What is cholesterol?-the silent killer

What is cholesterol?

Cholesterol forms part of the outer membrane that surrounds every cell. It’s used to insulate nerve fibres (and so make nerve signals travel properly) and make hormones, which carry chemical signals around the body.

Without cholesterol, your body wouldn’t work – it’s vital to ensure the body’s normal function.

Too much cholesterol in the blood, however, increases the risk of coronary heart disease and disease of the arteries.
