Health experts have highlighted two subtle yet significant facial indicators that may point to a potentially deadly condition: high cholesterol. Often referred to as a “silent killer,” high cholesterol usually shows no outward symptoms, making it difficult to detect without medical tests.
Cholesterol is a fatty substance in the blood that, while essential in small amounts, can pose serious risks when levels become too high. Excess cholesterol can accumulate in blood vessels, narrowing and hardening them. This can impede blood flow and significantly increase the risk of heart attacks and strokes.
In the UK, an estimated two in five people live with high cholesterol, but many remain unaware of their condition until a related health issue arises or they undergo testing. The British Heart Foundation (BHF) warns:
“There are usually no symptoms of high cholesterol. But if left untreated, it can lead to heart attack and stroke. It’s often a hidden risk factor which means it can happen without us knowing until it’s too late. That is why it’s so important to get your cholesterol level checked.”
However, in rare cases, people with familial hypercholesterolaemia—a genetic form of high cholesterol—may exhibit noticeable facial signs. The BHF identifies two such warning signs:
- Xanthelasmas: These are small, yellow cholesterol deposits that form near the inner corner of the eye, often appearing as harmless lumps on or by the eyelids. According to the Cleveland Clinic, “Cholesterol deposits build up under your skin to form a xanthelasma.” Approximately half of individuals with xanthelasmas have high cholesterol levels. These deposits may also indicate other conditions such as diabetes or thyroid issues.
- Corneal Arcus: This condition presents as a pale white or grey arc around the iris, the colored part of the eye. Cardiologist Francisco Lopez-Jimenez from the Mayo Clinic explains:
“Eventually, the arc may become a complete ring around the iris. The iris is the coloured portion of the eye.”
Although this doesn’t affect vision or require treatment, it’s important to consult a GP if this sign is noticed.
To prevent or manage high cholesterol, the NHS recommends lifestyle changes such as reducing saturated fat intake, eating a balanced diet, exercising regularly, avoiding smoking, and limiting alcohol consumption. Early detection and proactive measures can help reduce the risks associated with this silent condition.
