Cholesterol can be both a good and bad substance in the body,
depending on levels and which kind. Cholesterol helps digest
dietary fats, produce hormones, build cell walls, and aid with
other bodily functions. Cholesterol is carried through the
bloodstream to the body’s tissues, where it is used, stored, or
excreted, depending on the body’s needs. Cholesterol is referred
to as lipoproteins, which can be either good or bad for your
health. Some lipoproteins can cause blood flow to the heart to
slow down, which can lead to the heart muscle becoming starved
of oxygen, resulting in chest pain known as angina. Blood clots
that fully block coronary arteries can also occur, causing heart
attacks (myocardial infarction) or death.
