Akamaro k'Ibinure vyo mumubiri wacu
Ibinure bifise akamaro kanini mumubiri wacu kandi tutabifise ubuzima bwacu bwohura n'ibibazo bikomeye nko kudufasha kuringaniza ubushuhe bubereye mumubiri wacu ( régulation thermique ) no gutuma inkaburamubiri ( hormones) nyinshi zihingurwa.

Ico bita ikinure co mu maraso ( cholestérol sanguin ) nico ahanini tugiye kuganirako,ico gihingurwa n'igitigu ( foie) hamwe n'urura ( Intestin), kigatemberezwa mumaraso n'ibitwazi ( Transporteurs). Ivyo bitwazi canke izo transporteur bita lipoprotéines. Lipoprotéines ni ni indemamubiri zivanganye n'ibinure zikaba arizo zijejwe gutwara cholestérol mu maraso.
Ubwoko bwa Lipoprotéines
Izo lipoprotéines zikora nkibitwazi ziri mu mirwi bibiri:
1. Lipoprotéine à basse densité:
Izi Lipoprotéines zifise ubukana buke, nikuvuga ko zifise ubushobozi buke
2. Lipoprotéine densité élevée:
Izo Lipoprotéine zifise ubukana bwinshi cane mubuzima bwabantu
Igikorwa ca buri Lipoprotéine
1.Lipoprotéine y'ubukana buke :Lipoprotéine à basse densité
Iyi bayita LDL akaba ari impfunyapfunyo y'amajambo y'icongereza, mu majambo yose ni Low Density Lipoprotein.
Itembereza cholestérol iyikura mu gitigu iyijana mumisokoro itandukanye ( tissus).Maze ino cholestérol ikaca ija kwihomeka ku mitsi indani ( paroi artérielle ).
Iyo ingorane yo kwihomeka ku mitsi iteza indwara nyinshi zishingiye ku mitsi n'umutima ( maladies cardio-vasculaires) ibi turabigarukako mu buryo bwagutse. Niyo mpamvu LDL bayita ikinure kibi ( mauvais cholestérol).
2. Lipoprotéine y'ubukana bwinshi : Lipoprotéine à densité élevée
Iyi nayo bayita HDL ni impfunyapfunyo c'icongereza High Density Lipoprotein.
Iyi yo ikora ikinyurane c'iyambere kuko ikura cholestérol mu misokoro no mu misoso ikayizana mu gitigu kugira ngo yongere ihingurwe. Muri make ikora nk'imikubuzo ikubura ya cholestérol mbi yihometse ku mitsi n'iyirundanije mumisoso ikayisubiza mu gitigu. Nico gituma bayita ikinure ciza (Bon cholestérol).
Iyo umuntu amaze kugira cholestérol irenga 2g/l baca bavuga ko yagize hypercholestérolémie.
Hypercholestérolémie ni ingorane yo muhingurwa ry'ibinure mu mubiri ( métabolisme lipidique) bitewe n'iduga rya cholestérol mu maraso. Akenshi hypercholestérolémie ni ijanirana n'iduga ry'ikinure ca triglycérides mu maraso.
Triglycérides ni ibinure bitembera mu maraso vyavuye mu masukari umuntu yihereje. Urugero rubereye rwa triglycérides ni ≈ 1,5 mmol/l.
Ibitera umurengera wa Cholestérol
Ibinure bigumye ( Acides gras saturé ) ibi bikaba birwiriye mu:
Abantu bakunda kwiheza ivyo tuvuze cane bafise amahirwe menshi yokugira ibinure vyinshi.
Ibitera ibinure vya Triglycérides
Ingaruka mbi z'ivyo binure bibi
Ibi binure bibi biteza indwara nyinshi cane mbi zitinyitse kandi zica:
Ivuduka rirenze y'umurindi w'amaraso : Hypertension artérielle
Benshi mu barwaye iyi ndwara bayitewe n'ikikinure kibi. Iyo kimaze gushika mu maraso twabonye ko cholestérol ica ija kwihomeka ku mitsi itembereza amaraso bita artères, maze ku mitsi hakihomekako ibintu vy'ibikoko nkabirya vy'inkono yacumbwemwo ubugari ivyo bikoko vy'ibinure bavyita plaque atheromateuse canke atherome. Kuri uyo mutsi vyihometseko uca ukomarara maze amaraso ntabe akirengana ico gihe bisaba ko umutima uterana inguvu ibi nivyo birwaza indwara y'ivuduka rirenze ry'umurindi w'amaraso.
Amasanganya y'imitsi yo mu bwonko : Accidents vasculaires cérébraux AVC
Iyi nayo iterwa nuko vyabinure bitembera mu maraso iyo biramutse biduze mu bwonko bikagira umutsi runaka wo mwubwonko twugara nanyaburya ari dutoduto, ico gihe icokibaza cavomerwa n'uwomutsi inyuma y'iminota 4 amaraso atakijayo kica cononekara ( nécrose ) maze niharya muca mubona umuntu igihimba kimwe kiba paralysé.
Ibora ry'inyama z'umutima: Infactus de myocarde
Iyo bishitse ca kinure kikaja mu nyama zo mu umutima naho nyene hari imitsi mitomito bita nerfs coronaires, iyo bishitse kikugara imitsi ico gihe umutima uca ubura amaraso awuvomera maze ico gice kica kibora. Ico gihe ni hamwe umuntu atangura kumva udusonga dutera iyo aduze nk'umusozi canke yirutse uyo musonga wo mu mutima bawita angine de poitrine.
MN: Izo ni indwara utomeya kiretse zigira ziguhitane
Inkuru nziza kuwahuye nivyo bibazo
Kwihereza cane ibimera bigizwe n'ivyamwa no kugabanya inyama z'ibikoko bizogufasha.
Ubushakashatsi muvy 'amagara , buramaze gushika kuntambwe nziza aho ico kibazo gikemuka mukanya isase.
Turafise imiti ihinguwe mubimera kubuhinga bwa none ituma umubiri ubwawo wirukana ibinure bidakenewe maze umuntu akagira amagara meza.
