High cholesterol almost never causes symptoms you can feel. Most people find out only through a blood test called a lipid panel, which is why routine screening matters so much. There are a few visible physical signs that can hint at elevated cholesterol, but the absence of those signs doesn’t mean your levels are normal.
Why High Cholesterol Has No Obvious Symptoms
Cholesterol builds up slowly inside artery walls over years or decades. Unlike high blood sugar or an infection, this process doesn’t trigger pain, fatigue, or any sensation you’d notice day to day. By the time cholesterol buildup causes problems you can feel, it has usually already progressed to significant artery narrowing or blockage. That’s why high cholesterol is often called a “silent” condition.
Physical Signs That Can Point to High Cholesterol
A small number of people develop visible clues, especially those with very high levels or a genetic form of the condition called familial hypercholesterolemia (FH). These signs aren’t common, but they’re worth knowing about.
Changes Around the Eyes
Yellowish, soft bumps on the skin above or around the eyes, particularly near the nose, are called xanthelasma. They’re painless deposits of cholesterol under the skin. Not everyone who has them has high cholesterol, but they’re a reason to get tested if you haven’t recently.
A bluish or whitish-gray ring near the outer edge of the cornea, the clear front surface of your eye, is another possible sign. This ring is common in older adults and often harmless, but in someone under 45 it can signal abnormally high cholesterol.
Bumps Near Joints or Tendons
People with familial hypercholesterolemia sometimes develop cholesterol deposits that show up as bumps or lumps around the knees, knuckles, or elbows. The Achilles tendon at the back of the ankle can also become swollen or painful from cholesterol buildup. These signs are uncommon in the general population, but a doctor spotting them during a physical exam would likely order blood work right away.
Signs That Cholesterol Has Already Caused Damage
When cholesterol narrows the arteries in your legs, a condition called peripheral artery disease, you may notice symptoms that seem unrelated to cholesterol at first. Cramping or aching in your calves, thighs, or hips during walking or climbing stairs, which goes away when you rest, is a classic sign. Other warning signals include coldness in one foot compared to the other, slow hair growth on the legs, sores on the feet or toes that heal poorly, and erectile dysfunction in men.
These aren’t signs of high cholesterol itself. They’re signs that high cholesterol has already done real damage to your blood vessels. If you’re experiencing any of them, a lipid panel is only one part of the workup you’d need.
The Only Reliable Way to Know: A Blood Test
A lipid panel measures several types of cholesterol and fat in your blood. Here’s what healthy numbers look like for adults age 20 and older:
- Total cholesterol: below 200 mg/dL
- LDL (“bad”) cholesterol: below 100 mg/dL
- HDL (“good”) cholesterol: 60 mg/dL or higher is ideal; below 40 mg/dL for men or below 50 mg/dL for women is considered low
For children and teens age 19 and under, the targets are tighter: total cholesterol below 170 mg/dL and LDL below 110 mg/dL. In familial hypercholesterolemia, LDL levels often exceed 190 mg/dL in adults and 160 mg/dL in children.
Your cholesterol numbers alone don’t tell the full story. Doctors also factor in your age, blood pressure, whether you smoke, and whether you have diabetes to estimate your overall risk of a heart attack or stroke over the next ten years. Two people with the same LDL number can have very different risk levels depending on these other factors.
Do You Need to Fast Before the Test?
Traditionally, doctors asked you to fast for 9 to 12 hours before a lipid panel. That guidance has shifted. Medical societies in the U.S., Europe, Canada, and several other countries now endorse nonfasting lipid panels for most people. Eating before the test raises triglycerides by about 26 mg/dL on average and shifts LDL and total cholesterol by only about 8 mg/dL in either direction. Those differences are too small to change clinical decisions in most cases.
Your doctor may still request a fasting test if your triglycerides come back very high on an initial nonfasting draw, since fasting gives a more precise triglyceride reading at extreme levels. But for a routine screening, you can generally get your blood drawn at any time of day without worrying about what you ate.
How Often to Get Tested
The CDC recommends that children have their cholesterol checked at least once between ages 9 and 11, and again between ages 17 and 21. After that, most healthy adults should be tested every four to six years. If you have heart disease, diabetes, or a family history of high cholesterol, you’ll need testing more frequently, and your doctor will set that schedule based on your specific situation.
Home Cholesterol Test Kits
Over-the-counter cholesterol kits use a finger prick to measure your levels at home. Some are reasonably accurate, but results vary by brand and depend heavily on following the instructions correctly. Most home kits measure only total cholesterol. Some also measure HDL and triglycerides, then calculate LDL using a formula. None give you the complete clinical picture a lab-drawn panel provides, and they can’t assess your overall cardiovascular risk the way a doctor’s visit can.
A home test can be a useful starting point if you haven’t been screened in years and want a quick read on where you stand. But if the result comes back high, or if you have risk factors like a family history of heart disease, follow up with a full lab panel.
Who Should Get Tested Sooner Rather Than Later
Certain factors make high cholesterol more likely, even in people who feel perfectly healthy. If any of these apply to you, it’s worth getting a lipid panel soon rather than waiting for your next routine physical:
- Family history: a parent or sibling diagnosed with high cholesterol or early heart disease (before age 55 in men, 65 in women)
- Obesity or a diet high in saturated fat
- Diabetes or prediabetes
- Smoking
- Physical inactivity
- Age over 40 without a recent test
High cholesterol is one of the most manageable risk factors for heart disease, but only if you know about it. Since your body won’t send you a clear warning, the blood test is the warning system.
