This document discusses hyperlipidemia and its treatment. It begins by describing how lipids are transported through the body by chylomicrons and lipoproteins like LDL and HDL. High LDL and oxidized LDL can lead to atherosclerosis. Causes of high lipids include diet, diseases, and medications. Treatment involves lifestyle changes and lipid-lowering drugs like statins, fibrates, bile acid sequestrants, nicotinic acid, and ezetimibe. These drugs work to lower LDL and triglycerides and raise HDL to reduce cardiovascular risk. Side effects of the drugs are also outlined.
