What is LDL (low-density lipoproteins) – level and diet

Overview of cholesterol (low-density lipoproteins)

Cholesterol is a waxy substance found in the body cells. The liver helps in its synthesis and it is also found in few food sources. The body needs some amount of cholesterol to function properly. However, too much of it causes coronary artery disease.

It is mainly of two types:

  • LDL or low-density lipoproteins:

    It is known as the “bad” cholesterol because its high buildup causes blockage in arteries.

 

  • HDL or high-density lipoproteins:

    It is known as the “good” cholesterol because it helps in carrying cholesterol from other parts back to the liver which further removes it.

 

 

Can high LDL impose any risks for other diseases?

High LDL levels lead to plaque formation in arteries and lead to atherosclerosis. Coronary artery disease is the next to happen in series after plaque buildup. High DL might also cause angina, heart attack, and stroke in extreme cases.

 

How can I get to know my LDL level?

A blood test can help in letting you know your cholesterol values. How often you should get it done depends on your age, family history, and if any risk factors are involved due to some other diseases.

Following are few general recommendations:

 

In children:

The test must be done every 5 years however some children heart issues and stroke after birth so the test can be done earlier.

  • Age, Race, and Gender:

    Usually increasing age leads to the rise in cholesterol levels. But conditions like menopause which affects women and causes decrease in total cholesterol levels than men of same age. Few races like Asian and Afro American tend to exhibit high cholesterol levels than others.

 

  • Genetics or heredity:

    Your genes play a lead role in determining the amount of cholesterol the body produces. High cholesterol can run in families. For example, familial hypercholesterolemia (FH) is a type of inherited disease of high blood cholesterol.

  • Other medical conditions. Diseases like chronic kidney disease, diabetes, and HIV affects cholesterol levels and raises it to high values.

 

 

What is the ideal, recommended range of LDL level?

Following is the recommended range for LDL levels although slight variations might occur as reference range might vary from lab to lab.

 

Less than 100 mg/d of LDL falls under the category of optimal range

It needs to be between 100-129 mg/dL falls under the category of near-optimal or above the optimal range

LDL between 130-159 mg/dL falls under the category of borderline high range

Doactors prefer LDL between 160-189 mg/dL falls under the category of high range
