Kuyezetsa magazi kwa Vitamini A.

Kuyesa kwa vitamini A kumayeza kuchuluka kwa vitamini A m'magazi.

Muyenera kuyesa magazi.

Tsatirani malangizo a omwe amakupatsani zaumoyo wosadya kapena kumwa chilichonse mpaka maola 24 mayeso asanayesedwe.

Pamene singano imayikidwa kuti ikoke magazi, anthu ena amamva kupweteka pang'ono. Ena amangomva kubaya kapena kuluma. Pambuyo pake, pangakhale kupunduka kapena kuvulala pang'ono. Izi posachedwa zichoka.

Kuyesaku kumachitika kuti muwone ngati muli ndi vitamini A wambiri kapena wocheperako m'magazi anu. (Izi sizachilendo ku United States.)

Makhalidwe abwinobwino amachokera pa ma micrograms 20 mpaka 60 pa deciliter (mcg / dL) kapena 0.69 mpaka 2.09 micromoles pa lita (micromol / L).

Mitengo yamtengo wapatali imatha kusiyanasiyana pakati pa ma labotore osiyanasiyana. Ma lab ena amagwiritsa ntchito miyeso yosiyanasiyana kapena amayesa mitundu yosiyanasiyana. Lankhulani ndi dokotala wanu tanthauzo la zotsatira zanu zoyesa.

Kutsika kuposa mtengo wabwinobwino kumatanthauza kuti mulibe vitamini A wokwanira m'magazi anu. Izi zitha kuyambitsa:

• Mafupa kapena mano omwe samakula bwino
• Maso owuma kapena otupa
• Kumva kukwiya kwambiri
• Kutaya tsitsi
• Kutaya njala
• Khungu usiku
• Matenda obwerezabwereza
• Ziphuphu pakhungu

Kuposa mtengo wanthawi zonse kumatanthauza kuti muli ndi vitamini A wochuluka m'magazi anu (poizoni). Izi zitha kuyambitsa:

• Kuchepa kwa magazi m'thupi
• Kupweteka kwa mafupa ndi minofu
• Kutsekula m'mimba
• Masomphenya awiri
• Kutaya tsitsi
• Kuwonjezeka kwa kupanikizika mu ubongo (pseudotumor cerebri)
• Kupanda kulumikizana kwa minofu (ataxia)
• Kukula kwa chiwindi ndi ndulu
• Kutaya njala
• Nseru

Kuperewera kwa Vitamini A kumatha kuchitika ngati thupi lanu likulephera kuyamwa mafuta kudzera munjira yogaya chakudya. Izi zikhoza kuchitika ngati muli ndi:

• Matenda am'mapapo otchedwa cystic fibrosis
• Mavuto am'mimba, monga kutupa ndi kutupa (kapamba) kapena limba osapanga ma enzyme okwanira (kapamba kosakwanira)
• Matenda ang'onoang'ono amatumbo omwe amatchedwa matenda a celiac

Pali chiopsezo chochepa chotenga magazi anu. Mitsempha ndi mitsempha imasiyana mosiyanasiyana kuchokera pa munthu wina kupita kwina komanso kuchokera mbali imodzi ya thupi kupita mbali inayo. Kutenga magazi kuchokera kwa anthu ena kumatha kukhala kovuta kuposa ena.

Zowopsa zina zomwe zimakhudzidwa ndikutengedwa magazi ndizochepa koma mwina ndi izi:

• Kutaya magazi kwambiri
• Ma punctures angapo kuti mupeze mitsempha
• Kukomoka kapena kumva mopepuka
• Hematoma (magazi akuchuluka pansi pa khungu)
• Kutenga (chiopsezo chochepa nthawi iliyonse khungu likasweka)

Mayeso a Retinol

• Kuyezetsa magazi
