Cholesterol Levels Explained: HDL, LDL, and What Your Numbers Mean

Why Cholesterol Matters

Cholesterol is a waxy substance found in your blood. While your body needs some cholesterol to build healthy cells, too much can increase your risk of heart disease and stroke.

A standard lipid panel measures four key values: total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. Understanding what each one means is essential for managing your heart health.

The Four Key Numbers

Total Cholesterol

This is the overall amount of cholesterol in your blood. Desirable levels are below 200 mg/dL. Between 200-239 mg/dL is considered borderline high, and 240 mg/dL or above is high.

LDL Cholesterol (The "Bad" One)

LDL stands for Low-Density Lipoprotein. It carries cholesterol to your arteries, where it can build up as plaque. This is why it's called "bad" cholesterol.

Optimal LDL is below 100 mg/dL. Near-optimal is 100-129 mg/dL. Borderline high is 130-159 mg/dL. High is 160-189 mg/dL. Very high is 190 mg/dL and above.

HDL Cholesterol (The "Good" One)

HDL stands for High-Density Lipoprotein. It acts like a cleanup crew, carrying cholesterol away from your arteries and back to your liver for removal. Higher levels are better.

For men, HDL below 40 mg/dL is considered a risk factor. For women, below 50 mg/dL is risky. HDL above 60 mg/dL is considered protective against heart disease.

Triglycerides

Triglycerides are a type of fat in your blood. Your body converts unused calories into triglycerides and stores them in fat cells.

Normal triglycerides are below 150 mg/dL. Borderline high is 150-199 mg/dL. High is 200-499 mg/dL. Very high is 500 mg/dL and above.

How to Improve Your Cholesterol

Lifestyle changes can make a significant impact on your cholesterol levels. Focus on eating heart-healthy foods rich in omega-3 fatty acids, increasing soluble fiber, and reducing saturated and trans fats. Regular exercise can raise HDL cholesterol, and maintaining a healthy weight reduces LDL and triglycerides.

If lifestyle changes alone are not enough, your doctor may recommend statin medications. These drugs can significantly lower LDL cholesterol and reduce cardiovascular risk.
