophakeme. Umfutho wegazi ophakeme onganyuki ungakhuphula ubungozi besifo senhliziyo nokushaywa unhlangothi. Ezinye izimo zezempilo kanye nezidakamizwa kungadala i-vasoconstriction eningi kakhulu noma kwenze ukuthi kwenzeke ezindaweni ezingafanele, njengezingxenye zobuchopho.


Ukudla okubangela i-vasoconstriction

Ukudla okune-sodium eningi kungabeka ingcindezi emithanjeni yegazi lakho, kubenze banciphise. Uma ukhathazekile ngomfutho wegazi, gwema noma nciphisa ukudla okulandelayo:

  • ukudla okuhlanganisiwe nokusheshayo
  • dlulisa inyama
  • isobho elisemathinini

Utshwala lungakhuphula nomfutho wegazi, kuphawula iMayo Clinic.

Yidla lokhu kudla okungu-13 ukwehlisa umfutho wegazi.

IVasoconstriction ku-migraines kanye nekhanda

IVasoconstriction ingasiza ekunciphiseni futhi kubangele i-migraines nekhanda.

Lapho i-vasoconstriction isiza ikhanda

Imithambo yegazi eyandisiwe ekhanda ingasusa ubuhlungu be-migraine noma bekhanda. Imithi yokwelapha lolu hlobo lobuhlungu ivame ukusebenza ngokubanga i-vasoconstriction. Lokhu kusiza imithambo yegazi ukuminyanisa futhi imise ukugeleza kwegazi okweqile.

Eminye imishanguzo yekhanda neye-migraine iqukethe i-caffeine ngenxa yalesi sizathu.

Lapho i-vasoconstriction ingadala ikhanda

Ngakolunye uhlangothi, i-caffeine eningi kakhulu ingadala i-vasoconstriction eyeqile ebuchosheni. Lokhu kungadala i-migraine noma ikhanda. I-American Migraine Association ichaza ukuthi lokhu kungenzeka ngoba umzimba uncika ku-caffeine. Izimpawu zokuhoxa emithini yekhofi neyekhanda zibandakanya ubuhlungu bekhanda, isicanucanu nokukhathala.


IVasoconstriction ngokwethuka

I-Shock yigama elijwayelekile lokuphendula komzimba ezimeni eziningi zezimo eziphuthumayo ezahlukahlukene. Lezi zimo zonke zidala umfutho wegazi ophansi. Impendulo yokuqala yomzimba ukuvikela ubuchopho, inhliziyo, namaphaphu. Lokhu ikwenza ngokunciphisa imithambo yegazi ezandleni, ezinyaweni, nasemilenzeni.

Le vasoconstriction ephuthumayo inyusa umfutho wegazi okwesikhashana. Kuyasiza ukugcina igazi ligeleza ezithweni zakho ezidingeka kakhulu - izitho ezidingekayo impilo yonke.

Ukushaqeka kungenzeka ngenxa yalokhu:

  • ukusabela okweqile (ukushaqeka kwe-anaphylactic)
  • ukutheleleka ngokweqile (ibhaktheriya, igciwane, noma ukhunta)
  • isifo senhliziyo
  • Isifo senhliziyo
  • ushukela wegazi ophansi
  • ihluli
  • ukulahleka kwegazi okunzima (ngaphakathi noma ngaphandle)
  • ukulahlekelwa okukhulu kwamanzi (ukungabi namanzi, ukuhlanza, isifo sohudo)
  • ukusha okukhulu
  • ukulimala komgogodla
  • i-hypothyroidism enamandla

Imithi ebangela i-vasoconstriction

Imishanguzo yeVasoconstrictor noma yokucindezela isiza ukukhulula umfutho wegazi ophansi nezinye izimpawu. Le mithi ingasetshenziselwa ukukhuphula umfutho wegazi lapho othile eshaqekile, wopha ngokweqile, noma ephendula kanzima emzimbeni.

Eminye imishanguzo kadokotela ibangela i-vasoconstriction ukusiza ukunciphisa ukuvuvukala, ukuvuvukala, noma ukopha ngokweqile. Isibonelo, ukuphuma kwegazi kungamiswa ngomuthi we-vasoconstrictor.

Imithi yeVasoconstriction ifaka:

  • i-alpha-adrenoceptor agonists
  • ama-analogs we-vasopressin
  • epinephrine
  • norepinephrine
  • i-phenylephrine (i-PE ehlaselwe)
  • i-dopamine
  • dobutamine
  • imithi ye-migraine nekhanda (i-serotonin 5 ‐ hydroxytryptamine agonists noma i-triptans)

Izimo zezempilo ezijwayelekile nezimbi nge-vasoconstriction

Ezinye izimo zezempilo nemithi kungadala i-vasoconstriction engavamile. Lokhu kungaholela ezinkingeni zezempilo kuya ngokuthi lokhu kwenzeka kuphi nokuthi isikhathi esingakanani.

Unhlangothi

IVasoconstriction ebuchosheni noma ebuchosheni be-vasospasm ingaholela ekushayweni unhlangothi noma ukulimala okufana nentambo. Lokhu kungenzeka ngemuva kokuphuma kwegazi ebuchosheni ngenxa yokuqhekeka noma ukuhlinzwa komthambo wegazi. Umthambo wegazi uyaqaqamba noma unciphe ukuzama ukonga igazi. Lokhu kunciphisa ukunikezwa kwegazi ne-oxygen engxenyeni yobuchopho.

Izimpawu zesifo sohlangothi se-cerebral vasospasm zifaka:

  • ubuhlungu obukhulu bekhanda
  • isiyezi, ukulahlekelwa ibhalansi
  • ukuba ndikindiki noma ubuthakathaka ohlangothini olulodwa lobuso nomzimba
  • kunzima ukukhuluma
  • kunzima ukubona kwelinye noma womabili amehlo
  • ukuhamba kanzima

Funda kabanzi ngalokho okufanele ukwenze ukuze uthole izimpawu zesifo sohlangothi futhi ubone izimpawu zesifo sohlangothi ezihlukile kwabesifazane.

Isimo sikaRaynaud

Isimo sikaRaynaud senza ukuthi ezinye izindawo zomzimba, njengeminwe nezinzwane, zizwe zibande noma zibe ndikindiki. Kulesi simo, imithambo yegazi emincane ehambisa igazi kulezi zindawo iyashayana noma incane. Lokhu kukhawulela ukuthi lingakanani igazi elingafinyelela kulezi zindawo ezingaphandle.

Isimo sikaRaynaud singathinta nekhala, izindebe, izindlebe, nezingono. Kungabangelwa ukuhlala emakhazeni kaningi kakhulu. Lokhu kungenzeka kubantu abasebenza ngaphandle ezindaweni ezibandayo noma abachitha isikhathi esiningi e-ice rink, njengama-ice skaters, abadlali be-hockey, nabashayeli beZamboni.

Lesi simo asiyona ingozi, kodwa singase singakhululeki. Kwezinye izimo, into kaRaynaud ingakhuphula ubungozi bokutheleleka kwesikhumba kanye nokuphulukiswa kwamanxeba kancane ezindaweni ezithintekile. Lokhu kwenzeka ngoba ukugeleza kwegazi okujwayelekile kuyadingeka ukuthwala umoya-mpilo, izakhamzimba, namaseli omzimba alwa nokutheleleka kuwo wonke umzimba. IVasoconstriction inciphisa ukujikeleza kwegazi.

Ukubuyiselwa emuva kwe-cerebral vasoconstriction syndrome

Reversible cerebral vasoconstriction syndrome (RCVS) uhla lwezifo ezibangelwa yi-vasoconstriction ebuchosheni. Iyahlehliswa ezimweni eziningi. Uzolulama ngokuphelele ezinyangeni.

Ezimweni ezimbi kakhulu, i-RCVS ingaholela ekushayweni unhlangothi. Lokhu kwenzeka lapho imithambo yegazi incipha kakhulu noma isikhathi eside kakhulu futhi inqamula ukugeleza kwegazi nomoya-mpilo ezingxenyeni zobuchopho.

I-RCVS kwesinye isikhathi ingavela ezinganeni. Kungabangela umfutho wegazi ophakeme, ubuhlungu bekhanda, nesifo sohlangothi. Kungabangelwa yimiphumela emibi yemithi. Lokhu kufaka phakathi izidakamizwa zamakhemikhali zomdlavuza wamehlo nobuchopho ezinganeni nasezinganeni.

Izimpawu ze-RCVS zifaka:

  • ngokuzumayo, ikhanda elibuhlungu
  • izinguquko embonweni
  • isithuthwane
  • kunzima ukukhuluma
  • kunzima ukuqonda inkulumo
  • ubuthakathaka, imvamisa ohlangothini olulodwa lomzimba

Kwenzeka kanjani i-vasoconstriction

Imisipha ebushelelezi - uhlobo lwemisipha ezindongeni zemithambo yegazi - ayikwazi ukulawulwa ngokuzithandela njengemisipha yamathambo ezithweni zakho. Imithambo yegazi ilawulwa ngokuzenzakalela yizimpawu zamakhemikhali emzimbeni ezitshela imisipha ebushelelezi ukuthi inciphise noma yandise (yanule).

Izithunywa zamakhemikhali ezinzwa namahomoni atshela imithambo yegazi ukuthi icindezeleke ihlanganisa:

  • norepinephrine
  • epinephrine
  • i-angiotensin II
  • i-vasopressin

Imithambo yegazi nemithambo (imithambo emincane) inezindonga zemisipha. Ziyimithambo yegazi eyinhloko ebandakanyeka ku-vasoconstriction. Imithambo nayo ingancipha. Ama-capillaries yimithambo yegazi emincane, enezindonga ezincanyana engakwazi ukuminyanisa.

IVasoconstriction empilweni yakho

IVasoconstriction yemithambo yegazi iyingxenye yemvelo yomzimba wakho yokulinganisa izinhlelo zayo. IVasoconstriction iyadingeka ukusiza ukugcina ukuhamba kwegazi okunempilo nokugcina izinga lokushisa komzimba wakho lingabandi kakhulu. Ingakhuphula nomfutho wegazi lapho kudingeka.

Eminye imithi ilingisa izimpawu zemvelo zomzimba wakho ukudala i-vasoconstriction. Lokhu kungasindisa impilo. Isibonelo, izidakamizwa ze-vasoconstriction zingamisa ukucindezelwa kwegazi ukuthi kwehle kakhulu ngesikhathi sokuphendula okubi kakhulu futhi kunciphise ukulahleka kwegazi ekulimaleni.

Khuluma nomhlinzeki wezokunakekelwa kwezempilo uma unemibuzo mayelana nomfutho wegazi, ukushaya kwenhliziyo, noma ezinye izimpawu ezinjengekhanda.
