Oku kunokukhokelela ekuvuseleleni i-vasodilation, njengoko izihlunu ozisebenzisayo zifuna izakha mzimba kunye neoksijini.

Ukudumba

Ukuvuvukala kunokwenzeka ngenxa yeendlela ezahlukeneyo zokulimala, izifo, okanye iimeko. I-Vasodilation yenzeka ngexesha lenkqubo yokuvuvukala ukwenzela ukuvumela ukwanda kokuhamba kwegazi kwindawo echaphazelekayo.

Yiyo le nto ibangela ubushushu kunye nobomvu obuhambelana nokudumba.

Ubushushu

Unee-receptors emzimbeni wakho ezibizwa ngokuba zii-thermoreceptors, ezifumanisa utshintsho kubushushu bommandla wakho.

Xa i-thermoreceptors yakho ithatha ubushushu obuphezulu kwindawo yakho enxulumene nokubanda, i-vasodilation iyakwenzeka.

Oku kuqondisa ukuhamba okuphezulu kwegazi kulusu lwakho kumzamo wokuchitha nayiphi na imfudumalo egqithileyo oyivayo.

Izinto zeVasodilator eziveliswa ngumzimba

Zininzi izinto eziveliswa ngumzimba wakho ezinokukhokelela ekuvuseleleni i-vasodilation.

Eminye imizekelo ibandakanya izinto ezinjenge-nitric oxide kunye ne-carbon dioxide kunye neehomoni ezifana ne-acetylcholine, i-prostaglandins kunye ne-histamine.

Amayeza eVasodilator

Iziyobisi ezibizwa ngokuba yi-vasodilators zinokubangela ukuba imithambo yegazi yakho yandiswe.

Banokusebenza ngokuthe ngqo kwimisipha egudileyo yemithambo yegazi okanye kwinkqubo yakho yemithambo-luvo, eyinxalenye yenkqubo yemithambo-luvo yakho elawula i-vasodilation kunye ne-vasoconstriction.

Yintoni i-vasodilation?

I-Vasodilation kukwandiswa kwemithambo yegazi yakho. Kuyenzeka xa izihlunu ezigudileyo zifunyenwe ezindongeni zemithambo okanye kwimithambo emikhulu ziphumle, ivumela imithambo yegazi ukuba ivuleke ngakumbi.

Oku kukhokelela kukonyuka kokuhamba kwegazi kwimithambo yegazi kunye nokuhla koxinzelelo lwegazi.

Zeziphi iimeko ezibandakanya i-vasodilation?

Kukho iimeko ezahlukeneyo ezinokukhokelela ekuvuseleleni i-vasodilation. Apha ngezantsi, siza kuvavanya eminye imizekelo kwaye sixoxe ngokuba kutheni i-vasodilation ibalulekile.

Iimeko okanye izifo ezibangela ukudumba

I-Vasodilation yinto ebalulekileyo yokuvuvukala. Yonyusa ukuhamba kwegazi ukuya kule ndawo kwaye ikwonyusa ukugcwala, okanye ukuvuza, kweendonga zemithambo yegazi. Zombini ezi zinto zinceda iiseli zokhuselo lomzimba ukufikelela ngokufanelekileyo kwindawo echaphazelekayo.

Ukuvuvukala yinkqubo eyenzelwe ukunceda ukususa imizimba yethu ngabahlaseli bamanye amazwe, kodwa kwezinye iimeko kunokuba yingozi, njengokuphendula okungalunganga nezifo ezingapheliyo.

I-Vasodilation enxulumene nokuvuvukala inokubonwa kwezi meko zilandelayo:

• Ukwenzakala, njengokufumana i-splinter okanye ukukrwela okanye ukujija iqatha
• Usulelo, njengaxa impumlo yakho iba bomvu ize iqaqoko ngexesha lengqele okanye xa inxeba elosulelekileyo libomvu kwaye lishushu ngumphunga
• Ukunyanga komzimba, ezenzeka xa amajoni akho omzimba ephendula kwinto engeyongozi yelinye ilizwe. Imbali idlala indima enkulu ekukhuthazeni i-vasodilation kule meko.
• Izifo ezinganyangekiyo okanye iimeko, ngakumbi ezo apho amajoni omzimba ahlasela iiseli ezisempilweni zomzimba. Eminye imizekelo ibandakanya i-rheumatoid arthritis, i-lupus, kunye ne-bowel disease (IBS). Abantu abanezi meko banokubonisa imiba ngokusebenza kwegazi, kubandakanya ukungasebenzi kakuhle kwe-vasodilation. Oku kunokukhokelela kwiingxaki zentliziyo.

Erythromelalgia

I-Erythromelalgia yimeko enqabileyo enokuchaphazela izandla neenyawo zakho. Iimpawu zingabandakanya iintlungu ezivuthayo, ukufudumala kunye nokubomvu kwindawo echaphazelekayo.

Uninzi lwabantu abanemeko, iimpawu azihlali rhoqo kodwa endaweni yoko zenzeka rhoqo.

Ngelixa unobangela we-erythromelalgia engaziwa, obunye ubungqina bubonisa ukuba iimpawu zinokubangelwa kukungahambi kakuhle kwe-vasodilation kunye ne-vasoconstriction.

I-Vasodilation kunye ne-hypotension

Inkqubo ye-vasodilation ngokwendalo ikhokelela ekwehleni koxinzelelo lwegazi. Oku kungenxa yokwandiswa kwemithambo yegazi, ekhokelela ekuhambeni kwegazi okukhulu kwaye ke uxinzelelo oluncinci kwiindonga zemithambo yegazi.

Uxinzelelo lwegazi olusezantsi ngokungaqhelekanga lubizwa ngokuba yi-hypotension. Uxinzelelo lwengqondo alunakubangela ngxaki kwabanye abantu, kodwa kwabanye lunokukhokelela kwiimpawu ezinje ngesiyezi, ukutyhafa, kunye nesicaphucaphu. Amanqanaba aphezulu e-hypotension anokuba sengozini yobomi.

Inani leemeko linokubangela i-hypotension, kubandakanya ukungahambelani komzimba (anaphylaxis), ukulahleka kwegazi, ukomisa amanzi emzimbeni kunye nosulelo olukhulu. Amayeza athile, ngakumbi lawo asetyenziselwa ukunyanga uxinzelelo lwegazi olunokukhokelela kwi-hypotension.

Yintoni enye echaphazela i-vasodilation?

Iindidi ezahlukeneyo zemeko yokusingqongileyo kunye neyakho zinokuba nefuthe kwi-vasodilation, kubandakanya:

Ubushushu

I-Vasodilation yenzeka xa usiva ubushushu obufudumeleyo. Kuyanceda ukuhambisa ukuhamba okuphezulu kwegazi kulusu lwakho ukuze ugcine ubushushu bomzimba wakho kwinqanaba eliqhelekileyo.

Ukuchaphazeleka ixesha elide kumaqondo obushushu aphezulu kunokuchaphazela amandla omzimba wakho wokulawula iqondo lobushushu, okukhokelela kwiimeko ezinje ngokudinwa kobushushu kunye nokubetha kobushushu.

Ukuphakama

Njengoko usiya kwiindawo eziphakamileyo, kukho ioksijini encinci efumanekayo emoyeni ophefumlayo.

Umzimba wakho ekuqaleni uphendula koku kungabikho kweoksijini ngokusebenzisa i-vasodilation, ivumela ukuhamba kwegazi okungaphezulu kwizicubu zakho. Nangona kunjalo, oku kulandelwa yi-vasoconstriction.

I-vasoconstriction ehamba nayo inokukhokelela ekwandeni koxinzelelo lwegazi kunye nokwakha ulwelo kwizicubu ezinje ngemiphunga. Le meko ibizwa ngokuba yi-edema ephezulu ye-pulmonary edema kwaye inokusongela ubomi. Le meko inokunyangwa ngamachiza e-vasodilator okanye oksijini eyongezelelweyo.

Ubudala

Ukwanda kweminyaka kudityaniswa nokwehla kokusebenza kwemithambo yegazi, kubandakanya i-vasodilation. Oku kunokuba negalelo kumngcipheko weziganeko zentliziyo ezinje ngesifo sentliziyo kunye nokubetha.

Ubunzima

Abantu abatyebe kakhulu baye babonwa ukuba banokungasebenzi kakuhle kwi-vasodilation.

Kumntu otyebe kakhulu, imithambo yegazi iyamelana ngakumbi ne-vasodilation, enokuthi ikhokelele kwimiba yentliziyo. Ukwehla kobunzima kunokunceda ukunciphisa ukungasebenzi kakuhle kwi-vasodilation.

Iziyobisi zeVasodilator

Amachiza eVasodilator ngamayeza anokubangela i-vasodilation. Uninzi lunokusebenza ngokuthe ngqo kwimisipha egudileyo efumaneka kwiindonga zemithambo yegazi. Abanye banokuthi basebenze kwinxalenye yenkqubo yemithambo-luvo elawula i-vasodilation kunye ne-vasoconstriction.

Ngenxa yokuba i-vasodilation inciphisa uxinzelelo lwegazi, oogqirha bahlala bemisela i-vasodilators kwiimeko ezinje ngoxinzelelo oluphezulu lwegazi okanye ukusilela kwentliziyo. Ezinye i-vasodilators ziyeza ezinamandla kwaye zinokubangela iziphumo ebezingalindelekanga ezinje ngokubetha kwentliziyo okukhawulezayo, ukugcinwa kwamanzi kunye nokugungxula.

I-Viagra ngumzekelo weziyobisi ezichaphazela i-vasodilation kwaye ayisetyenziswanga ikakhulu kunyango lwegazi. Inceda ekunyangeni ukungasebenzi kakuhle kwe-erectile ngokuchaphazela iindlela zebhayiloji ezikhokelela ekuvuseleleni imisipha egudileyo.

Oku kukhokelela kukonyuka kokuhamba kwegazi ukuya kwilungu lobudoda. Ukusetyenziswa kwesibini kweViagra kunyanga ezinye iindlela zoxinzelelo lwegazi oluphezulu.

Uthini umahluko phakathi kwe-vasodilation kunye ne-vasoconstriction?

IVasoconstriction ichasene ne-vasodilation. Nangona i-vasodilation ikwandiswa kwemithambo yegazi, i-vasoconstriction kukunciphisa imithana yegazi. Kungenxa yokuncipha kwezihlunu kwimithambo yegazi.

Xa i-vasoconstriction isenzeka, ukuhamba kwegazi kwezinye izicwili zomzimba wakho kuyathintelwa. Uxinzelelo lwegazi lwakho luyenyuka.

Ukuthatha

I-Vasodilation yenzeka ngokwendalo emzimbeni wakho ekuphenduleni izinto ezinje ngamanqanaba eoksijini asezantsi, ukwehla kwezakha mzimba ezikhoyo, kunye nokunyuka kobushushu.

Ibangela ukwandiswa kwemithambo yegazi yakho, ethi yona inyuse ukuhamba kwegazi kunye nokunciphisa uxinzelelo lwegazi.

Nangona i-vasodilation yinkqubo yendalo, kukho iimeko ezinokuba yingozi kuzo, ezinje nge-hypotension ebukhali, uguquko, kunye neempendulo ezomeleleyo zokuvuvukala.

Ukongeza, izinto ezinje ngobudala kunye nobunzima zinokuchaphazela kakubi i-vasodilation.

Nangona kunjalo, ukunciphisa i-vasodilation inokuba sisixhobo esibalulekileyo sokunyanga iimeko ezinje ngoxinzelelo oluphezulu lwegazi kunye nokugula okunxulumene nokuphakama okuphezulu.
