Metabolic disorders that are characterized by high levels of lipids in the blood. Hyperlipidaemias may be inherited or associated with another disorder, such as hypothyroidism, diabetes mellitus, kidney failure, or Cushing’s syndrome. They may also be a result of use of corticosteroid drugs. Hyperlipidaemias are associated with atherosclerosis and coronary artery disease. The signs depend on the type of hyperlipidaemia and may include fatty nodules in the skin or over joints, and a white line around the rim of the cornea. Diagnosis depends on blood tests. Treatment aims to reduce blood lipid levels, usually by a low-fat diet and lipid-lowering drugs.
