Two warning signs of a "silent killer" condition could appear on the face. High cholesterol earns its nickname the "silent killer" due to generally being symptomless, however, there are some lesser-known signs.

The condition develops when excessive levels of a fatty substance known as cholesterol build up in the blood. While the body needs some cholesterol to function correctly, too much can be dangerous.

Excess cholesterol can accumulate in the arteries, causing them to narrow and harden, which restricts blood flow and increases the risk of heart attacks and strokes. Approximately two in five Brits are believed to have high cholesterol, with many remaining unaware until they have blood tests or experience associated health problems.

• Dog owners told 'do one thing' after every walk this winter

The British Heart Foundation (BHF) says: "There are usually no symptoms of high cholesterol. But if left untreated, it can lead to heart attack and stroke."

It also warns that: "It's often a hidden risk factor, which means it can happen without us knowing until it's too late. That is why it's so important to get your cholesterol level checked."

However, particular symptoms can occasionally emerge, especially when high cholesterol results from familial hypercholesterolaemia - an inherited condition. In these instances, distinctive signs may appear on the face, which the BHF highlights to increase awareness:

• Xanthelasmas - small, yellow lumps of cholesterol near the inner corner of your eye


• Corneal arcus - this is a pale white ring around the coloured part of your eye, your iris

These are "harmless" yellow growths that appear on or by the corners of your eyelids next to your nose. The Cleveland Clinic says: "Cholesterol deposits build up under your skin to form a xanthelasma."

Approximately half of those who develop xanthelasmas have elevated cholesterol levels. However, xanthelasmas could indicate another condition, such as:

• Diabetes


• Thyroid problems

This presents as a grey or white arc visible in the eye above and below the outer cornea. Cardiologist Francisco Lopez-Jimenez, writing for the Mayo Clinic, said: "Eventually, the arc may become a complete ring around the iris. The iris is the coloured portion of the eye."

He added that it doesn't affect your vision or need treatment. But if you notice this sign, you should consult your GP. To prevent high cholesterol or to reduce your levels the NHS recommends:

• Eating less saturated fat


• Eating a healthy, balanced diet


• Exercising regularly


• Stopping smoking


• Reducing your alcohol intake

If you are concerned about your cholesterol you should speak to a doctor.
