LDL and HDL Cholesterol: "Bad" and "Good" Cholesterol: Lowering Your Risk

There are two types of lipoproteins that carry cholesterol through the blood: LDL and HDL. LDL ("bad" cholesterol) raises the risk of heart disease and stroke when in high levels, while HDL ("good" cholesterol) lowers the risk when in high levels by carrying cholesterol back to the liver. When too much LDL builds up as plaque in the blood vessels, it can block blood flow and cause heart attacks. Lowering LDL through medication and lifestyle changes and raising HDL through lifestyle changes can reduce heart disease risk.

LDL and HDL Cholesterol: "Bad" and "Good"

Cholesterol
Cholesterol travels through the blood on proteins called “lipoproteins.” Two types
of lipoproteins carry cholesterol throughout the body:

 LDL (low-density lipoprotein), sometimes called


“bad” cholesterol, makes up most of your body’s cholesterol. High levels of
LDL cholesterol raise your risk for heart disease and stroke.
 HDL (high-density lipoprotein), or “good” cholesterol, absorbs
cholesterol and carries it back to the liver. The liver then flushes it from the
body. High levels of HDL cholesterol can lower your risk for heart disease and
stroke.

When your body has too much LDL cholesterol, the LDL cholesterol can build up
on the walls of your blood vessels. This buildup is called “plaque.” As your blood
vessels build up plaque over time, the insides of the vessels narrow. This
narrowing blocks blood flow to and from your heart and other organs. When
blood flow to the heart is blocked, it can cause angina (chest pain) or a heart
attack.

Lowering Your Risk

 If you have high LDL cholesterol levels, your health care team may
recommend cholesterol-lowering medicine and lifestyle changes to lower
your risk for heart disease and stroke.
 If you have low HDL cholesterol levels, talk to your doctor about lifestyle
changes that may help raise your levels.

Kolesterol LDL dan HDL: Kolesterol "Buruk" dan "Baik"

Kolesterol berjalan melalui darah pada protein yang disebut "lipoprotein." Dua jenis lipoprotein
membawa kolesterol ke seluruh tubuh:

LDL (low-density lipoprotein), kadang-kadang disebut kolesterol "jahat", membentuk sebagian besar
kolesterol tubuh Anda. Kadar kolesterol LDL yang tinggi meningkatkan risiko penyakit jantung dan
stroke.

HDL (high-density lipoprotein), atau kolesterol "baik", menyerap kolesterol dan membawanya kembali
ke hati. Hati kemudian membersihkannya dari tubuh. Kadar kolesterol HDL yang tinggi dapat
menurunkan risiko penyakit jantung dan stroke.

Ketika tubuh Anda memiliki terlalu banyak kolesterol LDL, kolesterol LDL dapat menumpuk di dinding
pembuluh darah Anda. Penumpukan ini disebut "plak." Saat pembuluh darah Anda membentuk plak dari
waktu ke waktu, bagian dalam pembuluh menyempit. Penyempitan ini menghambat aliran darah ke dan
dari jantung dan organ-organ lain. Ketika aliran darah ke jantung tersumbat, itu dapat menyebabkan
angina (nyeri dada) atau serangan jantung.

Menurunkan Risiko Anda

Jika Anda memiliki kadar kolesterol LDL yang tinggi, tim perawatan kesehatan Anda dapat
merekomendasikan obat penurun kolesterol dan perubahan gaya hidup untuk menurunkan risiko
penyakit jantung dan stroke.

Jika Anda memiliki kadar kolesterol HDL rendah, bicarakan dengan dokter Anda tentang perubahan gaya
hidup yang dapat membantu meningkatkan kadar Anda.
