1.Iyini i-hemoglobin?
I-Hemoglobin (efushanisiwe i-Hgb noma i-Hb) iyi-molecule yephrotheni emangqamuzaneni abomvu egazi athwala umoya-mpilo usuka emaphashini uwuyise ezicutshini zomzimba bese ubuyisela isikhutha sisuka ezicutshini sibuyele emaphashini.
I-Hemoglobin yakhiwe ama-molecule amane amaprotheni (amaketanga e-globulin) axhunywe ndawonye.
Ingqamuzana elivamile le-hemoglobin labadala linamaketanga e-alpha-globulin amabili namaketango amabili e-beta-globulin.
Ezinganeni nasezinsaneni, amaketango e-beta awavamile futhi i-molecule ye-hemoglobin yakhiwe amaketanga e-alpha amabili namaketango amabili e-gamma.
Njengoba usana lukhula, kancane kancane amaketanga e-gamma athathelwa indawo amaketanga e-beta, akhe ukwakheka kwe-hemoglobin yabantu abadala.
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.
2.Ayini amazinga e-hemoglobin ajwayelekile?
Izinga elivamile le- hemoglobin emadodeni liphakathi kuka-14,0 no-17,5 amagremu idesilitha ngalinye (gm/dL);kwabesifazane, kuphakathi kuka-12.3 no-15.3 gm/dL.
Uma isifo noma isimo sithinta ukukhiqizwa komzimba kwamangqamuzana abomvu egazi, amazinga e-hemoglobin angase ehle.Amangqamuzana abomvu egazi ambalwa kanye namazinga e-hemoglobin aphansi angabangela umuntu ukuba ahlaselwe yi-anemia.
3.Ubani okungenzeka kakhulu ukuthi abe ne-anemia yokuntuleka kwe-iron?
Noma ubani angaba ne-iron-deficiency anemia, nakuba amaqembu alandelayo anengozi enkulu:
Abesifazane, ngenxa yokulahlekelwa igazi phakathi nezinyanga kanye nokubeletha
Abantu abangaphezu kweminyaka engama-65, okungenzeka ukuthi badle ukudla okune-iron encane
Abantu abasebenzisa izinto ezinciphisa igazi njenge-aspirin, i-Plavix®, i-Coumadin®, noma i-heparin
Abantu abanenkinga yezinso (ikakhulukazi uma besebenzisa i-dialysis), ngoba banenkinga yokwenza amangqamuzana egazi abomvu Abantu abanenkinga yokumunca i-iron.
4.Izimpawu Zokuntuleka Kwegazi
Izimpawu ze-anemia zingaba mnene kangangokuthi ungase ungaziboni.Esikhathini esithile, njengoba amangqamuzana akho egazi encipha, izimpawu zivame ukuvela.Ngokuya ngembangela ye-anemia, izimpawu zingabandakanya:
Isiyezi, ubumhlophe, noma ukuzwa sengathi usuzophuma ngokushesha noma ukushaya kwenhliziyo okungajwayelekile
Ikhanda elibuhlungu Ubuhlungu, okuhlanganisa emathanjeni akho, esifubeni, esiswini namalunga Izinkinga zokukhula, ezinganeni kanye nentsha Ukuphelelwa umoya Isikhumba esiphaphathekile noma esiphuzi Izandla ezibandayo nezinyawo Ukukhathala noma ubuthakathaka
5.Izinhlobo Nezimbangela Zokuntuleka Kwegazi
Kunezinhlobo ezingaphezu kuka-400 ze-anemia, futhi zihlukaniswe ngamaqembu amathathu:
I-anemia ebangelwa ukulahlekelwa igazi
I-anemia ebangelwa ukwehla noma okungalungile kokukhiqizwa kwamangqamuzana abomvu egazi
I-anemia ebangelwa ukubhujiswa kwamangqamuzana abomvu egazi
