Cholesterol Risk Ratio Formula:
| From: | To: |
The Cholesterol Risk Ratio (Total Cholesterol/HDL Ratio) is a simple calculation that helps assess cardiovascular risk. It compares the total amount of cholesterol in your blood to the amount of "good" HDL cholesterol, providing a more comprehensive picture than either value alone.
The calculator uses the simple ratio formula:
Where:
Interpretation: A ratio greater than 5 indicates high cardiovascular risk, while a ratio of 5 or below is considered normal.
Details: Monitoring your cholesterol ratio is important for assessing cardiovascular health. A high ratio indicates an increased risk of heart disease, stroke, and other cardiovascular problems, even if individual cholesterol numbers appear normal.
Tips: Enter your total cholesterol and HDL values in mg/dL. Both values must be greater than zero. For accurate results, use values from recent blood tests.
Q1: What is a healthy cholesterol ratio?
A: A ratio below 5 is considered healthy. The ideal ratio is below 3.5 for optimal 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, a heart-healthy diet, maintaining a healthy weight, and if necessary, medication prescribed by your doctor.
Q4: Which is more important - individual numbers or the ratio?
A: Both are important. Healthcare providers consider all cholesterol values (total, HDL, LDL, and triglycerides) along with the ratio to get a complete picture of your cardiovascular health.
Q5: Are there limitations to this ratio?
A: While useful, the ratio should be considered alongside other risk factors like age, family history, blood pressure, smoking status, and diabetes.
