Imiphumela Engaba Khona Yezithasiselo ze-Vithamini B12
Ngokuvamile, izithasiselo ze-vithamini B12 ezinconyiwe ngaphansi kokuqondisa kukadokotela zithathwa njengeziphephile. Nokho, kwabanye abantu, ukusetshenziswa ngokweqile noma okungadingekile kungaholela kule miphumela elandelayo:
Ukuba nesiyezi esincane kanye nezinkinga zokugaya ukudla
Ukuvela kwezilonda esikhumbeni, ukubomvu noma ukuluma
Ukhanda noma isiyezi
Isifo sohudo esincane
Ukungahleleki kokulala noma ukungalali
Ngokungajwayelekile, ukucindezeleka, ukungakhululeki, ukuthukuthela kanye nesimo sengqondo esidangele
Ngokungajwayelekile, umfutho wegazi ophakeme (i-hypertension) kanye nokushaya kwenhliziyo okusheshayo
Ngokocwaningo oluthile, ukuthatha i-vithamini B12 ngokweqile noma okungadingekile kungaholela ezinkingeni zokugaya ukudla, ikhanda elibuhlungu njalo, izinkinga zesikhumba kanye nezinguquko esimweni sengqondo kwabanye abantu. Kuphinde kwabikwa ukuthi, ngezinga eliphansi futhi okungavamile, kunezingozi ezandayo ezihlobene nohlelo lwezitho zenhliziyo nemithambo yegazi. Ngenxa yalokho, kubalulekile ukubonana nodokotela ngaphambi nangenkathi usebenzisa izithasiselo.
Izithasiselo ze-Vithamini B12 Ngesikhathi Sokukhulelwa
Ngesikhathi sokukhulelwa, isidingo se-B12 singakhula, ngakho udokotela wakho angancoma ukuhlolwa kwegazi ukuze anqume ukuthi kudingeka yini isithasiselo se-B12 ngesikhathi sokukhulelwa. Ukusebenzisa iphilisi le-B12 ngokweqile noma okungadingekile ngesikhathi sokukhulelwa kungaholela emiphumeleni emifushane efana nesiyezi, isicanucanu, izinkinga ezincane zokugaya ukudla, ukungezwani, ukusabela kwesikhumba kanye nobuthakathaka. Ngesikhathi sokukhulelwa, zama ukuthola i-vithamini B12 ngokudla kwemvelo (amaqanda, imikhiqizo yobisi, inyama kanye nemikhiqizo yasolwandle). Uma kunconywa isithasiselo, sebenzisa kuphela umthamo onikezwe udokotela wakho nangaphansi kokuqondisa kwakhe. Uma uhlangabezana nanoma yimiphi imiphumela engemihle, xhumana nodokotela wakho.
Ukweqisa I-Vithamini B12 kanye Nemiphumela Yako
Yize umzimba uvame ukukhipha i-vithamini B12 eningi ngomchamo, ukusetshenziswa okungaqondile nokwesikhathi eside kwemithamo ephezulu kungaholela emiphumeleni engafuneki kwabanye abantu. Izingozi ezihlobene nokusetshenziswa ngokweqile isikhathi eside zingabandakanya ukwanda kwengozi yezifo zenhliziyo nemithambo yegazi, isifo sokuqina komzimba kanye nezehlakalo zenhliziyo ezingazelelwe. Lezi zingozi azifani kubo bonke abantu; kodwa indlela ejwayelekile iwukuthi izithasiselo ze-B12 kufanele zisetshenziswe kuphela uma kudingeka, ngaphansi kokuqondisa kukadokotela futhi zilandelwe ngokuhlolwa kwegazi.
Izinga le-Vithamini B12 Lilinganiswa Kanjani?
Izinga le-vithamini B12 emzimbeni lingalinganiswa kalula ngokuhlolwa kwegazi. Isampula yegazi ivame ukuthathwa ngemva kokuzila ukudla amahora angu-6-8. Umphumela wokuhlolwa uzobikwa yilebhu; leli nani livame ukuvezwa njengama-pikogramu/ml (pg/mL). Emhlabeni jikelele, amalebhu amaningi athatha uhla olungu-200-800 pg/mL njenge-"evamile". Ngaphansi kuka-200 pg/mL kuthathwa njengokuntuleka, ngaphezu kuka-800 pg/mL kuthathwa njengokweqile. Le mikhawulo iyisiqondiso esijwayelekile; incazelo yemiphumela kufanele ihlaziywe udokotela wakho ngokwesimo sakho siqu.
Yiziphi Izinto Okufanele Uzinake Ngaphambi Kokusebenzisa Futhi Ngesikhathi Sokusebenzisa Izithasiselo ze-B12?
Ungaqali ukusebenzisa isithasiselo se-vithamini B12 wedwa, ngaphandle kwephepha likadokotela noma ukuhlolwa kwegazi.
Landela umthamo nesikhathi esinconyiwe udokotela wakho.
