High cholesterol usually causes no noticeable symptoms. You can have elevated LDL (“bad”) cholesterol for years and feel completely healthy. The most reliable way to find out whether your cholesterol is high is to have a blood test called a lipid panel.
This matters because cholesterol can gradually accumulate in artery walls, increasing the risk of heart disease and stroke without causing obvious warning signs.
What are the symptoms of high cholesterol?
For most people, there are no direct symptoms. However, a few physical signs can occasionally appear when cholesterol levels are extremely high, particularly in people with inherited cholesterol disorders.
1. Yellowish bumps on the skin
These fatty deposits, called xanthomas, can appear around the elbows, knees, hands, tendons, ankles or buttocks. They are not a typical sign of mildly elevated cholesterol and may indicate a serious underlying lipid disorder. Other conditions can also cause skin lumps, so a clinician should evaluate them.
2. A grayish-white ring around the cornea
This ring, called corneal arcus, forms around the outer edge of the colored part of the eye. In younger people, it can be a clue to unusually high cholesterol. In older adults, it commonly occurs with aging and does not automatically mean cholesterol is high.
These signs are uncommon and are not reliable screening methods. You should not wait for physical changes before checking your cholesterol.
Can high cholesterol cause headaches, dizziness or tiredness?
High cholesterol itself generally does not cause headaches, dizziness, fatigue, or a feeling of heaviness in the head.
These symptoms can have many different causes. They cannot reliably tell you whether your cholesterol is elevated.
The important distinction is that cholesterol can contribute to conditions that do cause symptoms. For example:
Chest discomfort during activity: May occur when narrowed heart arteries restrict blood flow.
Pain in the legs while walking: Can occur with peripheral artery disease, in which narrowed arteries reduce blood flow to the legs.
Sudden weakness, facial drooping or difficulty speaking: May indicate a stroke.
These are not routine symptoms of high cholesterol. They may signal cardiovascular complications and require appropriate medical assessment.
Seek emergency medical care for chest pressure or pain, especially with shortness of breath, sweating or nausea, or for sudden stroke symptoms. Do not wait for a cholesterol test.
How do you know if your cholesterol is high?
A lipid panel measures the main fats in your blood that help assess cardiovascular risk.
Test | What it tells you |
|---|---|
Total cholesterol | The overall amount of cholesterol measured in your blood |
LDL cholesterol | The cholesterol most associated with plaque buildup in arteries |
HDL cholesterol | The cholesterol involved in carrying cholesterol back toward the liver |
Triglycerides | Another type of blood fat that can contribute to cardiovascular risk when elevated |
For many adults, total cholesterol below 200 mg/dL, LDL below 100 mg/dL and triglycerides below 150 mg/dL are commonly used reference points. HDL of at least 40 mg/dL in men and 50 mg/dL in women is generally desirable. However, these are not universal treatment targets: your appropriate LDL goal depends on your overall cardiovascular risk and medical history.
A healthcare professional can help interpret your results. Some people need testing more often because of diabetes, existing heart disease, a family history of high cholesterol or other risk factors.
Ask the laboratory or clinician whether you need to fast before the test. Some lipid panels can be performed without fasting.
Who is more likely to have high cholesterol?
You may have a higher risk if you:
Have a parent, sibling or other close relative with high cholesterol, especially if they developed heart disease at a young age.
Have diabetes, kidney disease or certain other medical conditions.
Eat a diet high in saturated fats, such as fatty meats, butter and some high-fat dairy products.
Get little physical activity or smoke.
Have an inherited condition such as familial hypercholesterolemia, which can cause very high LDL cholesterol from an early age.
Being young, slim or physically active does not guarantee healthy cholesterol levels. Genetics and other health factors can influence your results even when you feel well.
What should you do if you suspect high cholesterol?
Rather than trying to identify symptoms, take these practical steps.
Arrange a lipid panel. This is the most direct way to determine your cholesterol levels.
Review your family history. Tell your healthcare professional if close relatives have very high cholesterol or experienced early heart disease.
Improve your eating pattern. Replace some foods high in saturated fat with options such as oats, beans, lentils, nuts, vegetables and unsaturated oils.
Stay physically active. Choose regular activity that suits your fitness level and medical circumstances.
Discuss treatment if your results are elevated. Lifestyle changes are important, but some people also need cholesterol-lowering medication. Do not start, stop or change medication without professional guidance.
The right treatment depends on your LDL level, overall cardiovascular risk and medical history.
Frequently asked questions
Can you have high cholesterol without knowing it?
Yes. Most people with high cholesterol feel normal. A blood test is needed to identify elevated levels.
What is the first warning sign of high cholesterol?
There is usually no first warning sign. A routine blood test may reveal the problem before any complications develop.
Can high cholesterol cause chest pain?
Not usually by itself. However, cholesterol-related plaque buildup can narrow the arteries supplying the heart and cause chest discomfort. Chest pain can also have other causes and should be assessed appropriately.
At what age should you check your cholesterol?
Cholesterol screening can begin in childhood. For most healthy adults, the CDC says testing every four to six years may be appropriate, but people with cardiovascular disease, diabetes, a strong family history or other risk factors may need more frequent testing. Ask your healthcare professional what schedule is suitable for you.
The Final Takeaway
High cholesterol is often a silent condition. Headaches, tiredness and dizziness are not dependable indicators, and the absence of symptoms does not mean your arteries are healthy.
A lipid panel, interpreted alongside your other cardiovascular risk factors, is the practical way to find out whether your cholesterol needs attention. Early detection gives you an opportunity to address the problem before serious complications occur.
