1. What Is LDL Cholesterol?

LDL (Low-Density Lipoprotein) cholesterol, often called "bad cholesterol," can build up in the walls of your arteries, making them hard and narrow. Higher levels of LDL cholesterol raise your risk for heart disease and stroke.

2. Understanding LDL Levels

LDL cholesterol levels are measured in millimoles per liter (mmol/L):

Classification:

• Optimal: Less than 2.6 mmol/L
• Near Optimal: 2.6-3.3 mmol/L
• Borderline High: 3.4-4.1 mmol/L
• High: 4.1-4.9 mmol/L
• Very High: Greater than 4.9 mmol/L

3. Importance of LDL Measurement

Details: Monitoring LDL cholesterol is crucial for assessing cardiovascular risk and guiding treatment decisions. High LDL levels are a major modifiable risk factor for atherosclerosis and coronary artery disease.

4. Using the Calculator

Tips: Enter your LDL cholesterol value in mmol/L. The calculator will classify your level as normal or high based on clinical guidelines.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy LDL level?
A: For most adults, an LDL level below 3.4 mmol/L is considered desirable. For those with heart disease or diabetes, targets may be lower (below 2.6 mmol/L or even below 1.8 mmol/L).

Q2: How often should I check my LDL?
A: Adults should have their cholesterol checked every 4-6 years. Those with risk factors may need more frequent testing.

Q3: How can I lower my LDL cholesterol?
A: Lifestyle changes include a heart-healthy diet, regular exercise, maintaining a healthy weight, and quitting smoking. Medications like statins may be prescribed if needed.

Q4: Are there symptoms of high LDL?
A: High cholesterol typically has no symptoms. It's often discovered through blood tests after health problems have developed.

Q5: What factors affect LDL levels?
A: Diet, weight, physical activity, age, gender, genetics, and certain medical conditions can all influence LDL cholesterol levels.
