Vitamin D bvunzo: ndeyei, maitirwo ayo uye mhedzisiro
Zvemukati
Iyo vhitamini D bvunzo, inozivikanwawo sehydroxyvitamin D kana 25 (OH) D bvunzo, inovavarira kutarisa kuwanda kwevhitamini D muropa, sezvo iri vhitamini yakakosha mukugadzirisa kweropa phosphorus uye calcium mazinga, iine basa rakakosha mune bone bone metabolism, semuenzaniso.
Muedzo uyu unowanzo kumbirwa nachiremba kuti atore marapirwo ekutsiva aine vhitamini D kana paine zviratidzo nezviratidzo zvine chekuita nekudzikiswa kwepfupa, sekurwadziwa uye kushaya simba kwemhasuru, semuenzaniso, uchiwanzokumbirwa pamwe chete neiyo muyero we calcium, PTH phosphorus muropa.
Zvinoreva mhedzisiro
Kubva pamhedzisiro yeiyo 25-hydroxyvitamin D muyero zvinokwanisika kuratidza kuti munhu wacho ane huwandu hwakakwana hwevitamin D inotenderera muropa kuchengetedza hutano hwemabhonzo. Zvinoenderana neye 2017 kurudziro yeBrazilian Society yeClinical Pathology / Laboratory Medicine uye yeBrazil Society yeEndocrinology neMetabology [1], akakwana mazinga evitamini D ndeaya:
- Kune vanhu vane hutano:> 20 ng / mL;
- Kune vanhu veboka rine njodzi: pakati pe30 uye 60 ng / mL.
Uye zvakare, zvakatemwa kuti kune njodzi yekutapukisa uye hypercalcemia apo mavitamini D mazinga ari pamusoro pe100 ng / mL. Panyaya yematanho anoonekwa seasina kukwana kana kushomeka, zvidzidzo zviri kuitwa nechinangwa ichi, zvisinei zvinokurudzirwa kuti vanhu vanopa tsika pazasi pezvakakurudzirwa vanoperekedzwa nachiremba uye, zvinoenderana nedanho rakatarwa, kurapwa kwakanyanya kwakatangwa .
Yakadzikira mavitamini D kukosha
Izvo zvakadzikira kukosha kwevhitamini D zvinoratidza hypovitaminosis, izvo zvinogona kunge zvichikonzerwa nekushomeka kwezuva kana kudya zvishoma zvekudya zvakapfuma muvhitamini D kana zvisati zvaitika, senge zai, hove, chizi uye howa, semuenzaniso. Tsvaga zvimwe zvekudya zvakapfuma muvhitamini D.
Pamusoro pezvo, zvirwere zvakaita seakakora chiropa, cirrhosis, kurwara kwepancreatic, chirwere chinoputika, rickets uye osteomalacia uye zvirwere zvinotungamira kuzvimba mumatumbu zvinogona kukonzera kushomeka kwevhitamini D kana kushomeka. Ziva maitiro ekuziva zviratidzo zvekushomeka kwevhitamini D.
Kuwedzera kukosha kwevhitamini D
Iko kuwedzera kwehunhu hwevhitamini D zvinoratidza hypervitaminosis, inoitika nekuda kwekushandiswa kwehuwandu hwevhitamini D kwenguva yakareba. Kugara kwezuva kwenguva refu hakukonzere hypervitaminosis, sezvo muviri uchikwanisa kudzora huwandu hwevhitamini D uye kana kuwonekwa kwakaringana kuchionekwa, zvinoratidzwa kuti synthesis yevhitamini D nekusimudzira kwezuva yakakanganiswa uye, nekudaro , hapana huturu hwakanyanya. vhitamini D nekuda kwekugara kwezuva kwenguva refu.
