Cholesterol travels in our bodies in lipoproteins, which are protein-covered fats. There are two main types of lipoproteins: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Maintaining healthy levels of both types of cholesterol is vital for health.
High levels of LDL (known as “bad” cholesterol) can build up in arteries of the body. HDL is referred to as the “good” kind of cholesterol because it takes cholesterol from other parts of the body to your liver, which removes cholesterol from your body and helps manage it.
Having high LDL cholesterol can build up on the artery walls and cause a narrowing of the arteries. This can limit the flow of blood to and from your heart and brain, which can lead to a heart attack or stroke.
Simple blood tests can help keep tabs on your cholesterol levels.
