You searched "high cholesterol symptoms" because you want to know what to watch for, maybe a warning sign your body might be sending. Here's the honest answer that surprises most people: high cholesterol usually has no symptoms at all.
That's exactly why it matters. You can't feel it, and you often can't see it, until it has already done damage. But there are a few rare clues that can show up on your skin and eyes, and knowing them is worth a minute of your time.
What are the symptoms of high cholesterol?
For most people, high cholesterol produces no signs or symptoms whatsoever. According to the CDC, many people don't know their cholesterol is too high until they have a heart attack or stroke. There's no ache, no fatigue, no visible change in everyday cases.
Because cholesterol is silent, a blood test called a lipid panel is the only reliable way to detect it. High total cholesterol is defined as 240 mg/dL or more. Between 2017 and 2020, the CDC found that 10% of US adults age 20 and older had total cholesterol above that threshold, and a large share had no idea.
When physical signs do appear, they show up as cholesterol deposits in the skin and eyes rather than as a feeling. These are the visible clues worth recognizing.
Can high cholesterol show up on your skin and eyes?
Yes, occasionally. When cholesterol is very high, it can deposit in tissue and become visible. There are three main signs to know:
- Xanthelasma: soft, yellowish, waxy plaques on or around the eyelids, usually near the inner corner.
- Xanthomas: firmer yellowish nodules of cholesterol that can form on the hands, elbows, knees, and tendons such as the Achilles.
- Corneal arcus: a white or gray ring around the colored part of the eye (the iris).
Do these skin signs always mean my cholesterol is high?
Not always, and this is an important nuance. The American Academy of Dermatology notes that in about half of people with xanthelasma, cholesterol levels are actually normal. So the growths are not proof of a problem, but they are a clear reason to get your cholesterol checked.
Even so, these markers are worth taking seriously. A large general-population study, the Copenhagen City Heart Study published in the BMJ in 2011, found that xanthelasmata independently predicted heart attack, ischaemic heart disease, severe atherosclerosis, and death, even after accounting for measured cholesterol and triglyceride levels. In that same study, corneal arcus was not an independent predictor. In other words, if you notice yellowish plaques around your eyes, mention them to a doctor.
What about inherited high cholesterol?
Some people carry a genetic condition called familial hypercholesterolemia (FH), where cholesterol runs very high from a young age. The heterozygous form has an estimated prevalence of roughly 1 in 250 to 500 people.
In FH, the skin and eye signs are more common and can appear earlier in life. Tendon xanthomas, often on the Achilles tendon, elbows, and hands, eventually appear in about 75% of affected heterozygotes, and their incidence rises with age. In the rarer, more severe homozygous form, corneal arcus can appear before age 10. If high cholesterol or early heart disease runs in your family, that history matters more than any single skin sign.
Why does high cholesterol matter if I feel fine?
Because the real damage happens quietly inside your arteries. Excess cholesterol contributes to plaque that narrows and clogs arteries, a process called atherosclerosis. A piece of plaque can break loose and form a clot, which is what causes many heart attacks and strokes.
This is why screening matters even when you feel perfectly healthy. Most healthy adults should have their cholesterol checked every 4 to 6 years, according to the CDC and Mayo Clinic. People with heart disease, diabetes, or a family history of high cholesterol need it checked more often.
When should you see a doctor?
Get medical care promptly if you notice new yellowish deposits around your eyelids, firm nodules on your tendons or joints, or a ring around your iris, especially if you are younger or have a family history of heart disease or high cholesterol. These are reasons to get a lipid panel, not reasons to panic.
Treat sudden chest pain, shortness of breath, weakness on one side of the body, slurred speech, or facial drooping as an emergency and call your local emergency number right away, because these can signal a heart attack or stroke. For routine concerns, a clinician can order a simple blood test and, if needed, build a personalized plan. Tools like Nolla can make that first step easier, but the core action is the same: get your numbers checked.
