High Blood Lipids
Everything you need to know about High Blood Lipids - symptoms, causes, treatment options available in Australia, and when to see a doctor. Evidence-based medical information.
What You Need to Know - The Basics
High blood lipids mean there's too much fat in your blood.
The main things to know:
- You usually don't feel sick, but it can cause problems later.
- It often affects older people or those who eat unhealthy foods.
- It can lead to heart disease but is treatable with lifestyle changes and medicine.
- Having high blood lipids is like having too much fat in your blood, which can clog your arteries over time.
When to see a doctor immediately: If you experience chest pain, trouble breathing, or sudden weakness in your arms or legs.
Doctors can help you manage high blood lipids with simple changes and treatments.
Overview
This condition is a medical condition that affects your body in specific ways.
How it works in your body (pathophysiology):
High blood lipids, also called dyslipidaemia, affect your body in several ways:
- Abnormal lipid levels: This condition causes unusual levels of lipids (fats) in your blood, such as cholesterol and triglycerides (a type of fat).
- Lipoprotein transport: Lipids move through your blood attached to proteins called lipoproteins. When these are out of balance, problems can occur.
- Plaque formation: Imbalances can lead to atherosclerosis, where plaques (fatty deposits) form on the walls of your arteries. This can increase the risk of heart attacks or strokes.
- Influencing factors: Genetic predispositions (inherited traits), lifestyle choices, and metabolic processes all play a role in how high blood lipids develop.
Statistics and Prevalence in Australia
Did you know? About 2022 of Australians are affected by this condition.
In Australia, high blood lipids are a prevalent health concern.
Between 2022 and 2024, approximately 58.9% of Australian adults aged 18 years and over were reported to have dyslipidaemia, either through abnormal lipid measures or the use of lipid-lowering medication [1].
The condition is more common in males (61.1%) compared to females (56.9%) [1].
The how common it is of self-reported high cholesterol increases with age, affecting 1.1% of those aged 18–34, rising to 29.0% in those aged 75 and over [3], [4].
Symptoms and Clinical Presentation
This condition can show up in different ways, and symptoms may vary between people.
Common symptoms:
- Symptoms can be mild at first but may get worse over time
- Each person may experience different combinations of symptoms
- Symptoms can come and go or be constant
Early warning signs:
- Subtle changes that may be the first signs of the condition
- Symptoms that might be easy to miss or ignore
Serious warning signs that need immediate medical attention:
- Severe symptoms that could indicate complications
- Any symptoms that get suddenly worse
- Signs that suggest you need urgent medical care
Important: If you're unsure about your symptoms, it's always better to see a doctor for proper evaluation.
High blood lipids often present without symptoms, making regular screening crucial for early detection.
However, advanced dyslipidaemia can lead to symptoms related to cardiovascular complications, such as chest pain, shortness of breath, or even heart attacks.
Red flag symptoms that require immediate medical attention include sudden chest pain, severe headaches, or unexplained fatigue [5].
In some cases, physical signs such as xanthomas (fatty deposits under the skin) may be observed [6].
Causes and Risk Factors
This condition happens for several reasons working together. It's important to understand that having risk factors doesn't mean you'll definitely develop the condition.
Main causes:
- The exact cause may not be fully understood
- Multiple factors usually work together
- Both genetic and environmental factors can play a role
Risk factors you can't change:
- Your age and gender
- Family history and genetics
- Previous medical conditions
Risk factors you can influence:
- Lifestyle choices
- Environmental exposures
- Health management decisions
Good news: Understanding these risk factors can help with prevention and early detection.
The causes of high blood lipids are has many causes, involving both genetic and environmental factors.
Genetic conditions such as familial hypercholesterolaemia can lead to elevated lipid levels from a young age [5].
Lifestyle factors, including a diet high in saturated fats, lack of physical activity, and smoking, significantly contribute to dyslipidaemia.
Additionally, conditions such as obesity, diabetes, and hypothyroidism can make worse lipid imbalances [6].
Diagnosis
Getting the right diagnosis is important for proper treatment. Australian doctors follow specific guidelines to ensure accurate diagnosis.
How doctors diagnose this condition:
- They ask detailed questions about your symptoms and medical history
- They do a physical examination
- They may order specific tests if needed
- They use established medical guidelines and criteria
Tests that might be needed:
- Blood tests to check for specific markers
- Imaging studies like X-rays or scans if appropriate
- Specialist tests depending on your symptoms
Why accurate diagnosis matters: The sooner doctors can diagnose the condition correctly, the faster they can start the right treatment for you.
The diagnosis of high blood lipids in Australia follows guidelines set by the Royal Australian College of General Practitioners (RACGP) and the National Health and Medical Research Council (NHMRC).
The Australian CVD Risk Calculator is utilised to estimate the 5-year risk of a cardiovascular event, guiding the frequency of lipid testing [6].
Laboratory tests include measuring total cholesterol, LDL, HDL, and triglycerides.
For those at high risk, more frequent testing and complete lipid profiling are recommended [7].
Treatment Options in Australia
Treatment for this condition in Australia follows evidence-based guidelines and is tailored to each person's needs.
Treatment approaches available:
- First-line treatments: Usually tried first and often most effective
- Medications: Various medicines that can help manage symptoms
- Non-medicine treatments: Therapies and lifestyle changes that can help
- Specialist treatments: More advanced options for complex cases
Good news about costs in Australia:
- Medicare covers many consultations and treatments
- The Pharmaceutical Benefits Scheme (PBS) makes many medications more affordable
- Public healthcare provides access to essential treatments
Treatment planning: Your healthcare team will work with you to create a treatment plan that suits your specific needs and circumstances.
Treatment for high blood lipids involves a combination of lifestyle modifications and medicine interventions.
First-line treatment includes dietary changes, such as reducing saturated fat intake and increasing fibre consumption, alongside regular physical activity [6].
medicine treatments often involve statins, which are effective in lowering LDL cholesterol levels.
Other medications, such as ezetimibe or PCSK9 inhibitors, may be used in cases where statins are insufficient or not tolerated [7].
The Pharmaceutical Benefits Scheme (PBS) in Australia provides subsidies for many lipid-lowering medications, making them accessible to a broader population [6].
Living with High Blood Lipids
Managing this condition is an ongoing process, but many people learn to live well with proper support and care.
Daily management:
- Follow your treatment plan as prescribed
- Keep track of your symptoms and how you're feeling

Important: With proper management and support, many people with this condition live full and active lives.
Managing high blood lipids requires ongoing keeping track and lifestyle adjustments.
Regular follow-up appointments with healthcare providers are essential to assess treatment how well it works and make necessary adjustments.
Patient education on self-management strategies, including dietary choices and exercise routines, is crucial for long-term health optimisation [6].
Psychosocial support may also be beneficial, particularly for individuals struggling with lifestyle changes or medication following [7].

- Get adequate sleep
- Stay up to date with vaccinations and health screenings
Preventing high blood lipids involves adopting a heart-healthy lifestyle.
This includes maintaining a balanced diet rich in fruits, vegetables, and whole grains, engaging in regular physical activity, and avoiding tobacco use.
Regular health screenings are vital for early detection and management of lipid abnormalities, particularly for individuals with a family history of dyslipidaemia or cardiovascular disease [6].
Public health initiatives in Australia continue to promote awareness and education on the importance of cardiovascular health and risk factor management [7].
