1. What is Non-HDL Cholesterol?

Non-HDL cholesterol represents all atherogenic (artery-clogging) cholesterol particles, including LDL, VLDL, and lipoprotein(a). It's calculated by subtracting HDL cholesterol from total cholesterol.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( TC \) — Total Cholesterol (mg/dL)
• \( HDL \) — HDL Cholesterol (mg/dL)

Explanation: This calculation provides a comprehensive measure of all cholesterol particles that contribute to atherosclerosis.

3. Importance of Non-HDL Calculation

Details: Non-HDL cholesterol is considered a better predictor of cardiovascular risk than LDL cholesterol alone, as it includes all atherogenic particles.

4. Using the Calculator

Tips: Enter total cholesterol and HDL cholesterol values in mg/dL. Both values must be positive, and total cholesterol should be greater than or equal to HDL cholesterol.

5. Frequently Asked Questions (FAQ)

Q1: Why is non-HDL cholesterol important?
A: Non-HDL cholesterol provides a more complete picture of cardiovascular risk by including all harmful cholesterol particles, not just LDL.

Q2: What are optimal non-HDL cholesterol levels?
A: Optimal levels are typically 30 mg/dL above your LDL target. For most adults, levels below 130 mg/dL are desirable.

Q3: How often should cholesterol be measured?
A: Adults should have cholesterol checked every 4-6 years, or more frequently if risk factors are present.

Q4: Can non-HDL be too low?
A: Extremely low non-HDL levels are rare but may occur in some medical conditions. Generally, lower is better for cardiovascular health.

Q5: How can I lower my non-HDL cholesterol?
A: Lifestyle changes including healthy diet, regular exercise, weight management, and if needed, cholesterol-lowering medications.
