Ukuhlolwa kwegazi likaVithamini A

Ukuhlolwa kukavithamini A kukala izinga likavithamini A osegazini.

Kudingeka isampula yegazi.

Landela imiyalo yomhlinzeki wakho wezokunakekelwa kwempilo mayelana nokungadli noma ukuphuza noma yini kuze kube ngamahora angama-24 ngaphambi kokuhlolwa.

Lapho inaliti ifakwa ukudonsa igazi, abanye abantu bezwa ubuhlungu obulinganiselayo. Abanye bazizwa beshaywa noma betinyelwa kuphela. Ngemuva kwalokho, kungahle kube nokushaywa okuthile noma ukulinyazeka okuncane. Lokhu maduzane kuyaphela.

Lokhu kuhlolwa kwenzelwa ukubheka ukuthi unovithamini A omningi noma omncane kakhulu egazini lakho. (Lezi zimo azivamile e-United States.)

Amanani ajwayelekile avela kuma-micrograms angama-20 kuye kwangama-60 nge-deciliter ngayinye (mcg / dL) noma ku-0.69 kuye ku-2.09 micromoles ngelitha ngalinye (micromol / L).

Ububanzi bamanani ajwayelekile bungahluka kancane phakathi kwamalabhorethri ahlukene. Amanye amalebhu asebenzisa izilinganiso ezahlukahlukene noma avivinye amasampula ahlukile. Khuluma nodokotela wakho mayelana nencazelo yemiphumela yakho ethile yokuhlolwa.

Inani eliphansi kunokujwayelekile lisho ukuthi awunavithamini A owanele egazini lakho. Lokhu kungadala:

• Amathambo noma amazinyo angakhuli kahle
• Amehlo awomile noma avuvukele
• Ukuzizwa uthukuthele ngokwengeziwe
• Ukulahleka kwezinwele
• Ukuphelelwa isifiso sokudla
• Ubumpumputhe basebusuku
• Izifo eziphindaphindayo
• Ukuqhuma kwesikhumba

Inani eliphakeme kunokujwayelekile lisho ukuthi une-vitamin A eyeqile egazini lakho (amazinga anobuthi). Lokhu kungadala:

• Ukushoda kwegazi
• Ubuhlungu bamathambo nemisipha
• Uhudo
• Umbono ophindwe kabili
• Ukulahleka kwezinwele
• Ukwanda kwengcindezi ebuchosheni (pseudotumor cerebri)
• Ukungabi nokuhlanganiswa kwemisipha (ataxia)
• Ukwandiswa kwesibindi nobende
• Ukuphelelwa isifiso sokudla
• Isicanucanu

Ukushoda kukavithamini A kungenzeka uma umzimba wakho unenkinga yokumunca amafutha ngomgudu wokugaya ukudla. Lokhu kungenzeka uma une:

• Isifo samaphaphu esingapheli esibizwa ngecystic fibrosis
• Izinkinga zepancreas, njengokuvuvukala nokuvuvukala (i-pancreatitis) noma isitho esingakhiqizi ama-enzyme anele (ukungasebenzi kahle kwe-pancreatic)
• Ukuphazamiseka kwamathumbu amancane okubizwa ngesifo se-celiac

Kunengozi encane ethintekayo ekuthatheni igazi lakho. Imithambo nemithambo yegazi kuyahluka ngosayizi komunye umuntu kuya kolunye uhlangothi lomzimba kuya kolunye. Ukuthatha igazi kwabanye abantu kungaba nzima kakhulu ukwedlula kwabanye.

Ezinye izingozi ezihambisana nokudonswa igazi zincane kepha zingafaka:

• Ukopha ngokweqile
• Ukubhoboza okuningi ukuthola imithambo
• Ukuquleka noma uzizwe unekhanda elincane
• I-hematoma (ukuqoqwa kwegazi ngaphansi kwesikhumba)
• Ukutheleleka (ingozi encane noma kunini lapho isikhumba siphukile)

Ukuhlolwa kwe-Retinol

• Ukuhlolwa kwegazi
