1. What is LDL Cholesterol?

LDL (Low-Density Lipoprotein) cholesterol, often referred to as "bad cholesterol," is a type of cholesterol that can build up in the arteries and increase the risk of heart disease and stroke. The target level of 2.4 mmol/L is considered desirable for cardiovascular health.

2. How Does the Calculator Work?

The calculator uses the Friedewald formula:

Where:

• \( TC \) — Total Cholesterol (mmol/L)
• \( HDL \) — HDL Cholesterol (mmol/L)
• \( TG \) — Triglycerides (mmol/L)

Explanation: This formula estimates LDL cholesterol levels based on measured values of total cholesterol, HDL cholesterol, and triglycerides.

3. Importance of LDL Calculation

Details: Monitoring LDL cholesterol levels is crucial for assessing cardiovascular risk and guiding treatment decisions. A level of 2.4 mmol/L is considered desirable for most adults.

4. Using the Calculator

Tips: Enter total cholesterol, HDL cholesterol, and triglycerides in mmol/L. All values must be valid and non-negative. For accurate results, use fasting lipid profile values.

5. Frequently Asked Questions (FAQ)

Q1: Why is 2.4 mmol/L considered desirable?
A: This level is associated with lower cardiovascular risk. Higher levels may require lifestyle changes or medication.

Q2: When should I get my cholesterol checked?
A: Adults should have a lipid profile every 4-6 years, or more frequently if you have risk factors for heart disease.

Q3: Are there limitations to this calculation?
A: The formula is less accurate when triglyceride levels are above 4.5 mmol/L. Direct LDL measurement may be needed in such cases.

Q4: How can I lower my LDL cholesterol?
A: Through diet (reduce saturated fats), exercise, weight management, and if needed, cholesterol-lowering medications.

Q5: Is this calculation valid for everyone?
A: While generally accurate, individual variations may occur. Always consult with a healthcare professional for personalized advice.
