Rare warning sign in your eye could be a symptom of high cholesterol

High cholesterol is a concern for many, as it can result in blocked blood vessels and heighten the risk of strokes or heart issues. It's often caused by consuming fatty foods and lack of exercise, but lifestyle changes can help lower cholesterol levels.

But how can you tell if your cholesterol is high? High cholesterol typically doesn't present any symptoms, but familial hypercholesterolaemia may exhibit visible signs. One such sign is corneal arcus - a pale white ring around the iris of your eye.

Another physical symptom is xanthelasmas, small yellow cholesterol deposits near the inner corner of your eye. Swellings on the knuckles of your hands, knees, or Achilles tendon, known as tendon xanthomata, may also occur.

Familial hypercholesterolaemia is a genetic condition, meaning it's present from birth, reports Surrey Live. Despite potentially having no other risk factors, this condition can lead to very high cholesterol levels due to faulty genes passed down through families, as explained by the British Heart Foundation.

While high cholesterol can be hereditary, other groups at higher risk include those over 50, men, post-menopausal women, and individuals of South Asian or sub-Saharan African descent.

Cholesterol levels are typically determined through a blood test, with results usually available within a few days. The NHS also notes that individuals over 40 may have their cholesterol checked during an NHS Health Check, which involves a quick finger prick test with results returned in minutes.

One way to lower cholesterol is by reducing the intake of fatty foods. This includes cutting back on items such as meat pies, sausages, butter, cream, hard cheese, cakes, biscuits, and products containing coconut or palm oil.

Physical activity can also contribute to lowering cholesterol, with a recommended minimum of 150 minutes of exercise per week. Quitting smoking is advised as it can increase cholesterol levels, and alcohol consumption should be limited to no more than 14 units per week, as per NHS guidelines.

If cholesterol levels remain high despite dietary and lifestyle changes, doctors may prescribe medication in the form of pills or injections.
