LDL cholesterol

LDL cholesterol (Low-Density Lipoprotein cholesterol) is a type of cholesterol that is often referred to as "bad cholesterol". High levels of LDL cholesterol can lead to atherosclerosis, a condition that can increase the risk of heart disease and stroke.

Overview

LDL cholesterol is one of the five major groups of lipoprotein which transport all fat molecules around the body in the extracellular water. These groups, from least dense, compared to surrounding water (largest particles) to most dense (smallest particles), are chylomicrons, very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein and high-density lipoprotein (HDL).

Health Risks

High levels of LDL cholesterol can lead to a buildup of cholesterol in the arteries, known as atherosclerosis. This can cause the arteries to narrow and harden, increasing the risk of heart disease and stroke.

Measurement

LDL cholesterol levels are typically measured as part of a lipid panel during a routine medical examination. The levels are usually expressed in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L).

Treatment

Treatment for high LDL cholesterol typically involves lifestyle changes such as diet and exercise, and may also include medication such as statins.
