VLDL (Very-Low-Density Lipoprotein) nyob rau hauv koj cov roj cholesterol yog dab tsi? Cia peb nrhiav seb nws yog dab tsi!

Tej zaum koj twb tau hnov ​​txog cov roj cholesterol lawm, puas yog? Tej zaum koj twb tau pom lo lus no hauv koj cov ntshav. Tsis muaj dab tsi yuav tsum ntshai thaum koj hnov ​​lo lus roj cholesterol. Txawm li cas los xij, muaj ntau hom sib txawv, thiab nws yog ib qho tseem ceeb kom paub txog lawv. Hnub no peb yuav tham txog ib tug tswv cuab ntawm tsev neeg roj cholesterol, thiab qhov ntawd yog VLDL (Very-Low-Density Lipoprotein) . Lub npe no tej zaum yuav tshiab me ntsis rau koj, tab sis tsis txhob txhawj, cia peb piav qhia yooj yim.

VLDL (Very-Low-Density Lipoprotein), yog dab tsi?

Hais yooj yim xwb, VLDL yog ib hom khoom me me tshwj xeeb uas peb lub siab ua thiab tom qab ntawd tso tawm rau hauv peb cov ntshav. Cov no yog ib pawg ntawm cov protein hu ua lipoproteins .

Xav txog nws, cov rog hauv peb cov ntshav, zoo li cov roj cholesterol thiab triglycerides , tsis txav mus los hauv cov ntshav ntawm lawv tus kheej. Lawv tsis yaj hauv dej. Yog li, cov rog no xav tau lub tsheb thauj lawv mus rau ntau qhov ntawm lub cev. Lub tsheb ntawd hu ua lipoproteins. Nws zoo li lub tsheb npav!

Lub luag haujlwm tseem ceeb ntawm VLDL yog coj cov triglycerides thiab qee cov roj cholesterol thiab thauj lawv mus rau qhov chaw uas lawv xav tau hauv lub cev. Ua li no, VLDL pab peb lub cev kom tau txais lub zog, khaws cia lub zog, thiab tswj cov ntshav siab. Yog li, lawv tseem ceeb heev rau kev ua haujlwm ib txwm ntawm peb lub cev.

Txawm li cas los xij, ntawm no yog qee yam uas yuav tsum nco ntsoov: Yog tias VLDL ntau dhau hauv cov ntshav, nws tuaj yeem ua rau muaj kev phom sij. Yog tias qhov ntawd tshwm sim, qhov kev pheej hmoo ntawm kev mob plawv yuav nce ntxiv.

Muaj dab tsi nyob hauv cov khoom VLDL no?

Ib feem ntawm cov VLDL feem ntau yog ua los ntawm ib hom rog hu ua triglycerides . Nws kuj muaj cov roj cholesterol , cov roj fatty acids, thiab ib hom protein tshwj xeeb hu ua apolipoprotein B (apoB) . Kev tshawb fawb tau pom tias cov theem siab ntawm apoB no hauv cov ntshav yog txuam nrog kev pheej hmoo ntawm kab mob plawv.

Qhov tseeb, txhua yam lipoproteins yog ua los ntawm cov rog thiab cov protein. Txawm li cas los xij, qhov ntau thiab hom ntawm cov rog thiab cov protein no sib txawv ntawm ib qho lipoprotein mus rau lwm qhov. Vim tias VLDLs muaj ntau triglycerides , cov kws kho mob qee zaum hu lawv ua "triglyceride-rich lipoproteins."

VLDL thiab VLDL cholesterol puas yog ob yam sib txawv?

Qhov no yuav zoo li ua rau neeg tsis meej pem me ntsis, tab sis nws yooj yim to taub. Feem ntau, cov lus "VLDL" thiab "VLDL cholesterol" siv sib pauv tau. Txawm li cas los xij, muaj qhov sib txawv me ntsis ntawm ob qho no uas tseem ceeb heev uas yuav tsum paub.

• VLDL yog hais txog cov lipoprotein me me uas peb tau hais ua ntej. Qhov ntawd yog, lub "tsheb" lossis "npav" uas lub siab ua thiab nqa cov rog thiab cov protein hauv cov ntshav.
• Cov roj cholesterol VLDL yog hais txog cov neeg caij cov roj cholesterol ntawm lub tsheb npav VLDL. Uas yog, qhov ntau ntawm cov roj cholesterol uas thauj mus thoob plaws cov ntshav los ntawm cov khoom me me VLDL.

Lwm hom lipoproteins, xws li LDL (Low-Density Lipoproteins) thiab HDL (High-Density Lipoproteins) , zoo ib yam li lwm hom roj cholesterol no. Txhua hom muaj ntau hom rog thiab protein sib txawv. Yog vim li ntawd peb thiaj tham txog LDL cholesterol thiab HDL cholesterol.

Yog li VLDL puas yog ib hom roj cholesterol "phem"?

Yog lawm, hauv luv luv, yog tias cov roj cholesterol VLDL hauv cov ntshav siab dua li qhov tsim nyog, nws tuaj yeem hais tias "phem". Peb lub cev xav tau qee qhov VLDL rau nws cov kev xav tau. Txawm li cas los xij, yog tias qib ntawm VLDL nce ntxiv, nws ua rau muaj kev pheej hmoo ntawm atherosclerosis , uas yog, kev tsim cov rog (plaque) hauv cov hlab ntsha (arteries). Qhov no yog lub hauv paus ua rau ntau yam kab mob plawv.

VLDL pab txhawb rau atherosclerosis li cas?

Thaum peb lub siab tsim cov VLDL ntau dua li peb lub cev xav tau, lub cev zom cov VLDL ntxiv. Ua li no, VLDL raug hloov ua ntej mus ua IDL (Intermediate-Density Lipoproteins) thiab tom qab ntawd LDL (Low-Density Lipoproteins) . Cov IDL thiab LDL no yog cov hom lipoproteins uas lub cev xav tau.

Tiam sis, qhov teeb meem yog, yog tias LDL no ntau dua li lub cev xav tau, nws tuaj yeem sib sau ua ke. Thaum muaj LDL ntau dhau hauv cov ntshav, nws tuaj yeem daig rau hauv phab ntsa ntawm cov hlab ntsha, qhov chaw uas cov rog pib tsim. Thaum cov rog no maj mam loj hlob, lawv ua rau cov hlab ntsha nqaim thiab cuam tshuam cov ntshav ntws.

Kev tshawb fawb pom tau tias kev nce ntxiv ntawm VLDL nrog rau kev nce ntxiv ntawm LDL yog qhov txaus ntshai dua li kev nce ntxiv ntawm ib leeg.

Tsis yog li ntawd xwb, thaum VLDL tawg thiab LDL tsim, qee cov " cov khoom seem" tseem tshuav nyob hauv cov ntshav. Cov khoom seem no kuj muaj ntau cov roj cholesterol. Vim tias lawv me me, lawv tuaj yeem yooj yim daig rau hauv cov phab ntsa ntawm cov hlab ntsha thiab ua rau muaj atherosclerosis (Nws accelerates tus txheej txheem ntawm atherosclerosis.

Kab mob Atherosclerosis yog ib qho mob txaus ntshai vim nws ua rau koj cov hlab ntsha nqaim, ua rau koj muaj feem yuav muaj ntau yam kab mob plawv. Nov yog ob peb yam piv txwv:

• Kab mob plawv ( kab mob ntawm cov hlab ntsha uas muab ntshav mus rau lub plawv)
• Kab mob cerebrovascular ( cov kab mob hauv cov hlab ntsha uas muab ntshav mus rau lub hlwb, uas tuaj yeem ua rau muaj mob xws li mob stroke)
• Kab mob ntawm cov hlab ntsha peripheral ( cov kab mob ntawm cov leeg uas muab ntshav rau caj npab thiab ceg)
• Aortic aneurysm (kev qaug zog thiab o ntawm lub aorta, lub cev cov hlab ntsha tseem ceeb)

Qhov twg phem dua, LDL lossis VLDL?

Qhov tseeb, ob qho tib si LDL cholesterol thiab VLDL cholesterol pab txhawb rau kev sib sau ua ke ntawm cov rog hauv peb cov hlab ntsha. Yog li, nws nyuaj rau hais tias ib qho tshwj xeeb "phem dua" dua li lwm qhov. Ob qho tib si yog atherogenic sib npaug, txhais tau tias lawv pab txhawb rau cov txheej txheem ntawm cov rog hauv cov hlab ntsha. Yog li nws yog ib qho tseem ceeb kom paub txog ob qho tib si.

Yuav ntsuas cov roj cholesterol VLDL li cas?

Cov kws kho mob ntsuas koj cov roj cholesterol VLDL los ntawm kev kuaj ntshav hu ua lipid panel . Qhov no yog kev kuaj ntshav uas siv ntau heev.

Daim lipid panel no qhia txog tag nrho cov roj cholesterol hauv koj cov ntshav. Tsis yog li ntawd xwb, nws kuj qhia txog cov roj cholesterol sib txawv hu ua HDL (cov roj cholesterol zoo), LDL (cov roj cholesterol phem), thiab VLDL sib cais. Tsis tas li ntawd, qhov kev kuaj no tuaj yeem qhia koj txog cov roj triglycerides hauv koj cov ntshav. Nco ntsoov, peb tau hais tias VLDL muaj cov roj triglycerides ntau tshaj plaws.

Feem ntau, cov chaw kuaj mob tsis ntsuas koj cov VLDL ncaj qha. Hloov chaw, lawv siv koj cov triglycerides los xam koj cov VLDL nrog cov qauv lej. Feem ntau, koj cov triglycerides yog li tsib npaug ntawm koj cov VLDL.

Txawm li cas los xij, yog tias koj muaj mob hnyav hu ua hypertriglyceridemia , uas yog thaum koj cov triglyceride siab heev, qhov kev suav lej ntawd yuav tsis raug. Yog li ntawd, koj tus kws kho mob yuav siv lwm txoj hauv kev los kwv yees koj cov VLDL.

Tus nqi roj cholesterol VLDL ib txwm muaj yog dab tsi?

Qib ib txwm muaj, lossis noj qab nyob zoo, rau VLDL yog tsawg dua 30 milligrams ib deciliter ntawm cov ntshav ( < 30 mg/dL ). Yog tias koj cov roj cholesterol VLDL yog 30 mg/dL lossis siab dua , nws suav tias siab.

Yuav ua li cas yog tias VLDL cholesterol nce siab?

Qhov tseem ceeb yog tias cov roj cholesterol VLDL siab ua rau muaj kev pheej hmoo ntawm kab mob plawv .

Txawm li cas los xij, vim tias cov qib VLDL raug suav los ntawm kev siv cov qauv lej es tsis yog ntsuas ncaj qha, thiab vim tias VLDL tsis yog lub hom phiaj tseem ceeb rau cov kws kho mob thaum kho koj, koj tus kws kho mob yuav tsis tham nrog koj txog koj qib VLDL. Hloov chaw, nws yuav tsom mus rau lwm yam nqi, xws li koj qib LDL thiab triglycerides , vim tias cov no yog cov nqi uas tau tsom mus rau kev kho mob.

Ntau tus neeg uas muaj cov roj cholesterol VLDL siab kuj tseem yuav muaj ib lossis ntau yam mob hauv qab no tib lub sijhawm:

• Cov roj triglyceride ntau ntxiv (Hypertriglyceridemia)
• Cov roj cholesterol LDL ntau ntxiv
• Cov roj cholesterol tag nrho nce ntxiv (Hyperlipidemia)

Qhov xov xwm zoo yog, muaj ntau yam koj ua tau los txo cov rog no (lipids) hauv koj cov ntshav:

• Ua raws li kev noj zaub mov zoo rau lub plawv , xws li kev noj zaub mov Mediterranean , uas tsom mus rau zaub, txiv hmab txiv ntoo, taum pauv, cov nplej tag nrho, ntses, thiab cov rog zoo li roj txiv roj.
• Ua si nawv tsis tu ncua . Txawm li cas los xij, nws yog ib qho tseem ceeb heev uas yuav tsum nrog koj tus kws kho mob tham thiab tau txais lus qhia ua ntej koj pib ua ib qho kev tawm dag zog tshiab.
