Fasting vs Nonfasting Cholesterol
Kev ntsuas cov roj cholesterol yog ib qho kev kuaj ntshav tshaj plaws. Mob ntshav qab zib, mob plawv, mob stroke thiab hlab ntsha nqaim tau nce ntxiv, thiab Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv (World He alth Organization) tau pom zoo cov roj cholesterol hauv cov ntshav raws li ib qho ntawm cov cuab yeej tshuaj ntsuam uas siv los txiav txim qhov kev pheej hmoo ntawm kev mob plawv ischemic. Sib nrug ntawm qhov no, vim li cas siv tau ntau tus neeg tau kuaj xyuas lawv cov roj (cholesterol) ntau zaus kom lawv tswj tau nrog kev noj zaub mov thiab tshuaj raws li xav tau. Cov kev ntsuam xyuas no tseem ceeb heev rau cov tib neeg noj qab nyob zoo thiab cov neeg mob plawv. Nws yog ib txwm tsim nyog kom paub qhov txawv me ntsis ntawm ob qhov kev xeem.
Kev yoo mov thiab tsis yoo mov cov roj cholesterol yog nyob ntawm cov metabolism hauv lub cev, tshwj xeeb tshaj yog cov roj cholesterol metabolism. Peb cov khoom noj muaj cov roj cholesterol thiab fatty acids. Cov rog rog tau emulsified thiab tawg hauv cov hnyuv. Cov rog ua rau cov rog rog, glycerol thiab cov roj cholesterol. Cov roj (cholesterol) yog cov rog soluble, yog li nws nkag mus rau hauv cov kab mob hauv cov hnyuv ncaj qha. Hauv cov hlwb, cov roj cholesterol thiab fatty acids tau compacted rau hauv chylomicrons. Raws li chylomicrons, cov roj cholesterol tau thauj mus rau hauv cov hlab ntsha thiab tom qab ntawd mus rau hauv daim siab. Lub siab siv cov roj cholesterol hauv chylomicrons. Lub siab kuj tseem tsim cov roj cholesterol siv cov enzyme hu ua HMGCoA reductase, uas ua haujlwm heev thaum hmo ntuj. Yog li ntawd, cov kws kho mob tau sau tshuaj statins (HMGCoA reductase inhibitors) thaum hmo ntuj. Lub siab tsim cov lipoproteins tsawg heev (LDL) uas muaj ntau cov fatty acids thiab glycerol. Ntawm cov hlab ntsha hauv lub cev kawg, cov lipoproteins tsawg ntom ntom tau tawg ib feem, thiab qee cov fatty acids thiab glycerol tau nqus. Qhov tshwm sim yog nruab nrab ntom ntom lipoproteins. Thaum kawg ntawm lub cev, cov hlwb tsim cov cholesterol. Cov roj (cholesterol) no tau pauv mus rau qhov nruab nrab ntom ntom lipoproteins uas tsim cov lipoproteins siab ntom ntom (HDL). Cov no ua rau cov roj cholesterol rov qab mus rau lub siab kom rov ua haujlwm dua. Lub siab yog lub hub uas coj tag nrho cov hluavtaws thiab catabolic txoj hauv kev ua ke. Kev yoo mov yog qhov hloov pauv tseem ceeb ntawm txhua txoj hauv kev no. Kev yoo mov siv tag nrho cov piam thaj uas yooj yim los ntawm daim siab hauv feeb. Tom qab ntawd glycogen tawg pib. Tom qab li ib nrab teev, rog rog pib. Cov enzymes uas tawg ua kom ntom heev lipoproteins tau txiav tawm thiab cov tshuaj hormone rhiab li hauv cov roj hlwb tau qhib. Yog li ntawd, tawg rog mus rau daim siab ua substrates rau gluconeogenesis; tseem hu ua synthesis of new glucose.
Kev ntsuas ceev cov roj cholesterol, lossis kom meej meej, ceev lipid profile, ntsuas cov kab catabolic thiab anabolic. Kev kuaj ntshav cholesterol yuav tsum tau yoo mov 12 teev. Kev yoo mov zoo li nce qib ntawm cov lipoproteins tsawg heev (VLDL), qis lipoproteins tsawg, thiab qis qis lipoproteins tsawg. Yog tias lub cev muaj peev xwm ua kom cov roj metabolism zoo, cov qib no yuav tsum tswj hwm. Qhov kev pheej hmoo ntawm qib siab ntawm cov lipoproteins tsawg ntom ntom yog tias nws nce qhov tshwm sim ntawm arterial hardening thiab atheromatous plaque tsim. Kev yoo mov yog ib txoj hauv kev siv los ntsuas cov txheej txheem sab hauv. Txawm li cas los xij, kev tshawb fawb tsis ntev los no hais tias kev yoo mov tsis yog qhov tseem ceeb. Nws tsis ua rau muaj qhov sib txawv loj hauv cov ntshav qabzib. Feem ntau, tag nrho cov roj (cholesterol) yuav tsum tsawg dua 200mg / dl. LDL yuav tsum qis dua 100 mg / dl thiab HDL yuav tsum siab dua 50 mg / dl.
Y Tsis yoo mov cov roj (cholesterol)
Tsis yoo mov ntshav cov roj cholesterol yog ib qho yooj yim ua. Ntau yam kab mob thiab kev noj haus hloov cov roj cholesterol. Nws yog ib qho nyuaj rau muab cov kab txiav tawm rau ib tus neeg cov khoom ntawm cov tsis yoo mov lipid profile vim muaj kev hloov pauv hauv cov metabolism ntawm ib tus neeg mus rau lwm tus. Feem ntau, tag nrho cov roj (cholesterol) tsis yoo mov yuav tsum qis dua 200 mg / dl. Tus nqi no zoo ib yam li kev yoo mov tag nrho cov roj cholesterol vim tias kev yoo mov tiag tiag tsis muaj feem cuam tshuam rau tag nrho cov lipid qib. Raws li kev tshawb fawb tsis ntev los no, kev yoo mov tsis yog qhov tseem ceeb thiab tsis muaj qhov hloov pauv tseem ceeb ntawm cov roj cholesterol tsis yoo mov. Yog li ntawd, ceev lipid profile yog qhov kev ntsuam xyuas pom zoo. Kev ntsuas tsis yoo mov feem ntau muab tag nrho cov qib lipid thiab tsis yog tag nrho cov profile.
Dab tsi yog qhov txawv ntawm Kev yoo mov thiab tsis noj cov roj (cholesterol)?
• Kev yoo mov lipid profile ntsuas cov txheej txheem metabolic kom raug thaum tsis yoo lipid profile tsis ua, vim muaj kev hloov pauv hauv metabolic.
• Lipid profile xav tau kev yoo mov thiab muab qhov tseem ceeb rau txhua tus neeg ntawm cov roj metabolism hauv txoj hauv kev thaum tsis yoo mov cov roj cholesterol ntsuas tag nrho cov lipid qib nkaus xwb.
