Ngaba i-vasoconstriction eqhelekileyo?

"UVaso" ngenene uthetha umthambo wegazi. I-Vasoconstriction iyancipha okanye iyancipha kwimithambo yegazi. Kuyenzeka xa izihlunu ezigudileyo kwiindonga zemithambo yegazi ziqinisa. Oku kwenza ukuba umthambo wegazi uvuleke ube mncinci. IVasoconstriction inokubizwa ngokuba yi-vasospasm.

IVasoconstriction yinkqubo eqhelekileyo. Inceda ukugcina umzimba wakho usempilweni.

IVasoconstriction inokwenzeka kwi:

• uzinzise uxinzelelo lwegazi okanye unyuse uxinzelelo lwegazi
• ukunciphisa ukulahleka kobushushu bomzimba kumaqondo obushushu abandayo
• lawula indlela elisasazwa ngayo igazi emzimbeni wakho wonke
• thumela izondlo-mzimba kunye neoksijini kumalungu azifunayo
• khusela umzimba wakho kwigazi nakwilahleko yolwelo

Kwelinye icala, i-vasoconstriction engaqhelekanga inokubangela iimeko ezithile zempilo. Oku kubandakanya uxinzelelo lwegazi oluphezulu kunye nentloko ebuhlungu. Ngamanye amaxesha, ukunciphisa kakhulu inqanawa yegazi kunokuba sisiphumo esibi secandelo leziyobisi kunye nokutya, njengecaffeine kunye netyuwa.

Funda ukuze ufunde malunga nezizathu ze-vasoconstriction kunye nendlela ezichaphazela ngayo umzimba wakho.

IVasoconstriction kunye noxinzelelo lwegazi

IVasoconstriction inciphisa umthamo okanye indawo ngaphakathi kwimithambo yegazi echaphazelekayo. Xa umthamo wempahla yegazi wehlisiwe, ukuhamba kwegazi kuyancitshiswa. Ngexesha elifanayo, ukuxhathisa okanye amandla okuphuma kwegazi kuphakanyisiwe. Oku kubangela uxinzelelo lwegazi oluphezulu. Uxinzelelo lwegazi olunganyangekiyo (uxinzelelo lwegazi) kunokukhokelela kwiimeko zempilo ekuhambeni kwexesha, njengokulahleka kombono, ukubetha, okanye intliziyo eyonakeleyo.

Ukuchasana ne-vasoconstriction yi-vasodilation. Ngeli xesha ke xa imithambo yegazi ikhululeka kwaye iphangalala, ukwanda kokuhamba kwegazi kunye nokuhla koxinzelelo lwegazi.

Cinga nge-vasoconstriction njengokusela ngengca encinci. Kuthatha amandla okutsala ngaphezulu ukuthatha ithamo. Xa kuthelekiswa, i-vasodilation ifana nokusela isiselo ngokulula nangokukhawuleza ngomququ obanzi.

I-vasoconstriction engaqhelekanga inokubangela okanye yenze uxinzelelo lwegazi lube mandundu. Uxinzelelo oluphezulu lwegazi kunokunyusa umngcipheko wesifo sentliziyo kunye nokufa icala. Ezinye iimeko zempilo kunye neziyobisi zinokubangela i-vasoconstriction eninzi kakhulu okanye yenze ukuba yenzeke kwiindawo ezingafanelekanga, ezinje ngamalungu engqondo.

Ukutya okubangela i-vasoconstriction

Ukutya okuphezulu kwi-sodium kunokubeka uxinzelelo kwimithambo yakho yegazi, kubangele ukuba baxinane. Ukuba ukhathazekile ngoxinzelelo lwegazi, kunqande okanye kunciphise oku kutya kulandelayo:

• ukutya okupakishwe ngokukhawuleza
• Dlulisa inyama
• iisobho ezisemathinini

Utywala bunokunyusa uxinzelelo lwegazi, ithi iMayo Clinic.

Yitya oku kutya kwe-13 ukunciphisa uxinzelelo lwegazi.

IVasoconstriction kwimigraines kunye neentloko

IVasoconstriction inokunceda ukunciphisa kwaye kubangela migraine kunye neentloko.

Xa i-vasoconstriction inceda iintloko

Ukwandiswa kwemithambo yegazi entlokweni kunokususa i-migraine okanye iintlungu zentloko. Amayeza okunyanga olu hlobo lweentlungu zihlala zisebenza ngokubangela i-vasoconstriction. Oku kunceda ukuba imithambo yegazi icuthe kwaye imise ukuhamba kwegazi okungaphezulu.

Ezinye iintloko zentloko kunye ne-migraine ziqulethe i-caffeine ngesi sizathu.

Xa i-vasoconstriction inokubangela iintloko

Kwelinye icala, i-caffeine eninzi inokubangela ukuba i-vasoconstriction egqithileyo kwingqondo. Oku kunokubangela i-migraine okanye intloko. I-American Migraine Association icacisa ukuba oku kunokwenzeka ngenxa yokuba umzimba uxhomekeke kwi-caffeine. Iimpawu zokurhoxa kwikofu kunye nonyango lwentloko zibandakanya iintlungu zentloko, isicaphucaphu kunye nokudinwa.

IVasoconstriction kukothuka

Umothuko ligama eliqhelekileyo lokuphendula komzimba kwinani leemeko ezingxamisekileyo ezahlukeneyo. Zonke ezi meko zibangela uxinzelelo lwegazi olusezantsi. Impendulo yokuqala yomzimba kukukhusela ingqondo, intliziyo kunye nemiphunga. Ukwenza oku ngokunciphisa imithambo yegazi ezandleni, ezinyaweni, nasemilenzeni.

Le vasoconstriction engxamisekileyo inyusa uxinzelelo lwegazi okwethutyana. Inceda ukugcina igazi lihamba liye kumalungu akho afunekayo- amalungu afunekayo ebomini.

Umothuko unokwenzeka ngenxa:

• uguquko (u-anaphylactic shock)
• usulelo lwe-septic (ibhaktiriya, intsholongwane, okanye ukungunda)
• ukuhlaselwa yintliziyo
• isifo sentliziyo
• iswekile esezantsi yegazi
• ihlwili legazi
• ukulahleka kwegazi elinzima (ngaphakathi okanye ngaphandle)
• ukulahleka kakhulu kwamanzi (ukungabikho kwamanzi, ukuhlanza, isifo sohudo)
• Ukutsha kakhulu
• ukwenzakala emqolo
• hypothyroidism eqatha

Amayeza abangela i-vasoconstriction

IVasoconstrictor okanye amayeza okucinezela anceda ukunciphisa uxinzelelo lwegazi kunye nezinye iimpawu. Ezi ziyobisi zingasetyenziselwa ukunyusa uxinzelelo lwegazi xa umntu othukile, opha kakhulu, okanye eneempendulo ezimbi.

Amanye amayeza amiselweyo abangela i-vasoconstriction ukunceda ukunciphisa ukudumba, ukudumba, okanye ukopha kakhulu. Umzekelo, ukuphuma kweempumlo kunokumiswa ngesiyobisi se-vasoconstrictor.

Amayeza eVasoconstriction abandakanya:

• I-alpha-adrenoceptor agonists
• Iimpawu ze-vasopressin
• epinephrin
• norepinephrin
• I-phenylephrine (i-PE edibeneyo)
• dopamine
• dobutamine
• migraine kunye nonyango lwentloko (i-serotonin 5-hydroxytryptamine agonists okanye i-triptans)

Ezinqabileyo kunye neemeko ezinzima zempilo kunye ne-vasoconstriction

Ezinye zeemeko zempilo kunye namayeza kunokubangela i-vasoconstriction engaqhelekanga. Oku kunokukhokelela kwiingxaki zempilo kuxhomekeke ekubeni oku kwenzeka phi kwaye ixesha elingakanani.

Ukubetha

I-Vasoconstriction kwingqondo okanye kwi-vasospasm ye-cerebral ingakhokelela ekubetheni okanye kwingozi efana ne-strokel. Oku kunokwenzeka emva kokuphuma kwegazi kwingqondo ngenxa yokuqhekeka kwegazi okanye uqhaqho. Umthambo wegazi ukopha okanye unciphise ukuzama ukugcina igazi. Oku kunciphisa ukunikezelwa kwegazi kunye neoksijini kwinxalenye yengqondo.

Iimpawu zesifo se-cerebral vasospasm stroke zibandakanya:

• iintlungu eziqatha zentloko
• isiyezi, ukulahleka kwemali eseleyo
• Ukuba ndindisholo okanye ubuthathaka kwelinye icala lobuso nomzimba
• kunzima ukuthetha
• ubunzima bokujonga kwelinye okanye omabini amehlo
• ubunzima bokuhamba

Funda ngakumbi malunga nokwenza ntoni ngeempawu zestroke kunye nokuqonda iimpawu zestroke ezikhethekileyo kubafazi.

Into kaRaynaud

Into kaRaynaud ibangela ukuba ezinye iindawo zomzimba, ezinjengeminwe kunye neenzwane, zive ukuba zibanda okanye zibandindisholo. Kule meko, imithambo yegazi encinci ebonelela ngegazi kwezi ndawo ziyangxama okanye zincinci. Oku kuthintela ukuba lingakanani igazi elinokufikelela kwezi ndawo zingaphandle.

Into kaRaynaud inokuchaphazela impumlo, imilebe, iindlebe kunye neengono. Inokubangelwa kukuhlala kubanda rhoqo. Oku kunokwenzeka kubantu abasebenza ngaphandle kwimimandla ebandayo okanye abachitha ixesha elininzi kwindawo erinki, ezinje nge skating skaters, abadlali be hockey, kunye nabaqhubi be Zamboni.

Le meko ayinabungozi, kodwa inokungonwabi. Ngamanye amaxesha, into kaRaynaud inokunyusa umngcipheko wosulelo lolusu kunye nokupholisa amanxeba kancinci kwiindawo ezichaphazelekayo. Oku kwenzeka ngenxa yokuba ukuhamba kwegazi okuqhelekileyo kuyafuneka ukuphatha ioksijini, izakhamzimba, kunye nosulelo-lokulwa iiseli zomzimba zokuzikhusela emzimbeni wonke. IVasoconstriction inciphisa ukujikeleza kwegazi.

Ukubuyela umva kwesifo se-vasoconstriction syndrome

Ukubuyela umva kwi-cerebral vasoconstriction syndrome (RCVS) luluhlu lweengxaki ezibangelwa yi-vasoconstriction kwingqondo. Iyahlengahlengiswa kwiimeko ezininzi. Uya kuchacha ngokupheleleyo ngaphakathi kweenyanga.

Kwiimeko ezinzima, i-RCVS inokukhokelela ekubetheni. Oku kwenzeka xa imithambo yegazi incinci kakhulu okanye ixesha elide kwaye isika ukuhamba kwegazi kunye neoksijini kwiindawo ezithile zobuchopho.

I-RCVS ngamanye amaxesha inokwenzeka kwiintsana. Ingakhokelela kuxinzelelo lwegazi oluphezulu, iintlungu zentloko kunye nokubetha. Inokubangelwa ziziphumo ebezingalindelekanga zamayeza. Oku kubandakanya amayeza e-chemotherapy kwiliso kunye nomhlaza womhlaza ebantwaneni nasebantwaneni.

Iimpawu ze-RCVS zibandakanya:

• ngequbuliso, intloko ebuhlungu
• utshintsho kumbono
• ukuxhuzula
• kunzima ukuthetha
• ubunzima bokuqonda intetho
• ubuthathaka, ihlala kwicala elinye lomzimba

I-vasoconstriction yenzeka njani

Imisipha egudileyo - uhlobo lwezihlunu kwiindonga zemithambo yegazi - ayinakulawulwa ngokuzithandela njengezihlunu zamathambo emilenzeni yakho. Imithambo yegazi ilawulwa ngokuzenzekelayo ziimpawu zemichiza emzimbeni ezixelela izihlunu ezigudileyo ukuba zinciphise okanye zenze banzi (zenze banzi).

Abathunywa bemichiza yemithambo-luvo kunye neehomoni ezixelela imithambo yegazi ukuba icuthe kubandakanya:

• norepinephrin
• epinephrin
• angiotensin II
• ivasopressin

Iirriyi kunye neearterioles (iirriyitha ezincinci) zineendonga zezihlunu. Ziyimithambo yegazi ephambili ebandakanyeka kwi-vasoconstriction. Imithambo iyakwazi nokuxinana. IiCapillaries zincinci, imithambo yegazi ebiyelweyo engenakunqanda.

IVasoconstriction ebomini bakho

IVasoconstriction yemithambo yegazi yinxalenye yendalo yomzimba wakho yokulinganisa iinkqubo zayo. I-Vasoconstriction iyafuneka ukunceda ukugcina ukuhamba kwegazi okusempilweni kunye nokugcina ubushushu bomzimba wakho kubanda kakhulu. Inokunyusa uxinzelelo lwegazi xa kufuneka njalo.

Amanye amayeza alinganisa imiqondiso yendalo yomzimba wakho ukuba ibangele i-vasoconstriction. Oku kunokusindisa ubomi. Umzekelo, iziyobisi ze-vasoconstriction zinokumisa uxinzelelo lwegazi ekubeni lwehle kakhulu ngexesha lokungalungelelani komzimba kunye nokunciphisa ukulahleka kwegazi ekwenzakaleni.

Thetha nomboneleli wezempilo ukuba unemibuzo malunga noxinzelelo lwegazi, izinga lentliziyo, okanye ezinye iimpawu ezinjengeentloko.
