Understanding Cholesterol
Cholesterol is a waxy, fat-like substance found in all cells of your body. Your body needs cholesterol to make hormones, vitamin D, and substances that help digest food. However, too much cholesterol in your blood can increase your risk of heart disease.
Total cholesterol is calculated using the Friedewald equation: Total Cholesterol = HDL + LDL + (Triglycerides/5). This formula provides an estimate when direct measurement isn't available.
Types of Cholesterol
- HDL (High-Density Lipoprotein): 'Good' cholesterol that helps remove other forms of cholesterol from your bloodstream
- LDL (Low-Density Lipoprotein): 'Bad' cholesterol that can build up in arteries and form plaque
- VLDL (Very Low-Density Lipoprotein): Estimated as Triglycerides/5, carries triglycerides in the blood
- Non-HDL Cholesterol: Total cholesterol minus HDL, includes all 'bad' cholesterol types
Important Cholesterol Ratios
Cholesterol ratios provide better cardiovascular risk assessment than individual values alone:
| Ratio | Optimal | Good | Moderate Risk | High Risk |
|---|---|---|---|---|
| Total/HDL | < 3.5 | 3.5-5.0 | 5.0-6.0 | > 6.0 |
| LDL/HDL | < 2.0 | 2.0-3.0 | 3.0-4.0 | > 4.0 |
How to Improve Cholesterol Levels
- Eat heart-healthy foods rich in omega-3 fatty acids, soluble fiber, and plant sterols
- Exercise regularly - aim for 30 minutes of moderate activity most days
- Quit smoking and limit alcohol consumption
- Maintain a healthy weight through diet and exercise
- Reduce saturated fats and eliminate trans fats from your diet
- Take prescribed medications as directed by your doctor
- Manage stress through relaxation techniques
- Get regular cholesterol screenings as recommended
Frequently Asked Questions
- What is a healthy total cholesterol level?
- Total cholesterol below 200 mg/dL is considered desirable. Levels between 200-239 mg/dL are borderline high, and 240 mg/dL or above is considered high. However, cholesterol ratios and individual component levels are also important for risk assessment.
- Why are cholesterol ratios important?
- Ratios like Total/HDL and LDL/HDL provide better cardiovascular risk prediction than total cholesterol alone. A lower ratio indicates better balance between good and bad cholesterol. The Total/HDL ratio is particularly useful for assessing heart disease risk.
- How accurate is this calculator?
- This calculator uses the standard Friedewald equation (Total = HDL + LDL + Triglycerides/5), which is widely used in clinical practice. However, it's less accurate when triglycerides are very high (>400 mg/dL). Always use actual lab results for medical decisions.
- How often should I check my cholesterol?
- Adults should have cholesterol checked every 4-6 years. Those with risk factors (family history, diabetes, heart disease) may need more frequent testing. Your healthcare provider will recommend the appropriate screening schedule for you.
