1. What is Cholesterol Ratio?

The cholesterol ratio is a simple calculation that compares your total cholesterol level to your HDL (good) cholesterol level. It provides a quick assessment of cardiovascular risk and is commonly used in Australian healthcare settings.

2. How to Calculate Cholesterol Ratio

The cholesterol ratio is calculated using the formula:

Where:

• Total Cholesterol — Measured in millimoles per liter (mmol/L)
• HDL Cholesterol — Measured in millimoles per liter (mmol/L)

Explanation: This ratio helps assess cardiovascular risk by comparing the amount of total cholesterol to the protective HDL cholesterol.

3. Importance of Cholesterol Ratio

Details: A lower ratio indicates better cardiovascular health. Generally, a ratio below 4.0 is considered desirable, while ratios above 5.0 may indicate increased heart disease risk.

4. Using the Calculator

Tips: Enter both total cholesterol and HDL cholesterol 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 good cholesterol ratio in Australia?
A: A ratio below 4.0 is generally considered good, 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, healthy diet, maintaining healthy weight, and if needed, medication.

Q4: Is the cholesterol ratio more important than individual numbers?
A: Both are important. The ratio provides context, but individual cholesterol levels also need to be within healthy ranges.

Q5: What's the difference between mmol/L and mg/dL measurements?
A: Australia uses mmol/L while some countries use mg/dL. To convert mmol/L to mg/dL, multiply by 38.67.
