1. What is HDL Cholesterol?

HDL (High-Density Lipoprotein) cholesterol is often referred to as "good cholesterol" because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL are associated with a lower risk of heart disease.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ HDL = TC - LDL - \frac{TG}{5} \]

Where:

\( HDL \) — High-Density Lipoprotein cholesterol (mg/dL)
\( TC \) — Total Cholesterol (mg/dL)
\( LDL \) — Low-Density Lipoprotein cholesterol (mg/dL)
\( TG \) — Triglycerides (mg/dL)

Explanation: This formula calculates HDL cholesterol by subtracting LDL cholesterol and one-fifth of triglycerides from total cholesterol.

3. Importance of HDL Calculation

Details: Monitoring HDL levels is crucial for assessing cardiovascular health. HDL helps transport cholesterol from arteries to the liver for removal, reducing plaque buildup and lowering heart disease risk.

4. Using the Calculator

Tips: Enter total cholesterol, LDL cholesterol, and triglycerides in mg/dL. All values must be valid (positive numbers). For accurate results, use fasting lipid panel values.

5. Frequently Asked Questions (FAQ)

Q1: What are normal HDL values?
A: For men: 40 mg/dL or higher; For women: 50 mg/dL or higher. Higher values are generally better for heart health.

Q2: Why divide triglycerides by 5 in the formula?
A: This accounts for the cholesterol content in very low-density lipoproteins (VLDL), which is estimated as approximately one-fifth of triglyceride levels.

Q3: When should lipid levels be measured?
A: A fasting lipid panel (9-12 hour fast) provides the most accurate results, as triglyceride levels can be significantly affected by recent food intake.

Q4: Are there limitations to this calculation method?
A: This formula becomes less accurate when triglyceride levels exceed 400 mg/dL. Direct HDL measurement is preferred in such cases.

Q5: How can I increase my HDL levels?
A: Regular exercise, healthy fats (olive oil, avocados, nuts), quitting smoking, and moderate alcohol consumption may help raise HDL levels.
