Yintoni ihemoglobin(Hgb, Hb)?
IHemoglobin(Hgb, Hb) yiprotheyini ekwiiseli ezibomvu zegazi ethwala ioksijini isuka emiphungeni iyise kwizicubu zomzimba wakho ize ibuyisele ikharbon diokside esuka kwizicubu ibuyele emiphungeni yakho.
IHemoglobin yenziwe ziimolekyuli ezine zeprotheyini (itsheyini zeglobulin) ezidityaniswe kunye.Itsheyina 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.
Kutheni yenziwe
Unokuba novavanyo lwe-hemoglobin ngezizathu ezininzi:
- Ukujonga impilo yakho iyonke.Ugqirha wakho unokuvavanya i-hemoglobin yakho njengenxalenye yesibalo esipheleleyo segazi ngexesha lovavanyo lwesiqhelo lonyango ukujonga impilo yakho jikelele kunye nokukhusela izifo ezahlukeneyo, ezifana ne-anemia.
- Ukuxilonga imeko yonyango.Ugqirha wakho unokucebisa uvavanyo lwe-hemoglobin ukuba unobuthathaka, ukudinwa, ukuphefumula okufutshane okanye isiyezi.Ezi mpawu kunye neempawu zingakhomba kwi-anemia okanye i-polycythemia vera.Uvavanyo lwe-hemoglobin lunokunceda ukufumanisa ezi okanye ezinye iimeko zonyango.
- Ukubeka iliso kwimeko yezempilo.Ukuba ufunyaniswe ukuba une-anemia okanye i-polycythemia vera, ugqirha wakho unokusebenzisa uvavanyo lwe-hemoglobin ukujonga imeko yakho kunye nokukhokela unyango.
Zintoni iieqhelekileyoAmanqanaba e-hemoglobin?
Umlinganiselo we<em>hemoglobin uchazwa njengomlinganiselo we<em>hemoglobin kwiigram ( gm ) ngedesilitha ( dL ) nganye yegazi elipheleleyo, i<em>deciliter izimililitha ezili-100.
Uluhlu oluqhelekileyo lwe-hemoglobin luxhomekeke kwiminyaka kwaye, ukuqala ebusheni, isini somntu.Uluhlu oluqhelekileyo lu:
Onke la maxabiso anokwahluka kancinci phakathi kweelabhoratri.Ezinye iilebhu azahluli phakathi kwamaxabiso ehemoglobin “emva kweminyaka ephakathi” nabantu abadala.Abasetyhini abakhulelweyo bayacetyiswa ukuba baphephe zombini amazinga aphezulu kunye ne-hemoglobin ephantsi ukuphepha ingozi eyongeziweyo yokuzala umntwana oshonile (i-hemoglobin ephezulu - ngaphezu koluhlu oluqhelekileyo) kunye nokuzalwa kwangaphambi kwexesha okanye ukuzalwa komntwana onobunzima obuphantsi (i-hemoglobin ephantsi - ngaphantsi koluhlu oluqhelekileyo).
Ukuba uvavanyo lwe-hemoglobin lubonisa ukuba inqanaba lakho le-hemoglobin lingaphantsi kunesiqhelo, oko kuthetha ukuba unenani eliphantsi leeseli ezibomvu zegazi (i-anemia).I-anemia inokuba nezizathu ezininzi ezahlukeneyo, kubandakanywa ukunqongophala kwevithamini, ukopha kunye nezifo ezingapheliyo.
Ukuba uvavanyo lwe-hemoglobin lubonisa inqanaba eliphezulu kunesiqhelo, kukho izinto ezininzi ezinokubangela - i-blood disorder polycythemia vera, ukuhlala kwindawo ephakamileyo, ukutshaya kunye nokuphelelwa ngamanzi emzimbeni.
Iziphumo ezisezantsi kunesiqhelo
Ukuba umgangatho wakho we-hemoglobin ungaphantsi kunesiqhelo, une-anemia.Kukho iintlobo ezininzi ze-anemia, nganye inezizathu ezahlukeneyo, ezinokubandakanya:
- Ukunqongophala kwentsimbi
- Ukunqongophala kwe-Vitamin B-12
- Ukunqongophala kweFolate
- Ukopha
- Umhlaza ochaphazela umongo wethambo, njenge-leukemia
- Isifo sezintso
- Isifo sesibindi
- I-Hypothyroidism
- I-Thalassemia - ingxaki yemfuza eyenza amanqanaba aphantsi e-hemoglobin kunye neeseli ezibomvu zegazi
Ukuba ubukhe wafunyaniswa ukuba une-anemia ngaphambili, inqanaba le-hemoglobin elingaphantsi kuneliqhelekileyo linokubonisa imfuneko yokuguqula isicwangciso sakho sonyango.
Iziphumo eziphezulu kuneziqhelekileyo
Ukuba inqanaba lakho le-hemoglobin liphezulu kunesiqhelo, inokuba sisiphumo soku:
- I-Polycythemia vera - ingxaki yegazi apho umongo wakho wethambo wenza iiseli zegazi ezibomvu ezininzi kakhulu
- Isifo semiphunga
- Ukuphelelwa ngamanzi emzimbeni
- Ukuhlala kwindawo ephezulu
- Ukutshaya kakhulu
- Ukutshisa
- Ukugabha ngokugqithisileyo
- Ukwenza umthambo ngokugqithisileyo
