Hyperlipidemia

What is Hyperlipidemia?

Hyperlipidemia is an excess of fatty substances called lipids, largely cholesterol and triglycerides, in the blood. It is also called hyperlipoproteinemia because these fatty substances travel in the blood attached to proteins. This is the only way that these fatty substances can remain dissolved while in circulation.

Hyperlipidemia, in general, can be divided into two subcategories:

  • Hypercholesterolemia  – high level of cholesterol
  • Hypertriglyceridemia  – high level of triglycerides, the most common form of fat

Reference ranges for your serum lipids

Total cholesterol <200 200 – 239 >240
LDL cholesterol 70 – 129 130 – 159 >160
Triglycerides <150 150 – 199 >200
VLDL cholesterol <20 20 – 40 >40
