Ikhalori yecholesterol: yazi ukuba icholesterol yakho ilungile

Umxholo

• Ibalwa njani i-cholesterol?
• Yintoni icholesterol?
• Zithini iintlobo?
• Ngaba ukuba ne-cholesterol ephezulu kusoloko kukubi?

Ukwazi ukuba ngawaphi amanqanaba e-cholesterol kunye ne-triglycerides ejikeleza egazini kubalulekile ukuvavanya impilo yentliziyo, kungenxa yokuba kwiimeko ezininzi apho utshintsho luqinisekisiweyo kunokubakho umngcipheko omkhulu wokukhula kwezifo ezinxulumene nentliziyo, ezifana ne-infarction kunye ne-atherosclerosis, umzekelo.

Chwetheza ikhalityhuleyitha engezantsi kwamaxabiso e-cholesterol avela kuvavanyo lwakho lwegazi kwaye ubone ukuba icholesterol yakho ilungile na:

I-Vldl / i-Triglycerides ibalwe ngokomgaqo we-Friedewald

Ibalwa njani i-cholesterol?

Ngokubanzi, xa kusenziwa uvavanyo lwegazi ukuvavanya iprofayili ye-lipid, kubonisiwe kwisiphumo sokuba ixabiso le-cholesterol lifunyenwe ngeendlela ezithile zaselebhu. Nangona kunjalo, kwezinye iimeko ayingawo onke amaxabiso akhutshwayo kuvavanyo afunyenwe kusetyenziswa ubuchwephesha belebhu, kodwa kwabalwa kusetyenziswa le fomyula ilandelayo: iyonke icholesterol = HDL cholesterol + engeyo-HDL cholesterol, apho non-HDL ukuya kwi-LDL + VLDL.

Ukongeza, xa amaxabiso eVLDL engafumaneki, kunokwenzeka ukubala usebenzisa ifomula kaFriedewald, ethathela ingqalelo amaxabiso e-triglyceride. Ke, ngokomgaqo weFriedewald, VLDL = triglyceride / 5. Nangona kunjalo, ayizizo zonke iilebhu ezisebenzisa le fomyula, kwaye iziphumo ziyahluka.

Yintoni icholesterol?

Ikholesterol luhlobo lwamafutha akhoyo emzimbeni kwaye lubalulekile ekusebenzeni kakuhle komzimba, kuba kubalulekile kwinkqubo yokuvelisa iihomoni, ivithamin D kunye nenyongo, into egcinwe kwinyongo kwaye inceda yokwetyisa amafutha. Ukongeza, icholesterol ikwayinxalenye yeseli kwaye ibalulekile kwimetabolism yeevithamini ezithile, ngakumbi iivithamini A, D, E kunye noK.

Zithini iintlobo?

Ngokweempawu zayo, icholesterol inokuhlelwa ngokweendidi ezintathu:

• I-cholesterol ye-HDL, eyaziwa ngokuba yi-cholesterol elungileyo, iveliswa ngumzimba kwaye inoxanduva lokukhusela intliziyo kwaye, ke ngoko, kubalulekile ukuba amanqanaba ayo ahlala ephezulu;
• I-cholesterol ye-LDL, ekwabizwa ngokuba yi-cholesterol embi, kulula ukubekwa eludongeni lwemithambo, kuthintela ukuhamba kwegazi kunye nokwandisa umngcipheko wesifo sentliziyo;
• I-cholesterol ye-VLDL, elijongene nokuthuthwa kwe-triglycerides emzimbeni.

Kuviwo, kubalulekile ukuba unikele ingqalelo kuwo onke la maxabiso nakwiziphumo ze-cholesterol iyonke kunye nenqanaba le-triglyceride, ukuze kube nakho ukwazi ukuba ngaba lukhona na utshintsho nokuba kunyanzelekile ukuba luqale uhlobo oluthile unyango. Funda kabanzi malunga neentlobo ze-cholesterol.

Ngaba ukuba ne-cholesterol ephezulu kusoloko kukubi?

Kuxhomekeka kuhlobo lwecholesterol enyukayo. Kwimeko ye-HDL, kubalulekile ukuba amaxabiso ahlala ephezulu, kuba le cholesterol ibalulekile ukugcina impilo yentliziyo, kuba isebenza ngokususa iimolekyuli ezinamafutha ezinokuqokelelana egazini kwaye zifakwe kwimithambo.

Kwelinye icala, xa kufikwa kwi-LDL, kuyacetyiswa ukuba le cholesterol ingabikho egazini, kuba lolu hlobo lwecholesterol olufakwa ngokulula kwimithambo, olunokukhokelela ekwakhiweni kwamacwecwe kwaye kuphazamisane ukuhamba kwegazi, okwandisa umngcipheko wesifo senhliziyo, njenge-atherosclerosis kunye nokuhlaselwa kwentliziyo, umzekelo.
