In short
- HDL cholesterol is often called ‘good’ cholesterol because it helps transport excess cholesterol away from the bloodstream and back to the liver.
- A healthy HDL level is associated with maintaining healthy blood vessels and cardiovascular health.
- A low HDL level can be associated with an increased risk of cardiovascular disease.
- Factors such as physical activity, diet, smoking, body weight and genetics can influence HDL levels.
- An abnormal HDL level usually does not cause symptoms and is often discovered through blood testing.
- HDL cholesterol is usually measured together with LDL cholesterol and triglycerides as part of a lipid profile.
- A healthy lifestyle with regular physical activity and a varied diet can support healthy cholesterol levels.
- Would you like more insight into your cholesterol and cardiovascular health? An HDL test can provide valuable information.
What are lipoproteins?
Lipoproteins are small particles in your blood that transport fats, such as cholesterol, throughout your body. Because fats do not dissolve well in blood, these particles are needed to transport them to where they are needed. HDL is one of the best-known types of lipoprotein.
What role do lipoproteins play in the body?
Lipoproteins ensure that fats and cholesterol are transported to the right places in your body. Cholesterol, for example, is important for producing hormones and building cells. Without lipoproteins, these substances could not be transported effectively through your blood.
What is the difference between HDL and LDL?
HDL and LDL are two types of lipoproteins. HDL is often called ‘good cholesterol’ because it helps transport excess cholesterol from the blood vessels back to the liver. LDL is often called ‘bad cholesterol’ because it transports cholesterol to the tissues and can contribute to cholesterol build-up in the artery walls when levels are too high.
Why are lipoproteins measured?
Doctors measure lipoproteins such as HDL and LDL to help assess the risk of cardiovascular disease. A healthy balance of these values is important for the health of your heart and blood vessels. Measuring these levels can help identify potential risk factors at an early stage.
Which factors affect lipoproteins?
Various factors can affect your lipoprotein levels, including age, genetics, body weight, physical activity, smoking and certain medical conditions. Some medications can also change these levels.
Can diet affect lipoproteins?
Yes, your diet can affect your lipoprotein levels. Foods high in saturated and trans fats can increase LDL (‘bad’ cholesterol). Unsaturated fats, such as those found in nuts, fish and olive oil, can help maintain healthy cholesterol levels. Fibre-rich foods can also help support healthy cholesterol levels.
Are abnormal lipoprotein levels common?
Abnormal levels are relatively common, particularly among adults. Many people have high LDL or low HDL without noticing any symptoms. This is why it can be useful to have these values checked from time to time.
How can you support healthy lipoprotein levels?
You can take several steps to support healthy lipoprotein levels. Eat a balanced diet, exercise regularly, do not smoke and try to maintain a healthy weight. Medication may sometimes be necessary, but lifestyle changes can also have a positive effect. Discuss your individual situation with your doctor.
