Izifundo zaboniswa kwi-European Endocrinology Congress eLondon ebonisa ukuba i-vitamin D ibaluleke kakhulu ekuzaleni, kokubili amadoda kunye nabasetyhini. Inyaniso yokuba ivithamin D inokunyusa amanqanaba e testosterone kumadoda awayekade enengxaki yokunqongophala kwevithamin D yayisele yaziwa. Uphononongo olutsha ngoku lutyhile ngakumbi amakhonkco phakathi kwevithamin D kunye nokuchuma komntu. Kwimeko yeengxaki zokuzala, inqanaba levithamini D kufuneka lihlale liqwalaselwa.
I-Vitamin D ikhuthaza ukuchuma
I-Vitamin D yi-hormone eveliswa eluswini phantsi kweempembelelo zokukhanya kwelanga. Kuphela kukutya okumbalwa okunezixa ezifanelekileyo zevithamin D ngoko ke uninzi lwevithamin D efunekayo kufuneka iveliswe ngumzimba ngokwawo. Impembelelo ye-vitamin D kwi-metabolism yamathambo iyaziwa ngokukodwa. Unyango lwe-Osteoporosis ke ludla ngokubandakanya ukulungiswa kwe-vitamin D ngokudityaniswa ne-calcium.
Okwangoku, nangona kunjalo, siyazi ukuba i-vitamin D inemiphumo eyahlukileyo ngokupheleleyo. Imiselwe isifo seswekile, umhlaza, kunye nezifo zentliziyo ngenxa yeziphumo zayo ezichasayo kunye nokulawula. Ivithamin iphinda ilawule amajoni omzimba, ithomalalisa iintlungu, kwaye - njengoko sisazi ngoku - inefuthe lokuphucula ukuchuma.
I-Vitamin D inyusa amanqanaba e-testosterone
Ukuya kutsho kuma-80 ekhulwini kubemi baseYurophu kuthiwa banengxaki yokunqongophala kwevithamin D. Abantu abakhetha ukuhlala phantsi kunye nendlela yokuphila engafanelekanga bachaphazeleka ngakumbi. Kwiimeko ezininzi, batyebe kakhulu ngaxeshanye. Okukhona ukutyeba kakhulu, kokukhona lisezantsi inqanaba levithamin D. Kwimeko yokunqongophala kwe-vitamin D, ukulawula ubunzima kufuneka kuhlale kuqwalaselwa.
Ukuba indoda ine-vitamin D enqongopheleyo ngexesha elifanayo nenqanaba le-testosterone ephantsi, ngoko i-vitamin D izongezelelo ezinokunyusa izinga le-testosterone kwaye ngaloo ndlela iphucule ukuchuma kwendoda. Kwaye kwafunyaniswa ukuba inqanaba le-testosterone lihambelana ngqo nenqanaba le-vitamin D, oku kuthetha ukuba inqanaba le-vitamin D liphezulu, liphezulu izinga le-testosterone. Sinike ingxelo malunga nolu nxibelelwano apha: I-Vitamin D inyusa amanqanaba e-testosterone
I-Vitamin D kunye nefuthe layo ekuchumeni
Kwiminyaka yakutshanje, ukuzala kwabasetyhini kwehle kakhulu, kwaye umgangatho wamadlozi wamadoda nawo uye wehla ngokuthe ngcembe. Izizathu zale nto ibingafane ibonwe. I-10 ukuya kwi-15 ipesenti yazo zonke izibini ezitshatileyo ezifuna ukuba nabantwana zingenabantwana - kwaye ukuya kuthi ga kwi-10 ekhulwini labo bonke abafazi abaneminyaka yobudala yokuzala bahlupheke kwi-polycystic ovarian syndrome (PCOS), ingxaki ye-hormone engapheliyo enokuthi idibaniswe nokungabikho komntwana.
Ugqirha Elisabeth Lerchbaum osuka kwiYunivesithi yezoNyango yaseGraz sele eqhube izifundo ezininzi ukufumanisa isiphumo sevithamin D kwimiba eyahlukeneyo yokuchuma kwamadoda nabasetyhini. Ufumanise ukuba ivithamin D inokuba nefuthe elihle kakhulu ekuchumeni kuzo zombini izini:
- Kumadoda, umzekelo, akugcini nje ukwandisa amanqanaba e testosterone, kodwa kunye nokuveliswa kunye nokuvuthwa kwesidoda.
- Kwabasetyhini, i-vitamin ilawula umjikelezo wokuya esikhathini kwaye ikhuthaza ukuvuthwa kweeseli zeqanda kunye nokuphuhliswa kwentambo yesibeleko ukuze i-embryo ikwazi ukuzinza.
- Ukuveliswa kweehomoni zesondo - kumadoda nabasetyhini - nako kongezwa yivithamin yelanga.
- Nge-in vitro fertilization (IVF), impumelelo iyanda xa inqanaba levithamini D liphezulu ngokwaneleyo, ngoko izibini ezifuna ukuzalisekisa umnqweno wazo wokuba nabantwana ngale ndlela zifanele zihlale zibeke iliso kumanqanaba azo evithamini D.
- Nge-PCOS kunye ne-endometriosis (enye into enokunciphisa ukuchuma) sele kukho iziphumo ezilungileyo malunga ne-vitamin D.
Unyango lokunyusa ukuchuma: IVithamin D yinxalenye ebalulekileyo
Ngokuqinisekileyo, uphando olongezelelweyo oluphezulu oluphezulu lwe-randomized kunye nokulawulwayo luyafuneka ukuze kufumaneke ukuba njani kwaye kwiyiphi idosi yevithamin D enokunyusa ukuchuma kunye nokuveliswa kwehomoni, "kusho uGqr Lechbaum Ukuba i-vitamin D ithathelwa ingqalelo, oku kunokubangela ukuba kutsha ngokupheleleyo. iindlela zonyango.”
Kakade ke, ukunqongophala kwevithamin D ayikuphela kwesizathu sokunciphisa ukuchuma. Kwimeko nayiphi na into, kufuneka ibe yinxalenye yonyango ukwandisa ukuchuma.
