A total cholesterol level of 7.5 mmol/L is considered very high and a significant risk factor for cardiovascular disease (CVD), warranting urgent medical attention as it often points to genetic conditions like Familial Hypercholesterolemia (FH) or severe lifestyle issues, increasing chances of heart attack and stroke. It's well above the desirable Australian target of <5.5 mmol/L, signaling potential plaque buildup (atherosclerosis) in arteries, requiring investigation into LDL/HDL levels and lifestyle changes, notes the Royal Australian College of General Practitioners (RACGP), Genomics Education Programme, Australian Institute of Health and Welfare (AIHW), HIF Health Hub, Victor Chang Cardiac Research Institute, healthdirect, and Heart Research Institute.
However, it's not just about one number. Your doctor will look at your total cholesterol level, too. A cholesterol reading above 240 mg/dL is considered high and potentially dangerous. Think of it as a waving red flag, signaling it's time to take action.
Top 5 lifestyle changes to improve your cholesterol
Three main factors contribute to high cholesterol in children and teens: An unhealthy diet, especially one that is high in saturated fats. A family history of high cholesterol, especially when one or both parents have high cholesterol. Having obesity.
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.
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.
Statins. Statins are the most common medicine for high cholesterol. They reduce the amount of cholesterol your body makes. You take a tablet once a day.
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.
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.
Age. Even young children can have high cholesterol. But it's much more common in people over 40. As you age, your liver becomes less able to remove "bad" LDL cholesterol.
Elevated cholesterol (total cholesterol of more than 7.5mmol/L and LDL of more than 4.9mmol/L) raises the possibility of a genetic cause – namely, familial hypercholesterolaemia (FH). FH confers a significant risk of premature CVD. For men, the risk is 50% by the age of 50. For women, the risk is 30% by the age of 60.
If your risk is very low, you probably won't need a statin, unless your LDL is above 190 mg/dL (4.92 mmol/L ). If your risk is very high — for example, you've had a heart attack in the past — a statin may be helpful even if you don't have 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.
Levels of LDL cholesterol higher than 130 milligrams per deciliter (mg/dL) are linked to an increased risk for ischemic stroke.
Both polyunsaturated and monounsaturated fatty acids help lower LDL. Most plant-derived oils, including canola, safflower, sunflower, olive, grapeseed, and peanut oils, contain both. Fatty fish (such as salmon, tuna, trout, herring, and mackerel), seeds, nuts, avocados and soybeans are also great sources.
When a plaque of cholesterol ruptures and a clot covers it, it closes off an entire artery. This is a heart attack, and the symptoms include severe chest pain, flushing, nausea and difficulty breathing. This is a medical emergency.
Give cheese on toast a miss and instead use sliced or mashed avocado to top wholegrain toast or crumpets. This quick snack is rich in unsaturated, rather than saturated, fats. Try a sprinkle of seeds or chilli flakes for an extra kick. Read more from our dietitian about avocados and fat.
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.
To be sure that Weet-Bix™ Cholesterol Lowering is as effective as all the science around plant sterols, Sanitarium ran a trial with Professor Peter Clifton, Professor of Nutrition at the University of South Australia. This trial showed that cholesterol was effectively reduced by up to 9% within 4 weeks.
High cholesterol doesn't just affect your heart—it can show up on your face in subtle yet significant ways. From yellowish patches around your eyes to small cholesterol bumps, these signs are your body's way of warning you about elevated cholesterol levels.
Think brisk walking, jogging, cycling, swimming or dancing. Aerobic workouts get your heart pumping and help lower LDL while increasing HDL. Aim for: At least 150 minutes per week of moderate-intensity aerobic activity (like walking fast enough to break a light sweat), or.
Nail changes can show signs of heart problems. It's important to watch for these signs to keep your heart healthy. This helps catch heart issues early. Look out for nail changes like clubbing, splinter hemorrhages, and cyanotic nail beds.
Statins block an enzyme the liver needs to make cholesterol. This causes the liver to remove cholesterol from the blood. While statins are effective and safe for most people, they have been linked to muscle pain, digestive problems, and mental fuzziness in some people. Rarely, they may cause liver damage.
High Levels: A level of 6.5 mmol/L or above is classified as high and may increase your risk of cardiovascular disease.
Limit your cholesterol intake to less than 200 mg per day. Limit egg yolks to 2–3 a week. Choose egg white and egg substitutes — they don't have cholesterol. Avoid organ meats like liver and gizzards and fatty cuts of red meat (beef, pork, and lamb).
