Mulingo wa cholesterol wa LDL ndi gawo lomwe limayesedwa panthawi ya lipid. Udindo wonyamula mafuta m'thupi m'thupi, LDL cholesterol ndi lipoprotein yotchedwa "cholesterol yoyipa" chifukwa kuchuluka kwake kumapangitsa chiwopsezo chamtima.

Kodi LDL cholesterol ndi chiyani?

LDL cholesterol, yomwe nthawi zina imalembedwa LDL-cholesterol, ndi lipoprotein yotsika kwambiri yomwe imathandiza kunyamula mafuta m'thupi lonse. Ngakhale idatsutsidwa kwambiri m'zaka zaposachedwa, cholesterol ndi gawo lofunikira kuti thupi lizigwira ntchito moyenera. Lipid iyi imatenga nawo gawo pamapangidwe a nembanemba zama cell, pakuphatikizika kwa mamolekyu ambiri komanso kupanga mchere wa bile wofunikira pakugayitsa lipids. Potenga nawo gawo pakugawa kolesterol m'magulu osiyanasiyana, cholesterol ya LDL imagwira ntchito yofunika kwambiri m'thupi.

Chifukwa chiyani amatchedwa "cholesterol yoyipa"?

Ngakhale kuti LDL cholesterol ndi imodzi mwa zonyamulira cholesterol m'thupi, pali ena kuphatikiza HDL cholesterol. Wotsirizirayo amatha kutenga cholesterol yochulukirapo m'thupi ndiyeno kupita nayo kuchiwindi kuti ichotsedwe. Kuyendera kwa HDL cholesterol ndikofunikira kwambiri chifukwa cholesterol yochulukirapo m'magazi ndizomwe zimayambitsa chiopsezo cha mtima. Ichi ndichifukwa chake cholesterol ya HDL imatchedwa "cholesterol yabwino" pomwe LDL cholesterol imatchedwa "cholesterol yoyipa".

Kodi zabwinobwino za LDL cholesterol ndi ziti?

Mulingo wa cholesterol wa LDL nthawi zambiri umawonedwa ngati wabwinobwino ukakhala pakati pa 0,9 ndi 1,6 g / L mwa akulu.

Komabe, izi zitha kusiyanasiyana kutengera ma labotale owunikira zamankhwala komanso magawo ambiri kuphatikiza jenda, zaka komanso mbiri yachipatala. Kuti mudziwe zambiri, muyenera kufunsa dokotala.

Mulingo wa cholesterol wa LDL m'magazi ndi chimodzi mwazinthu zomwe zimayesedwa kuti aunike kuchuluka kwa cholesterol yonse m'thupi.

Kutanthauzira kwa mulingo wa cholesterol wa LDL kumagwiritsidwa ntchito popewa, kuzindikira komanso kuyang'anira ma dyslipidemias awiri:

• hypocholesterolemia, yomwe imafanana ndi kuchepa kwa cholesterol;
• hypercholesterolemia, omwe amatanthauza cholesterol yochulukirapo.

Kutsimikiza kwa LDL cholesterol kumachitika ndi labotale yowunikira zamankhwala. Pamafunika kuyezetsa magazi, komwe nthawi zambiri kumachitika chapakati pa chigongono.

Kenako magaziwo amagwiritsidwa ntchito popanga mbiri ya lipid. Chomalizachi chimakhala ndi kuyeza milingo yamagazi amitundu yosiyanasiyana ya lipids kuphatikiza:

• LDL cholesterol;
• HDL cholesterol;
• triglycerides.

Mulingo wa cholesterol wa LDL ndi mtengo womwe umasiyanasiyana malinga ndi kuchuluka kwa lipid. Pachifukwa ichi, kuyezetsa magazi kuyenera kutengedwa pamimba yopanda kanthu, ndipo makamaka kwa maola 12. Ndikulimbikitsidwanso kuti musamwe mowa maola 48 musanayambe kuyesa lipid.

Kutanthauzira kwa milingo ya LDL cholesterol kumathandizira kusanthula kolesterol. Komabe, izi ziyenera kuwerengedwa potengera zomwe zimapezedwa pamlingo wa lipid. Zotsirizirazi zimawonedwa ngati zabwinobwino ngati:

• okwana mafuta msinkhu ndi zosakwana 2 g / L;
• LDL cholesterol ndi yochepera 1,6 g / L;
• Mulingo wama cholesterol wa HDL ndioposa 0,4 g / L;
• mulingo wa triglyceride ndi wochepera 1,5 g / L.

Makhalidwe awa amaperekedwa kuti mudziwe zambiri. Zitha kusiyanasiyana malinga ndi magawo osiyanasiyana kuphatikiza jenda, zaka komanso mbiri yachipatala. Ndikofunikira kuti mulankhule ndi dokotala kuti amasulire zotsatira za kuwunika kwa lipid.

Kutanthauzira kwa cholesterol yotsika ya LDL

Kutsika kwa LDL cholesterol, kuchepera 0,9 g / L, kungakhale chizindikiro cha hypocholesterolemia, ndiye kuti kuchepa kwa cholesterol. Komabe, chodabwitsa ichi ndi chosowa. Ikhoza kugwirizanitsidwa ndi:

• chibadwa chachilendo;
• kusowa zakudya m'thupi;
• cholesterol malabsorption;
• matenda monga khansa;
• mkhalidwe wokhumudwitsa.

Kutanthauzira kwa cholesterol yayikulu ya LDL

Kukwera kwambiri kwa cholesterol ya LDL, yoposa 1,6 g / L, iyenera kutanthauziridwa ngati chizindikiro chochenjeza. Ichi ndi chizindikiro cha hypercholesterolemia, ndiko kunena za cholesterol yambiri m'magazi. Thupi silingathenso kuwongolera kuchuluka kwa cholesterol yonse, zomwe zimapangitsa kuti lipids aziwunjika m'mitsempha. Kuyika kwamafuta pang'onopang'ono kungayambitse mapangidwe a atheromatous plaque, zotsatira zake pa thanzi zomwe zingakhale zovuta. Kuthamanga kwa magazi kumasokonekera, zomwe zimawonjezera chiopsezo cha kuthamanga kwa magazi. Kuphulika kwa atheromatous plaque kungakhalenso chifukwa cha myocardial infarction, stroke, kapena arteritis obliterans ya m'munsi (PADI).
