Hyperlipidemias are defined as "conditions with excess lipids in the blood."[2]Hyperlipidemias include hypercholesterolemia and hypertriglyceridemia.


Hypolipoproteinemias are defined as "conditions with abnormally low levels of lipoproteins in the blood. This may involve any of the lipoprotein subclasses, including alpha-lipoproteins (high-density lipoproteins); beta-lipoproteins (low-density lipoproteins); and prebeta-lipoproteins (very-low-density lipoproteins)."[3] Hypolipoproteinemias include hypoalphalipoproteinemia (HDL Lipoprotein Deficiency Disease).
