Key takeaways

  • A lipid profile measures total cholesterol, LDL ('bad'), HDL ('good') and triglycerides.
  • For most adults, LDL below 100 mg/dL, HDL above 40 (men) or 50 (women) and triglycerides below 150 mg/dL are healthy.
  • Indians often have the 'atherogenic' pattern of high triglycerides and low HDL, which raises heart risk even when total cholesterol looks normal.
  • Fibre, regular activity, less refined carbohydrate and avoiding trans fats help; statins are recommended when your overall risk is high.

Cholesterol is a waxy fat your body needs to build cells and make hormones. Problems start when too much of the wrong kind circulates in your blood and builds up as plaque in your arteries: the process behind most heart attacks and strokes.

What a lipid profile measures

A lipid profile blood test usually reports four values:

  • LDL cholesterol: "bad" cholesterol that deposits in artery walls.
  • HDL cholesterol: "good" cholesterol that carries excess cholesterol back to the liver.
  • Triglycerides: fats that rise with sugar, refined carbohydrates and alcohol.
  • Total cholesterol: the sum of the cholesterol in all particles.

Some labs also report non HDL cholesterol (total minus HDL), which many cardiologists find more useful in Indians.

Healthy ranges for adults

Measure Desirable Borderline High
Total cholesterol Below 200 mg/dL 200 to 239 240 or higher
LDL cholesterol Below 100 mg/dL 130 to 159 160 or higher
HDL cholesterol 40+ (men), 50+ (women); 60+ is protective , Below 40 is low
Triglycerides Below 150 mg/dL 150 to 199 200 or higher

These are general ranges. If you have diabetes, heart disease or several risk factors, your doctor will set lower LDL targets, sometimes below 70 or even 55 mg/dL.

Why Indians face higher risk

South Asians tend to develop heart disease about 10 years earlier than other populations. A common pattern is high triglycerides with low HDL, driven by genetics, carbohydrate heavy diets, abdominal fat and inactivity. This means a "normal" total cholesterol can hide real risk: always look at the individual numbers.

How often to test

Adults should have a baseline lipid profile by their 20s or early 30s, then every few years if normal. Test earlier and more often if you have diabetes, high blood pressure, obesity or a family history of early heart attacks. A 9 to 12 hour fast is traditional, though many labs now accept nonfasting samples.

How to improve your cholesterol

Food

  • Eat more soluble fibre: oats, barley, rajma, chana, flaxseed, guava, apples.
  • Choose healthier fats: use a mix of oils (mustard, groundnut, rice bran) in moderation and add nuts and seeds.
  • Avoid trans fats: vanaspati and repeatedly reheated frying oil are major sources.
  • Cut refined carbohydrates and sugar, which push up triglycerides.
  • Curious about ghee? Read is ghee healthy?

Lifestyle

Regular aerobic exercise raises HDL and lowers triglycerides. Losing excess weight, quitting smoking and limiting alcohol all help.

Medicines

Statins (such as atorvastatin and rosuvastatin) are the main medicines for lowering LDL and are proven to reduce heart attacks and strokes. Others include ezetimibe and, for very high triglycerides, fenofibrate. Your doctor weighs your overall cardiovascular risk, not just one number, before prescribing.

The bottom line

Know your full lipid profile, not just total cholesterol. Small, steady changes in food and activity improve the numbers, and medicines add strong protection when your risk is high.
