I-hemoglobin ephezulu - izimbangela

I-hemoglobin ephezulu kusho ukuthi okuqukethwe kwegazi kwamangqamuzana egazi abomvu kwanda. Ngisho nomuntu onempilo enhle, izinga le-hemoglobin lingashintsha ngokubanzi. Izinkomba ezijwayelekile ze-hemoglobin yilezi:

• abesifazane besilinganiso esingu 120-140 g / l (amagremu ngalinye ilitha legazi);
• kubantu - 135-160 g / l.

Uma ukudlula okwejwayelekile kungamayunithi angaphezu kwangu-20, singakhuluma ngokukhula kwe-hemoglobin.

I-hemoglobin iphakama nini?

Izizathu zokuqukethwe kwe-hemoglobin ephezulu egazini zingahlukaniswa ngokuthi:

• i-physiological;
• i-pathological.

Ukunyuka okukhulu kwe-hemoglobin kuyingozi ukuthi umzimba kuleso sikhukhula se-viscosity yegazi ingabangela ukuphazamiseka kwesifo noma isifo somzimba. Igazi lingasondeza ngenxa yokuphelelwa amandla kwamanzi emzimbeni ngesikhathi sokuhlanza nokuhuda. Lokhu kubangela ukwehla kwenani legazi elijikelezayo.

Umzimba uqala ukukhiqiza inani elikhuphukile lamaseli abomvu ebomvu ezinjalo:

1. Uma umzimba ungekho oksijeni ngenxa yobumpofu bawo, ukuthutha okwanele kwamathekithi.
2. Lapho umthambo wegazi we-plasma wehliswa kakhulu, okuholela ekuthuthukiseni inani elikhulu lamaseli abomvu obomvu.

Njengomthetho, izinga le-hemoglobin egazini landa:

1. Abantu abahlala phezulu ezintabeni noma emathafeni, kodwa phezulu ngaphezu kolwandle. Umoya awunqabile, okuqukethwe kwe-oksijini kuyancipha, nansi amangqamuzana omzimba futhi awutholakali oksijini futhi awubuyisele ngokukhiqiza okukhulu kwe-hemoglobin.
2. Ekuziphatheni okwemvelo - kubantu bezemidlalo abahlanganyela ezinhlobonhlobo zasebusika zezemidlalo, abagijimi, kanye nakwabazintaba.
3. Abantu abavame ukuhamba ngezindiza - abaqhubi, abaphathi.
4. Amadoda nabesifazane abashisa ngenkuthalo. Umzimba awunalo oksijeni ehlanzekile ngenxa yokugubha emaphashini bese uqala ukuthuthukisa amangqamuzana abomvu egazi.

Izimbangela zamazinga aphezulu e-hemoglobin egazini

Kunezizathu ezimbalwa ze-hemoglobin ephakeme. Lokhu kungenxa yokushintsha okwenzeka emzimbeni oneminyaka yobudala, kodwa futhi nangezinye izici eziningi.

Izimbangela eziyinhloko ze-hemoglobin eliphezulu egazini zingabizwa ngokuthi:

• i-glucose eyandayo e-diabetes mellitus;
• inani elikhulu le-hemoglobin e-plasma yegazi (i-hemoglobinemia);
• ukwakheka ngokweqile kwama-erythrocyte egazini (i-erythrocytosis);
• ukuqina kwegazi;
• izifo eziphilayo;
• ukuphefumula emathunjini ompofu;
• ukuhluleka kwenhliziyo;
• izifo zamaphaphu - i- pneumonia , i-bronchitis yobunzima obuhlukahlukene, isifo se-asthma, isifo sofuba, i-emphysema kanye nabanye.
• ukunqwabelana kwezinto eziphilayo zamavithamini weqembu "В" - В9, В12.

Izimbangela ze-hemoglobin ephezulu kwabesifazane abakhulelwe

Ekufikeni kokukhulelwa umzimba wesifazane uphinde wakhiwe kabusha, uqala ukuhlola amathonya amasha kuwo. Izinga le-hemoglobin liwela ngandlela-thile ngenxa yokuthi i-fetus ithatha insimbi ethile, futhi omama abazayo baqala ukwandisa nge-multivitamines ensimbi. Ngenxa yalokho, i-hemoglobin egazini iphakama ibe ngu-150-160 g / l. Kodwa kancane kancane igazi likhula, ingane iqala ukungabi ne-oksijeni nezakhi ngenxa yokusakaza okuncane kwegazi. Kuyinto engathandeki kakhulu ukuba ama- blood clots avele, ngakho-ke kubalulekile ukubonana nodokotela ngokushesha uma izinga le-hemoglobin lidlula u-150 g / l wegazi.

Isizathu sokwanda kwe-hemoglobin ngesikhathi sokukhulelwa kungase kube nzima kwezifo ezingapheli, ikakhulukazi inhliziyo kanye namaphaphu.

Indawo lapho owesifazane okhulelwe ehlala khona kungabangela nokunyuka kwe-hemoglobin. Njengoba kushiwo ngaphambili, ukuthola izinga eliphezulu elwandle kunomthelela ekukhiqizeni amaprotheni amaningi. Ungazitholi ngokweqile nokwenza ngokweqile ngokomzimba.
