High cholesterol itself produces no symptoms in the vast majority of people. The CDC states it plainly: “High cholesterol has no symptoms, so many people don’t know that their cholesterol is too high.” Nearly 25 million adults in the United States have total cholesterol above 240 mg/dL, and most of them feel perfectly fine. That said, when cholesterol levels stay elevated long enough, the damage it causes can produce visible and physical warning signs. Here are five of them.
1. Yellow Deposits on the Skin or Tendons
When cholesterol and other fats accumulate in large amounts, they can form visible deposits called xanthomas. These show up in two main ways. Eruptive xanthomas appear as crops of small yellow bumps, roughly 2 to 5 millimeters across, often ringed in red. They tend to cluster on the buttocks, shoulders, and other outer surfaces of the body, and can sometimes appear inside the mouth.
Tendon xanthomas are different. They’re slow-growing nodules that attach to tendons, most commonly the Achilles tendon at the back of the ankle or the tendons over the knuckles. They feel smooth and firm when pressed and can be moved slightly under the skin. Tendon xanthomas are particularly associated with familial hypercholesterolemia, a genetic condition that drives cholesterol levels extremely high from a young age. People who inherit the condition from both parents can develop these deposits in childhood.
2. Yellow Patches Around the Eyes
Yellowish, slightly raised patches on or near the eyelids are one of the most recognizable cholesterol-related skin changes. They tend to appear on the inner corners of the upper or lower eyelids and are soft, flat, and painless. You might notice them while looking in the mirror before anything else feels wrong.
Here’s the nuance: a 2024 study in the journal Ophthalmology compared people with these eyelid deposits to people without them and found that their cholesterol numbers were statistically similar. Rates of cardiovascular disease were also comparable between the two groups. So while these patches can signal a lipid problem, they don’t always mean your cholesterol is dangerously high. If you spot them, it’s worth getting a blood test to find out where you actually stand.
3. A Gray or White Ring Around the Eye
A hazy arc or full ring around the colored part of your eye (the iris) is caused by fatty deposits building up at the edge of the cornea. In people over 50 or 60, this is considered a normal part of aging and doesn’t necessarily reflect high cholesterol. The significance changes dramatically with age.
If you’re under 40 and notice this ring, or if it appears in only one eye, it raises suspicion for an underlying lipid disorder. In younger people, the ring can be one of the earliest visible clues of familial hypercholesterolemia. It’s painless and doesn’t affect vision, so it’s easy to overlook unless someone, often an eye doctor, points it out during an exam.
4. Leg Pain or Cramping When Walking
Over years, cholesterol-laden plaque can narrow the arteries that supply blood to your legs. This is peripheral artery disease (PAD), and its classic symptom is pain, aching, or cramping in the legs during physical activity that goes away with rest. The discomfort can hit anywhere from the calf to the thigh, hip, or buttock, depending on where the blockage is.
What makes PAD tricky is that up to 4 in 10 people with the condition have no leg pain at all. Instead, they might notice subtler changes: hair loss on the legs, skin that becomes smooth and shiny, feet that feel cool to the touch, slow-healing sores on the legs or feet, or cold and numb toes. These physical signs reflect reduced blood flow and are worth taking seriously even if there’s no pain involved.
5. Chest Pain or Pressure
When cholesterol plaque builds up inside the coronary arteries (the ones feeding the heart), it can restrict blood flow enough to cause chest pain known as angina. This typically feels like pressure, squeezing, tightness, or heaviness behind the breastbone. The sensation usually builds over a few minutes rather than hitting all at once, and it can radiate to the shoulders, arms, neck, back, or jaw.
Stable angina is triggered by physical activity or stress and eases with rest. Other forms can strike during sleep or while sitting still. Any of these patterns reflect significant artery narrowing that has likely been developing for years. By the time chest pain appears, cholesterol has already done substantial damage to the artery walls.
Why These Signs Appear Late
Every sign on this list represents cholesterol damage that has been accumulating over a long period. High cholesterol doesn’t hurt, doesn’t cause fatigue, and doesn’t make you feel sick. The deposits, blockages, and pain develop only after cholesterol has had years or decades to build up in tissues and artery walls. That’s why roughly 86 million U.S. adults have total cholesterol above 200 mg/dL, yet most have no idea.
The only reliable way to detect high cholesterol before it causes damage is a blood test. Healthy adults should have their cholesterol checked every 4 to 6 years, and adolescents should get their first screening between ages 17 and 21. For adults, the healthy targets are total cholesterol below 200 mg/dL, LDL (the “bad” cholesterol) below 100 mg/dL, and HDL (the “good” cholesterol) at 60 mg/dL or above. Men with HDL below 40 and women with HDL below 50 are considered low.
If you’re searching for visible signs of high cholesterol, the honest answer is that waiting for symptoms is not a safe strategy. The signs described above are real, but they represent late-stage consequences. A simple blood draw every few years catches the problem long before any of them appear.
