A seemingly harmless change in your toenails could be an early warning sign of a serious health issue. Experts from the NHS now point out that a subtle nail symptom may indicate dangerously high cholesterol levels — a condition that significantly increases the risk of heart attacks and strokes.
The silent threat

High cholesterol is often called a “silent killer” because it rarely causes noticeable symptoms until serious damage has occurred.
When fat builds up

The condition develops when excess cholesterol accumulates in the bloodstream, sticking to artery walls and narrowing them over time.
Heart under pressure

This buildup restricts blood flow and greatly raises the risk of cardiovascular disease — one of the leading causes of death worldwide.

Toenails as warning signs

One unexpected clue may appear on your feet: brittle, slow-growing toenails can be an early indicator of poor circulation.
Blood flow interruption

Reduced circulation is often linked to peripheral arterial disease (PAD), where fatty deposits clog the arteries in the legs.
More foot symptoms to watch

Other possible warning signs include hair loss on the legs and ulcers or sores that take a long time to heal.
Pain while walking

A common symptom of PAD is aching or cramping in the legs during walking that eases after a short rest.

Skin changes

Pale, bluish, or shiny skin can suggest reduced blood flow — especially noticeable in colder conditions.
Higher heart disease risk

People with PAD face a much greater chance of developing coronary heart disease and related complications.
Lower your cholesterol

The NHS advises cutting down on fatty foods, staying active, quitting smoking, and limiting alcohol to reduce cholesterol levels.
Talk to your doctor

A simple blood test can detect high cholesterol early, allowing treatment before it leads to serious illness.
