1. What is Cholesterol Ratio?

The cholesterol ratio is calculated by dividing total cholesterol by HDL cholesterol. It provides a more comprehensive assessment of cardiovascular risk than either value alone, with lower ratios indicating better heart health.

2. How Does the Calculator Work?

The calculator uses the cholesterol ratio formula:

Where:

• Total Cholesterol — Measured in millimoles per liter (mmol/L)
• HDL — High-density lipoprotein cholesterol measured in mmol/L

Explanation: This ratio compares your total cholesterol level to your "good" HDL cholesterol, providing insight into your cardiovascular health risk.

3. Importance of Cholesterol Ratio

Details: A lower cholesterol ratio indicates a lower risk of heart disease. Generally, a ratio below 5:1 is considered good, with the ideal ratio being below 3.5:1.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy cholesterol ratio?
A: A ratio of 5:1 or lower is considered good, with the ideal ratio being 3.5:1 or lower. Higher ratios indicate increased cardiovascular risk.

Q2: Why use ratio instead of individual values?
A: The ratio provides a better overall picture of cholesterol balance and cardiovascular risk than either value alone.

Q3: How often should I check my cholesterol?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if you have risk factors for heart disease.

Q4: Can I improve my cholesterol ratio?
A: Yes, through lifestyle changes like regular exercise, healthy diet (reducing saturated fats), maintaining healthy weight, and if needed, medication.

Q5: Are there other important cholesterol measurements?
A: Yes, LDL (bad cholesterol) and triglycerides are also important indicators of cardiovascular health that should be monitored.
