High cholesterol is a major health concern in Australia, and it is important to understand what a good cholesterol reading is. Cholesterol is a type of fat produced by the liver and most body cells, and it is transported through the body via the lipoproteins in the bloodstream. High-density lipoprotein (HDL) cholesterol is known as 'good' cholesterol, as it helps remove excess cholesterol from the body's cells, including those in the arteries, reducing the risk of heart disease. Ideally, HDL levels should be above 60. On the other hand, low-density lipoprotein (LDL) cholesterol is considered 'bad' as it can lead to fatty deposits in the arteries, increasing the risk of cardiovascular disease. LDL levels should be kept below 100. Total cholesterol levels should ideally be below 200, with the specific target depending on individual risk factors.
| Characteristics | Values |
|---|---|
| Total cholesterol | Less than 5.5 mmol/L |
| LDL cholesterol | Less than 2.0 mmol/L |
| HDL cholesterol | Greater than 1.0 mmol/L |
| Triglycerides | Less than 2.0 mmol/L |
| Ideal HDL level | Above 60 |
| Ideal LDL level | Below 100 |
| Ideal total cholesterol level | Below 200 |

What You'll Learn
HDL cholesterol should be above 60
HDL cholesterol, or high-density lipoprotein, is often referred to as 'good' cholesterol. This is because HDL helps to reduce the risk of heart disease by clearing excess cholesterol from the arteries and carrying it back to the liver for processing. The higher the level of HDL cholesterol, the lower the risk of heart disease.
HDL cholesterol levels lower than 40 mg/dL are considered concerning, whereas levels above 60 mg/dL are considered excellent. For men, the benefits of HDL cholesterol extend to 90 mg/dL, after which no further benefits have been observed.
In Australia, people being treated for high cholesterol should ideally maintain HDL levels of 1.0 mmol/L or above. This is because HDL cholesterol is protective against cardiovascular disease, including heart attacks.
It is important to note that HDL levels can be increased by engaging in moderate-intensity exercise three to four times a week, eating heart-healthy foods, and maintaining a healthy weight. However, if your HDL levels are too high, it is recommended to consult a healthcare provider to identify the cause and determine if treatment is necessary.

LDL cholesterol should be below 100
LDL cholesterol, or low-density lipoprotein, is considered "bad" cholesterol. This is because high levels of LDL cholesterol can lead to a buildup of cholesterol in your arteries, causing health problems. This condition is called atherosclerosis and can lead to cardiovascular disease, heart disease, and stroke.
Australian guidelines recommend that people who need treatment for high cholesterol should aim for LDL levels lower than 2.0 mmol/L. However, for those at high risk, such as those with a history of heart attack or atherosclerosis, LDL levels should be less than 1.8 mmol/L or even below 70 mg/dL, respectively.
Most adults should strive to maintain their LDL cholesterol below 100 milligrams per deciliter (mg/dL). Levels above this threshold increase the risk of cardiovascular disease, including heart and blood vessel problems. Therefore, healthcare providers often encourage higher levels of HDL ("good") cholesterol and lower LDL levels to mitigate this risk.
Lifestyle changes, such as a healthy diet and regular physical exercise, are crucial in managing LDL cholesterol levels. Heart-healthy eating plans typically involve limiting saturated and trans fats, which are commonly found in fatty meats, full-fat dairy, baked goods, and fast food. Maintaining a healthy weight is also important, as being overweight can contribute to elevated LDL levels. Additionally, tobacco use should be avoided, as it lowers HDL cholesterol, which is responsible for removing excess LDL cholesterol from the body.
In some cases, cholesterol-lowering medications may be necessary to reduce the risk of cardiovascular disease and related issues. It is important to consult with a healthcare professional to determine the appropriate course of action based on individual risk factors and health status.

Total cholesterol should be below 200
Total cholesterol levels are an important indicator of health. While cholesterol is essential for the body and produced by the liver, high cholesterol levels can lead to health issues. For total cholesterol, a reading below 200 is considered a good result.
Cholesterol is a type of lipid or fat that circulates in the blood. It is carried by lipoproteins, which come in two types: high-density lipoprotein (HDL) and low-density lipoprotein (LDL). HDL is known as 'good' cholesterol as it helps to remove excess cholesterol from the body's cells, including those in the arteries, and transports it to the liver for processing. On the other hand, LDL is considered 'bad' cholesterol as it can build up in the blood and form fatty deposits or plaque on the lining of arteries, causing them to harden and narrow. This condition is called atherosclerosis, which can lead to cardiovascular disease, heart attacks, and strokes.
High cholesterol is a major health concern in Australia, and it is important to manage it to reduce the risk of these serious health issues. While normal cholesterol levels vary based on age, ethnicity, and sex, a total cholesterol level below 5.5 mmol/L is generally recommended for the healthy population. However, for those with cardiovascular risk factors such as high blood pressure, pre-existing heart disease, diabetes, or smoking, a lower LDL target of less than 2.0 mmol/L is advised.
To manage cholesterol levels, a healthy lifestyle that combines a nutritious diet with regular physical exercise is crucial. Eating foods that contain HDL cholesterol and avoiding those high in LDL cholesterol can help lower LDL levels. Additionally, cholesterol-lowering medications may be prescribed in some cases to reduce the risk of heart attack. Regular cholesterol checks, especially from the age of 45, are important to monitor levels and make any necessary adjustments to maintain good health.

High cholesterol has no symptoms
In Australia, a total cholesterol level of less than 5.5 mmol/L is recommended for the general healthy population, while those at high risk for chronic diseases are advised to maintain levels below 4.0 mmol/L. LDL ("bad" cholesterol) should be kept under control, with levels below 2.0 mmol/L for the general population and below 1.8 mmol/L for those at high risk. HDL ("good" cholesterol) should ideally be above 1.0 mmol/L.
High cholesterol is a common health issue, with nearly 94 million Americans aged 20 or older having borderline high cholesterol levels. However, it often goes undetected as it typically presents without symptoms. Many people are unaware of their high cholesterol until they visit a doctor for other reasons. This lack of symptoms makes high cholesterol a "silent killer", and it is crucial to proactively manage this condition through regular check-ups and lifestyle changes.
High cholesterol itself may not cause immediate symptoms, but it can lead to serious health complications over time. It is associated with an increased risk of peripheral artery disease, high blood pressure, heart disease, and stroke. The accumulation of fatty deposits (plaque) in the arteries due to high LDL cholesterol can cause blockages, resulting in cardiovascular issues. High cholesterol can also be a consequence of other diseases, particularly those that trigger inflammation, such as lupus.
While high cholesterol may not exhibit noticeable symptoms, certain rare disorders can cause physical symptoms like lesions or cholesterol deposits under the skin or eyelids. Additionally, high cholesterol can be a genetic condition, but it is also influenced by lifestyle factors such as diet and physical activity. To manage high cholesterol, it is essential to make healthy dietary choices, reduce saturated and trans fats, and incorporate regular aerobic exercise into your routine. In some cases, cholesterol-lowering medications may be necessary to reduce the risk of heart attack.
It is important to note that high cholesterol can be managed and prevented through a combination of lifestyle changes and medical interventions. By maintaining a healthy diet, exercising regularly, and seeking medical advice, individuals can effectively control their cholesterol levels and reduce the risk of associated health complications.

High cholesterol is a major health concern in Australia
There are two main types of cholesterol: high-density lipoprotein (HDL) and low-density lipoprotein (LDL). HDL cholesterol is often referred to as "'good'" cholesterol because it helps to remove excess cholesterol from the body's cells, including the cells in the arteries. It also carries cholesterol away from the arteries back to the liver for processing. On the other hand, LDL cholesterol is considered '"bad"' cholesterol because it tends to linger in the blood and can lead to fatty deposits in the arteries, causing them to harden and narrow. This can make it difficult for organs to get the blood and oxygen they need, increasing the risk of cardiovascular disease, heart attacks, and strokes.
Australian guidelines recommend that people with high cholesterol aim for an LDL level of less than 2.0 mmol/L, while those at high risk, such as those who have had a heart attack, should aim for an LDL level of less than 1.8 mmol/L. For HDL cholesterol, a level of 1.0 mmol/L or higher is considered protective against cardiovascular disease. Triglycerides, another type of fat found in the bloodstream, can also contribute to the development of atherosclerosis, or hardening and narrowing of the arteries. Australians being treated for cholesterol should generally aim for triglyceride levels of less than 2.0 mmol/L.
It is important to note that cholesterol levels vary from person to person and can be influenced by various factors such as age, ethnicity, sex, diet, and physical activity levels. Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can help lower cholesterol levels and reduce the risk of associated health problems. In some cases, cholesterol-lowering medication may also be necessary to manage high cholesterol and reduce the risk of heart disease.
