Koj puas tau kuaj ntshav los xyuas koj cov roj cholesterol? Yog tias koj tau kuaj, koj yuav tsum tau pom tias daim ntawv qhia muaj cov lus xws li LDL, HDL, thiab Triglycerides, nrog rau cov ntawv VLDL. Peb feem ntau hnov txog LDL thiab HDL. Lawv kuj hu ua "cholesterol zoo" thiab "cholesterol phem." Tab sis VLDL yog dab tsi? Qhov no yog ib lo lus uas ntau tus neeg tsis paub. Yog li ntawd, yog tias koj tus kws kho mob hais tias koj cov roj VLDL siab hauv koj daim ntawv qhia, nws yog ib txwm muaj kev ntshai me ntsis. Tab sis tsis txhob txhawj. Hnub no, hauv tsab xov xwm no, peb yuav tham txog VLDL yog dab tsi, nws tseem ceeb npaum li cas rau lub cev, thiab nws tuaj yeem cuam tshuam li cas rau peb txoj kev noj qab haus huv yog tias nws nce ntxiv, thiab yuav ua li cas tswj nws.
Hais yooj yim xwb, VLDL yog dab tsi?
Lub ntsiab lus tag nrho ntawm VLDL yog "Very-Low-Density Lipoprotein". Zoo, hnov lub npe no ua rau koj lub taub hau tsis meej pem ntxiv, puas yog? Cia peb rhuav tshem nws yooj yim heev thiab nkag siab nws.
Xav txog peb cov hlab ntsha zoo li txoj kev. Cov kev no nqa ntau yam uas peb lub cev xav tau, xws li cov as-ham thiab oxygen. Lub sijhawm ntawd, cov rog hauv peb lub cev, xws li cov roj cholesterol thiab triglycerides, kuj xav tau kev thauj mus thoob plaws lub cev. Tab sis muaj teeb meem. Cov rog no tsis tuaj yeem ntab hauv cov ntshav ntawm lawv tus kheej, ib yam li thaum koj ntxiv roj rau hauv dej, lawv sib cais es tsis sib xyaw.
Yog li ntawd, peb lub cev muaj ib lub tshuab "tsheb" tshwj xeeb los thauj cov rog no mus thoob plaws lub cev kom muaj kev nyab xeeb. Peb hu cov tsheb no ua "(Lipoprotein)". "Lipo" txhais tau tias rog, "protein" txhais tau tias protein. Qhov ntawd txhais tau tias cov tsheb no yog ua los ntawm cov rog thiab cov protein.
Koj puas nkag siab tam sim no? VLDL yog ib lub tsheb tshwj xeeb heev. Lub tsheb no yog tsim los ntawm peb lub siab thiab tso tawm rau hauv cov ntshav. Lub luag haujlwm tseem ceeb ntawm VLDL yog nqa triglycerides thiab cholesterol los ntawm lub siab mus rau ntau qhov ntawm lub cev, uas yog, mus rau qhov chaw uas xav tau lub zog thiab qhov chaw uas khaws lub zog.
Yog li ntawd, VLDL yog qhov tseem ceeb rau peb lub cev ua haujlwm. Tab sis zoo li txhua yam, ntau dhau ntawm nws tsis zoo rau lub cev.
Lub VLDL particle ua los ntawm dab tsi?
Yog tias peb saib seb muaj dab tsi nyob hauv VLDL uas peb tau tham txog ua ntej, feem ntau nws yog ib hom rog hu ua triglycerides. Ib yam li lub tsheb npav muaj neeg caij ntau. Yog vim li ntawd cov kws kho mob thiaj hu VLDL ua "lipoprotein uas muaj triglyceride ntau."
Tsis tas li ntawd xwb, muaj ob peb yam ntxiv hauv cov khoom VLDL:
- Cov roj cholesterol
- Cov roj fatty acids
- Ib hom protein tshwj xeeb hu ua apolipoprotein B (Apolipoprotein B lossis apoB).
Kev tshawb fawb pom tau tias cov qib siab ntawm cov '(apoB)' no hauv cov ntshav kuj yog ib qho ua rau muaj kev pheej hmoo ntawm kab mob plawv.
VLDL thiab VLDL cholesterol puas yog tib yam?
Txawm hais tias peb feem ntau siv ob lo lus no sib pauv tau los xij, muaj qhov sib txawv me me tab sis tseem ceeb ntawm ob lo lus no.
Xav txog nws li no xwb.
- VLDL yog lub tsheb npav. Nws yog tag nrho lub tsheb uas lub siab ua thiab nqa cov rog.
- Cov roj cholesterol VLDL yog ib qho ntawm cov neeg caij tsheb ntawm lub tsheb npav ntawd. Qhov ntawd yog, qhov ntau ntawm cov roj cholesterol uas mus ncig hauv lub tsheb hu ua VLDL.
Ib yam li ntawd, LDL thiab HDL yog ob hom tsheb sib txawv. Peb hu cov roj cholesterol uas mus rau ntawm lub tsheb npav LDL ua LDL cholesterol. Peb hu cov roj cholesterol uas mus rau ntawm lub tsheb npav HDL ua HDL cholesterol. Tam sim no nws meej lawm, puas yog?
Yog li VLDL puas yog ib hom roj cholesterol "phem"?
Yog, yog tias qib VLDL hauv cov ntshav nce ntau dhau, nws poob rau hauv qeb "phem". Txawm hais tias peb lub cev xav tau qee qhov VLDL kom ua haujlwm tau, thaum nws qib nce ntxiv, nws qhib lub qhov rooj rau kab mob plawv thiab ntau yam teeb meem kev noj qab haus huv.
Qhov teeb meem tseem ceeb yog ib yam mob hu ua '(Atherosclerosis).' Hais yooj yim xwb, qhov no yog thaum cov rog, cov roj cholesterol, thiab lwm yam khoom sib sau ua ke hauv phab ntsa ntawm peb cov hlab ntsha (arteries) thiab tsim ib yam dab tsi hu ua "plaque." Cov plaques no maj mam ua rau cov hlab ntsha nqaim, ib yam li cov av sib sau ua ke hauv cov yeeb nkab dej. Qhov no ua rau cov ntshav ntws tsis zoo.
VLDL muaj feem cuam tshuam li cas rau qhov no?
Xav txog tias peb lub siab pib tsim cov VLDL ntau dua li nws xav tau. Tam sim no muaj cov VLDL nqa ntau dhau hauv cov ntshav. Peb lub cev rhuav tshem cov VLDL ntxiv no thiab siv lawv los ua lwm hom nqa hu ua LDL (Low-Density Lipoprotein). LDL yog hom nqa tseem ceeb uas peb hu ua "cov roj cholesterol phem."
Tam sim no cov ntshav puv nrog cov khoom me me LDL. Cov LDL ntxiv no tau daig rau hauv phab ntsa ntawm cov hlab ntsha, qhov chaw uas nws pib tsim cov plaques uas tau hais ua ntej.
Kev tshawb fawb qhia tau hais tias muaj cov VLDL thiab LDL ntau hauv cov ntshav tib lub sijhawm yog qhov txaus ntshai dua li muaj cov theem siab ntawm ob qho tib si.
Tsis yog li ntawd xwb, thaum VLDL tawg hauv lub cev thiab LDL raug tsim, kuj tseem muaj qee qhov "pieces" uas tshuav ntawm cov txheej txheem ntawd. Cov no hu ua "cov khoom seem." Cov no yog cov khoom me me uas feem ntau muaj cov roj cholesterol. Vim tias lawv me me, lawv yooj yim daig rau hauv phab ntsa ntawm cov hlab ntsha, ua rau cov ntshav txhaws sai dua.
| Cov mob txaus ntshai uas tuaj yeem tshwm sim vim yog atherosclerosis (kev nqaim ntawm cov hlab ntsha) | |
|---|---|
| Mob nkeeg | Piav qhia yooj yim |
| Kab Mob Ntshav Siab | Kev nqaim ntawm cov hlab ntsha uas muab ntshav mus rau lub plawv, uas ua rau muaj kev pheej hmoo ntawm kev mob plawv. |
| Kab Mob Hlwb | Kev nqaim lossis thaiv cov hlab ntsha uas muab ntshav mus rau lub hlwb tuaj yeem ua rau mob stroke. |
| Kab Mob Ntawm Cov Ntshav Qab Zib | Feem ntau, cov leeg ntshav uas xa cov ntshav mus rau ob txhais ceg yuav nqaim. Qhov no tuaj yeem ua rau mob ob txhais ceg thaum taug kev. |
| Kev Kho Mob Aneurysm ntawm Aortic | Lub aorta, uas yog cov hlab ntsha tseem ceeb ntawm lub cev, tsis muaj zog thiab nthuav dav zoo li lub pob. Qhov no tuaj yeem ua rau muaj kev phom sij heev yog tias nws tawg. |
Puas yog LDL txaus ntshai dua? VLDL?
Qhov no yog ib lo lus nug uas ntau tus neeg nug. Qhov tseeb, tsis tuaj yeem hais tias ib qho "phem dua" dua li lwm qhov. Ob qho tib si pab txhawb rau kev tsim cov plaque hauv cov hlab ntsha. Yog li ntawd, ob qho tib si muaj kev phom sij sib npaug. Qhov tseem ceeb yog tswj cov theem ntawm ob qho tib si thiab tswj lawv kom nyob rau theem noj qab haus huv.
Yuav ntsuas cov VLDL li cas? Cov nqi ib txwm muaj yog dab tsi?
Koj cov roj cholesterol VLDL raug ntsuas los ntawm kev kuaj ntshav hu ua lipid panel . Feem ntau qhov kev kuaj no yog ua tom qab koj tau yoo mov li 10-12 teev. Qhov kev kuaj no qhia koj cov roj cholesterol tag nrho, roj cholesterol HDL (zoo), roj cholesterol LDL (phem), thiab roj triglyceride.
Tiam sis ntawm no yog qee yam tshwj xeeb. Feem ntau, cov chaw kuaj mob tsis ntsuas cov VLDL ncaj qha. Hloov chaw, lawv siv koj cov triglycerides los xam koj cov VLDL nrog cov qauv lej.
Hais yooj yim xwb, koj qib VLDL yuav sib npaug li koj qib triglyceride faib rau 5. (Piv txwv li, yog tias koj cov triglycerides yog 150 mg/dL, koj qib VLDL yuav kwv yees li 30 mg/dL).
Txawm li cas los xij, yog tias ib tus neeg cov roj triglyceride siab heev (piv txwv li, tshaj 400 mg / dL), txoj kev suav no yuav tsis raug heev. Hauv cov xwm txheej zoo li no, koj tus kws kho mob yuav siv lwm txoj hauv kev los ntsuas VLDL.
Feem ntau, cov nqi pom zoo rau VLDL cholesterol yog raws li nram no:
- Qib noj qab nyob zoo: Tsawg dua 30 mg/dL (milligrams ib deciliter).
- Muaj kev pheej hmoo/siab: sib npaug lossis ntau dua 30 mg/dL.
Yog tias cov qib VLDL siab dua, peb yuav tsum ua li cas?
Yog koj qib VLDL siab, nws txhais tau tias koj muaj feem yuav mob plawv ntau dua. Tab sis tsis txhob txhawj, qhov no yog ib qho mob uas koj tswj tau.
Thaum kws kho mob kho koj, lawv yuav tsom ntsoov rau kev txo koj cov roj cholesterol LDL thiab triglyceride ntau dua li tsom mus rau cov roj VLDL ncaj qha. Vim tias thaum cov roj no raug tswj, cov roj VLDL yuav raug tswj cia.
Ntau tus neeg uas muaj VLDL ntau yuav muaj ib lossis ntau yam ntawm cov mob no:
- Cov roj triglyceride ntau (Hypertriglyceridemia)
- Cov roj cholesterol LDL siab
- Cov roj cholesterol tag nrho ntau (Hyperlipidemia)
Nov yog qee yam uas koj ua tau los tswj cov rog no. Nws yog ib qho tseem ceeb uas yuav tsum nrog koj tus kws kho mob tham ua ntej pib ua ib qho ntawm cov no.
1. Ua raws li kev noj zaub mov zoo rau lub plawv:
- Txo cov roj, cov khoom noj kib, thiab cov khoom noj kib tob kom ntau li ntau tau.
- Txwv cov khoom noj thiab dej haus uas muaj suab thaj ntau (ncuav mog qab zib, dej qab zib, toffee).
- Ntxiv cov zaub tshiab, txiv hmab txiv ntoo, tshuaj ntsuab, thiab cov nplej tag nrho (buckwheat, barley, oats) rau hauv koj cov zaub mov noj.
- Xaiv ntses thiab nqaij qaib es tsis txhob xaiv nqaij ua tiav lawm.
2. Ua si nawv tsis tu ncua:
- Ua ib qho kev tawm dag zog xws li taug kev sai sai, caij tsheb kauj vab, lossis ua luam dej tsawg kawg 30 feeb hauv ib hnub, tsawg kawg 5 hnub hauv ib lub lim tiam.
- Tseem Ceeb: Yog tias koj tshiab rau kev tawm dag zog, nug koj tus kws kho mob kom tau lus qhia txog kev tawm dag zog twg yog qhov zoo rau koj.
3. Tswj kom muaj qhov hnyav noj qab nyob zoo:
- Nws yog ib qho tseem ceeb heev uas yuav tsum tswj koj qhov hnyav kom zoo rau koj qhov siab. Yog tias koj rog dhau, kev poob phaus tuaj yeem txo koj cov roj cholesterol thiab triglyceride.
4. Noj tshuaj raws li kws kho mob qhia:
- Muaj tej lub sij hawm, kev hloov pauv hauv koj lub neej xwb yuav tsis txaus los tswj koj cov roj cholesterol. Hauv cov xwm txheej zoo li no, koj tus kws kho mob yuav sau ntawv kom koj noj cov tshuaj xws li "statins ." Nws yog ib qho tseem ceeb heev uas yuav tsum noj cov tshuaj uas koj tus kws kho mob tau sau tseg rau hauv qhov ntau npaum li cas thiab rau lub sijhawm kom raug.
Qee zaum, cov triglyceride thiab VLDL theem tuaj yeem nce siab vim yog lwm yam mob xws li ntshav qab zib, teeb meem thyroid, lossis lwm yam tshuaj uas koj noj. Yog li ntawd, yog tias koj muaj lus nug txog cov nqi hauv koj daim ntawv qhia, tham nrog koj tus kws kho mob. Tsis txhob txhawj, nrog kev taw qhia thiab kev kho mob zoo, qhov mob no tuaj yeem tswj tau zoo.
Cov Lus Qhia Txog Kev Coj Mus Tsev
- VLDL yog ib lub tsheb tshwj xeeb uas peb lub siab ua uas feem ntau nqa triglycerides (ib hom rog) thoob plaws lub cev.
- Qib VLDL hauv cov ntshav siab tshaj 30 mg/dL yog qhov tsis zoo rau kev noj qab haus huv ntawm lub plawv. Nws tuaj yeem ua rau cov hlab ntsha nqaim (atherosclerosis).
- Feem ntau cov qib VLDL tsis ntsuas ncaj qha. Lawv suav los ntawm koj cov qib triglyceride.
- Txoj kev zoo tshaj plaws los tswj VLDL yog tswj cov triglyceride thiab LDL (phem) cov roj cholesterol.
- Cov theem VLDL tuaj yeem tswj tau los ntawm kev ua raws li kev noj zaub mov zoo rau lub plawv, kev tawm dag zog tsis tu ncua, tswj qhov hnyav kom noj qab nyob zoo, thiab noj tshuaj raws li koj tus kws kho mob tau hais.
- Yog tias koj muaj lus nug txog koj cov roj cholesterol, nrog koj tus kws kho mob tham.
