What does hyperlipidemia indicate?

Hyperlipidemia refers to elevated levels of lipids in the blood, which primarily include cholesterol and triglycerides. When a person is diagnosed with hyperlipidemia, it typically means that their cholesterol levels are higher than what is considered healthy. High cholesterol levels can increase the risk of cardiovascular diseases, including heart attacks and strokes, making it an important condition to monitor and manage through lifestyle changes or medication if necessary.

In contrast, low cholesterol levels would indicate hypolipidemia, and normal cholesterol levels would not qualify as hyperlipidemia. Unstable blood sugar levels concern a different metabolic disorder, primarily associated with diabetes and not directly related to lipid levels in the blood. Hence, the definition of hyperlipidemia points directly to high cholesterol levels, affirming that the selected answer is accurate.
