Wake wazibuza ukuthi kungani iminwe yakho iphenduka ibe mnyama ngosuku olubandayo kakhulu? Noma ukuthi kungani inhliziyo yakho ishaya ngokushesha futhi umzimba wakho ubanda uma wesaba kakhulu noma ungaphansi kokucindezeleka okukhulu? Namuhla sizokhuluma ngenqubo emangalisayo emzimbeni wethu ebangela konke lokhu. Lokhu kubizwa ngokuthi i-Vasoconstriction kwisayensi yezokwelapha.
Kalula nje, kuyini ukuvaleka kwemithambo yegazi?
Cabanga ngohlelo lwemithambo yegazi emzimbeni wethu njengenethiwekhi yamapayipi amanzi. Lawa mapayipi (imithambo yegazi) azungezwe ungqimba oluncane kakhulu lwemisipha. Uma ngesizathu esithile lo musipha uqina, okungukuthi, ufinyela, isikhala ngaphakathi komthambo wegazi siyancipha. Leyo nqubo yilokho esikubiza ngokuthi i-vasoconstriction .
Kukhona olunye uhlangothi lwalokhu. Okusho ukuthi, imisipha ezungeze imithambo yegazi iyakhululeka, ikhulise imithambo yegazi. Lokhu sikubiza ngokuthi i-vasodilation. Zombili lezi zinqubo zilawulwa uhlelo lwethu lwezinzwa. Umzimba wethu unekhono elimangalisayo lokunciphisa imithambo yegazi uma kudingeka futhi uyikhulise uma kudingeka.
Into ebalulekile ukuthi lokhu kuncishiswa kwemithambo yegazi ngezinye izikhathi kuyinqubo edingekayo yokuvikela umzimba wethu. Kodwa-ke, ngezinye izikhathi, le nqubo efanayo ingabangela nezinkinga ezinkulu zempilo.
Lokhu kusisiza kanjani? (Izikhathi ezivumayo)
Cabanga ukuthi uye endaweni ebandayo efana neNuwara Eliya. Ngemva kwesikhashana, umzimba wakho uqala ukuthuthumela futhi iminwe yakho ibanda. Okwenzekayo lapha ukuthi ubuchopho bethu buzama ukuvimbela ukushisa komzimba ukuba kuphume kanye nomzimba ukuba ubande (i-Hypothermia). Into eyodwa eyenzayo ukucindezela imithambo yegazi eduze kwesikhumba. Bese, ukugeleza kwegazi esikhumbeni kwehla, kulawula ukulahleka kokushisa okubalulekile ngaphakathi emzimbeni. Lena empeleni yindlela yokuvikela izimpilo zethu.
Futhi, odokotela basebenzisa le mithi ye-vasoconstrictor njengokwelapha izifo ezithile.
- Ukushaqeka: Lawula ukucindezeleka komuntu opha kakhulu, njengangemva kwengozi.
- Ezinye izinhlobo zekhanda elibuhlungu (Ama-Migraine): Lawula ukwanda kwemithambo yegazi ebuchosheni ezinhlungwini ezibuhlungu njenge-migraine.
- Ukuminyana kwamakhala: Eminye imithi yomkhuhlane (imithi yokuqeda ukuminyana kwamakhala) inciphisa imithambo yegazi ekhaleni futhi inciphise ukuminyana.
- I-asthma kanye ne-COPD: Imithi esebenza endleleni yokuphefumula.
Kunini lapho ukuvaleka kwemithambo yegazi kuyingozi khona?
Uma le nqubo yenzeka kakhulu, noma ngesikhathi esingafanele, ingaba yingozi empilweni.
| Umphumela omubi | Incazelo elula |
|---|---|
| Umfutho Wegazi Ophakeme | Uma imithambo yegazi iba mincane, inhliziyo kufanele isebenze kanzima ukuze icindezele igazi kuleyo mithambo yegazi emincane. Uma lokhu kuqhubeka, umfutho wegazi ophakeme uyakhula. |
| Izimo ezifana ne-Phenomenon kaRaynaud | Ukuminyana okukhulu kwemithambo yegazi eholela eminweni nasezinzwaneni kungabangela iminwe ukuba ibe mhlophe, ibe luhlaza okwesibhakabhaka, futhi ibe ndikindiki. |
| Ingozi eyengeziwe yokuhlaselwa yinhliziyo | Uma umuntu onemithambo yenhliziyo ehambisa igazi enhliziyweni ecindezelekile, imithambo yegazi ingancipha futhi ukunikezwa kwegazi enhliziyweni kungaphazamiseka. |
| Umfutho wegazi ophezulu wamaphaphu | Imithambo yegazi emaphashini iyancipha, okwandisa ingcindezi njengoba igazi ligeleza kuyo. Lesi yisimo esibi kakhulu. |
| Ingozi Yokushaywa Yisifo Sokushisa | Kumuntu one-hyperthermia, imithambo yegazi iyancipha, okungenza ukulahlekelwa ukushisa esikhumbeni kube kubi nakakhulu. |
Umfutho Wegazi Ophakeme kanye Nokuvinjelwa Kwemithambo Yegazi
Kukhona ukuxhumana okukhulu phakathi kwalokhu okubili. Uma usuvele unomfutho wegazi ophakeme, izinto ezibangela ukuvaleka kwemithambo yegazi zingaba yingozi kakhulu kuwe kunezinye. Ngoba imithambo yegazi yakho isivele ingaphansi kwengcindezi ethile. Uma incipha kakhulu, ingcindezi yakho ingakhuphuka kakhulu ngengozi.
Yingakho odokotela beluleka abantu abanomfutho wegazi ophezulu ukuthi bangathathi imithi ethile yokuqeda ukuminyana kwemikhuhlane. Le mithi ivimba imithambo yegazi, okungakhuphula umfutho wegazi.
Yiziphi izizathu eziyinhloko zalesi simo?
Ukuvaleka kwemithambo yegazi akuzenzekeli nje. Kunezici eziningana ezikuthintayo.
- Imithi: Imithi enqunywe udokotela, kanye neminye imithi ebandayo engathengwa ekhemisi ngaphandle kwencwadi kadokotela.
- Ezinye izimo zezokwelapha: Izifo ezifana nesifo sikaRaynaud, esikhulume ngaso ngaphambilini.
- Ukucindezeleka: Uma ucindezelekile, umzimba wakho ucabanga ukuthi usengozini. Ama-hormone akhishwa umzimba wakho abangela ukuba imithambo yegazi yakho inciphe.
- Ukubhema: Amakhemikhali akugwayi, ikakhulukazi i-nicotine, anciphisa imithambo yegazi ngokushesha.
- Ukubanda okukhulu: Inqubo yemvelo eyenzeka ukuze kulondolozwe ukushisa komzimba.
- Ukudla neziphuzo ezithile: Ukudla neziphuzo eziqukethe usawoti omningi ne-caffeine. Isibonelo, inyama ecutshunguliwe, ukudla okulula okunosawoti, ikhofi, itiye (ikakhulukazi itiye elinamandla).
Sikulawula futhi sikuvimbele kanjani lokhu?
Into engcono kakhulu ongayenza ukususa imbangela. Isibonelo, uma ubuya emakhazeni uye endaweni efudumele, imithambo yegazi iyavuleka futhi. Kodwa-ke, uma unesifo esifana nesifo sikaRaynaud, kuzodingeka ufune ukwelashwa kudokotela wakho.
Kunezinto eziningana esingazenza ekhaya:
- Lawula ukucindezeleka: Nciphisa ukucindezeleka ngokwenza izinto ezifana nokuzindla, i-yoga, kanye nokuzibandakanya entweni oyithandayo.
- Nciphisa iziphuzo eziqukethe i-caffeine: Nciphisa inani lezinkomishi zekhofi netiye oziphuzayo ngosuku.
- Ukuzivocavoca: Uma uzivocavoca, imithambo yegazi iyavuleka (i-vasodilation) futhi ukugeleza kwegazi kuyathuthuka. Kodwa ungakhohlwa ukufudumala imizuzu embalwa ngaphambi kokuqala ukuzivocavoca.
- Gwema ukubhema ngokuphelele: Lena yinto engcono kakhulu ongayenza.
- Nciphisa ukusetshenziswa kukasawoti: Qaphela inani likasawoti elifakwa ekudleni.
Kufanele simbone nini udokotela?
Ngokuvamile, izinto ezifana nokuba ndikindiki okubangelwa umkhuhlane eminweni yakho azibalulekile. Kodwa-ke, uma unezinye zezimpawu noma izimo ezibalwe ngezansi, kubalulekile ukubona udokotela wakho ngokushesha ukuze uthole iseluleko.
- Umfutho wegazi ophakeme ongalawuleki.
- Uma usola ukuthi une-hypertension yamaphaphu (izimpawu ezifana nokuphelelwa umoya, ubuhlungu besifuba).
- Isimo esiphuthumayo njengokushisa komzimba okuphezulu (i-Hyperthermia).
- Uma iminwe nezinzwane zishintsha umbala njalo, zizwa ubuhlungu noma ukungabi namandla.
Ungazithathi kalula lezi zinto, ngoba ukuthola ukwelashwa okufanele ngesikhathi kungavimbela izinkinga eziningi ezinkulu.
Umlayezo Wokuya Nawe Ekhaya
- I-Vasoconstriction yilapho imisipha ezungeze imithambo yethu yegazi iqina, inciphise ukudlula kwegazi. Lena inqubo evamile eyenzeka emzimbeni wethu.
- Nakuba lokhu kusisiza ngezikhathi ezifana nokusivikela emakhazeni, ukuchayeka ngokweqile kungaholela ezinkingeni ezifana nomfutho wegazi ophakeme kanye nengozi yesifo senhliziyo.
- Ukucindezeleka, ukubhema, kanye nokudla neziphuzo ezine-caffeine/usawoti omningi kungenza lesi simo sibe sibi nakakhulu.
- Uma unomfutho wegazi ophakeme, gwema ukuthatha imithi ethile yomkhuhlane (imithi yokuqeda ukuminyana) ngaphandle kweseluleko sikadokotela.
- Ukulondoloza indlela yokuphila enempilo (ukuzivocavoca umzimba, ukulawula ukucindezeleka) kungalawula kakhulu izimo ezimbi zokuncipha kwemithambo yegazi.
- Uma unokungabaza noma unomuzwa wokuthi izimpawu zakho zimbi kakhulu, qiniseka ukuthi ubona udokotela wakho.
