Cholesterol is a waxy substance which is made in the body by the liver but is also found in some foods. It plays a vital role in how every cell works and is also needed to make Vitamin D, some hormones and bile for digestion. However, too much cholesterol in the blood can increase your risk of getting heart and circulatory diseases.
Cholesterol is made up of both good (HDL) and bad (LDL) cholesterol so it is important to investigate a raised cholesterol result to determine the cause. High levels of HDL cholesterol can cause a raised cholesterol result but may actually be protective against heart disease.
