Ubusazi ngemithambo yegazi emangalisayo "egcinayo" emizimbeni yethu? (Ukujikeleza kwegazi okudibeneyo) Masithethe!

Namhlanje siza kuthetha ngento emangalisayo nebalulekileyo emizimbeni yethu . Khawucinge nje, ukuba indlela ephambili oyithathayo ivaleka ngequbuliso, kubaluleke kangakanani ukuba nezinye iindlela ezincinci ezisecaleni onokuzihamba. Ngokufanayo, emizimbeni yethu, ukuba umthambo wegazi oyintloko (umthambo wegazi) uvaliwe okanye wonakele, kukho inkqubo "eyahlukileyo" okanye "eyogcino" yemithambo yegazi engasetyenziswa endaweni yoko. Oku kubizwa ngokuba yi-Collateral Circulation kumayeza . Ngamafutshane, oku kufana nenkqubo yendalo "yokudlula" emizimbeni yethu.

Ngoko ke, yintoni le ndlela yokuhambisa igazi (i-collateral circulation)?

Ngamafutshane, ukujikeleza kwegazi okudibeneyo yinkqubo yemithambo yegazi eyongezelelweyo okanye "yogcino" emzimbeni wakho. Le yimithambo yegazi enceda ekuguquleni igazi ukuba umthambo wegazi oyintloko, njengomthambo okanye umthambo, uvalekile okanye wonakele ngesizathu esithile. Oku kufana nendlela xa indlela enkulu esixekweni ivaliwe, iimoto zithatha iindlela ezisecaleni. Ngokuba negazi lihamba ngale ndlela inye, amalungu abalulekileyo anokuqhubeka nokufumana ioksijini kunye nezondlo azidingayo.

Le yindlela emangalisayo yokuzikhusela emizimbeni yethu. Khawuthelekelele ukuba bekuya kwenzeka ntoni ukuba umthambo omkhulu wegazi ubungavalwa ngequbuliso ngaphandle kwezi ndlela zimbi!

Isebenza njani le ndlela yokujikeleza kwe-collateral? Iyamangalisa, akunjalo?

Ewe, iyamangalisa ngokwenene. Le nkqubo (yeCollateral Circulation ) isebenza ngeendlela ezahlukeneyo.

• Imithambo yegazi emincinci esele ikho: Sinenethiwekhi yemithambo yegazi emincinci kakhulu, emincinci eqhagamshelwe kwimithambo yegazi yethu ephambili. Kwiimeko eziqhelekileyo, le ayisebenzi kangako, njengeendlela ezincinci ezingasetyenziswayo. Nangona kunjalo, xa ukuhamba kwegazi ukuya kwimithambo yegazi emikhulu kuphazamiseka, umzimba uyakuqonda oku. Emva koko, le mithambo yegazi mincinci "engalaliyo" iyanda kancinci kancinci, ivuleke, ize iqale ukuthwala igazi elingakumbi.

• Ukwakheka kwemithambo yegazi emitsha (i-Angiogenesis): Ngamanye amaxesha, xa umthambo wegazi omkhulu uvaleka kancinci kancinci, umzimba wethu uyakuva oku. Xa ufumana uphawu lokuba "akukho gazi laneleyo elihamba apha," umzimba uqala ukwenza imithambo yegazi emitsha, emincinci. Le nkqubo ibizwa ngokuba yi-angiogenesis . Le mithambo mitsha inceda ekuthwaleni igazi kwindawo evalekileyo.

• Isiphumo somthambo: Ubusazi na ukuba umthambo we-aerobic rhoqo , njengokubaleka okanye ukuhamba ngokukhawuleza, kunokunceda ukuphucula ukuhamba kwegazi kule mithambo yegazi mitsha?Ivuselela i-angiogenesis. Oku kuthetha ukuba umthambo ungayomeleza le nkqubo "yokubuyisela".

Ngoko ke, le yindlela umzimba wethu ozama ngayo ukumelana nokuphazamiseka kokujikeleza kwegazi .

Ixhaphake kangakanani le ndlela yegazi eyahlukileyo (i-collateral circulation)? Ngaba wonke umntu unayo?

Sonke sizalwa sinezinga elithile lokujikeleza kwegazi okuzinzileyo . Nangona kunjalo, ubungakanani, inani, kunye nokusebenza kakuhle kwale mithambo yegazi eyongezelelweyo kunokwahluka kumntu nomntu. Abanye abantu banenkqubo ephuhlileyo kakhulu, ngelixa abanye bengenayo iphuhlileyo kangako. Iyahluka kumntu nomntu.

Kukho iintlobo ezintathu eziphambili zale mibhobho yegazi eyahlukileyo:

• Imithambo yegazi: Le yimithambo yegazi emikhulu ethwala igazi elineoksijini eninzi ukusuka entliziyweni ukuya emzimbeni wonke.
• IiCapillaries: Ezi zimithambo yegazi emincinci kakhulu. Zisasazeke njenge-mesh. Zihambisa ioksijini kunye nezondlo kwiiseli kwaye ziqokelela inkunkuma efana nekhabhoni diokside.
• Imithambo: Le yimithambo yegazi ethwala igazi elinomoya-mpilo ophantsi, elityebileyo kwi-carbon dioxide, elibuyela entliziyweni lisuka kwiindawo ezahlukeneyo zomzimba.

Ngoko ke zonke iintlobo ezintathu zemithambo yegazi, imithambo yegazi, imithambo yegazi, kunye nee-capillaries, zinokusebenza njengezi ndlela zokuhambisa igazi ezizezinye.

Kuphantsi kweziphi iimeko zempilo apho olu jikelezo lwegazi olubalulekileyo lubaluleke kakhulu khona?

Le nkqubo (yeCollateral Circulation) ingasetyenziswa kwaye incede kwiimeko ezahlukeneyo zonyango ezithintela ukuhamba kwegazi, oko kukuthi, ukunciphisa ukuhamba kwegazi ngemithambo yegazi. Nazi imizekelo embalwa:

• I-atherosclerosis : Oku kwenzeka xa amafutha kunye ne-cholesterol ziqokelelana ngaphakathi kweendonga zemithambo yegazi, zinciphisa imithambo yegazi, zivale ukuhamba kwegazi.
• Isifo seMitha yeCoronary: Ukuhlaselwa yintliziyo kubangelwa kukuvaleka kwemithambo yentliziyo ehambisa igazi entliziyweni.
• I-Ischemic Stroke: Le meko yenzeka xa umthambo ohambisa igazi engqondweni uvalekile okanye kwakheka ihlwili.
• Isifo seMithambo yoMzimba (i-PAD): Esi sifo sibangelwa kukuncitshiswa kwemithambo yegazi ehambisa igazi, ingakumbi emilenzeni. Olunye uphawu lwesi sifo ziintlungu emilenzeni xa uhamba.

Kodwa nantsi into ebaluleke kakhulu ekufuneka uyikhumbule! Le nkqubo (yeCollateral Circulation) isoloko ichaphazeleka kukuncipha kokunikezelwa kwegazi (i-Ischemia) okubangelwa zezi meko.Akunakuthintelwa ngokupheleleyo. Kuba, ngaphambi kokuba umthambo wegazi oyintloko uvalwe ngokupheleleyo, ezi ndlela zingezinye kufuneka zikhule ngokukhawuleza ngokwaneleyo kwaye zikwazi ukuthwala igazi elaneleyo. Ke ngoko, ukuba uneemeko ezinjalo, nokuba unendlela efanelekileyo yokuhambisa igazi, ngokuqinisekileyo kufuneka ufune unyango. Olu luncedo nje kuphela, alusosisombululo esipheleleyo.

Ihlala ixesha elingakanani le nkqubo yokusasazwa kwemali?

Xa le nkqubo (yokujikeleza kwegazi) isebenza, loo mithambo yegazi mincinci iyanda kancinci kancinci ize iqalise ukuthwala igazi elingakumbi. Le mithambo yegazi ikhulisiweyo inokukwazi ukubonelela ngegazi eliqhelekileyo kangangeenyanga, mhlawumbi neminyaka.

Nangona kunjalo, ngokuhamba kwexesha, ingakumbi njengoko sikhula, le mithambo yegazi eyahlukileyo inokuncipha kancinci kancinci, okanye iqale ukuba ncinci. Le nkqubo ibizwa ngokuba yi-rarefaction . Le meko ixhaphake kakhulu kubantu abanesifo sentliziyo . Xa le mithambo yegazi eyahlukileyo incipha, ukusebenza kwayo kuncipha. Emva koko, ukuba umthambo wegazi omkhulu uvalekile kwakhona, iimpawu zinokwenzeka.

Zeziphi iindawo zomzimba ezifumaneka kuzo ezi mithambo yegazi eyahlukileyo (i-collateral circulation)?

Ezi nkqubo zokujikeleza kwegazi ezizezinye zinokufumaneka kwiindawo ezahlukeneyo zomzimba wethu. Umzekelo:

• Isisu
• Iingalo
• Ingqondo
• Iinyawo nemilenze
• Entliziyweni
• Imiphunga

Enyanisweni, le (Collateral Circulation) yindlela esetyenziswa ngumzimba ukoyisa umqobo ekuhambeni kwegazi. Nangona kunjalo, njengoko bekutshiwo ngaphambili, le asiyondlela ingenabungozi enokuthintela ngokupheleleyo umonakalo obangelwa zizifo ezifana nestroke kunye nezifo ezifana ne- (PAD) . Ayinakukuthintela ngokupheleleyo ukuhlaselwa yintliziyo okanye istroke. Nangona kunjalo, kwezinye iimeko, inokuba luncedo kakhulu, kwaye inokunceda nokusindisa ubomi.

Zithini iithemba zoku kwixesha elizayo?

Abaphandi bezonyango bayaqhubeka nokufunda oku (collateral circulation) ngomdla omkhulu. Ngokukodwa, uphando lwenziwa malunga nokuba imithambo yokwenziwa edibeneyo ingenziwa kwaye isetyenziswe na. Ukuba into enjalo iphumelele, kuya kuba nokwenzeka ukwandisa amandla endalo omzimba okumelana nezifo ezahlukeneyo eziphazamisana nokujikeleza kwegazi. Elo lithemba elikhulu.

Ngoko ke, zeziphi izinto ezibalulekileyo ekufuneka sizikhumbule koku? (Umyalezo Wokubuyela Ekhaya)

Kulungile, masikhumbule ezinye zezona zinto zibalulekileyo esikhe sathetha ngazo (iCollateral Circulation) :

• Ukujikeleza kwegazi nge-Collateral yinkqubo yendalo "yokuxhasa" imithambo yegazi emzimbeni wethu.Ukuba umthambo wegazi omkhulu uvalekile, uyanceda.
• Le yindlela yokuzikhusela yomzimba. Ngamanye amaxesha inokuba luncedo kakhulu kwaye isindise nobomi.
• Ukuzilolonga rhoqo kunceda le mithambo yegazi eyahlukileyo ikhule.
• Nangona kunjalo, esi asisosisombululo sipheleleyo kwizifo. Ukuba unemeko efana ne (Atherosclerosis) , (Coronary Artery Disease) , (Stroke Risk), okanye (PAD) , ngokuqinisekileyo kuya kufuneka ufune iingcebiso zonyango kunye nonyango.
• Ukusebenza kwezi ndlela zingezinye kunokuncipha xa ukhula okanye xa uneengxaki ezithile zempilo.
• Ukugcina indlela yokuphila esempilweni , ingakumbi ukutya ukutya okunempilo kwentliziyo kunye nokuzilolonga, kunceda ukugcina le nkqubo eyahlukileyo, kunye nayo yonke inkqubo yokujikeleza kwegazi, isempilweni.

Ngoko ke, imizimba yethu iyamangalisa ngokwenene, akunjalo? Kuyamangalisa indlela abayila ngayo iinkqubo ezintsonkothileyo kangaka ukuze bazikhusele. Kodwa, nangona benceda ezo ndlela zendalo zokuzikhusela, kubalulekile nokuba sikhathalele impilo yethu.

Imithambo yegazi eyahlukileyo , iindlela ezongezelelweyo zegazi, Ukujikeleza kwegazi okudibeneyo, ukujikeleza kwegazi, isifo sentliziyo, ukuvaleka kwemithambo yegazi, i-Angiogenesis
