Quick answer. High LDL (“bad”) cholesterol is a major, usually symptom-free risk factor for heart attack and stroke, picked up through a simple blood test called a lipid panel. There is no single “safe” number for everyone: your LDL target is individualised based on your overall cardiovascular risk, so people with diabetes, existing heart disease or high risk aim for lower levels. Treatment starts with diet, exercise, weight and lifestyle changes, with statins added when needed; they are effective and generally safe. Inherited (familial) high cholesterol needs earlier, more intensive treatment, and outpatient costs are subsidised through the Chronic Disease Management Programme, with MediSave, CHAS and Healthier SG support.
High cholesterol is one of the most common health findings in Singapore, yet it rarely causes any symptoms – most people only learn about it from a routine blood test. Left unmanaged, raised “bad” cholesterol quietly builds up in the arteries over years and is a leading contributor to heart attacks and strokes. The good news is that it is highly treatable through a combination of lifestyle changes and, where needed, medication, with well-established subsidies for ongoing care.
At a glance
| Lipid | What it is | Why it matters |
|---|---|---|
| LDL cholesterol | "Bad" cholesterol that carries fat into artery walls | Main modifiable cause of heart attack and stroke; target is individualised by your overall cardiovascular risk |
| HDL cholesterol | "Good" cholesterol that helps clear fat from the blood | Higher levels are generally protective for the heart |
| Triglycerides | A fat carried in the blood, influenced by diet, alcohol and weight | Levels above 1.7 mmol/L raise heart risk; above 4.5 mmol/L can cause pancreatitis |
| Total cholesterol | The overall amount of cholesterol in the blood | Gives a general picture but is less precise than LDL for guiding treatment |
What cholesterol is: LDL, HDL and triglycerides
Cholesterol is a fatty substance your body needs to build cells and make hormones, but it is carried in the blood in different forms that matter very differently for your heart.
- LDL (low-density lipoprotein) – the “bad” cholesterol. LDL carries cholesterol into the artery walls, where it can build up as plaque. A high LDL is the main modifiable driver of coronary artery disease, heart attack and stroke.
- HDL (high-density lipoprotein) – the “good” cholesterol. HDL helps remove cholesterol from the bloodstream, so a higher HDL is generally protective.
- Triglycerides – a blood fat. Raised triglycerides (above 1.7 mmol/L) are associated with heart disease, and very high levels (above 4.5 mmol/L) can trigger acute pancreatitis.
Because high LDL almost never causes symptoms, screening is the only reliable way to know your numbers.
How it is measured – and why your target is individualised
Cholesterol is checked with a lipid panel (also called a lipid profile), a blood test that measures total cholesterol, LDL, HDL and triglycerides. Your doctor may advise fasting beforehand, particularly to interpret triglycerides accurately. Singapore primary-care protocols suggest reviewing the lipid profile regularly – commonly yearly – once you are being managed for a lipid disorder.
Crucially, there is no single LDL number that is right for everyone. Under Singapore’s ACE clinical guidance, LDL goals are personalised according to your overall 10-year cardiovascular risk, calculated using your age, blood pressure, smoking status, diabetes and other factors. People at higher risk – for example those with diabetes, chronic kidney disease, or established heart disease – are treated to lower LDL levels and often with more intensive therapy, while those at low risk may simply focus on lifestyle. Ask your doctor what your personal target is rather than relying on a one-size-fits-all figure.
Lifestyle changes come first
For everyone with raised cholesterol, lifestyle measures are the foundation of treatment and can meaningfully lower LDL:
- Cut saturated and trans fats – limit fatty and processed meats, deep-fried foods, coconut milk-rich dishes and palm-oil products.
- Eat more fibre and vegetables – wholegrains, fruit, vegetables, beans and oats help lower LDL.
- Move more – regular aerobic exercise improves your lipid profile and overall heart risk.
- Reach and keep a healthy weight.
- Limit alcohol and stop smoking – smoking lowers protective HDL and sharply raises cardiovascular risk.
These steps benefit your heart even when medication is also needed.
Statins and other cholesterol medication
When lifestyle alone is not enough, or your cardiovascular risk is high, medication is added. Statins are the first-line drug for most patients and are among the best-studied, most effective medicines for preventing heart attacks and strokes. Higher-intensity statin treatment aims to lower LDL by more than 50%.
Statins are generally safe and well tolerated. The most commonly raised concern is muscle aches; serious muscle problems are uncommon, and your doctor can monitor for side effects and adjust treatment if needed. Some patients have occasional blood tests to check liver and muscle markers. If a statin alone does not reach your target, ezetimibe may be added, and for very high-risk patients or familial hypercholesterolaemia, newer agents such as PCSK9 inhibitors or inclisiran may be considered. Cholesterol treatment is usually long term – do not stop on your own, as levels typically rise again.
Familial hypercholesterolaemia (inherited high cholesterol)
Familial hypercholesterolaemia (FH) is an inherited condition that causes very high LDL from birth, regardless of diet or lifestyle, and carries a high risk of premature heart disease. People with FH should not be assessed using the general population risk calculator and need earlier, more intensive lipid-lowering treatment. First-degree relatives of a diagnosed patient are recommended for screening. If you have a strong family history of early heart attacks or very high cholesterol, mention this to your doctor.
Costs, subsidies and when to see a doctor
High cholesterol (hyperlipidaemia / lipid disorders) is a covered condition under Singapore’s Chronic Disease Management Programme (CDMP), so outpatient management is supported by several schemes:
- MediSave can be used for outpatient chronic care – up to $500 per patient per year, or $700 for complex conditions, with a 15% cash co-payment.
- CHAS, Pioneer Generation and Merdeka Generation cardholders can receive subsidies on consultations and medications for chronic conditions.
- Healthier SG – enrolling with a GP clinic gives access to subsidised chronic medications comparable to polyclinic prices.
You should get screened if you are an adult who has not had a recent lipid test (often advised around every 3 years if results are normal, and more frequently if raised), and see a doctor sooner if you have diabetes, high blood pressure, a strong family history of early heart disease, or symptoms such as chest pain. Subsidies and exact eligibility can change, so confirm current details with your GP or polyclinic.
