Total Cholesterol

Total cholesterol measures all the cholesterol types in your blood, providing a snapshot of your overall heart health.

📋 About This Biomarker

Total cholesterol represents the sum of all the cholesterol particles in your blood, including low-density lipoprotein (LDL or 'bad' cholesterol), high-density lipoprotein (HDL or 'good' cholesterol), and very-low-density lipoprotein (VLDL). Cholesterol is essential for producing hormones, digesting fats, and maintaining cell membrane integrity. However, too much cholesterol, particularly LDL, can lead to plaque buildup in arteries and increase the risk of heart disease or stroke. Measuring total cholesterol provides a broad overview of your cholesterol levels and helps evaluate your risk for cardiovascular diseases, guiding lifestyle changes or medical interventions to improve heart health.

🎯 Why We Test This

Testing total cholesterol is important for anyone at risk of heart disease, such as those with high blood pressure, diabetes, or a family history of heart issues. It’s also crucial for monitoring the effectiveness of cholesterol-lowering medications and lifestyle changes. Regular testing can help catch cholesterol problems early and reduce the risk of developing heart attacks or strokes.

⚠️ What Affects It

Several factors can influence total cholesterol levels, including diet, genetics, age, exercise habits, alcohol consumption, and conditions like diabetes or hypothyroidism. Medications such as statins or corticosteroids can also impact cholesterol levels.

📈 How to Improve

Managing high total cholesterol involves dietary changes to reduce saturated and trans fats, increasing physical activity, and quitting smoking. If low, ensure your diet includes healthy fats and is balanced overall. Regular monitoring and working with a healthcare provider are crucial.

📊 Understanding Your Results (mmol/L)

Low
Very low total cholesterol levels are rare but could result from conditions like hyperthyroidism, malnutrition, or certain genetic disorders. Consulting with a healthcare provider is essential to identify any underlying health issues.
Optimal
Normal total cholesterol levels suggest that your cholesterol balance is healthy, likely with good levels of HDL cholesterol and moderate levels of LDL cholesterol. Maintaining a balanced diet and regular exercise can help sustain these levels. f your total cholesterol is nearing the high end, it's a sign to reassess your diet, exercise, and overall lifestyle. Making small changes early on can prevent further increases and reduce your risk of heart disease. Levels near the lower end of the normal range generally aren’t a concern. They suggest low levels of harmful cholesterol, which is often beneficial for your heart health.
High (> 5.6 mmol/L)
Elevated total cholesterol indicates that the sum of all cholesterol types in your blood is too high. This could signal an increased risk of developing cardiovascular diseases. It often means that LDL cholesterol levels are also elevated, suggesting that lifestyle changes or medications may be necessary.
