Ukuhlolwa kukavithamini D: kwenzelwa ini, kwenziwa kanjani nemiphumela

• Ukuthi imiphumela isho ukuthini
• Ukwehla kwamavithamini D amanani
• Amanani akhuphukile kavithamini D

Ukuhlolwa kukavithamini D, okwaziwa nangokuthi yi-hydroxyvitamin D noma ukuhlolwa kwe-25 (OH) D, kuhlose ukuhlola ukuminyana kukavithamini D egazini, njengoba kuyi-vitamin ebalulekile ekulawuleni amazinga e-phosphorus ne-calcium, aneqhaza elibalulekile ku-bone metabolism, isibonelo.

Lokhu kuhlolwa kuvame ukucelwa ngudokotela ukuthi aqaphe ukwelashwa okufaka esikhundleni se-vitamin D noma lapho kunezibonakaliso nezimpawu ezihlobene nokuqaqanjelwa kwamathambo, njengobuhlungu nobuthakathaka bemisipha, ngokwesibonelo, ukucelwa kakhulu kanye nomthamo we-calcium, PTH kanye i-phosphorus egazini.

Ukuthi imiphumela isho ukuthini

Kusukela emiphumeleni yomthamo we-25-hydroxyvitamin D kungenzeka ukuthi kuboniswe ukuthi ngabe umuntu unenani elanele likavithamini D elijikeleza egazini ukugcina impilo yethambo. Ngokwesincomo sango-2017 seBrazil Society of Clinical Pathology / Laboratory Medicine kanye neBrazil Society of Endocrinology and Metabology ^[1], amazinga anele kavithamini D yilawa:

• Kubantu abaphilile:> 20 ng / ml;
• Kubantu beqembu eliyingozi: phakathi kuka-30 no-60 ng / mL.

Ngaphezu kwalokho, kunqunywa ukuthi kunengozi yobuthi kanye ne-hypercalcemia lapho amazinga kavithamini D engaphezulu kwe-100 ng / mL. Mayelana namazinga athathwa njenganganele noma entula, kwenziwa izifundo ngale nhloso, kepha kunconywa ukuthi abantu abethula amanani angaphansi kwalokhu kunconyiwe bahambisane nodokotela futhi, ngokwezinga elikhonjiwe, ukwelashwa okufanele kakhulu kuyaqalwa .

Ukwehla kwamavithamini D amanani

Ukwehla kwamanani kavithamini D kukhombisa i-hypovitaminosis, okungenzeka ukuthi kungenxa yokuchayeka okuncane elangeni noma ukudla okuncane kokudla okunothe ku-vitamin D noma okwandulelayo, njengeqanda, inhlanzi, ushizi namakhowe, ngokwesibonelo. Thola okunye ukudla okunothe ku-vitamin D.

Ngaphezu kwalokho, izifo ezinjengesibindi esinamafutha, ukuqina kwesibindi, ukungasebenzi kahle kwepancreatic, isifo sokuvuvukala, ama-rickets kanye ne-osteomalacia kanye nezifo eziholela ekuvukeleni emathunjini kungaholela ekushodeni noma ekushodeni kukavithamini D.

Amanani akhuphukile kavithamini D

Amanani akhuphukile kavithamini D akhombisa ukuthi i-hypervitaminosis, eyenzeka ngenxa yokusebenzisa uvithamini D omningi isikhathi eside. Ukutholakala elangeni isikhathi eside akuholeli ku-hypervitaminosis, njengoba umzimba ukwazi ukulawula inani likavithamini D futhi lapho kutholakala ukugxila okuphelele, kukhonjiswa ukuthi ukuhlanganiswa kukavithamini D ngokuvuselelwa yilanga kuyaphazamiseka ngakho-ke , awekho amazinga anobuthi kavithamini D ngenxa yokuchayeka isikhathi eside elangeni.
