Many factors can contribute to high cholesterol, but the good news is there are things you can do to control them.
Cholesterol is essential for life. It helps to build cell walls and is used in the manufacture of some hormones.
Although the body needs a certain amount of cholesterol, when there is more cholesterol circulating in the blood than the body needs the cholesterol can build up on the artery walls. This eventually leads to narrowing and hardening of the arteries, a process called atherosclerosis.
Atherosclerosis increases the risk of heart disease and stroke. This risk is increased when other risk factors such as high blood pressure and a family history of heart disease are also present.
