I-Potassium ikhono lokunciphisa uxinzelelo lwegazi luvame ukunyanzelwa
Uxinzelelo lwexinzelelo, (okanye ukunyuswa kwengcinezelo yegazi engavumelekanga) yenye yezona zifo eziqhelekileyo eziqhelekileyo. Ngoko ke yinkinga yempilo yoluntu. Njengamaziko okuLawula izifo (CDC), ukukhula koxinzelelo lwengqondo phakathi kwabantu abadala base-US abaneminyaka engama-18 nangaphezulu kwaphakama njengama-29.1 ekhulwini ngo-2011-2012. Ehlabathini lonke, ukuxhaphaka kwegazi ngokuphakanyiswa kwabantu abadala abaneminyaka engama-25 nangaphezulu kunama-40 ekhulwini ngo-2008.
Uxinzelelo oluphezulu lwegazi luba nemiphumo emibi, ekhokelela ekungciphekweni kwengozi, ukuhlasela kwentliziyo, ukungaphumeleli kwezintso, njl. Ukonyangwa kwengcinezelo yegazi yintsimi eqhubekayo, into eyenziwa malunga nekhulu leminyaka edlulileyo.
Imbali emfutshane ye-Hypertension
Kunzima ukucinga ukuba isicwangciso samhlanje sokulinganisa uxinzelelo lwegazi sele sasijikeleze iminyaka engaphezu kwe-100 (xa uDkt. Kortokoff, udokotela ogqirha waseRashiya, echaza indlela kwimihlathi enye). Ngoxa sasingakwazi ukulinganisa uxinzelelo lwegazi, akukho mntu wayesazi ngokwenene ukuba isisigxina soxinzelelo segazi esifanelekileyo. Kamva, uphando olwenziwe ngabantu luqhutyelwe ukuphendula lo mbuzo. Ngaloo nto kwafika ukuqonda ukuba ukunyuswa kwengcinezelo yegazi kunokunyusa umngcipheko weentliziyo kunye nesifo se-vascular.
Ngelishwa, ngasekuqaleni kwekhulu lama-20, akukho unyango olungileyo okhoyo kwi-hypertension. Naliphi na isicwangciso sonyango esincinci sasiyinkqantosi esingaqhelekanga kunye neyentaba ngemilinganiselo yanamhlanje.
Ezi ziquka ukuthunyelwa kwegazi nge-phlebotomy, okanye ukusika iintso zomntu ukuhambisa uxinzelelo lwegazi. Enyanisweni, uxinzelelo oluphezulu lwegazi lwaluthi lubhekiselele njengengcinezelo engathandabuzekiyo, igama elibi libonisa ukugxekwa njengento embi njengomhlaza.
Ionyango zanamhlanje kwi-High Blood Pressure
Namhlanje, oogqirha abasasafunekanga ukudlala i-vampire ukunyanga izigulane zegazi eziphezulu.
Oku kuyingxenye ngenxa yokuqonda kwethu okuphuculweyo kwimizimba yexinzelelo lwegazi kunye nefuthe lezinto zangaphandle ezifana nokutya (okuquka i-electrolytes njenge-sodium, i-potassium, njl njl.). Njengeengxaki ezininzi nangona kunjalo, xa sifunda ngakumbi, imibuzo eninzi iyakhula.
Ngoko, umntu oqhelekileyo angenza impazamo yokucinga ukuba ugqirha wanamhlanje uphumelele ubugcisa kunye nesayensi yokuphatha uxinzelelo lwegazi oluphezulu. Nangona kunjalo, nanamhlanje, unyango lwexinzelelo lwengqondo kunye nendlela yokusingatha le ngxaki kusengumcimbi wophando olunzulu kunye neengxoxo. Omnye ufuna kuphela ukubheka izikhokelo ezininzi ezipapashwe yimibutho ehlabathini lonke etshela ugqirha oqhelekileyo ngexesha kunye nendlela yokuphatha unyango ophezulu lwegazi. Amabango ngamagama amabini okugqibela kwisifundo; okokuba, kufike isikhokelo esilandelayo. Esinye sezikhokelo eziqhelekileyo ezisetyenziswa e-US ngamagqirha ekuphatheni umfutho wexinzelelo yinto ebizwa ngokuba yi-Joint National Committee (JNC) izikhokelo.
I-Blood Pressure ilawulwa njani?
Ngaphambi kokuba siqonde indima ye-potassium ekulawuleni uxinzelelo lwegazi, kubalulekile ukuba ube nombono ocacileyo ngokuthe ngqo ukuba "i-thermostat" yomzimba wayo isebenza njani. Le ntsimbi iquka ukulungelelaniswa kwezixhobo ezilawulwa yinkqubo yesifo, izintso, inkqubo ye-endocrine eyenza i-hormone, intliziyo, imithwalo yegazi, ubungakanani bemithombo yamanzi, i-electrolyte yamanqanaba kunye nokunye.
Kukho into ebonakala ingento encinci (njengokuba uthethi, "uxinzelelo lwangegazi luhamba nge-120/80"), kuyamangalisa ukuqonda indlela le ndlela eyinkqubo eyinkqubo efunekayo ukuba isebenze ngokulungelelanisa ngokugqibeleleyo yonke yesibini yobomi bethu ukuze sigcine igazi lethu uxinzelelo olusebenzayo kuphela apho kufuneka lube khona.
I-Electrolytes kunye ne-Hypertension: I-Potassium
Xa kuziwa kwi-electrolytes kunye noxinzelelo lwegazi, amaninzi amagqirha kunye nomntu oqhelekileyo uyaziqonda indima ye-sodium. Izigulane zibethelwa ngemilayezo malunga nokusika i-sodium intake, kwaye ngokunjalo. Ngelishwa, ukugxininiswa okwaneleyo kunikwa ngexesha leengxoxo zeklinikhi malunga nendima enenzuzo ye potassium kwixinzelelo legazi.
Njengoko kuchazwe apha , i-potassium ineyona indima ebalulekileyo kwi-physiology yabantu, kwaye yinto ebalulekileyo ebomini. Amanqanaba ayo agcinwa kakhulu yizintso. Kukho idatha ebonisa ukuba ukungadli i-potassium eyaneleyo ekudleni kwethu kunokukhokelela kunyuka kwimixinzelelo yegazi, kwaye kwandisa ingozi yesifo sesifo kunye nesifo. Kukho neenkcukacha ezivela kwi-meta-analysis ebonisa ukuba ukunyuswa kwegramu ye-1.6 kwi-potassium intlawulo ngosuku kungenza umngcipheko we-stroke ungaphantsi kwama-21 ekhulwini. Yaye ukuba unyongela imeko ngokutya umlinganiselo ophezulu we-sodium kunye, ke ukuchaphazela kwixinzelelo legazi kukhankanya ngakumbi. Ngoko ke kubonakala ngathi xa kuziwa kwixinzelelo lwegazi, i-potassium ngokucacileyo yindoda enhle.
Kutheni i-Potassium ephantsi kweengcinezelo zegazi?
Asiqinisekanga okwamanje. Nangona kunjalo, oku kwakhona ngumxholo wophando osebenzayo. Enye yeengcamango ezifundwayo yifuthe le-potassium kwiintso 'ukukwazi ukulahla i-sodium emzimbeni. Siyazi ukuba iqondo eliphantsi legazi le potassium ukusuka kwisitya esincinci se-potassium sinokunyusa ukubuyiswa kwakhona kwe-sodium kwiintso, kwaye kubangele ingozi ephezulu yengozi.
Ngaba unokutya isidlo sePotassium ephezulu?
Nangona iilingo ezininzi zaqhutyelwa ukuphendula lo mbuzo, ukuhlaziywa kwe-meta-mkhulu yeemvavanyo ezili-16 zenze ukuba kube lula ukutolika idatha ngokucoca iinombolo kuthi. Ngoko ke sinobungqina bokuba ukunyuka kwindleko ye-potassium kunokunciphisa uxinzelelo lwegazi kwizigulane ezithwaxwa yingxinzelelo. Nangona kunjalo, abantu abaqhelekileyo abanengxaki yexinzelelo yegazi abanakho ukubona ukunciphisa okufanayo. Kukho kubonakala kubakho ukulungelelanisa phakathi kwesantya kunye nesiphumo, apho abantu abanokunyuka okuphezulu kwi-potassium intake (ye-90-120 mEq ngosuku) banokubona ukuncitshiswa okukhulu kwegazi.
Ukutya okuphezulu kwePotassium akuyena wonke umntu
Ngaphambi kokuba uqale ukugcoba amabhanana kunye netamatato, nceda uthathe imizuzu embalwa ukuxoxa nodokotela wakho nokuba ungadli ngokutya okuphezulu. Kuza kubakho abantu abanokutya okuphakamileyo kwe-potassium abangalimaza kunokuba kunceda. Ezi ziquka abantu abanesifo esiphambili sezintso, okanye abantu kwiindidi ezithile zengcinezelo yegazi njengoko i-angiotensin iguqulela i-enzyme (ACE) inhibitors okanye i-spironolactone, apho ukutya okuphezulu kweso potassium kunokwandisa umngcipheko wezinga eliphezulu legazi le-potassium / hyperkalemia. Ukuba isigulane esifanelekileyo, kodwa isondlo esinobutyebi esinokutya singase sibe neenzuzo zenhliziyo, njengoko idatha ingentla ibonisa.
