Ngaba nawe uziva udiniwe imini yonke? Ngaba uziva ubuthathaka kwaye ungenabomi? Ngaba ngamanye amaxesha uziva ngathi iminwe neenzwane zakho azinangqondo, okanye uziva ngathi utyiwa ziimbovane? Uninzi lwethu luyazityeshela ezi zinto, lucinga ukuba ziqhelekile. Kodwa ezi zinokuba ziimpawu ezincinci zokuba unesiphene sevithamini B12, nto leyo ethetha ukuba umzimba wakho awufumani ngokwaneleyo ivithamini B12 oyidingayo. Ngoko ke, namhlanje siza kuthetha ngovavanyo olukhethekileyo olunokukunceda ufumanise ukuba unayo na le meko. Leyo yi-methylmalonic acid, okanye uvavanyo lwe-MMA ngamafutshane.
Yintoni uvavanyo lwe-methylmalonic acid (MMA)?
Ngamafutshane, uvavanyo lwe-methylmalonic acid (MMA) luvavanyo lwegazi okanye lomchamo olujonga ukungabikho kwe-vitamin B12 emzimbeni wakho.
Cinga ngale ndlela. I-Vitamin B12 ibalulekile kwiiseli zomzimba wethu, ingakumbi kwinkqubo yemithambo-luvo nasekuveliseni iiseli ezibomvu zegazi. Njengokuba imoto ifuna ipetroli ukuze isebenze, i-vitamin B12 ibalulekile kwiinkqubo ezithile ezibalulekileyo emzimbeni wethu.
Ngoku, xa amanqanaba ethu evithamini B12 ephantsi, okanye xa i-B12 esiyithathayo ingafunxwa kakuhle, ezinye iinkqubo zeekhemikhali emzimbeni wethu ziyayeka ukusebenza. Ngenxa yoko, ikhemikhali ebizwa ngokuba yi-"methylmalonic acid" (MMA) iqala ukuqokelelana emzimbeni.
Ukuchaneka, i-vitamin B12 ifana nomsebenzi osusa "inkunkuma" ebizwa ngokuba yi-MMA emzimbeni wethu. Xa umsebenzi we-B12 engekho, okanye xa engakwazi ukwenza umsebenzi wakhe, le nkunkuma ye-MMA iqokelelana egazini nasemchameni. Ngoko ke ugqirha wakho uza kuvavanya isampuli yegazi okanye yomchamo wakho ukuze abone ukuba inqanaba le-MMA liphezulu. Ukuba inqanaba liphezulu, oko kuthetha ukuba usenokuba awunayo i-vitamin B12.
Kutheni kufuneka ndithathe olu vavanyo lwe-MMA?
Kukho izizathu ezininzi eziphambili zokuba ugqirha wakho angayalela olu vavanyo. Makhe sijonge ukuba zeziphi.
| Isizathu sovavanyo | Inkcazo |
|---|---|
| Ukuba neempawu zokunqongophala kwe-vitamin B12 | Ukuba unale mpawu, ugqirha wakho unokukuthumela kolu vavanyo:
|
| Kwabasandul' ukuzalwa | Olu vavanyo lusetyenziselwa ukufumanisa ukuba iintsana ezisandul’ ukuzalwa zine -methylmalonic acidemia , imeko engaqhelekanga yemfuza. Oku kudla ngokwenziwa esibhedlele kungekapheli usuku okanye ezimbini emva kokuzalwa. |
Ukunqongophala kweVitamin B12 asinto ilula. Ukuba kuqhubeka ixesha elide, kunokubangela umonakalo kwimithambo-luvo . Kungakhokelela nakwiimeko ezifana ne-anemia eyingozi . Ke ngoko, kubaluleke kakhulu ukuyifumanisa nokuyinyanga kwangethuba.
Kutheni kufuneka uvavanye i-MMA ngaphandle kokujonga ngqo amanqanaba e-B12?
Lo ngumbuzo abantu abaninzi abanawo. Usenokuba uzibuza, "Ukuba ungajonga amanqanaba akho e-B12 ngqo egazini lakho, kutheni ujonge enye into ebizwa ngokuba yi-MMA?"
Nasi isizathu. Ngamanye amaxesha, amanqanaba e-B12 egazini lakho anokubonakala eqhelekile kwingxelo yakho. Kodwa eneneni, iiseli zomzimba wakho zisenokungakwazi ukusebenzisa loo B12. Oku kubizwa ngokuba yi -bioavailability ephantsi.
Ngamafutshane, itanki yakho yamanzi ekhaya isenokuba igcwele amanzi. Kodwa ukuba impompo iphukile, awunakuyisebenzisa loo manzi. Yiloo nto eyenzekayo nalapha. Nokuba une-B12 egazini lakho, ayincedi nganto ukuba iiseli zakho azikwazi ukuyisebenzisa.
Ngoko ke, nokuba i-B12 ayinakusetyenziswa, loo nkunkuma ebizwa ngokuba yi-MMA ebesithethe ngayo ngaphambili iqokelelana emzimbeni. Ke ngoko, ngokujonga inqanaba le-MMA, ugqirha unokufumana umfanekiso ochanekileyo ngakumbi . Oku kuthetha ukuba uvavanyo lwe-MMA alunakufumanisa kuphela ukuba umzimba wakho une-B12, kodwa lukwafumana nokuba isetyenziswa ngokufanelekileyo na . Olu luncedo olukhulu ekuchongeni ukungabikho kwe-B12 kwasekuqaleni.
Lwenziwa njani olu vavanyo kwaye ndifanele ndilungiselele ntoni?
Ukuze wenze uvavanyo lwe-MMA, uza kucelwa ukuba unike isampuli yegazi okanye yomchamo. Ugqirha wakho uza kugqiba ukuba uza kukwenza njani oku.
Ukulungiselela ngaphambi kovavanyo
Oku kunokwahluka ngokuxhomekeke kwindlela yovavanyo emiselweyo kuwe.
- Ukuba uvavanywa igazi, ungacelwa ukuba uzile ukutya iiyure ezimbalwa , oko kuthetha ukuba awuyi kutya okanye usele nantoni na.
- Ukuba uvavanyo lomchamo lwenziwa iiyure ezingama-24, ungacetyiswa ukuba uyeke ukutya okanye amayeza athile ngaloo mini.
Eyona nto ibalulekileyo kukubuza ugqirha wakho okanye elebhu ngale nto uze ulandele imiyalelo yakhe.
Indlela yokwenza uvavanyo
| Indlela yovavanyo | Indlela yokwenza oko |
|---|---|
| Uvavanyo lweGazi | Oku kufana nokunika igazi eliqhelekileyo. Kwilabhoratri, kusetyenziswa isirinji encinci ukutsala igazi elincinci kumthambo osengalweni yakho, kufutshane nengqiniba yakho. Emva koko, kufakwa iplasta encinci kuloo ndawo. |
| Isampulu yomchamo yeeyure ezingama-24 | Ilebhu iza kukunika ibhotile ekhethekileyo. Uza kuyalelwa ukuba uqokelele wonke umchamo wakho ebhotileni iiyure ezingama-24. Emva koko kufuneka uyise ibhotile kwilebhu. |
| Isampuli yomchamo eqhelekileyo (Uhlalutyo lomchamo) | Oku kuquka ukudlulisa umchamo omncinci kwikomityi encinci necocekileyo oza kuyinikwa. Oku kungenziwa ekhaya okanye kwiofisi kagqirha wakho. |
| Kwabasandul' ukuzalwa | Esibhedlele, umongikazi oqeqeshiweyo uhlaba isithende somntwana ngenaliti encinci aze aqokelele amathontsi ambalwa egazi kwikhadi elikhethekileyo. Oku akubuhlungu kakhulu kumntwana. |
Ungaqhubeka nemisebenzi yakho yesiqhelo emva kovavanyo. Kungathatha naphi na ukusuka kusuku ukuya kwiveki okanye ezimbini ukufumana iziphumo.
Ungaziqonda njani iziphumo?
Xa ufumana ingxelo yakho yelebhu, iya kubandakanya ixabiso le-MMA.
- Amaxabiso aqhelekileyo:La maxabiso anokwahluka kancinci ngokwelabhoratri nganye. Ngokwesiqhelo, amanqanaba e-MMA eserum kufuneka abe ngaphantsi kwe -0.40 µmol/L . Nangona kunjalo, kungcono ukujonga icandelo elithi "Reference Range" kwingxelo yakho.
Kuza kwenzeka ntoni ukuba inqanaba le-MMA liyanyuka?
- Ukuba inqanaba lakho le-MMA liphezulu: Oku kubonisa ukuba usenokuba une-vitamin B12 enqongopheleyo. Ugqirha wakho mhlawumbi uza kwenza ezinye iimvavanyo, ezifana ne -homocysteine , aze adibanise zonke ezi ziphumo ukuze afikelele kwisigqibo. Emva koko uza kukunika unyango olufunekayo, umzekelo, iipilisi ze-vitamin B12 okanye iinaliti.
- Ukuba usana olusandul’ ukuzalwa lunamanqanaba aphezulu e-MMA: Kungaba luphawu lwesifo semfuza esibizwa ngokuba yi-methylmalonic acidemia . Ugqirha uya kuyalela iimvavanyo ezongezelelweyo ukuqinisekisa ukuxilongwa. Ukuba imeko ikhona, unyango luquka ukutya okukhethekileyo kunye nezongezo zeevithamini.
Ngaba amanqanaba e-MMA anokunyuswa nokuba amanqanaba e-B12 aqhelekile?
Ewe, unako. Le yeyona nxalenye ibalulekileyo yolu vavanyo. Ukuba amanqanaba e-B12 egazini lakho aqhelekile kodwa amanqanaba akho e-MMA aphakanyisiwe, oko kuthetha ukuba une -B12 esezantsi okanye encinci eswelekileyo . Oku kuthetha ukuba umzimba wakho une-B12 kodwa awuyisebenzisi kakuhle. Ugqirha wakho uya kugqiba ukuba ufuna unyango okanye akunjalo.
Ndifanele ndimbone nini ugqirha?
- Ukuba uneempawu zokungabikho kwevithamini B12 esizixubushileyo ngaphambili (ukudinwa, ukuba ndindisholo, njl.njl.), qiniseka ukuba ubonana nogqirha wakho.
- Ukuba unemibuzo okanye ubunzima bokuqonda iziphumo zovavanyo ozifumeneyo, thetha nogqirha wakho ngaloo nto.
Ngamanye amaxesha, ulwazi malunga nengxaki kwenye inxalenye yomzimba wethu lunokufunyanwa kwenye inxalenye. Uvavanyo lwe-MMA lolunye lolo vavanyo. Ngokulinganisa inqanaba le-MMA egazini okanye emchameni, sinokufumanisa ukuba i-vitamin B12 isebenza kakuhle na ngaphakathi kwiiseli zomzimba wethu. Eli lithuba elixabisekileyo lokuchonga nokuqala unyango lwezifo ngaphambi kokuba kwenzeke umonakalo wemithambo-luvo. Ke ngoko, musa ukuzibamba nto kwaye uthethe nogqirha wakho ngale nto.
Umyalezo Wokuya Ekhaya
- Uvavanyo lweMethylmalonic Acid (MMA) luvavanyo olubaluleke kakhulu nolunobuzaza lokufumanisa ukungabikho kwevithamini B12.
- Nokuba amanqanaba e-B12 egazini lakho aqhelekile, ukuba umzimba awusebenzisi loo B12, inokubonwa ngovavanyo lwe-MMA.
- Musa ukungazinaki iimpawu ezinje ngokudinwa rhoqo, ubuthathaka, kunye nokuba ndindisholo kwamalungu akho njengesiqhelo. Zingaba ziimpawu ezibalulekileyo zokuba ufanele ubonane nogqirha.
- Ukuba unenkxalabo malunga neziphumo zovavanyo lwakho okanye iimpawu, qiniseka ukuba uthetha nogqirha wakho. Ungaze uthembele kwiingxelo zelebhu ukuze ufumanise imeko.
