Some diseases such as diabetes, hypothyroidism, and kidney disease can also cause hyperlipidemia. People with FH have increased blood levels of low-density lipoprotein (LDL) cholesterol, sometimes called “bad cholesterol.”. Pathophysiology of Hyperlipidemia Hyperlipidemia can increase the chances of generating lipid oxidation products, which gradually accumulate in the mitochondria of cells and impact the whole body.

Hyperlipidemia is a group of disorders of lipoprotein metabolism entailing elevated blood levels of certain forms of cholesterol and triglyceride. a condition in which there are elevated levels of cholesterol in the blood. These high levels reflect underlying changes in lipoproteins, and could be caused by overproduction, reduced catabolism or both. The more hyperglycemic untreated NIDDM and insulin-dependent diabetic (IDDM) patient have mild to moderate hypertriglyceridemia due to decreased adipose tissue and muscle lipoprotein lipase, (LPL) activity.
