What is a normal Total Cholesterol level?
Total cholesterol is a legacy aggregate metric — the sum of LDL, HDL, and VLDL cholesterol, typically estimated via the Friedewald equation (Total = LDL + HDL + Triglycerides/5). The AHA considers below 200 mg/dL desirable, 200-239 borderline, and 240+ high. However, total cholesterol is practically useless for accurate cardiovascular risk stratification without deeper fractionation. A high total driven by high HDL is protective, while the same number driven by high LDL is dangerous. Always request LDL, HDL, and ideally ApoB for the real picture.
| Range | Values |
|---|---|
| Standard Reference | 125–200 mg/dL |
| Optimal | 125–200 mg/dL |
| Longevity Optimal | < 200 mg/dL |
| High Risk | > 240 mg/dL |
What causes abnormal Total Cholesterol levels?
High total cholesterol is commonly caused by a diet high in saturated and trans fats, sedentary lifestyle, obesity, smoking, genetics (familial hypercholesterolemia), hypothyroidism, diabetes, and certain medications. Age and sex also play a role — cholesterol tends to rise after menopause in women.
When should you see a doctor?
See your doctor if total cholesterol is above 240 mg/dL, or above 200 mg/dL with other risk factors (high blood pressure, diabetes, family history of heart disease, smoking). Always request a full lipid panel to see the LDL/HDL breakdown.
