1. What is the LDL/HDL Ratio?

The LDL/HDL ratio is a calculated value that compares the amount of "bad" cholesterol (LDL) to "good" cholesterol (HDL) in your blood. This ratio provides a more comprehensive assessment of cardiovascular risk than looking at LDL or HDL levels alone.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( LDL \) — Low-density lipoprotein cholesterol level (mmol/L)
• \( HDL \) — High-density lipoprotein cholesterol level (mmol/L)

Explanation: The ratio is calculated by dividing your LDL cholesterol value by your HDL cholesterol value. A lower ratio indicates a lower risk of heart disease.

3. Importance of LDL/HDL Ratio

Details: The LDL/HDL ratio is considered a better predictor of heart disease risk than individual cholesterol numbers. It helps assess the balance between harmful and protective cholesterol in your bloodstream.

4. Using the Calculator

Tips: Enter both LDL and HDL values in mmol/L (UK standard units). Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy LDL/HDL ratio?
A: Generally, a ratio below 3.5:1 is considered optimal, with lower values indicating better cardiovascular health.

Q2: How often should I check my cholesterol ratio?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if you have risk factors for heart disease.

Q3: Can I improve my cholesterol ratio?
A: Yes, through lifestyle changes like regular exercise, a heart-healthy diet, maintaining a healthy weight, and if necessary, medication.

Q4: Are there limitations to this ratio?
A: While useful, the ratio should be interpreted alongside other risk factors like blood pressure, diabetes, smoking status, and family history.

Q5: Should I fast before cholesterol testing?
A: For the most accurate results, a 9-12 hour fast is typically recommended before cholesterol testing.
