High cholesterol, often referred to as the “silent killer,” can display subtle signs on the face despite typically being asymptomatic. This condition arises from an excess of cholesterol in the bloodstream, a vital substance that can become hazardous in excessive amounts.
The accumulation of excess cholesterol in the arteries can lead to their narrowing and hardening, impeding blood flow and elevating the risk of heart attacks and strokes. Surprisingly, around 40% of Britons may have high cholesterol unknowingly until diagnosed through blood tests or related health issues.
According to the British Heart Foundation (BHF), high cholesterol typically manifests without symptoms but can result in severe consequences like heart attacks and strokes if left untreated. Detecting cholesterol levels early is crucial, as it often remains undetected until complications arise.
In some cases, specific symptoms, particularly when linked to familial hypercholesterolaemia, can manifest on the face. These include benign yellow growths near the eyelids close to the nose, known as xanthelasmas. These growths are caused by cholesterol deposits under the skin, as explained by the Cleveland Clinic.
Xanthelasmas are observed in about half of individuals with elevated cholesterol levels, although they could also indicate other conditions. Additionally, a grey or white arc around the iris, termed arcus senilis, may be visible in the eye, indicating potential high cholesterol levels.
While arcus senilis does not impact vision or require treatment, consulting a doctor upon noticing this sign is advised. To manage or prevent high cholesterol, the NHS recommends seeking medical advice if concerned about cholesterol levels.
