Uvavanyo lwegazi lweVitamin A

Uvavanyo lwevithamini A lilinganisa inqanaba levithamini A egazini.

Isampulu yegazi iyafuneka.

Landela imiyalelo yomboneleli wakho wezempilo malunga nokungatyi okanye ukusela nantoni na ukuya kuthi ga kwiiyure ezingama-24 ngaphambi kovavanyo.

Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukuphazamiseka okanye ukugruzuka okuncinci. Oku kuya kuhamba kungekudala.

Olu vavanyo lwenziwa ukujonga ukuba unevithamini A eninzi okanye encinci kakhulu egazini lakho. (Le miqathango ayiqhelekanga eUnited States.)

Amaxabiso aqhelekileyo aqala kwi-20 ukuya kwi-60 micrograms ngedesilitha nganye (mcg / dL) okanye i-0.69 ukuya kwi-2.09 micromoles kwilitha nganye (micromol / L).

Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Ezinye iilebhu zisebenzisa imilinganiselo eyahlukeneyo okanye ukuvavanya iisampulu ezahlukeneyo. Thetha nogqirha wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Ixabiso elingaphantsi kweqhelekileyo lithetha ukuba awunayo i-vitamin A eyaneleyo egazini lakho. Oku kunokubangela:

• Amathambo okanye amazinyo angakhuli kakuhle
• Amehlo owomileyo okanye adumbileyo
• Ndiziva ndicaphuka ngakumbi
• Ukulahleka kweenwele
• Ukuphelelwa ngumdla wokutya
• Ubumfama ebusuku
• Izifo ezenzeka rhoqo
• Irhashalala

Ixabiso elingaphezulu kweqhelekileyo lithetha ukuba une-vitamin A engaphezulu kwegazi lakho (amanqanaba anetyhefu). Oku kunokubangela:

• Ukunqongophala kwegazi
• Intlungu yethambo kunye nezihlunu
• Urhudo
• Umbono kabini
• Ukulahleka kweenwele
• Ukonyusa uxinzelelo kwingqondo (pseudotumor cerebri)
• Ukungabikho kokulungelelaniswa kwemisipha (ataxia)
• Ukwandiswa kwesibindi kunye nepeni
• Ukuphelelwa ngumdla wokutya
• Isicaphucaphu

Ukusilela kweVitamin A kunokwenzeka ukuba umzimba wakho unengxaki yokufunxa amafutha ngendlela yokugaya ukutya. Oku kunokwenzeka ukuba une:

• Isifo esingapheliyo semiphunga esibizwa ngokuba yicystic fibrosis
• Iingxaki zepancreas, ezinje ngokudumba kunye nokudumba (i-pancreatitis) okanye ilungu elingavelisi ii-enzymes ezaneleyo (ukungonelanga kwepancreatic)
• Ukuphazamiseka kwamathumbu amancinci okubizwa ngokuba sisifo se-celiac

Akukho mngcipheko ubandakanyekileyo ekuthatheni igazi lakho. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka komnye umntu ukuya komnye nakwelinye icala lomzimba liye kwelinye. Ukuthatha igazi kwabanye abantu kunokuba nzima ngakumbi kunabanye.

Eminye imingcipheko enxulumene nokutsalwa kwegazi incinci kodwa inokubandakanya:

• Ukopha kakhulu
• Ukugqobhoza okuninzi ukufumana imithambo
• Ukufa isiqaqa okanye ukuziva ungenantloko
• I-Hematoma (igazi eliqokelela phantsi kwesikhumba)
• Usulelo (umngcipheko omncinci nangaliphi na ixesha ulusu lwaphukile)
