What health risks are associated with high cholesterol levels?

High cholesterol levels are primarily associated with an increased risk of heart disease and stroke. Cholesterol is a waxy substance found in the blood that is essential for various bodily functions, but when levels are too high, particularly low-density lipoprotein (LDL) cholesterol, it can lead to the buildup of plaque in the arteries. This buildup narrows the arteries and can lead to atherosclerosis, which significantly raises the likelihood of cardiovascular events such as heart attacks and strokes.

Understanding this mechanism highlights the importance of maintaining healthy cholesterol levels through diet, exercise, and, when necessary, medications. Monitoring cholesterol levels is crucial for identifying individuals at risk for cardiovascular diseases, allowing for early intervention and management to mitigate these health risks.
