Cholesterol Levels Explained: LDL, HDL, and Triglycerides in Plain Language
Cholesterol gets a bad reputation, but the reality is more nuanced. Your body needs cholesterol to build cell membranes, make hormones, and produce vitamin D. The problem is not cholesterol existing - it is when specific types build up in the wrong places.
Your lipid panel (also called a cholesterol test or fasting lipid profile) breaks this down into several measurements. This guide explains each one, what the Indian-specific targets are, and what a flagged value actually means for you.
What Is a Lipid Panel?
A lipid panel is a blood test that measures the fats (lipids) circulating in your blood. It is typically done after an overnight fast of 10-12 hours, because eating - particularly fatty foods - temporarily raises triglycerides and can affect other readings.
The standard lipid panel includes:
- Total Cholesterol
- LDL Cholesterol (often called "bad" cholesterol)
- HDL Cholesterol (often called "good" cholesterol)
- Triglycerides
- Non-HDL Cholesterol (calculated)
- VLDL (sometimes included)
Total Cholesterol
The sum of all cholesterol types in your blood. Used as a screening number, but not particularly useful on its own - what matters is how the components are distributed.
| Category | Total Cholesterol |
|---|---|
| Desirable | Below 200 mg/dL |
| Borderline high | 200 - 239 mg/dL |
| High | 240 mg/dL and above |
Someone with a total cholesterol of 220 mg/dL but high HDL and low LDL may have a lower heart risk than someone with a total of 190 mg/dL but very low HDL. Always look at the full picture.
LDL Cholesterol - The One to Lower
LDL (Low-Density Lipoprotein) carries cholesterol from the liver to tissues around the body. When there is too much LDL, it deposits on artery walls and forms plaques - the process that leads to heart attacks and strokes over time.
Indian-specific note: Indians tend to develop cardiovascular disease at lower LDL levels and at younger ages compared to Western populations. This is why the targets recommended for Indians are often more conservative.
| Category | LDL Cholesterol |
|---|---|
| Optimal | Below 100 mg/dL |
| Near optimal | 100 - 129 mg/dL |
| Borderline high | 130 - 159 mg/dL |
| High | 160 - 189 mg/dL |
| Very high | 190 mg/dL and above |
For people with diabetes, existing heart disease, or a family history of early heart attacks, doctors often target LDL below 70 mg/dL.
High LDL causes: Diet high in saturated fats (ghee, butter, red meat, processed foods), genetic familial hypercholesterolaemia, hypothyroidism, or kidney disease.
HDL Cholesterol - The One to Raise
HDL (High-Density Lipoprotein) carries cholesterol away from artery walls and back to the liver for disposal. Higher HDL is protective - it acts as a scavenger, removing the dangerous deposits.
| Category | HDL Cholesterol |
|---|---|
| Low (risk factor) | Below 40 mg/dL (men), Below 50 mg/dL (women) |
| Acceptable | 40 - 59 mg/dL |
| Protective (desirable) | 60 mg/dL and above |
Indian-specific note: Low HDL is extremely common in Indians and is considered one of the primary metabolic risk factors in the South Asian population, even in people who are not overweight and whose other values look normal.
What raises HDL: Regular aerobic exercise (the most effective intervention), quitting smoking, moderate weight loss if overweight, and reducing refined carbohydrates. Alcohol raises HDL slightly, but this is not a recommended strategy.
Triglycerides
Triglycerides are the primary form in which fat is stored in your body and transported in your blood. They come from both dietary fat and excess carbohydrates - the liver converts unused sugars into triglycerides. This is why high triglycerides are closely linked to diets heavy in white rice, sugary drinks, sweets, and fruit juice - not just fatty food.
| Category | Triglycerides |
|---|---|
| Normal | Below 150 mg/dL |
| Borderline high | 150 - 199 mg/dL |
| High | 200 - 499 mg/dL |
| Very high | 500 mg/dL and above |
Indian-specific note: High triglycerides are strongly associated with insulin resistance and are a core component of metabolic syndrome - a cluster of conditions that significantly raises heart and diabetes risk.
What lowers triglycerides: Reducing refined carbohydrates and sugar (more effective than cutting fat), limiting alcohol, losing weight, and regular exercise. Omega-3 fatty acids (found in fish, or as supplements) can also meaningfully lower very high triglyceride levels.
Non-HDL Cholesterol
Calculated as Total Cholesterol minus HDL. This captures all the "bad" cholesterol - LDL plus VLDL plus other atherogenic particles. Many cardiologists consider non-HDL a better predictor of heart risk than LDL alone.
| Category | Non-HDL Cholesterol |
|---|---|
| Optimal | Below 130 mg/dL |
| Borderline high | 130 - 159 mg/dL |
| High | 160 mg/dL and above |
The Cholesterol Ratio
Some reports include the Total Cholesterol to HDL ratio, or LDL to HDL ratio. Lower is better.
- Total Cholesterol : HDL ratio - below 4.0 is desirable
- LDL : HDL ratio - below 3.0 is desirable
A person with total cholesterol of 220 but HDL of 70 has a ratio of 3.1 - actually quite good. A person with total cholesterol of 190 but HDL of 30 has a ratio of 6.3 - a concerning picture despite the "normal" total.
What Metabolic Syndrome Looks Like on a Lipid Panel
Metabolic syndrome - a very common condition in urban India - is diagnosed when three or more of these are present:
- Triglycerides above 150 mg/dL
- HDL below 40 (men) or 50 (women) mg/dL
- Blood pressure 130/85 or above
- Fasting blood sugar 100 mg/dL or above
- Abdominal obesity (waist above 90 cm in men, 80 cm in women for Indians)
If your lipid panel shows high triglycerides + low HDL, ask your doctor about a full metabolic screen.
Frequently Asked Questions
My LDL is high but I feel fine - do I still need to act? Yes. Cholesterol buildup in arteries happens silently over years, with no symptoms until a heart attack or stroke occurs. Addressing it early is exactly when it is most effective.
Can I lower cholesterol without medication? For borderline-high values, lifestyle changes alone - diet, exercise, weight loss - can meaningfully reduce LDL and triglycerides within 3-6 months. For very high LDL (above 190 mg/dL) or in people with existing heart disease, medication is usually needed alongside lifestyle changes.
Does eating ghee raise cholesterol? Ghee is high in saturated fat, which raises LDL in most people. Moderate amounts in an otherwise healthy diet are unlikely to be harmful, but large daily quantities will raise LDL over time. The bigger driver of high triglycerides in most Indians is excess refined carbohydrates, not ghee.
Should I fast before a cholesterol test? Yes - a 10-12 hour fast is recommended for an accurate triglyceride reading. LDL is often calculated using a formula that includes triglycerides, so a non-fasting sample can give a misleadingly higher LDL estimate.
