Cholesterol to HDL Ratio Formula:
| From: | To: |
The cholesterol to HDL ratio is a calculation used to assess cardiovascular risk. It compares the total amount of cholesterol in your blood to the amount of high-density lipoprotein (HDL) cholesterol, often referred to as "good" cholesterol.
The calculator uses the simple ratio formula:
Where:
Explanation: This ratio provides a better indicator of heart disease risk than total cholesterol alone, as it considers the protective effect of HDL cholesterol.
Details: A lower 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. This calculation is particularly important in the UK healthcare system where cholesterol is measured in mmol/L.
Tips: Enter both total cholesterol and HDL cholesterol values in mmol/L (the standard unit used in the UK). Both values must be greater than zero for accurate calculation.
Q1: What is a healthy cholesterol ratio?
A: A ratio below 5:1 is considered good, with the ideal ratio being below 3.5:1. Higher ratios indicate increased cardiovascular risk.
Q2: Why is this ratio important?
A: It provides a better assessment of heart disease risk than total cholesterol alone because it considers the protective effect of HDL cholesterol.
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 if necessary, medication prescribed by your doctor.
Q5: Is this calculator specific to the UK?
A: Yes, this calculator uses mmol/L units which are the standard measurement for cholesterol in the UK and most European countries.
