High cholesterol signs that appear on your skin before a heat test

High cholesterol is a widespread health concern that impacts millions globally, including in the UK. In its early stages, it usually has no obvious symptoms, making it a silent risk factor for heart disease and stroke. However, in some cases, excess cholesterol can manifest through visible signs on the skin. These include yellowish patches around the eyes (xanthelasma), fatty deposits called xanthomas, or other subtle changes. Such symptoms often indicate significantly elevated cholesterol levels or genetic conditions like familial hypercholesterolaemia. Recognising these early warning signs and seeking medical advice is crucial for timely diagnosis, effective management, and reducing long-term cardiovascular risksCholesterol is a fatty substance essential for various bodily functions, but when its levels become too high, it can lead to plaque buildup in the arteries. In some cases, excess cholesterol deposits can accumulate in the skin and tendons, leading to noticeable changes. These skin symptoms are often associated with lipid metabolism disorders and, in rare cases, signal more severe conditions such as familial hypercholesterolaemia.According to research published in the British Journal of Dermatology and data from the NHS, high cholesterol can lead to several skin-related symptoms. These may include yellowish deposits, nodules, or changes around the eyes and tendons. Although these signs do not appear in every person with high cholesterol, their presence can serve as an important clinical clue.1. Xanthelasma (Yellow patches around the eyes)Xanthelasma are soft, yellowish plaques that usually develop on or around the eyelids. They are composed of cholesterol deposits and are often seen in people with high LDL (bad) cholesterol levels. While usually harmless, xanthelasma can indicate an increased risk of cardiovascular disease.2. Xanthomas (Cholesterol deposits in the skin)Xanthomas are fatty deposits that appear as yellowish or reddish nodules under the skin. They can vary in size and location, commonly forming on:Elbows and knees (tuberous xanthomas)Tendons such as the Achilles or fingers (tendinous xanthomas)Buttocks and thighs (eruptive xanthomas)These often occur in patients with very high cholesterol or triglyceride levels.3. Arcus senilis (Grey or white ring around the cornea)Although not strictly on the skin, this sign is worth noting. Arcus senilis is a grey or white ring around the edge of the cornea, caused by lipid deposits. While common in older adults, its presence in younger individuals may suggest abnormal cholesterol levels.4. Skin tags and other changesIn some cases, clusters of skin tags, particularly on the eyelids or neck, may be linked to metabolic disorders, including high cholesterol. Other changes include thickened or slightly raised patches on the skin.Skin signs related to high cholesterol are usually caused by:While xanthelasma and xanthomas themselves are usually painless and benign, they often indicate a higher risk of heart disease or other lipid disorders. According to the National Institute for Health and Care Excellence (NICE), people with these signs should undergo a full lipid profile test to determine cholesterol levels and cardiovascular risk.If you notice any of the following, seek medical advice promptly:Disclaimer: This article is for informational purposes only and should not replace professional medical advice.
