High cholesterol, also known as hypercholesterolemia, means having too much of a fatty substance called cholesterol in the blood. Over time, this can raise the risk of severe health complications such as heart attacks and strokes.
Cholesterol build-up can block arteries, impeding proper blood flow and significantly increasing the danger of cardiovascular disease. In the UK, cardiovascular disease causes approximately a quarter of all deaths. The most concerning issue is that high cholesterol typically has no symptoms, meaning countless cases go undetected until a medical emergency or a routine GP blood test.
The NHS confirms this silent nature: "High cholesterol does not usually cause symptoms. You can only find out if you have it from a blood test."
Warning Signs in the Legs
Despite this, certain warning signs could prove lifesaving if identified early. One such indicator is peripheral arterial disease (PAD), a widespread condition where fatty deposits in the arteries block blood supply to leg muscles. The NHS states this "restricts" circulation to these muscles.
PAD doesn't always produce noticeable symptoms, but it can trigger warning signs in the legs, as reported by Surrey Live. The NHS has outlined indicators including hair loss and foot ulcers. "The symptoms of PAD often develop slowly, over time," the health body advises. "If your symptoms develop quickly, or get suddenly worse, it could be a sign of a serious problem requiring immediate treatment."
Recognising the Symptoms
An aching pain while walking is the most frequently reported symptom. This discomfort "usually" subsides after a few minutes' rest, says the NHS. The pain can range from mild to severe and typically eases after giving your legs a short rest. "Both legs are often affected at the same time, although the pain may be worse in one leg."
Further symptoms of PAD can include shiny skin and erectile dysfunction. Having PAD also significantly increases the risk of coronary heart disease, the leading cause of death among cardiovascular diseases in the UK.
Next Steps
If you're worried you may have PAD, or are concerned about your cholesterol levels, consult your doctor. To lower cholesterol, the NHS recommends eating less fatty food, quitting smoking, cutting down on alcohol, and getting more exercise.
