LDL/HDL Ratio Calculator

What is the LDL/HDL Ratio?

The LDL/HDL ratio is calculated by dividing your Low-Density Lipoprotein (LDL) cholesterol, often called "bad" cholesterol, by your High-Density Lipoprotein (HDL) cholesterol, known as "good" cholesterol.

This ratio is considered by many experts to be a more accurate predictor of cardiovascular disease risk than just looking at LDL or Total Cholesterol levels alone, as it reflects the balance between atherogenic (plaque-forming) and anti-atherogenic particles.

Why is this Ratio Important?

  • It provides a clearer picture of your risk for developing atherosclerosis (hardening of the arteries).
  • A lower ratio is desirable, indicating a healthier balance of cholesterol types.
  • It is a simple, no-cost calculation that enhances the value of a standard lipid panel.

Interpreting the Result

Ideal Ratio (< 2.0): This ratio is considered optimal and indicates a very low cardiovascular risk.
Good (2.0 - 4.0): This is a good, healthy range for most individuals.
Borderline High (4.0 - 6.0): This ratio indicates a moderate or borderline cardiovascular risk. Lifestyle improvements are recommended.
High Risk (> 6.0): This ratio suggests a significantly increased risk of cardiovascular disease. Medical consultation is strongly advised.

How to Improve Your LDL/HDL Ratio

Improving your ratio involves lowering LDL and/or raising HDL. This is often achievable through lifestyle changes:

  • Increase soluble fiber intake (oats, beans, apples).
  • Choose healthy fats (avocados, nuts, olive oil) over saturated and trans fats.
  • Engage in regular aerobic exercise to raise HDL levels.
  • Maintain a healthy weight and quit smoking.
  • Consult your physician for personalized advice and potential medical treatments.
