Hyperlipidemia is a medical term that means your blood has too many lipids (fats) in it. The higher your level of low-density lipoprotein (LDL) cholesterol, the "bad" cholesterol, and the lower your level of high-density lipoprotein (HDL), the "good" cholesterol, the higher your risk of cardiovascular disease. Certain genetic conditions may also cause high cholesterol levels.
Hyperlipidemia can often be improved by lifestyle changes. This is true even if high cholesterol is due to genetics. From a dietary standpoint, the best way to lower your cholesterol is reduce saturated fat and trans fat. A sedentary lifestyle lowers HDL cholesterol. Less HDL cholesterol means there’s less good cholesterol to remove LDL (bad) cholesterol from arteries. Losing excess weight can also improve cholesterol levels.
