Dyslipidemia is an abnormal amount of lipids (e.g. triglycerides, cholesterol and/or fat phospholipids) in the blood. In developed countries, most dyslipidemias are hyperlipidemias; that is, an elevation of lipids in the blood. This is often due to diet and lifestyle. Prolonged elevation of insulin levels can also lead to dyslipidemia. Likewise, increased levels of O-GlcNAc transferase (OGT) may cause dyslipidemiaHyperlipidemia is abnormally elevated levels of any or all lipids or lipoproteins in the blood. Hyperlipidemia is an umbrella term that refers to acquired or genetic disorders that result in high levels of lipids (fats, cholesterol, or triglycerides) circulating in the blood.[3] This disease is usually chronic and requires ongoing medication to control blood lipid levels.
