1. What is Cholesterol Ratio?

The cholesterol ratio is calculated by dividing your total cholesterol value by your HDL cholesterol level. It's a simple way for healthcare providers to assess cardiovascular risk.

2. How to Calculate Cholesterol Ratio

The cholesterol ratio formula is:

Where:

• Total Cholesterol — The sum of all cholesterol types in your blood (mmol/L)
• HDL Cholesterol — High-density lipoprotein, the "good" cholesterol (mmol/L)

Explanation: A lower ratio generally indicates a lower risk of heart disease, while a higher ratio suggests higher risk.

3. Importance of Cholesterol Ratio

Details: The cholesterol ratio provides a more comprehensive cardiovascular risk assessment than looking at total cholesterol alone, as it considers the protective effect of HDL cholesterol.

4. Using the Calculator

Tips: Enter your total cholesterol and HDL cholesterol values in mmol/L units. Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy cholesterol ratio?
A: Generally, a ratio below 4:1 is considered healthy, with the ideal ratio being around 3.5:1 or lower.

Q2: Why use mmol/L instead of mg/dL?
A: mmol/L (millimoles per liter) is the standard unit used in most countries outside the United States for cholesterol measurements.

Q3: 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.

Q4: Can I improve my cholesterol ratio?
A: Yes, through lifestyle changes like regular exercise, a heart-healthy diet, maintaining a healthy weight, and quitting smoking.

Q5: Is the cholesterol ratio more important than individual numbers?
A: Both are important. While the ratio provides context, healthcare providers also consider individual cholesterol values and other risk factors.
