In Australia, a total cholesterol level below 5.5 mmol/L is generally recommended for the general healthy population, but for those with risk factors like diabetes or heart disease, the target is lower, ideally below 4.0 mmol/L. These targets depend on your individual risk profile, so a doctor determines your specific goals, aiming for lower LDL ("bad") cholesterol and higher HDL ("good") cholesterol.
For the general healthy population, a total cholesterol of less than 5.5 mmol/L, LDL less than 2.0mmol/L and HDL of greater than 1.0 mmol/L is advised.
A total cholesterol level of 5.5 mmol/L is borderline high in many guidelines, considered the upper limit for the "healthy" range in the general population, but a target to aim below if you have risk factors like diabetes or heart disease, where <4.0 mmol/L is preferred. It's not immediately "high" but signals a need for monitoring and lifestyle review, as levels above 5.5 mmol/L are considered abnormal by some health bodies.
No, high cholesterol doesn't directly cause headaches, but it can lead to conditions like high blood pressure (hypertension) or atherosclerosis (plaque buildup) that do cause headaches by affecting blood flow to the brain, or sometimes stress/lifestyle factors causing both. While cholesterol itself is often asymptomatic, headaches or dizziness can be warning signs of underlying issues linked to high cholesterol, such as severely elevated blood pressure or poor circulation, so frequent headaches warrant a cholesterol check.
Children of all ages can be at risk of developing dangerous levels of cholesterol when excessive levels of LDL ("bad" cholesterol) or triglyceride accumulate in blood. High levels of LDL can deposit on the walls of blood vessels, creating plaque, which can lead to future health risks like heart disease.
Oatmeal, oat bran and high-fiber foods
Oatmeal has soluble fiber, which reduces your low-density lipoprotein (LDL) cholesterol, the "bad" cholesterol. Soluble fiber is also found in such foods as kidney beans, Brussels sprouts, apples and pears.
There are usually no symptoms of high cholesterol. But if left untreated, it can lead to heart attack and stroke. It's often a hidden risk factor which means it can happen without us knowing until it's too late.
Instead of saturated fats, switch to foods with healthier fats, such as lean meat, nuts, and unsaturated oils like canola, olive, and safflower oils. Limit foods with cholesterol. If you are trying to lower your cholesterol, you should have less than 200 mg a day of cholesterol.
Stress. Stress doesn't directly raise your cholesterol but it can lead to unhealthy ways of coping which can raise your cholesterol and your risk of heart disease. For example, you might want to eat unhealthy food such as pizza and takeaways, drink more alcohol or smoke. Stress can affect your health in other ways too.
Numbness and tingling: Yes. Narrowed arteries caused by high cholesterol can restrict blood flow to the arms, legs, hands, or feet, leading to these sensations. Joint pain: Indirectly. High cholesterol contributes to inflammation, which may worsen existing joint discomfort, especially in patients with arthritis.
Top 5 lifestyle changes to improve your cholesterol
Can exercise lower cholesterol? Yes, it can. Being active helps your body move the bad cholesterol (also known as non-HDL cholesterol) to your liver where it can be removed out of your system. You do not have to join a gym or go on long runs if you do not enjoy it, just start by moving more every day.
Low-density lipoprotein (LDL) is the "bad cholesterol" in terms of its potential for harming the heart and brain. It is a major contributor to arterial plaque development. Levels of LDL cholesterol higher than 130 milligrams per deciliter (mg/dL) are linked to an increased risk for ischemic stroke.
The TLC diet recommends limiting serving sizes or replacing foods high in saturated fat and cholesterol with healthier options. Fruits, vegetables, legumes (beans and lentils), nuts, whole grains, low- or non-fat dairy products, fish, poultry without the skin, and in moderate amounts, lean meats are good options.
The range below is an Australian guide for a healthy blood cholesterol level.
What are the worst foods for high cholesterol?
To remove cholesterol from your body, adopt a heart-healthy lifestyle by eating more soluble fiber (oats, beans, fruits) and healthy fats (olive oil, fish), exercising regularly (30 mins most days), losing excess weight, quitting smoking, and limiting alcohol, as these changes lower bad LDL cholesterol and raise good HDL cholesterol, with some people needing medication for more severe cases.
High cholesterol is often silent, but warning signs appear as plaque builds up, including chest pain (angina), shortness of breath, fatigue, numbness/coldness in limbs, dizziness, yellow fatty deposits (xanthomas), difficulty breathing, slurred speech, swelling in legs, or jaw/back pain (especially in women), often indicating a serious complication like a heart attack or stroke. A blood test (lipid profile) is the only way to know your levels.
Numbness or Weakness
Poor circulation can make your feet or lower legs feel unusually cold, even in warm weather. Cuts, sores, or bruises on your legs or feet may take longer to heal due to reduced blood supply. The skin on your legs may appear shiny, pale, or bluish. Hair loss on the legs and feet can also occur.
One would think that eating well and exercising should be enough to control cholesterol, but for some, it's not that simple. Genetics play a key role. If high cholesterol runs in your family, your body may not clear LDL cholesterol as well as it should.
Other medicines for high cholesterol
Other medicines may be used if statins do not work or you do not want to take statins. These include: other tablets – such as ezetimibe, fibrates, bile acid sequestrants (also called resins) and bempedoic acid. injections – such as alirocumab, evolocumab and inclisiran.
Eat less fatty food
To reduce your cholesterol, try to cut down on fatty food, especially food that contains a type of fat called saturated fat. You can still have foods that contain a healthier type of fat called unsaturated fat. Check labels on food to see what type of fat it has in it.
Choosing high-fiber snacks that contain heart-healthy unsaturated fats can help lower your cholesterol levels. Whole foods — in the form of fruits, vegetables, grains, and nuts — easily lend themselves to snack recipes whether you're at home or on-the-go.
For most healthy people, eating two eggs a day is generally not considered too much cholesterol, as research shows eggs have a minimal effect on blood cholesterol and saturated fat intake is a bigger factor, but those with heart conditions or Type 2 diabetes should consult a doctor and might need to limit intake to around seven eggs per week. The Dietary Guidelines for Americans no longer set a specific limit on dietary cholesterol, focusing instead on limiting saturated and trans fats, making eggs a nutritious part of a balanced diet when paired with healthy foods.
