Ucwaningo luye lwabonisa ukuthi ukubhema kunomthelela omkhulu kumfutho wegazi. Ukubhema kungabangela umfutho wegazi ophakeme. Ngemva kokubhema ugwayi, izinga lokushaya kwenhliziyo likhuphuka izikhathi ezingu-5 kuya kwezingu-20 ngomzuzu, kanti umfutho wegazi we-systolic ukhuphuka ngo-10 kuya ku-25 mmHg.
Ezigulini ezingalashwa ezinomfutho wegazi ophakeme, i-systolic yamahora angu-24 kanye ne-diastolic blood pressure yababhemayo iphakeme kunaleyo yabangabhemi, ikakhulukazi umfutho wegazi wasebusuku uphakeme kakhulu kunalabo abangabhemi, futhi ukukhuphuka komfutho wegazi ebusuku kuhlobene ngokuqondile ne-hypertrophy ye-left ventricular, okusho ukuthi, ukubhema kuzobangela ukwanda kwengcindezi yegazi kanye nenhliziyo.
Ngoba ugwayi netiye kuqukethe i-nicotine, eyaziwa nangokuthi i-nicotine, engavusa inzwa emaphakathi nenzwa enozwela ukuze kusheshiswe ukushaya kwenhliziyo. Ngesikhathi esifanayo, iphinde ikhuthaze indlala ye-adrenal ukuthi ikhulule inani elikhulu lama-catecholamines, okwenza inkontileka ye-arterioles, okuholela ekwandeni komfutho wegazi. I-Nicotine ingabuye ivuse ama-chemical receptors emithanjeni yegazi futhi ibangele ukwanda komfutho wegazi.
Uma abantu abanomfutho wegazi ophakeme beqhubeka nokubhema, kuzokwenza umonakalo omkhulu. Ngenxa yokuthi ukubhema kungabangela ngokuqondile ukulimala kwemithambo yegazi, lokhu kuye kwaqinisekiswa ngokucacile ezifundweni zomtholampilo. Ukubhema kuzodala i-arterial intima ngenxa ye-nicotine, i-tar nezinye izingxenye eziyingozi kugwayi, okungukuthi, kuzoba nomonakalo ku-intima ye-arterial. Ngokulimala kwe-intima ye-arterial, i-atherosclerotic plaque izokwakhiwa. Ngemuva kokwakhiwa okuqhubekayo kwezilonda ezihlakazekile, kuzothinta ukufinyela nokuphumula kwemithambo yegazi evamile. Uma isiguli sinomfutho wegazi ophakeme futhi sinomkhuba wokubhema, kuzosheshisa ukuqhubeka kwe-atherosclerosis.
Ukubhema kanye nomfutho wegazi ophakeme kokubili kuyizici ezibalulekile eziyingozi ezifweni zenhliziyo nemithambo yegazi. Lapho i-atherosclerotic plaque iqhubeka, i-vascular stenosis izoba sobala kakhulu, okuholela ekungangeni kwegazi okwanele ezithweni ezihambisanayo. Umonakalo omkhulu i-atherosclerotic plaque, engase iholele ekuweni koqweqwe olungazinzile, okuholela ezenzakalweni ezinzima ze-thrombotic, njenge-cerebral infarction kanye ne-myocardial infarction. Ukubhema kuzoba nomthelela ku-hypertension, ngoba kuzothinta ukukhululeka nokufinyela kwemithambo yegazi, kube nzima ukulawula umfutho wegazi, ngisho nokwenyuka okubukhali komfutho wegazi. Ngakho-ke, kuphakanyiswa ukuthi iziguli ezinomfutho wegazi ophakeme kanye nokubhema kufanele zizame ukuyeka ukubhema.
I-World Health Organisation inqume ukuqoka uMeyi 31 njalo ngonyaka njengoSuku Lomhlaba Lokungabheki Kagwayi, kanti iChina nayo ithatha lolu suku njengosuku lwaseChina olungabheki. Lolu suku lokungabhemi luhlose ukukhumbuza umhlaba ukuthi ukubhema kuyingozi empilweni, kunxuse ababhemayo emhlabeni wonke ukuthi bayeke ukubhema, futhi kunxuse bonke abakhiqizi bakagwayi, abadayisi kanye nawo wonke umphakathi wamazwe omhlaba ukuba uhlanganyele emkhankasweni wokulwa nokubhema ukuze kwakheke isintu indawo engenagwayi.
Okwamanje, kufanele sinake kakhulu ukuqapha umfutho wegazi ekuphileni kwethu kwansuku zonke. Manje imishini eminingi yezokwelapha yasendlini enomklamo olula nokusetshenziswa kalula ingena kancane kancane ezinkulungwaneni zemizi. Umshini wokuqapha umfutho wegazi wedijithali wasendlini uzoba yinketho engcono kuwe yokunakekela impilo yakho.
