Why is LDL cholesterol "bad"?

Low-density lipoprotein cholesterol, also known as LDL cholesterol, refers to a type of cholesterol that is found in the body. It is transported through the bloodstream by lipoproteins. LDL particles are smaller and denser than other types of lipoproteins, which makes them more likely to deposit cholesterol in the arterial walls.

Although cholesterol is essential in the body, as it aids hormone production, forms a key component of cell membranes, and supports vitamin D synthesis, too much of it can have negative effects.

LDL type of cholesterol is sometimes referred to as ‘bad’ cholesterol because its accumulation can lead to plaque build-up in the arteries.

When the arteries are filled with plaque, it causes their lumens (interior) to become narrow. This can reduce blood flow and lead to higher blood pressure. In turn, it can increase the risk of cardiovascular disease and stroke.

Cholesterol deposits can become inflamed or rupture, leading to the formation of blood clots and further increasing the risk of heart-related events.
