What Is VLDL?

The initials VLDL are an abbreviation for "very-low-density lipoproteins." It's an important factor in measuring how much unhealthy cholesterol is in the blood.

There are several major types of cholesterol. Each type contains a mixture of cholesterol, protein and triglycerides.

Other prominent types include:

Low density lipoprotein or LDL, which has recently become familiar to many people as "bad" cholesterol. LDL contains the highest amount of cholesterol.

High density lipoprotein or HDL, which is often referred to as "good" cholesterol. HDL contains the highest amount of protein.

VLDL contains the highest amount of triglyceride, which is a type of blood fat.

Like LDL cholesterol, VLDL has been associated with a higher risk of circulatory problems because the fats carried by VLDL can attach to the walls of blood vessels. When this happens, the pathways through the vessels become more narrow, or may even become blocked. Blocked arteries in the heart cause a heart attack. Blocked arteries in the brain cause a stroke.

Where Does VLDL Come From? 

VLDL is generated in the liver in response to a high-carbohydrate meal. The liver converts the extra carbohydrates into a type of fat called triglycerides. It is then converted in the bloodstream to LDL. VLDL particles have a diameter of 30-80 nm, which is rather large, meaning it can transport a lot of triglycerides.

You should undergo regular testing for cholesterol levels, but be aware that there's no simple, direct way to measure VLDL cholesterol. It's usually estimated as a percentage of your triglyceride value, but these values may vary somewhat among different laboratories. Talk to your doctor about the meaning of your specific test results.

A VLDL cholesterol level that measures between 5 and 40 milligrams per deciliter is considered normal.

Managing VLDL
 
People with any of the following risk factors should be especially aware of their VLDL levels:

• A family history of early coronary heart disease, or other lipid disorders.
• Diabetes & hypertension.
• Disorders of pancreas.
• Obesity.
• Those undergoing kidney replacements.
• Women in Menopause.

Even those who are not in these high risk groups should work at keeping their VLDL levels in the healthy range. Here are some tips:

• Exercise at least three times a week for 20-30 minutes.
• Eat low fat, low cholesterol foods.
• Stop smoking and limit alcohol consumption.
