Quick read
Key points
- 1
High cholesterol means there's too much of a fatty substance called cholesterol in your blood, which over time can build up in artery walls, increasing the risk of heart attack and stroke. It usually causes no symptoms, so it's typically identified through a routine blood test.
- 2
Use cardiovascular-risk assessment, lifestyle measures and evidence-based lipid-lowering treatment appropriately.
- 3
You haven't had your cholesterol checked and have risk factors, such as a family history
01 · Know
What is High Cholesterol?
High cholesterol means there's too much of a fatty substance called cholesterol in your blood, which over time can build up in artery walls, increasing the risk of heart attack and stroke. It usually causes no symptoms, so it's typically identified through a routine blood test.
High cholesterol is managed through a combination of dietary changes, physical activity, and, for many people, cholesterol-lowering medication (such as statins), significantly reducing the long-term risk of cardiovascular disease.
02 · Understand
Clinical context
Not all cholesterol is the same
Cholesterol tests measure different types, including LDL ("bad" cholesterol, linked to artery build-up) and HDL ("good" cholesterol, which helps protect against this) — understanding your specific results helps put your overall risk in context.
03 · Act
When to Seek Care
- 1You haven't had your cholesterol checked and have risk factors, such as a family history
- 2You've been diagnosed with high cholesterol and have questions about treatment
- 3You're considering starting or stopping cholesterol medication
- 4You'd like to discuss your overall cardiovascular risk
04 · Prevent & manage
Practical steps
Statins Are Generally Very Safe, Despite Some Common Misconceptions
While statins can occasionally cause side effects like muscle aches, serious side effects are rare, and for most people at meaningful cardiovascular risk, the benefits significantly outweigh the risks — discuss any concerns with your doctor rather than stopping treatment independently.
- 1Take prescribed cholesterol medication consistently.This significantly reduces cardiovascular risk for many people, even without causing noticeable symptoms.
- 2Adjust your diet to include less saturated fat.Choosing leaner proteins, more fibre, and healthy fats can help improve cholesterol levels.
- 3Stay physically active.Regular exercise can help raise protective HDL cholesterol and improve overall cardiovascular health.
- 4Stop smoking.This significantly improves cholesterol-related cardiovascular risk.
- 5Attend regular monitoring.This tracks how well your management plan is working over time.

BarnMD Bottom Line
High cholesterol is common and manageable, with medication and lifestyle changes together significantly reducing long-term cardiovascular risk.
Statins are generally very safe and effective for most people at meaningful risk — discuss any concerns with your doctor rather than stopping independently.
