Definition


Dyslipidemia is a term for a modification of normal blood lipid levels. It refers, in current practice, to an excessive concentration of one or more types of lipids present in the blood. Dyslipidemia causes cholesterol deposits in the arteries and provokes atherosclerosis, which reduces the size of the artery and, in the long term, the blood flow through the affected vessel. Dyslipidemia is found in blood tests: levels of LDL cholesterol, atherogenic cholesterol or "bad" cholesterol, is higher because this cholesterol is primarily responsible for arterial deposits; HDL cholesterol, protective cholesterol or "good" cholesterol, protects against cardiovascular disease; triglycerides are also noted and are an indicator of diet.
