We often hear, “Cholesterol bad hai!” But cholesterol itself isn’t the villain. In fact, your body needs this waxy, fat-like substance to build cell membranes and produce hormones and other essential substances.
The real concern is too much cholesterol circulating in the blood—particularly LDL cholesterol. Cholesterol travels through the bloodstream in particles called lipoproteins. LDL can contribute to plaque formation in artery walls when present at unhealthy levels. Over time, this plaque can narrow arteries and increase the risk of cardiovascular disease. HDL, often called “good cholesterol,” is involved in transporting cholesterol back toward the liver for processing, but cholesterol health is more complex than simply labelling LDL “bad” and HDL “good.”
What Causes High Cholesterol?
Lifestyle plays an important role, but it isn’t the whole story.
- A diet high in saturated and trans fats, frequent fried or highly processed foods.
- Physical inactivity
- Excess body weight
can negatively affect cholesterol and triglyceride levels.
- Smoking is another important cardiovascular risk factor.
- Age (>40 years), family history and genetics matter too.
- For women, LDL levels may also rise around and after menopause.
- Certain health conditions—including type 2 diabetes and chronic kidney disease—can also affect lipid levels.
- Certain medications and other medical conditions can influence cholesterol as well.
Why Should You Care?
The tricky part? High cholesterol usually doesn’t cause symptoms.
It can quietly contribute to atherosclerosis—the buildup of plaque in arteries.
- If arteries supplying the heart become affected, the risk of coronary heart disease and heart attack increases.
- If arteries supplying the brain are affected, it can contribute to ischemic stroke.
- Narrowed arteries in the limbs can cause peripheral artery disease.
Very high triglycerides are a different concern. Levels above 1,000 mg/dL are associated with a significantly increased risk of acute pancreatitis.
That’s why waiting for symptoms isn’t a good screening strategy.
Know Your Numbers—But Know the Context
A commonly used reference point is:
Total cholesterol: below 200 mg/dL
LDL: below 100 mg/dL is generally considered optimal
HDL: higher levels are generally associated with lower cardiovascular risk
Triglycerides: below 150 mg/dL
However, there is no single “perfect” cholesterol number for everyone. LDL targets depend on your overall cardiovascular risk and whether you already have conditions such as cardiovascular disease.
What Can You Do?
Start with the basics:
- Choose more vegetables, fruits, whole grains, pulses and fibre-rich foods.
- Prefer unsaturated fats over saturated and trans fats.
- Aim for regular physical activity—around 150 minutes of moderate activity per week is a useful general target.
- Avoid smoking and tobacco exposure.
- Work toward a healthy weight if needed.
- Manage diabetes and blood pressure.
- Get your lipid profile checked as advised, particularly if you have risk factors or a family history.
And sometimes lifestyle changes aren’t enough. For people at sufficiently high risk, medicines can substantially reduce cardiovascular risk. But medicines must be taken only when advised by the physician.
The Bigger Picture
Cholesterol management isn’t simply about individual choices. Access to affordable nutritious food, safe places to exercise and regular preventive healthcare also shapes cardiovascular health.
So don’t fear your cholesterol report—and don’t ignore it either. Decode it, understand your risk, and take the next step that makes sense for you.
