hyperlipidemia type V, a condition of elevated blood lipid levels, characterized by slightly increased cholesterol level, greatly increased triglyceride level, elevation of the triglyceride carrier protein (very-low-density lipoprotein) level, and above-normal levels of chylomicrons. It is a genetically heterogenous disorder that apparently does not increase the risk of atherosclerosis. Treatment includes weight control, a low-fat diet, drugs, niacin, and abstinence from alcohol. Also called mixed hyperlipemia, mixed hypertriglyceridemia.
