Understanding Your Cholesterol Numbers
Cholesterol is often discussed as though it were simply good or bad. In reality, a lipid profile is a set of related measurements, and what matters is the overall pattern interpreted alongside your other risk factors.
What the numbers mean
LDL cholesterol is the fraction most directly associated with plaque build-up in artery walls. Lowering it reduces cardiovascular risk.
HDL cholesterol helps transport cholesterol away from the arteries; higher levels are generally favourable. Triglycerides are another form of fat in the blood, often raised alongside diabetes, excess weight and high alcohol intake. Total cholesterol is the overall figure, and is less informative on its own than the individual components.
Why targets differ between people
There is no single correct LDL level for everyone. The appropriate target depends on overall cardiovascular risk. Someone who has had a heart attack, or who has diabetes, is generally advised to reach a lower level than someone at low risk.
This is why comparing your report with someone else's is rarely meaningful.
What raises cholesterol
Diet contributes, but so do genetics, physical inactivity, excess weight, diabetes, thyroid disorders and some medications. Some people have familial hypercholesterolaemia, an inherited condition producing very high levels from a young age, which warrants specific attention and family screening.
What lowers it
Dietary change — reducing saturated fat, fried and processed foods, and increasing fibre — together with regular activity and weight management, forms the foundation.
Where risk is high, medication is often advised. Statins are the most established class. Concerns about long-term use are common and worth discussing openly with your doctor rather than resolving by stopping treatment.
Frequently asked questions
Do I need to fast before a lipid profile?
Fasting is not always required. Follow the instruction given with your test request, as practice varies.
Is high cholesterol always caused by diet?
No. Genetics, other medical conditions and inactivity all contribute. Some people with careful diets still have high levels.
Are statins safe long-term?
They are among the most extensively studied medications. Side effects occur in a minority and should be discussed rather than managed by stopping the medication independently.
Can exercise alone lower cholesterol?
Exercise improves the overall profile, particularly triglycerides and HDL. Whether it is sufficient alone depends on your starting levels and overall risk.
Have a question about your heart health?
Consultations with Dr. Ray are held at Fortis Hospital, Anandapur, Kolkata.
