1.Yintoni ihemoglobin?
IHemoglobin (efinyeziweyo i-Hgb okanye i-Hb) yimolekyuli yeprotini ekwiiseli ezibomvu zegazi ethwala ioksijini isuka emiphungeni iyise kwizicubu zomzimba ize ibuyisele ikharbon diokside esuka kwizicubu ibuyele emiphungeni.
IHemoglobin yenziwe ziimolekyuli ezine zeproteni (amatsheyina eglobulin) adityaniswe kunye.
Imolekyuli yehemoglobin yabantu abadala eqhelekileyo inamatyathanga amabini ealpha-globulin namatyathanga amabini ebeta-globulin.
Kwiimveku nakwiimveku, amatyathanga e-beta awaxhaphakanga kwaye imolekyuli ye-hemoglobin yenziwe ngamatyathanga amabini e-alpha kunye namatyathanga amabini egamma.
Njengoko usana lukhula, ngokuthe ngcembe amatyathanga e<em>gamma athatyathelw’ indawo ngamatyathanga e<em>beta, abumba i<em>hemoglobin yabantu abadala.
Itsheyini ngalinye leglobulin liqulethe i-iron ebalulekileyo yeporphyrin ebizwa ngokuba yiheme.Kwikhompawundi yeheme kukho iathom yentsimbi ebalulekileyo ekuthutheni ioksijini kunye nekharbon diokside egazini lethu.Iiron ekwihemoglobin ikwangunobangela wombala obomvu wegazi.
IHemoglobin ikwadlala indima ebalulekileyo ekugcineni imilo yeeseli ezibomvu zegazi.Ngokwemvelo yazo, iiseli ezibomvu zegazi zingqukuva kunye namaziko amxinwa afana ne-donut engenamngxuma phakathi.Ubume obungaqhelekanga be-hemoglobin, ke ngoko, bunokuphazamisa ukumila kweeseli ezibomvu zegazi kwaye zithintele ukusebenza kwazo kunye nokuhamba kwimithambo yegazi.
2.Ngawaphi amanqanaba e-hemoglobin aqhelekileyo?
Umlinganiselo oqhelekileyo wehemoglobin emadodeni uphakathi kwe-14,0 ne-17,5 yeegram ngedesilitha (gm/dL);kubafazi, kuphakathi kwe-12.3 kunye ne-15.3 gm/dL.
Ukuba isifo okanye imeko ichaphazela ukuveliswa komzimba kweeseli ezibomvu zegazi, amanqanaba e-hemoglobin anokwehla.Iiseli ezibomvu zegazi ezimbalwa kunye namanqanaba asezantsi e-hemoglobin anokubangela ukuba umntu abe ne-anemia.
3.Ngoobani abanokuthi babe neanemia yokusilela kwesinyithi?
Nabani na unokuhlakulela i-iron-deficiency anemia, nangona la maqela alandelayo anomngcipheko ophezulu:
Abasetyhini, ngenxa yokulahleka kwegazi ngexesha lenyanga kunye nokubeletha
Abantu abangaphezu kweminyaka engama-65, abanokuthi bafumane ukutya okune-iron ephantsi
Abantu abasebenzisa izinto ezincinci zegazi ezifana ne-aspirin, i-Plavix®, i-Coumadin®, okanye i-heparin
Abantu abanengxaki yezintso (ingakumbi ukuba bakwi-dialysis), ngenxa yokuba banengxaki yokwenza iiseli ezibomvu zegazi Abantu abanengxaki yokufunxa i-iron.
4.Iimpawu zeAnemia
Iimpawu ze-anemia zinokuthambile kangangokuba ungaziqapheli.Ngexesha elithile, njengoko iiseli zakho zegazi ziyancipha, iimpawu zihlala zivela.Ngokuxhomekeke kwisizathu se-anemia, iimpawu zinokubandakanya:
Ukuba nesiyezi, ubuncinci, okanye ukuziva ngathi uza kuphuma ngokukhawuleza okanye ukubetha kwentliziyo okungaqhelekanga
Intloko ebuhlungu Intlungu, kubandakanywa emathanjeni akho, esifubeni, esiswini, nakumalungu Iingxaki zokukhula, kubantwana nabaselula Ukuphelelwa ngumphefumlo Ulusu oluluthuthu okanye olutyheli Izandla ezibandayo neenyawo Ukudinwa okanye ubuthathaka.
Iintlobo ze-5.Anemia kunye nezizathu
Kukho iintlobo ezingaphezu kwama-400 ze-anemia, kwaye zohlulwe ngokwamaqela amathathu:
I-anemia ebangelwa kukulahleka kwegazi
I-anemia ebangelwa kukwehla okanye ukusilela kokuveliswa kweeseli ezibomvu zegazi
I-anemia ebangelwa kukutshatyalaliswa kweeseli ezibomvu zegazi
