Signs of high cholesterol are often difficult to notice because high cholesterol usually does not cause obvious symptoms. However, certain visible changes and complications may indicate an underlying health problem. Understanding the possible warning signs, recognising your risk factors, and getting a cholesterol blood test can help you take steps to protect your heart health.
Although there are no reliable everyday symptoms that confirm high cholesterol, certain visible changes may occur in people with very high cholesterol, especially those with an inherited condition. Understanding these warning signs and knowing when to get a cholesterol test can help protect your long-term heart health.
In this article, we explore six possible signs associated with high cholesterol, important risk factors, and practical steps to maintain healthy cholesterol levels.
What Is High Cholesterol?
Cholesterol is a waxy, fat-like substance that your body needs to build cells and produce certain hormones. However, having too much cholesterol in your blood can contribute to plaque buildup inside your arteries, a condition known as atherosclerosis.
There are two important types of cholesterol:
- LDL (low-density lipoprotein): Often called bad cholesterol because high levels can contribute to plaque buildup in the arteries.
- HDL (high-density lipoprotein): Often called good cholesterol because it helps transport cholesterol back to the liver.
Triglycerides are another type of fat in the blood. High triglycerides, particularly when combined with unhealthy cholesterol levels, can increase cardiovascular risk.
A lipid profile blood test measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides to help assess your heart health.
6 Signs You May Have High Cholesterol
1. Yellowish Bumps on the Skin
One possible sign of very high cholesterol is the development of yellowish fatty deposits beneath the skin, known as xanthomas.
These bumps may appear on the elbows, knees, hands, joints, ankles, or buttocks. Some deposits develop around tendons, including those near the hands and heels.
Xanthomas can be associated with inherited cholesterol disorders, such as familial hypercholesterolaemia. However, not every skin bump is caused by cholesterol.
What to do: If you notice unusual yellowish lumps, consult a healthcare professional. They may recommend a lipid profile and further evaluation.
2. Yellowish Deposits Around the Eyelids
Xanthelasma is a condition in which soft, yellowish patches develop around the eyelids, particularly near the inner corners of the eyes.
These patches contain lipid deposits and may occur in people with high cholesterol. However, they can also appear in people whose cholesterol levels are normal.
Xanthelasma is generally painless and may gradually become more noticeable over time.
What to do: Seek medical advice if you notice new yellowish patches around your eyelids. A cholesterol blood test can help determine whether abnormal lipid levels are present.
3. A Greyish-White Ring Around the Cornea
A greyish-white or bluish ring around the outer edge of the coloured part of the eye is called corneal arcus.
This ring forms when lipids accumulate around the cornea. It can be a normal age-related finding in older adults, but when it appears in a younger person, it may warrant an assessment for inherited high cholesterol.
The ring itself usually does not affect vision.
What to do: If you notice this change, especially at a younger age, consult an eye specialist or healthcare professional. They can assess whether cholesterol testing is appropriate.
4. Chest Pain During Physical Activity
High cholesterol does not directly cause noticeable symptoms in most people. However, over time, elevated LDL cholesterol can contribute to plaque buildup in the arteries supplying the heart.
When these arteries become narrowed, the heart muscle may receive insufficient oxygen during physical activity. This can cause angina, which may feel like pressure, tightness, heaviness, or discomfort in the chest.
Pain may also spread to the arms, shoulders, back, neck, or jaw.
Important: Chest pain is not a reliable early sign of high cholesterol; it can indicate an existing heart or blood vessel problem. Seek emergency medical care for new or severe chest pain, particularly when accompanied by shortness of breath, sweating, nausea, or faintness.
5. Pain or Cramping in the Legs While Walking
High cholesterol can contribute to peripheral artery disease (PAD), a condition in which narrowed arteries reduce blood flow to the legs.
A common symptom of PAD is intermittent claudication, which causes pain, aching, cramping, or tiredness in the calf, thigh, or buttock muscles while walking. The discomfort often improves after resting.
However, leg pain can have many other causes and does not automatically mean that cholesterol is high.
What to do: Consult a doctor if you repeatedly experience leg pain while walking, particularly if you have diabetes, smoke, or have other cardiovascular risk factors.
6. A Family History of High Cholesterol or Early Heart Disease
Family history is an important clue that you may be at increased risk of high cholesterol, even if you feel completely healthy.
Familial hypercholesterolaemia is an inherited condition that can cause very high LDL cholesterol from an early age. People with this condition may develop cholesterol deposits around their eyes or tendons and have an increased risk of premature heart disease.
If close relatives have high cholesterol or experienced a heart attack or stroke at a young age, you may benefit from earlier or more frequent cholesterol screening.
What to do: Tell your doctor about your family history and ask whether you should have a lipid profile or be evaluated for an inherited cholesterol disorder.
Can You Have High Cholesterol Without Any Symptoms?
Yes. Most people with high cholesterol do not experience any symptoms. You can have elevated LDL cholesterol even if you feel healthy, exercise regularly, and maintain a normal body weight.
This is why relying on physical symptoms alone is not a safe way to assess cholesterol levels. Skin and eye changes are uncommon and tend to occur in particular circumstances, while chest pain and leg pain may indicate complications rather than high cholesterol itself.
A blood test is the most reliable way to determine your cholesterol levels.
What Causes High Cholesterol?
Several factors can contribute to elevated cholesterol levels, including:
- Diet: Regularly eating foods high in saturated fat and trans fat can raise LDL cholesterol.
- Lack of physical activity: A sedentary lifestyle can negatively affect cholesterol levels and overall cardiovascular health.
- Excess body weight: Being overweight can contribute to an unhealthy lipid profile.
- Smoking: Smoking can lower HDL cholesterol and damage blood vessels.
- Genetics: Inherited conditions can cause high cholesterol even in otherwise healthy people.
- Age and medical conditions: Cholesterol levels can change with age, while conditions such as diabetes and hypothyroidism may affect lipid levels.
Understanding your individual risk factors can help your healthcare professional recommend suitable screening and prevention strategies.
How Do You Know If You Have High Cholesterol?
The most reliable way to identify high cholesterol is through a lipid profile blood test.
This test generally measures:
- Total cholesterol
- LDL cholesterol
- HDL cholesterol
- Triglycerides
Your doctor will interpret the results based on your age, medical history, family history, and overall cardiovascular risk. The appropriate cholesterol targets can vary between individuals, particularly for people with diabetes or existing heart disease.
Ask your healthcare professional how often you should be tested. People with known high cholesterol, diabetes, inherited cholesterol disorders, or a strong family history may need more frequent monitoring.
How Can You Lower High Cholesterol Naturally?
Healthy lifestyle changes can help improve cholesterol levels and reduce cardiovascular risk.
Eat a Heart-Healthy Diet
Include vegetables, fruits, whole grains, beans, lentils, nuts, and other fibre-rich foods in your daily meals. Choose healthier unsaturated fats, such as those found in nuts, seeds, and appropriate vegetable oils, instead of foods high in saturated or trans fats.
Exercise Regularly
Aim for regular physical activity suited to your health and fitness level. For many adults, around 150 minutes of moderate-intensity aerobic activity per week is a useful general target.
Maintain a Healthy Weight
If you are overweight, gradual and sustainable weight management may help improve your cholesterol and triglyceride levels.
Avoid Smoking
Quitting smoking supports healthier blood vessels and can improve your overall cardiovascular risk profile.
Follow Your Treatment Plan
Some people need cholesterol-lowering medicines, such as statins, alongside lifestyle changes. If your doctor prescribes medication, take it as directed and attend recommended follow-up appointments. Do not stop or replace prescribed treatment with supplements without medical advice.
Frequently Asked Questions (FAQs)
1. What are the first signs of high cholesterol?
High cholesterol usually has no early symptoms. Occasionally, very high cholesterol may be associated with yellowish fatty deposits on the skin or around the eyes, or a corneal ring. A blood test is necessary to confirm cholesterol levels.
2. Can high cholesterol cause headaches or dizziness?
High cholesterol itself does not usually cause headaches or dizziness. These symptoms can have many causes and should be assessed if they persist, recur, or occur with other concerning symptoms.
3. Can a blood test detect high cholesterol?
Yes. A lipid profile measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. Your doctor can interpret the results and advise whether lifestyle changes, medication, or further evaluation is needed.
4. How often should cholesterol levels be checked?
The frequency depends on your age, previous results, family history, and other risk factors. Ask your healthcare professional to recommend a suitable screening schedule.
5. Can high cholesterol be controlled without medication?
Some people can improve their cholesterol levels through dietary changes, regular exercise, weight management, and other lifestyle adjustments. Others need medication based on their LDL level and overall cardiovascular risk. Follow your doctor’s recommendations.
