hyperlipidaemia

A variety of conditions in which there are increased concentrations of lipids in plasma: phospholipids, triacylglycerols, free and esterified cholesterol, or unesterified fatty acids. Familial hyperlipidaemias are due to genetic diseases; less severe hyperlipidaemia is commonly seen in people in affluent developed countries, associated with increased risk of atherosclerosis and ischaemic heart disease.
