Lipid disorders are a group of conditions characterized by abnormal levels of fatty substances in the blood called lipoproteins and triglycerides. Also called "dyslipidemias," common lipid disorders include:
- too high levels of low-density lipoproteins (LDL) known as the "lousy" or "bad" cholesterol because it contributes to the formation of plaque in your arteries, raising your risk for heart attack and stroke.
- too low levels of high-density lipoproteins (HDL) known as the "healthy" or "good" cholesterol because it helps to sweep cholesterol out of the blood vessels, reducing plaque build-up and lowering heart attack or stroke risk.
- too high levels of triglycerides, a type of fat found in your blood that can also raise heart attack and stroke risk.
- They have diabetes.
- They smoke.
- They are overweight or obese.
- They have high blood pressure.
