The article from Iltalehti highlights the often unnoticed yet critical warning signs associated with high cholesterol, commonly known as a 'silent killer' due to its lack of overt symptoms. Elevated cholesterol is a significant risk factor for cardiovascular diseases, including heart attacks and strokes, which makes it vital for individuals to be aware of the symptoms that might indicate their cholesterol levels are dangerously high.

Three visible symptoms are detailed in the article, with a particular emphasis on the genetic condition known as familial hypercholesterolemia—where high cholesterol is inherited. One key indicator that may be visible on an individual's body is the presence of xanthomas, which are fat deposits that can form in tendons, including on the Achilles tendon. These deposits can occur without skin discoloration, making them difficult to detect without proper screening.

The implication of recognizing these symptoms cannot be overstated, as they may serve as a critical warning for individuals, especially young people, who are at risk due to hereditary conditions affecting cholesterol metabolism. Awareness and steps toward managing cholesterol levels can significantly contribute to reducing the risk of serious health issues like heart disease and stroke, emphasizing the importance of proactive medical care and lifestyle adjustments.
