Are there different types of cholesterol?

Cholesterol travels through the blood in different types of packages, called lipoproteins.

Low-density lipoproteins (LDL) deliver cholesterol to the body. High-density lipoproteins (HDL) remove cholesterol from the bloodstream.

This is why too much LDL cholesterol is bad for the body, while the HDL form is good. It's the balance between the types of cholesterol that tells you what your cholesterol level means (see the box below).

For example, if your total cholesterol level is high because of a high LDL level, you may be at higher risk of heart disease or stroke. If your total level is high only because of a high HDL level, you're probably not at higher risk."
