Overview

• UKHSA warns many people are completely unaware of elevated cholesterol, with reports estimating roughly 40% of UK adults are affected.
• High cholesterol can lead to arterial blockages that raise the risk of heart attacks and strokes.
• The only definitive check is a blood test, with higher risk among people over 40, those who are overweight, or with a family history of heart disease.
• The British Heart Foundation says familial hypercholesterolaemia can show visible signs such as tendon xanthomata, xanthelasma around the eyes, and a corneal arcus.
• Peripheral artery disease in the legs and feet—signaled by pain, ulcers, color changes, hair loss, numbness, or slow-healing sores—may point to cholesterol problems, while NHS advice focuses on reducing saturated fat, exercising, quitting smoking, moderating alcohol, and using medicines when risk remains high.
