The NHS is urging people to check their hands and feet for warning signs of high cholesterol, a condition often called a 'silent killer' because it typically shows no symptoms until serious damage has occurred.
One early indicator can be changes in your nails. Healthy nails are smooth, pink, and free of ridges or dents. A shift to pale white, yellow, or blue may suggest reduced circulation due to cholesterol blockages. Slower nail growth, unusually thick or brittle nails, and dark lines under the nails (splinter haemorrhages) can also be red flags.
High cholesterol is usually detected only through a blood test. The NHS notes that it 'does not usually cause symptoms' but can increase the risk of heart attacks and strokes. Risk factors include unhealthy diet, smoking, excess weight, age, and family history.
If diagnosed, lifestyle changes are recommended: reduce saturated fat intake, eat unsaturated fats, and exercise for at least 150 minutes per week. Doctors may also prescribe statins. Anyone concerned should consult their GP for testing and treatment.
