Cholesterol

Alternate Names

  • Blood Cholesterol
  • Total Cholesterol

Cholesterol is a fat that mainly comes from meat in the diet, which is then converted in the liver. Three-quarters of cholesterol is bound to low-density lipoproteins (LDL), one-quarter is bound to high-density lipoproteins (HDL) and very low-density lipoproteins (VLDL). Once cholesterol is bound to lipoproteins, the cholesterol is moved through the bloodstream. Cholesterol testing is usually done as part of a lipid profile. High blood cholesterol levels are associated with coronary artery disease, and the development of heart disease. High blood levels are also seen in people with an under-active thyroid gland, cirrhosis, hypertension, uncontrolled DM (diabetes mellitus), pregnancy, or stress. Low blood levels are seen in people with anemia, liver disease, malnutrition, stress, or sepsis. Many medications can affect cholesterol levels.
