Yintoni i-hemoglobin (Hgb, Hb)?

I-Hemoglobin (Hgb, Hb) yiproteni ekwiiseli ezibomvu zegazi ethwala ioksijini esuka kwimiphunga iye kwizicubu zomzimba wakho ize ibuyisele i-carbon dioxide esuka kwizicubu iye kwimiphunga yakho.

I-Hemoglobin yenziwe ngeemolekyuli ezine zeproteni (ii-globulin chains) ezidityaniswe kunye. Ikhonkco ngalinye le-globulin liqulathe i-porphyrin compound ebalulekileyo equlethe i-iron ebizwa ngokuba yi-heme. Kwi-heme compound kukho i-athomu ye-iron ebalulekileyo ekuthuthweni kwe-oksijini kunye ne-carbon dioxide egazini lethu. I-iron ekwi-hemoglobin ikwanoxanduva lombala obomvu wegazi.

I-hemoglobin ikwadlala indima ebalulekileyo ekugcineni imilo yeeseli ezibomvu zegazi. Kwimilo yazo yendalo, iiseli ezibomvu zegazi zingqukuva kwaye zinendawo ezimxinwa ezifana nedonathi engenamngxuma embindini. Ulwakhiwo olungaqhelekanga lwe-hemoglobin, ke ngoko, lunokuphazamisa imilo yeeseli ezibomvu zegazi kwaye luphazamise ukusebenza kwazo kunye nokuhamba kwazo kwimithambo yegazi.

Kutheni yenziwe

Usenokuba novavanyo lwe-hemoglobin ngezizathu ezahlukeneyo:

Ukujonga impilo yakho iyonke.Ugqirha wakho unokuvavanya i-hemoglobin yakho njengenxalenye yokubala igazi ngokupheleleyo ngexesha lovavanyo lwezonyango oluqhelekileyo ukuze ajonge impilo yakho ngokubanzi kwaye ahlole iingxaki ezahlukeneyo, ezifana ne-anemia.
Ukufumanisa imeko yempilo.Ugqirha wakho unokucebisa uvavanyo lwe-hemoglobin ukuba ubuthathaka, ukudinwa, ukuphefumla okufutshane okanye isiyezi. Ezi mpawu zinokubonisa i-anemia okanye i-polycythemia vera. Uvavanyo lwe-hemoglobin lunokunceda ekufumaneni ezi okanye ezinye iimeko zonyango.
Ukubeka esweni imeko yempilo.Ukuba ufunyaniswe une-anemia okanye i-polycythemia vera, ugqirha wakho angasebenzisa uvavanyo lwe-hemoglobin ukujonga imeko yakho kunye nokukhokela unyango.

Zintoni iieqhelekileyoamanqanaba e-hemoglobin?

Inqanaba le-hemoglobin lichazwa njengobungakanani be-hemoglobin kwiigram (gm) nge-deciliter (dL) yegazi liphela, i-deciliter yi-100 milliliters.

Iindidi eziqhelekileyo ze-hemoglobin zixhomekeke kubudala, kwaye, ukususela ebusheni, isini somntu. Iindidi eziqhelekileyo zezi:

Zonke ezi xabiso zinokwahluka kancinci phakathi kweelabhoratri. Ezinye iilabhoratri azihluli phakathi kwexabiso le-hemoglobin yabantu abadala kunye "nasemva kweminyaka ephakathi". Abafazi abakhulelweyo bayacetyiswa ukuba baphephe amanqanaba e-hemoglobin aphezulu naphantsi ukuze baphephe umngcipheko wokuzalwa kwabantwana abaswelekileyo (i-hemoglobin ephezulu - ngaphezulu komlinganiselo oqhelekileyo) kunye nokuzalwa kwangaphambi kwexesha okanye usana olunobunzima obuphantsi (i-hemoglobin ephantsi - ngaphantsi komlinganiselo oqhelekileyo).

Ukuba uvavanyo lwe-hemoglobin lubonisa ukuba inqanaba le-hemoglobin yakho liphantsi kunesiqhelo, oko kuthetha ukuba une-anemia ephantsi. I-anemia inokuba nezizathu ezininzi ezahlukeneyo, kubandakanya ukungabikho kweevithamini, ukopha kunye nezifo ezingapheliyo.

Ukuba uvavanyo lwe-hemoglobin lubonisa inqanaba eliphezulu kuneliqhelekileyo, kukho izizathu ezininzi ezinokubakho - isifo segazi i-polycythemia vera, ukuhlala kwindawo ephakamileyo, ukutshaya kunye nokuphelelwa ngamanzi emzimbeni.

Iziphumo eziphantsi kunesiqhelo

Ukuba inqanaba le-hemoglobin yakho liphantsi kunesiqhelo, une-anemia. Kukho iintlobo ezininzi ze-anemia, nganye inezizathu ezahlukeneyo, ezinokuquka:

Ukunqongophala kwesinyithi
Ukunqongophala kweVithamin B-12
Ukunqongophala kwe-folate
Ukopha
Umhlaza ochaphazela umongo wethambo, njenge-leukemia
Isifo sezintso
Isifo sesibindi
I-Hypothyroidism
I-Thalassemia — isifo semfuza esibangela amanqanaba aphantsi e-hemoglobin kunye neeseli ezibomvu zegazi

Ukuba sele ufunyenwe une-anemia, inqanaba le-hemoglobin eliphantsi kunesiqhelo linokubonisa ukuba kufuneka utshintshe isicwangciso sakho sonyango.

Iziphumo ziphezulu kunesiqhelo

Ukuba inqanaba le-hemoglobin yakho liphezulu kunesiqhelo, isenokuba ngumphumo we:

I-Polycythemia vera - isifo segazi apho umongo wakho wethambo wenza iiseli ezibomvu zegazi ezininzi kakhulu
Isifo semiphunga
Ukuphelelwa ngamanzi emzimbeni
Ukuhlala kwindawo ephakamileyo
Ukutshaya kakhulu
Ukutsha
Ukuhlanza okugqithisileyo
Ukuzilolonga umzimba kakhulu
