Dyslipidemia / cholesterol
Dyslipidemia means abnormal LDL ("bad") cholesterol, HDL ("good") cholesterol, or triglyceride levels, which raise cardiovascular risk — especially alongside diabetes. It's identified with a simple blood test, and current guidelines specifically recognize South Asian ancestry as an independent risk-enhancing factor for premature heart disease, which shapes how aggressively it's treated even when a standard risk calculator alone might suggest a lower priority.
How we assess and manage your lipids
Lipid Panel Blood Test
LDL, HDL, triglycerides, and total cholesterol — fasting or non-fasting, depending on the situation.
Calculating Your Cardiovascular Risk
Using a validated risk calculator alongside your personal history.
Checking Risk-Enhancing Factors
Including a one-time lipoprotein(a) test, family history, and other markers that refine your risk beyond the calculator alone.
Setting Your Personal LDL Target
Individualized to your overall risk category, not a single number for everyone.
Starting or Adjusting Treatment
Lifestyle measures and medication where indicated, matched to your target.
Follow-Up Testing
Confirming you're at target and adjusting the plan as needed.
Symptoms
- Usually no symptoms — detected through blood testing
- In rare, severe cases, visible fatty deposits under the skin or around the eyes
Causes & risk factors
- Insulin resistance and diabetes
- Diet and physical inactivity
- A family history of high cholesterol
- Excess weight
Nationally, dyslipidemia affects an estimated 81.2% of Indian adults (ICMR-INDIAB national study (Anjana et al., Lancet Diabetes & Endocrinology, 2023)).
Understanding your lipid panel
A standard lipid panel measures a few distinct markers, each interpreted alongside the others rather than in isolation.
| Marker | What it measures | General target |
|---|---|---|
| LDL cholesterol | "Bad" cholesterol that contributes to arterial plaque | Individualized to your risk category — see below |
| HDL cholesterol | "Good" cholesterol that helps clear excess cholesterol | Higher is generally favorable, though it isn't a treatment target itself |
| Triglycerides | A type of fat in the blood, linked to diet, weight, and glucose control | Below 150 mg/dL; higher levels are addressed directly |
| Non-HDL cholesterol / apoB | A broader measure of all cholesterol-carrying particles linked to risk | Used for further risk refinement in specific situations — see below |
The blood test
A single blood draw measures LDL, HDL, triglycerides, and total cholesterol together
What it predicts
These markers estimate your risk of atherosclerosis — plaque buildup in your arteries
Your heart
The end goal of managing these markers is reducing your risk of heart attack and stroke
Why South Asian ancestry matters for your risk
This is one of the more significant updates in current cholesterol guidelines, and directly relevant to most patients at this practice.
An independent risk factor, not just a prevalence statistic
- The 2026 ACC/AHA/Multisociety dyslipidemia guideline explicitly names South Asian ancestry as a risk-enhancing factor, reflecting higher rates of premature cardiovascular disease in South Asian populations
- This is separate from lipoprotein(a) levels — South Asian populations actually average a lower Lp(a) level than some other groups, but ancestry itself is still counted as an independent risk-enhancer
- In practice, this means treatment may be reasonably more intensive than a generic risk calculator alone would suggest, once this factor is added to your personal risk assessment
Lipoprotein(a): a one-time test worth having
Lipoprotein(a), or Lp(a), is a cholesterol-carrying particle that's largely determined by genetics rather than diet or lifestyle — which is part of why it's tested differently from the rest of your lipid panel.
For the first time, current guidelines recommend that every adult have Lp(a) measured at least once — not repeated routinely, since it tends to stay stable over your lifetime. A high result (roughly 50 mg/dL or higher) is treated as a risk-enhancing factor that can shift your LDL target and treatment intensity, even if the rest of your lipid panel looks otherwise unremarkable.
Setting your LDL target
There's no single "normal" LDL number — your target depends on your overall risk category, which is why the same LDL result can mean different things for different people.
- Risk-enhancing factors — including South Asian ancestry and elevated Lp(a) — can shift you toward a more intensive target within these categories
| Risk category | LDL-C target |
|---|---|
| Very-high-risk clinical cardiovascular disease | Below 55 mg/dL |
| Other clinical cardiovascular disease, or high-risk primary prevention (e.g., familial hypercholesterolemia, multiple risk factors) | Below 70 mg/dL |
| Diabetes, generally | Below 100 mg/dL, intensified to below 70 mg/dL with additional risk factors |
How dyslipidemia is treated
Statins remain the first-line, foundational treatment, with the specific intensity matched to your risk category rather than a fixed dose for everyone.
- Statins (such as atorvastatin or rosuvastatin) are prescribed at low, moderate, or high intensity depending on your target and risk
- Ezetimibe can be added when a statin alone doesn't reach your target
- PCSK9 inhibitors are considered for very-high-risk patients who need further LDL lowering beyond statins and ezetimibe
- Icosapent ethyl can be considered as an add-on specifically for persistently high triglycerides, to further reduce cardiovascular risk
- Molecule names are used here first; specific brand selection is discussed individually and noted for recognition only, not as an endorsement of any manufacturer
Follow-up and monitoring
Your lipid panel is typically rechecked a few weeks to months after starting or adjusting treatment to confirm you're moving toward your target, then monitored periodically after that — the exact schedule is individualized to your risk category and how your levels respond.
How it’s diagnosed
Diagnosis is by a fasting or non-fasting lipid panel blood test, interpreted alongside your overall cardiovascular risk profile and risk-enhancing factors such as a one-time lipoprotein(a) test.
How it’s treated
Management combines dietary and lifestyle measures with medication (such as statins) where indicated, with LDL targets individualized to your risk category — including diabetes status, South Asian ancestry, and other risk-enhancing factors — rather than a single target for everyone.
When to seek care
- You haven't had a lipid panel checked recently, particularly if you have diabetes or a family history of heart disease
- Chest pain or symptoms of a cardiovascular event — seek emergency care
- New muscle pain or weakness after starting a statin
- Sudden weakness, facial drooping, or difficulty speaking — signs of a possible stroke, requiring emergency care
FAQ
Is high cholesterol always related to diet?
Diet is one factor, but genetics, insulin resistance, and other conditions also strongly influence cholesterol levels — which is why testing and individualized treatment matter more than diet alone.
What do LDL, HDL, and triglycerides each measure?
LDL ("bad" cholesterol) contributes to arterial plaque; HDL ("good" cholesterol) helps clear excess cholesterol; triglycerides are a type of blood fat linked to diet, weight, and glucose control. All three are interpreted together, not individually.
What is a healthy LDL target for me?
This depends on your overall risk category — as low as below 55 mg/dL for very-high-risk cardiovascular disease, below 70 mg/dL for other high-risk situations, or below 100 mg/dL (intensified to below 70 with added risk factors) generally in diabetes.
Why is my LDL target different from a family member's?
Targets are individualized to overall cardiovascular risk, not a single number for everyone — factors like existing heart disease, diabetes, South Asian ancestry, and lipoprotein(a) levels all shape your specific target.
What is lipoprotein(a), and why is it tested?
Lipoprotein(a), or Lp(a), is a largely genetically determined cholesterol-carrying particle. Current guidelines recommend every adult have it measured at least once, since a high result is a risk-enhancing factor that can shift your treatment target.
Can lipoprotein(a) be lowered with diet or lifestyle changes?
Not substantially — Lp(a) is largely genetically determined. Instead of trying to lower it directly, a high result is used to guide more intensive management of your other, modifiable risk factors.
Why is South Asian ancestry mentioned as a cholesterol-related risk factor?
Current cholesterol guidelines specifically name South Asian ancestry as an independent risk-enhancing factor, reflecting higher rates of premature cardiovascular disease in South Asian populations — separate from, and in addition to, your individual lipid numbers.
What is apoB, and do I need it tested?
ApoB is a marker reflecting the total number of cholesterol-carrying particles in your blood. It's useful for further risk refinement in specific situations — for example, high triglycerides, diabetes, or when LDL is already at target but risk remains uncertain.
Do I need to fast before a lipid test?
Not always — both fasting and non-fasting lipid panels are acceptable in many situations. Your care team will let you know if fasting is specifically needed for your particular test.
Are statins safe for long-term use?
Yes, for most patients — statins are the best-studied, foundational treatment for dyslipidemia, with an extensive long-term safety record. Any specific concerns are discussed individually with your care team.
What if I can't tolerate a statin?
Several options exist — adjusting the dose or specific statin, or adding or switching to non-statin medicines such as ezetimibe or, for very-high-risk patients, a PCSK9 inhibitor.
Do I need medication if my diet is already healthy?
Possibly — cholesterol levels are influenced by genetics and other factors beyond diet, so some patients need medication despite excellent lifestyle habits, particularly if their overall cardiovascular risk is high.
How often should cholesterol be tested?
This depends on your risk category and whether you're on treatment — more frequently after starting or adjusting medication, less frequently once you're stable at target. Your care team will advise on timing suited to you.
Does high cholesterol cause any symptoms?
Usually not — it's identified through blood testing rather than symptoms, which is exactly why regular testing matters rather than waiting to feel unwell.
Is high cholesterol the same as heart disease?
No — dyslipidemia is a risk factor that contributes to cardiovascular disease over time, not the disease itself. Managing it is aimed at reducing that future risk.
