Slow-growing, brittle toenails may be an early warning sign of dangerously high cholesterol levels, according to health experts. The symptom is linked to peripheral arterial disease (PAD), a condition where fatty deposits restrict blood flow to the legs.
High cholesterol, known as a 'silent killer', often shows no symptoms until a heart attack or stroke occurs. However, PAD can cause noticeable changes in the feet, including hair loss and non-healing ulcers, alongside brittle toenails.
The NHS warns that PAD symptoms may develop slowly, but a sudden worsening requires urgent medical attention. A common sign is a painful ache in the legs during walking, which eases with rest. Both legs are typically affected, though one may be more painful.
PAD increases the risk of coronary heart disease, the leading cause of death in the UK. To lower cholesterol, the NHS recommends a healthy diet, regular exercise, and medication if necessary. Anyone concerned about their cholesterol should consult their GP.
