Uvavanyo lwe-25-hydroxy vitamin D

Uvavanyo lwe-25-hydroxy vitamin D yeyona ndlela ichanekileyo yokulinganisa ukuba ingakanani ivithamin D esemzimbeni wakho.

I-Vitamin D inceda ukulawula amanqanaba e-calcium kunye ne-phosphate emzimbeni.

Isampulu yegazi iyafuneka.

Ngokwesiqhelo, awuyi kuzila ukutya. Kodwa oku kuxhomekeke kwilabhoratri kunye nendlela yovavanyo esetyenzisiweyo. Landela nayiphi na imiyalelo yokungatyi ngaphambi kovavanyo.

Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukuthotywa okuthile.

Olu vavanyo lwenziwa ukumisela ukuba unovithamin D omninzi okanye omncinci kakhulu egazini lakho. Ukuvavanywa kwabo bonke abantu abadala, nokuba ukhulelwe, kumanqanaba asezantsi e-vitamin D akacetyiswa.

Nangona kunjalo, ukuhlolwa kungenziwa kubantu abasengozini enkulu yokunqongophala kwe-vitamin D, njengale:

• Ngaphezulu kweminyaka yobudala engama-65 (zombini ukuveliswa kolusu lwe-vitamin D kunye nokufunxwa kwesisu ku-vitamin D kuyehla njengoko sikhula)
• Ngaba batyebile (okanye baphulukene nobunzima kutyando lwe-bariatric)
• Bathatha amayeza athile, anjenge phenytoin
• Unamathambo okanye amathambo abhityileyo
• Ukukhanya kwelanga
• Unengxaki yokufumana iivithamini kunye nezakha-mzimba emathunjini abo, ezinje nge-ulcerative colitis, isifo se-Crohn, okanye isifo se-celiac

Uluhlu oluqhelekileyo lwevithamini D lilinganiswa njengee-nanograms nge-milliliter nganye (ng / mL). Iingcali ezininzi zincoma inqanaba eliphakathi kwama-20 no-40 ng / mL. Abanye bacebisa inqanaba eliphakathi kwama-30 nama-50 ng / mL.

Imizekelo engentla yimilinganiselo eqhelekileyo yeziphumo zolu vavanyo. Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Ezinye iilebhu zisebenzisa imilinganiselo eyahlukeneyo okanye ukuvavanya iisampulu ezahlukeneyo. Thetha nogqirha wakho malunga nentsingiselo yeziphumo zakho zovavanyo, nokuba ngaba unokufuna na izongezo zevithamin D.

• 25 i-hydroxy vitamin D3 (cholecalciferol) ngu-vitamin D owenziwe ngumzimba wakho okanye owufunxileyo kwimvelaphi yezilwanyana (ezinjengeentlanzi ezinamafutha okanye isibindi) okanye isongezelelo secholecalciferol.
• 25 i-hydroxy vitamin D2 (ergocalciferol) yivithamin D oyifunxileyo kukutya okuqiniswe yivithamin D yesityalo okanye isongezo se-ergocalciferol.
• Iihomoni ezimbini (i-ergo- kunye necholecalciferol) zisebenza ngokufanayo emzimbeni. Ixabiso elibalulekileyo lilonke inani lama-25 le-hydroxy vitamin D egazini lakho.

Inqanaba elisezantsi kuneliqhelekileyo linokubangelwa kukunqongophala kwe-vitamin D, enokubangela:

• Ukungabikho kolusu elangeni, ulusu olunombala omnyama, okanye ukusetyenziswa okungagungqiyo kwescreen selanga esikwi-SPF
• Ukungabikho kwe-vitamin D eyaneleyo ekudleni
• Izifo zesibindi nezintso
• Ukufakwa kukutya okungalunganga
• Ukusetyenziswa kwamayeza athile, kubandakanya i-phenytoin, i-phenobarbital, kunye ne-rifampin
• Ukufakwa kakubi kwe-vitamin D ngenxa yokuguga, ukuhlinzwa okwehlisa ubunzima, okanye iimeko apho amanqatha engafakwanga kakuhle

Inqanaba eliphantsi le-vitamin D liqhelekile kubantwana base-Afrika baseMelika (ngakumbi ebusika), nakwiintsana ezincanciswa kuphela.

Inqanaba eliphezulu kuneliqhelekileyo linokubangelwa kukungabikho kwe-vitamin D, imeko ekuthiwa yi-hypervitaminosis D. Oku kubangelwa kakhulu kukuthatha ivithamin D. Kunokubangela ukuba kubekho ikhalsiyam eninzi emzimbeni (hypercalcemia). Oku kukhokelela kwiimpawu ezininzi kunye nomonakalo wezintso.

Akukho mngcipheko ubandakanyekileyo ekuthatheni igazi lakho. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka komnye umntu ukuya komnye nakwelinye icala lomzimba liye kwelinye. Ukuthatha igazi kwabanye abantu kunokuba nzima ngakumbi kunabanye.

Eminye imingcipheko enxulumene nokutsalwa kwegazi incinci, kodwa inokubandakanya:

• Ukopha kakhulu
• Ukugqobhoza okuninzi ukufumana imithambo
• Ukufa isiqaqa okanye ukuziva ungenantloko
• I-Hematoma (igazi eliqokelela phantsi kwesikhumba)
• Usulelo (umngcipheko omncinci nangaliphi na ixesha ulusu lwaphukile)
