1. What is Cholesterol Ratio?

The cholesterol ratio is a simple calculation that compares your total cholesterol to your HDL (high-density lipoprotein) cholesterol. In Canada, this measurement is typically calculated using mmol/L units and provides insight into cardiovascular health risk.

2. How Does the Calculator Work?

The calculator uses the cholesterol ratio formula:

Where:

• Total Cholesterol — Measured in mmol/L
• HDL — High-density lipoprotein measured in mmol/L

Explanation: The ratio provides a better indicator of heart disease risk than total cholesterol alone, as it accounts for the protective effects of HDL cholesterol.

3. Importance of Cholesterol Ratio

Details: A lower cholesterol ratio indicates a lower risk of heart disease. Canadian guidelines suggest aiming for a ratio below 5:1, with the ideal ratio being 3.5:1 or lower.

4. Using the Calculator

Tips: Enter both total cholesterol and HDL values in mmol/L (Canadian 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: In Canada, a ratio below 5:1 is considered acceptable, while a ratio of 3.5:1 or lower is considered ideal for heart 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 such as regular exercise, healthy diet (reducing saturated fats), maintaining healthy weight, and if needed, medication.

Q4: What's the difference between Canadian and US cholesterol measurements?
A: Canada uses mmol/L while the US uses mg/dL. To convert, multiply mmol/L by 38.67 to get mg/dL.

Q5: Should I fast before cholesterol testing?
A: For the most accurate results, fasting for 9-12 hours before the test is typically recommended in Canada.
