Dyslipidemia

Dyslipidemia or dyslipidaemia is an abnormal amount of lipids (e.g. cholesterol and/or fat) in the blood. In developed countries, most dyslipidemias are hyperlipidemias; that is, an elevation of lipids in the blood, often due to diet and lifestyle. The prolonged elevation of insulin levels can lead to dyslipidemia. Increased levels of O-GlcNAc transferase (OGT) are known to cause dyslipidemia.

Classification
There are two major ways in which dyslipidemias are classified:


 * Phenotype, or the presentation in the body (including the specific type of lipid that is increased)
 * Etiology, or the reason for the condition (genetic, or secondary to another condition.) This classification can be problematic, because most conditions involve the intersection of genetics and lifestyle issues. However, there are a few well-defined genetic conditions that are usually easy to identify.
