Uxinzelelo lwegazi luchaza amandla asetyenziswa ligazi kwiindonga zemithambo, imithambo kunye neecapillaries. Kwimeko yoxinzelelo lwegazi oluphezulu, uxinzelelo kwiindonga zeenqanawa lukhulu kakhulu, ngoko ke kwimeko embi kakhulu, kunokukhokelela kwiindidi ezininzi zokulimala kwamalungu kunye ne-nerve. Iikati nazo zinokuchaphazeleka.
Uxinzelelo lwegazi oluphezulu lulinganiswa njani kwiikati?
Ukuze ulinganise ngokuchanekileyo uxinzelelo lwegazi kwaye ukhangele ukuba uphezulu kakhulu, udinga isixhobo esikhethekileyo sokulinganisa. Ngaphambili, into ebizwa ngokuba yi-mercury manometers yayisetyenziselwa ukulinganisa uxinzelelo lwegazi kubantu, yingakho iyunithi ye-millimeters ye-mercury (mmHg) isaxhaphakile namhlanje - kubantu nakwizilwanyana.
Ixabiso eliphezulu le-120 ukuya kwi-140 mmHg libhekwa njengesiqhelo kwiikati, ukusuka kwi-150 uxinzelelo lwegazi luphakanyiswe kancane kwaye lusuka kwi-160 luphakanyiswe ngokulinganayo. Ngaphezulu kwexabiso le-180, umngcipheko wokulimala kwamalungu ukusuka kwixinzelelo legazi eliphezulu kakhulu.
Iimpawu ezinokwenzeka zoxinzelelo lwegazi oluphezulu
Iimpawu zoxinzelelo lwegazi zicuthe kakhulu okanye azicacanga. Iimpawu ezinokuthi zilumkise ziquka ukopha kwiliso kunye nokuphuma kwe-retina, okunokubangela ukuba ikati ibe yimfama. Iingxaki zokuziphatha ezinje ngokugqithisileyo, ukungakhathali, okanye ukuxhuzula zisenokwenzeka ngoxinzelelo lwegazi oluphezulu. Ukuba ikati yakho inesifo seswekile, ikhuluphele, ine-thyroid gland (hyperthyroidism), okanye inesifo esinganyangekiyo sezintso, kufuneka uhlolisise uxinzelelo lwegazi lwekati yakho rhoqo. Ezi zifo zinokubangela uxinzelelo lwegazi oluphezulu. Isifo seswekile, iingxaki zezintso, nedlala lengqula elisebenza ngokugqithiseleyo nalo lunokwenziwa mandundu luxinezeleko oluphezulu lwegazi, nto leyo edala umjikelo ombi.
Ngoko ke, kungcono ukuya kugqirha wezilwanyana ukuba ukrokrela ukuba ikati yakho inokuba inoxinzelelo lwegazi oluphezulu. Ukuba ngokwenene ufumanise ukuba uxinzelelo lwegazi lwakho luphezulu kakhulu, kunokuba luncedo ukuzithengela isixhobo sokulinganisa ukuze ukwazi ukujonga impilo yekati yakho rhoqo ekhaya. Iigeyiji ziza necuff oyisonge emsileni wekati okanye umlenze wangaphambili. Ungakhathazeki: ayizukulimaza impumlo yakho yoboya.
Kutheni uxinzelelo lwegazi oluphezulu luyingozi
Uxinzelelo lwegazi olugqithileyo alunakukhokelela nje kubumfama kwiikati kodwa lunokwenza mandundu kumalungu akhoyo kunye neengxaki zemetabolism. Uxinzelelo lwegazi oluphezulu lukwanyusa umngcipheko weengxaki zentliziyo okanye ukubetha kwentliziyo kwiikati. Kungcono ke ngoko ukuba uxinzelelo lwakho lwegazi lulinganiswe rhoqo kunokuba ungalulinganisi kwaphela ukuze wena nogqirha wakho wezilwanyana niqalise unyango lwe-antihypertensive kwangethuba.
