Cabanga ukuthi kukhona isiminyaminya esikhulu sezimoto emgwaqweni omkhulu ohlala uwuthatha, futhi umgwaqo uvaliwe ngokuphelele. Wenzani-ke? Isikhathi esiningi, sibuza umuntu owazi kahle indawo noma sihlole i-Google Maps, bese sithatha umgwaqo omncane oseceleni ukuze sifike lapho siya khona ngaphandle kokubhajwa, akunjalo? Ngokumangalisayo, yilokhu kanye okwenzekayo emzimbeni wethu. Uma umthambo wegazi omkhulu emzimbeni wethu, okungukuthi, umthambo wegazi, uvaliwe ngesizathu esithile, umzimba udala uhlelo 'lwemigwaqo eseceleni' esizokhuluma ngalo kulesi sihloko namuhla.
Kalula nje, kuyini ukujikeleziswa kwemali okuhlanganisiwe?
Leli gama lingase lizwakale liyinkimbinkimbi kancane, kodwa empeleni lilula kakhulu. Ukujikeleza kwegazi okuhlangene yinqubo lapho, lapho umthambo omkhulu wegazi (umthambo noma umthambo) emzimbeni wethu uvaleka noma wonakala, kwakheka uhlelo oluhlukile, noma "lokusekelayo" lwemithambo yegazi ukuze luthwale igazi.
Kalula nje, lolu uhlelo lwemvelo 'lokudlula' emzimbeni wethu. Njengoba nje ngishilo ngaphambili, lapho umgwaqo omkhulu uvaliwe, sifuna imigwaqo eseceleni, umzimba udala nemigwaqo emisha eseceleni yokugeleza kwegazi. Lena indlela emangalisayo yokuzivikela emzimbeni wethu.
Lolu hlelo lwe-bypass lwemvelo lusebenza kanjani?
Manje ungase ucabange, "Ngakho-ke le migwaqo eseceleni idalwe ngokuzumayo?" Empeleni, lokhu kungenzeka ngezindlela ezimbili.
1. Ukwanda kwemithambo yegazi emincane ekhona: Umzimba wethu unenethiwekhi yemithambo yegazi emincane kakhulu, evame ukusetshenziswa exhunywe emithanjeni yegazi yethu eyinhloko. Lapho umthambo oyinhloko uqala ukuvaleka, umzimba uyasiqaphela lesi simo. Bese kuthi, ngokusekelwe ezimpawini ezivela ebuchosheni nasezinhlelweni ezahlukene emzimbeni, leyo mithambo yegazi emincane iqala ukukhula kancane kancane futhi ivuleke. Bese kuthi, igazi elalingakwazi ukudlula emthambo oyinhloko liqale ukuhamba ngale migwaqo eseceleni esanda kwandiswa.
2. Ukwakheka kwemithambo yegazi emisha: Ngezinye izikhathi, ikakhulukazi lapho umthambo wegazi omkhulu uvaleka kancane kancane, umzimba uqala ukudala imithambo yegazi emisha. Kwezokwelapha, le nqubo siyibiza ngokuthi i-angiogenesis . Umzimba uyaqaphela ukuthi inani legazi eliya esithweni liyancishiswa. Ngaleso sikhathi, leso sitho ngokwaso sikhipha izimpawu zamakhemikhali, zithi, "Asinalo igazi elanele, yenzani imigwaqo emisha." Ngokufanelekile, le mithambo yegazi emisha iyakhiwa.
Ikakhulukazi, ucwaningo luthole ukuthi ukuzivocavoca njalo kwe-aerobic , njengokugijima, ukuhamba ngokushesha, nokubhukuda, kukhuthaza ukwakheka kwemithambo yegazi emisha. Yingakho ukuzivocavoca kuhle kakhulu enhliziyweni.
Ingabe wonke umuntu unale mithambo yegazi eyengeziwe emizimbeni yakhe?
Yebo, sonke sizalwa sinesistimu ethile yemithambo yegazi ehambisanayo. Kodwa-ke , inani lale mithambo emzimbeni womuntu ngamunye kanye nosayizi wayo kungahluka kumuntu nomuntu . Kuncike ezintweni eziningi, okuhlanganisa izakhi zofuzo nendlela yokuphila.
Le mithambo yegazi eyengeziwe ingaba ngeyama-three izinhlobo eziyinhloko.
| Uhlobo lomthambo wegazi | Kalula nje... |
|---|---|
| Imithambo yegazi | Lezi yimithambo emikhulu eyinhloko ethwala igazi elinomoya-mpilo lisuka enhliziyweni liye emzimbeni wonke. |
| Imithambo yegazi | Lezi yimithambo yegazi eletha igazi elisetshenzisiwe (igazi elingenawo umoya-mpilo) lisuka ezingxenyeni zomzimba libuyele enhliziyweni. |
| Ama-Capillaries | Lena yimithambo yegazi emincane kakhulu nebuthakathaka kakhulu. I-oksijini nezakhamzimba kuyashintshaniswa kusuka egazini kuya emaseli ngalezi. |
Kukuziphi izinhlobo zezifo lapho lokhu kujikeleza kwegazi okubalulekile khona?
Lolu hlelo lwemvelo lokudlula lungasisiza nganoma yisiphi isimo esivimba imithambo yegazi. Lokhu kubaluleke kakhulu kubantu abanezimo ezilandelayo:
- I-atherosclerosis: Lokhu ukuqina kwemithambo yegazi ngenxa yokuqongelela kwamafutha ne-cholesterol ezindongeni zemithambo yegazi. Kufana nokugqwala okwakheka ngaphakathi kwepayipi lamanzi. Njengoba umthambo wegazi uvaleka kancane kancane, umzimba uba nesikhathi sokwakha imithambo yegazi ehambisanayo.
- Isifo Semithambo Yenhliziyo: Ukuvaleka kwemithambo yegazi ehambisa igazi enhliziyweni. Lesi yisona sizathu esiyinhloko sokuhlaselwa yinhliziyo. Ngisho noma umuntu onesistimu enhle yokusekela ehlaselwa yinhliziyo, umonakalo obangelwe ungancishiswa ngezinga elithile.
- I-Ischemic Stroke: I-stroke ebangelwa ukuvaleka kwemithambo yegazi ehambisa igazi ebuchosheni.
- Isifo Semithambo Engasogwini (i-PAD): Ukuncipha kwemithambo ehambisa igazi, ikakhulukazi emilenzeni. Lokhu kungabangela ubuhlungu emilenzeni lapho uhamba.
Kodwa nansi into ebaluleke kakhulu okudingeka siyiqonde sonke. Lokhu kujikeleza kwegazi okubalulekile akuwona umlingo noma ikhambi lazo zonke izinto . Kumane kuyindlela yokuzivikela yomzimba.
Le mithambo yegazi eyengeziwe ayikwazi ukuvimbela ngokuphelele ischemia , noma ukuncipha kokunikezwa kwegazi esithweni, okubangelwa yilezi zimo. Ngezinye izikhathi, uma umthambo oyinhloko uvalekile ngokuzumayo, uhlelo lwemithambo yegazi eyengeziwe lungase lungakwazi ukunikezela igazi ngokushesha.
Ngakho-ke, uma unesifo esifana nalesi, kufanele nakanjani ubone udokotela wakho futhi uthole ukwelashwa okufanele , kunokuthembela kuphela kulesi simiso semvelo. Lokhu kungaba umehluko phakathi kokuphila nokufa.
Lolu hlelo lwemithambo yegazi olungaphezulu luhlala isikhathi esingakanani?
Uma ukujikeleza kwegazi okuhlanganisiwe sekuqalile, leyo mithambo yegazi eyengeziwe ekhulisiwe ingasiza ekugcineni ukugeleza kwegazi okuvamile emzimbeni izinyanga, ngisho neminyaka.
Kodwa-ke, njengoba siguga, le mithambo yegazi eyengeziwe iyancipha kancane kancane, noma iqala ukuncipha ngobukhulu. Lokhu sikubiza ngokuthi i-rarefaction . Lesi simo singavela ngokushesha kakhulu kubantu abanesifo senhliziyo nemithambo yegazi. Lapho imithambo yegazi eyengeziwe incipha ngale ndlela, ikhono layo lokusiza uma umthambo omkhulu omusha uvalekile nalo liyancipha. Yingakho kuthiwa kufanele sinakekele impilo yethu njengoba siguga futhi sinezinye izifo.
Lolu hlelo lutholakala kuziphi izingxenye zomzimba?
Lolu hlelo lokujikeleza kwegazi oluhlangene lutholakala ezingxenyeni ezahlukene zomzimba wethu. Lolu hlelo lokuvikela lungabonakala noma kuphi lapho kunengozi yokuvaleka kwemithambo yegazi.
| Ingxenye yomzimba | Ukubaluleka |
|---|---|
| Inhliziyo | Kusiza ekunciphiseni umonakalo enhliziyweni ngesikhathi sokuhlaselwa yinhliziyo. |
| Ubuchopho | Kuyasiza ngezinga elithile ukuvimbela ukufa kwamangqamuzana obuchopho uma kwenzeka isifo sohlangothi. |
| Imilenze nezinyawo | Kusiza ekunciphiseni ubuhlungu lapho uhamba kubantu abanesifo semithambo yegazi engaphandle (i-PAD). |
| Izandla | Uma imithambo yegazi ehambisa igazi ezandleni ivaleka, kuyasiza ekugcineni ukusebenza kwesandla. |
| Isisu namaphaphu | Lolu hlelo lusebenza futhi uma kwenzeka ukuvaleka kwemithambo yegazi emikhulu exhumanisa lezi zitho. |
Ngamafuphi, ukujikeleza kwegazi okuhlangene kuyikhono elimangalisayo imizimba yethu enalo lokulwa nomthambo wegazi ovinjiwe. Akuyona indlela engenakugwenywa yokuvimbela ngokuphelele umonakalo ongase uvele ngenxa yokuhlaselwa yinhliziyo noma isifo sohlangothi. Kodwa kwezinye izimo, kungaba ithuluzi eliwusizo nelisindisa impilo.
Abacwaningi bezokwelapha okwamanje baphenya ngamathuba okudala imithambo yegazi yokwenziwa bese beyifakela ezigulini. Uma iphumelela, lolu cwaningo lunganikeza impumuzo enkulu kubantu abaningi abahlushwa izifo zemithambo yegazi esikhathini esizayo.
Umlayezo Wokuya Nawe Ekhaya
- Ukujikeleza kwegazi okuhlangene kuyindlela yemvelo yomzimba wethu 'yokudlula' noma 'yokusekela' imithambo yegazi.
- Umsebenzi wayo ukuhlinzeka ngeminye imizila yokugeleza kwegazi lapho umthambo wegazi omkhulu uvalekile.
- Ukuvivinya umzimba njalo kukhuthaza ukuthuthukiswa kwalesi simiso semvelo sokudlula.
- Nakuba lokhu kuyindlela yokuzivikela ewusizo kakhulu, khumbula ukuthi akuyona ikhambi lokugcina noma ikhambi lezimo ezifana nesifo senhliziyo kanye nesifo sohlangothi.
- Uma unezimpawu zokuvaleka komthambo wegazi, njengobuhlungu besifuba, ubunzima bokuphefumula, noma ubuhlungu emilenzeni yakho lapho uhamba, bona udokotela wakho ngokushesha . Themba izinhlelo zemvelo futhi ugweme ukulibazisa ukwelashwa.
