Iyini i-hemoglobin(Hgb, Hb)?
I-Hemoglobin(Hgb, Hb) iyiphrotheni emangqamuzaneni abomvu egazi athwala umoya-mpilo usuka emaphashini uwuyise ezicutshini zomzimba wakho bese ubuyisela isikhutha sisuka ezicutshini sibuyele emaphashini akho.
I-Hemoglobin yakhiwe ama-molecule amane amaprotheni (amaketanga e-globulin) axhunywe ndawonye.Iketango ngalinye le-globulin liqukethe i-porphyrin ebalulekile equkethe insimbi ebizwa ngokuthi i-heme.Esakhiweni se-heme kune-athomu yensimbi ebalulekile ekuthutheni umoya-mpilo nesikhutha egazini lethu.I-iron equkethwe ku-hemoglobin nayo ibangela umbala obomvu wegazi.
I-Hemoglobin nayo idlala indima ebalulekile ekugcineni ukuma kwamangqamuzana abomvu egazi.Ngokwesimo sawo semvelo, amangqamuzana egazi abomvu ayindilinga anezikhungo eziwumngcingo ezifana nedonadi elingenayo imbobo phakathi.Ngakho-ke, ukwakheka kwe-hemoglobin engajwayelekile kungaphazamisa ukuma kwamangqamuzana abomvu egazi futhi kuphazamise ukusebenza kwawo futhi kugeleze emithanjeni yegazi.
Kungani kwenziwa
Ungase ube nokuhlolwa kwe-hemoglobin ngezizathu eziningana:
- Ukuhlola impilo yakho iyonke.Udokotela wakho angase ahlole i-hemoglobin yakho njengengxenye yesibalo segazi eliphelele phakathi nokuhlolwa kwezokwelapha okujwayelekile ukuze aqaphe impilo yakho jikelele futhi ahlole izifo ezihlukahlukene, ezifana ne-anemia.
- Ukuxilonga isimo sezempilo.Udokotela wakho angase asikisele ukuhlolwa kwe-hemoglobin uma ubuthakathaka, ukukhathala, ukuphefumula noma isiyezi.Lezi zimpawu nezimpawu zingakhomba ku-anemia noma i-polycythemia vera.Ukuhlolwa kwe-hemoglobin kungasiza ekuhlonzeni lezi noma ezinye izimo zezempilo.
- Ukuqapha isimo sezempilo.Uma kutholwe ukuthi une-anemia noma i-polycythemia vera, udokotela wakho angase asebenzise ukuhlolwa kwe-hemoglobin ukuze aqaphe isimo sakho futhi aqondise ukwelashwa.
Yini izievamileamazinga e-hemoglobin?
Izinga le<em>hemoglobin livezwa njengenani le<em>hemoglobin elingamagremu ( gm ) ngedesilitha ngalinye (dL) legazi lilonke, i<em>deciliter engamamililitha ayikhulu.
Izigaba ezijwayelekile ze-hemoglobin zincike eminyakeni yobudala futhi, kusukela ebusheni, ubulili bomuntu.Ububanzi obujwayelekile yibo:
Wonke lawa manani angahluka kancane phakathi kwama-laboratories.Amanye amalabhorethri awahlukanisi phakathi kwamanani e-hemoglobin “emva kweminyaka emaphakathi” nomuntu omdala.Abesifazane abakhulelwe bayelulekwa ukuba bagweme kokubili amazinga e-hemoglobin aphezulu naphansi ukuze bagweme ukwanda kwezingozi zokubeletha (i-hemoglobin ephezulu - ngaphezu kwesilinganiso esivamile) nokuzalwa ngaphambi kwesikhathi noma ingane enesisindo esiphansi (i-hemoglobin ephansi - ngaphansi kwebanga elijwayelekile).
Uma ukuhlolwa kwe-hemoglobin kuveza ukuthi izinga lakho le-hemoglobin liphansi kunokuvamile, kusho ukuthi unesibalo esiphansi samangqamuzana abomvu egazi (i-anemia).I-anemia ingaba nezimbangela eziningi ezahlukene, kuhlanganise nokuntuleka kwamavithamini, ukopha kanye nezifo ezingapheli.
Uma ukuhlolwa kwe-hemoglobin kukhombisa izinga eliphezulu kunelijwayelekile, kunezimbangela eziningana ezingase zibe khona - ukuphazamiseka kwegazi i-polycythemia vera, ukuhlala endaweni ephakeme, ukubhema kanye nokuphelelwa amandla kwamanzi.
Imiphumela ephansi kunejwayelekile
Uma izinga lakho le-hemoglobin liphansi kunokuvamile, une-anemia.Kunezinhlobo eziningi ze-anemia, ngayinye enezimbangela ezahlukene, ezingabandakanya:
- Ukushoda kwe-ayoni
- Ukushoda kwe-Vitamin B-12
- Ukuntuleka kwe-folate
- Ukopha
- Umdlavuza othinta umnkantsha, njenge-leukemia
- Isifo sezinso
- Isifo sesibindi
- I-Hypothyroidism
- I-Thalassemia - isifo sofuzo esidala amazinga aphansi e-hemoglobin namaseli abomvu egazi
Uma ngaphambilini kutholwe ukuthi une-anemia, izinga le-hemoglobin eliphansi kunokuvamile lingase libonise isidingo sokushintsha uhlelo lwakho lokwelapha.
Iphezulu kunemiphumela evamile
Uma izinga lakho le-hemoglobin liphakeme kunokuvamile, kungase kube umphumela walokhu:
- I-Polycythemia vera - ukuphazamiseka kwegazi lapho umnkantsha wakho wenza amangqamuzana egazi abomvu amaningi kakhulu
- Isifo samaphaphu
- Ukuphelelwa amanzi emzimbeni
- Ukuhlala endaweni ephakeme
- Ukubhema kakhulu
- Ukusha
- Ukuhlanza kakhulu
- Ukuvivinya umzimba ngokweqile
