I-Vitamin D iyaziwa ngokuthi "i-vitamin ye-sun" ngoba umzimba wethu uyayifaka lapho ivuleka emisebeni yelanga ye-ultraviolet. Nakuba ukutholakala kwevithamini D kuye kwahlotshaniswa ngokomlando nempilo emathambo empofu, manje kutholakala ukuthi ukutholakala kwamavithamini D kubambe iqhaza kwezinye izimo zezempilo, kuhlanganise ne- multiple sclerosis .
I-Vitamin D ne-Multiple Sclerosis
Mhlawumbe uzwile ucwaningo ukuthi amazinga aphansi e-vitamin D angakhuphula ingozi yomuntu yokuthuthukisa i-MS.
Lokhu kuxhumano kuvela eziningana zezifundo zesayensi ezathola ukuthi abantu abanokukhanya okukhanya okukhawulelwe, njengalabo abahlala ezindaweni ezisenyakatho, bajwayele ukuthola MS.
Ngaphezu kwe-vitamin D ehlobene nokuthuthukiswa kwe-MS , abanye ochwepheshe bakholelwa ukuthi izinga lomuntu we-Vitamin D lingathinta futhi umsebenzi wabo wesifo se-MS uma kutholakala ukuthi, njengokuthi bavame ukuphindaphinda kanjani nokuthi bakhubazekile kanjani. Ukusekela le mbono ukuthi ama-MS aphinde aphinde abuyele entwasahlobo lapho amazinga e-vitamin D afinyelele kuwo aphansi kakhulu (ngemuva kokuba izitolo ziphelile kusukela ebusika).
Futhi ukuqhubeka nokusekela indima ye-vitamin D e-MS, ososayensi bathole ukuthi i-vitamin D igciwane emzimbeni wethu itholakala kulesisindo esihlobene ne-MS nezinye izakhi zofuzo ezithintekayo ohlelweni lwethu lokuzivikela omzimba.
Ngaphezu kwalokho, ucwaningo lwamuva oluthile ezilwaneni lwathola ukuthi i-vitamin D ingadlala indima ekwakheni i-myelin sheath.
Kulolu cwaningo, i-vitamin D receptor yatholakala ukuthi ibhekene neprotheyini ehilelekile ekulawuleni amangqamuzana enza i-myelin (lawa maseli abizwa ngokuthi ama-oligodendrocyte).
Okubalulekile ukuthi lolu cwaningo luphakamisa ukuthi i-vitamin D ingabangela ukubuyiswa kwe-myelin. Yiqiniso, izifundo eziningi (kufaka phakathi abantu) zidinga ukucacisa lokhu okutholile.
Kungakhathaliseki ukuthi, kugcizelela ukuthi kubaluleke kakhulu ukuthi i-vitamin D idlala ku-MS impilo.
Nakuba indima eqondile i-vitamin D edlala ku-MS isacacile (ikakhulukazi indima edlalayo ekuqhubeleni kwesifo se-MS), izindaba ezinhle ukuthi ososayensi bayaqhubeka nokuphenya ngokuqhubekayo.
Ubufakazi buphoqelela ngokwanele ngalesi sikhathi ukuthi ukuthatha u-vitamin D noma ukuhlolwa kwezinga ukucacisa ukuthi kunesidingo esikhona kubonakala kunengqondo.
Ezinye Izinzuzo Zamavithamini D Nge-Multiple Sclerosis
Esinye isizathu sokubheka amazinga e-vitamin D kubantu abane-MS ukuthi, ngaphezu kokumisa inkambo yesifo somuntu we-MS, siyazi ukuthi i-vitamin D ibalulekile empilweni yethambo lomuntu, elingase libekwe eceleni kwe-multiple sclerosis.
I-osteoporosis , isimo esibonakala ngethambo elibuthakathaka nokulahlekelwa, livamile kubantu abane-MS, ngenxa yezici eziningana ezifana nokusetshenziswa okungavamile kwe-corticosteroid , ukugwema ukushisa kwelanga (ukushisa), nokunciphisa ukuhamba. Ukuvimbela ukuhlinzeka ngokwe-osteoporosis, iziguli ngokuvamile zeluleka ukuba zandise i-vitamin D ne-calcium ekudleni kwazo noma ngeziqu. Futhi, ukuvivinya umzimba , ukuqeda ukubhema, nokunciphisa utshwala kubalulekile ekuqiniseni amathambo akho.
Kufanele ngithathe i-Vitamin D uma ngine-MS?
Kubantu abaningi, i-United States neCanada Institute of Medicine bacabangela izinga levithamini D 50nmol / L noma ngaphezulu ukuze lwanele.
Kodwa, kubalulekile ukuqonda ukuthi izinga eliphakeme akusilo kangcono, njengoba izinga le-vitamin D elingaphezulu kuka-125nmol / L lingalimaza umuntu.
Ngesikhathi ucwaningo lubonisa ukuthi ukuthatha u-4000 IU nsuku zonke nge-vitamin D noma ngaphansi kungabangela noma yimiphi imiphumela emibi, kubalulekile ukuthi ungathathi i-vitamin D noma usebenzise imithombo yokudla ephezulu kakhulu ku-vitamin D (isibonelo, i-cod fover oil ) ngaphandle kokuqala ukuxoxa nodokotela wakho.
Khumbula futhi, ayikho isiqondiso esithile esitshela ukuthi abantu abane-MS kufanele bathathe i-vitamin D futhi uma kunjalo, kungakanani. Lokho kusho, odokotela abaningi babona inzuzo engaba khona.
Futhi, iqiniso lokuthi libekezelela kahle futhi libonakala liphephile ngaphandle uma lithathwa ngokwezinga eliphezulu kakhulu liphinde lithande.
Izwi elivela
Ungamangali uma udokotela wakho ekhomba ukuhlola izinga lakho le-vitamin D-futhi uma engakafiki, cabanga ngokuyikhuphula ekuqeshweni okulandelayo.
