Yintoni uvavanyo lwe-25-hydroxy vitamin D?

I-Vitamin D inceda umzimba wakho ukuba uthathe i-calcium kwaye ugcine amathambo omelele kubomi bakho bonke. Umzimba wakho uvelisa ivithamin D xa imitha yelanga ye-UV inxibelelana nolusu lwakho. Eminye imithombo elungileyo yevithamini ibandakanya intlanzi, amaqanda, kunye neemveliso zobisi eziqinisiweyo. Ikwafumaneka njengesongezelelo sokutya.

UVitamin D kufuneka ahambe kwiinkqubo ezininzi emzimbeni wakho ngaphambi kokuba umzimba wakho uwasebenzise. Utshintsho lokuqala lwenzeka esibindini. Apha, umzimba wakho uguqula ivithamin D iye kwimichiza eyaziwa ngokuba yi-25-hydroxyvitamin D, ekwabizwa ngokuba yi-calcidiol.

Uvavanyo lwe-25-hydroxy vitamin D yeyona ndlela ilungileyo yokujonga amanqanaba e-vitamin D. Inani le-25-hydroxyvitamin D egazini lakho libonisa kakuhle ukuba ingakanani ivithamin D emzimbeni wakho. Uvavanyo lunokumisela ukuba amanqanaba e-vitamin D aphezulu kakhulu okanye asezantsi kakhulu.

Uvavanyo lukwaziwa njengovavanyo lwe-25-OH ye-vitamin D kunye novavanyo lwe-calcidiol 25-hydroxycholecalcifoerol. Isenokuba sisalathiso esibalulekileyo se-osteoporosis (ubuthathaka bamathambo) kunye neerickets (ukungalunganga kwethambo).

Kutheni le nto kwenziwa uvavanyo lwe-25-hydroxy vitamin D?

Ugqirha wakho unokucela uvavanyo lwe-25-hydroxy vitamin D ngezizathu ezahlukeneyo. Inokubanceda babone ukuba ubuninzi okanye ubuncinci bevithamini D bubangela ubuthathaka bethambo okanye ezinye izinto ezingaqhelekanga. Ikwanokubek 'esweni abantu abasemngciphekweni wokunqongophala kukavithamini D.

Abo basemngciphekweni omkhulu wokuba namanqanaba asezantsi evithamini D abandakanya:

• abantu abangakufumani kakhulu elangeni
• abadala abadala
• abantu abatyebe kakhulu
• Iintsana ezincanciswa kuphela (ifomula ihlala iqiniswe nge-vitamin D)
• abantu abaye benza utyando ngokudlula
• abantu abanesifo esichaphazela amathumbu kwaye senza ukuba kubenzima emzimbeni ukufunxa izakhamzimba, ezifana nesifo sikaCrohn

Ugqirha wakho unokufuna ukuba wenze uvavanyo lwe-25-hydroxy vitamin D ukuba sele befumanise ukuba unesifo se-vitamin D kwaye bafuna ukubona ukuba unyango luyasebenza na.

Uvavanyo lwe-25-hydroxy vitamin D lwenziwa njani?

Ugqirha wakho uza kukuxelela ukuba ungatyi nto iiyure ezine ukuya kwezisibhozo phambi kovavanyo.

Uvavanyo lwe-25-hydroxy vitamin D lufuna uvavanyo lwegazi oluqhelekileyo. Umboneleli wakho wezempilo uza kutsala igazi kumthambo wengalo yakho usebenzisa inaliti. Ukuhlaba ngokukhawuleza komnwe kuya kubonelela ngokwaneleyo kwisampulu yegazi ebantwaneni nakwiintsana.

Ukuvavanya iziphumo zovavanyo lwe-25-hydroxy vitamin D

Iziphumo ziya kuxhomekeka kubudala bakho, isini, kunye neendlela zokuvavanya ezisetyenzisiweyo. Iziphumo zinokwahluka kancinci ukusuka kwelebhu ukuya kwelebhu.

NgokweOfisi yeZongezelelo zeZondlo (i-ODS), amanqanaba evithamini D alinganiswa ngenqanaba le-25-hydroxy kwii-nanomoles / ilitha (nmol / L) okanye ii-nanograms / milliliter (ng / mL). Iziphumo zingabonisa oku kulandelayo:

• ukusilela: ngaphantsi kwe-30 nmol / L (12 ng / mL)
• Ukusilela okunokubakho: phakathi kwe-30 nmol / L (12 ng / mL) kunye ne-50 nmol / L (20 ng / mL)
• Amanqanaba aqhelekileyo: phakathi kwe-50 nmol / L (20 ng / mL) kunye ne-125 nmol / L (50 ng / mL)
• amanqanaba aphezulu: aphezulu kune-125 nmol / L (50 ng / mL)

Ukuba amanqanaba akho e-vitamin D asezantsi kwaye uneempawu zentlungu yethambo, ugqirha unokucebisa ukuskena okhethekileyo ukujonga uxinano lwethambo. Oogqirha basebenzisa le scan ingenabuhlungu ukuvavanya impilo yethambo lomntu.

Amanqanaba egazi asezantsi e-25-hydroxy vitamin D ihlala ithetha enye (okanye nangaphezulu) koku kulandelayo:

• awutyi ukutya okunesondlo, okugqibeleleyo
• amathumbu akho akafunxi ivithamini ngokufanelekileyo
• awuchithi ixesha elaneleyo ngaphandle ukufunxa amanqanaba e-vitamin D ngokwaneleyo ngokuvezwa lilanga

Obunye ubungqina budibanisa ukunqongophala kukavithamini D kumngcipheko ophezulu womhlaza othile, izifo zomzimba, kunye nesifo sentliziyo.

Amanqanaba aphezulu evithamini D egazi ngokubanzi abangelwa kukuthatha iipilisi ezininzi zevithamini kunye nezinye izongezo zesondlo. Amanani aphezulu evithamini D angakhokelela kwimeko ebizwa ngokuba yi-hypervitaminosis D. IHypervitaminosis yinto enqabileyo kodwa enzima enokukubeka emngciphekweni wesibindi okanye iingxaki zezintso.

Amanqanaba aphezulu kunqabile ngenxa yokutya iivithamini kakhulu ngokutya okanye ngokuvezwa lilanga.

Ugqirha wakho uya kukunceda ucacise iziphumo zovavanyo lwakho kwaye unqume ukuba ngaba une-vitamin D.

Umngcipheko wovavanyo lwe-25-hydroxy vitamin D

Njengalo naluphi na uvavanyo lwegazi oluqhelekileyo, umngcipheko wovavanyo lweevithamini ezingama-25 zincinci kwaye zibandakanya:

• ukopha kakhulu
• intloko elula
• ithuba elincinci losulelo apho inaliti igqobhoza ulusu lwakho

Imbonakalo

Vitamin D ibalulekile emzimbeni. Ukusilela nakweyiphi na iminyaka kungadala iingxaki. Ugqirha wakho unokuncomela izongezo okanye ezinye iindlela zonyango ukuba awunanto. Ukutya ukutya okuqulathe ivithamin D ukongeza ukongeza kwizongezo kwirejimeni yakho kunokunceda ukugcina amanqanaba e-vitamin D azinzile.
