What health risk is associated with excessive cholesterol in the body?

The association between excessive cholesterol in the body and health risks such as stroke and heart attack is well established. Cholesterol is a type of fat found in the blood, and while it is essential for various bodily functions, an excess can lead to the formation of plaque in the arteries. This plaque buildup narrows the arteries, a condition known as atherosclerosis, which can impede blood flow. If a blood clot forms in a narrowed artery, it can block blood flow to the heart or brain, resulting in a heart attack or stroke, respectively.

Managing cholesterol levels is critical for cardiovascular health, and individuals are often advised to maintain healthy levels through diet, exercise, and, if necessary, medication. Concerns about cholesterol are particularly significant for individuals with other risk factors for heart disease, such as high blood pressure or diabetes, further emphasizing the need for awareness and management.

By contrast, the other options do not accurately reflect the specific and serious health risks tied directly to high cholesterol levels in the body. Reduced metabolic rate and weight gain are not directly caused by cholesterol excess, and better nutrient absorption is typically not a consequence of high cholesterol. Therefore, recognizing the direct link between excessive cholesterol and life-threatening conditions like stroke and heart attack is crucial in understanding
