The correct answer is: Excessive, above, over

The prefix "Hyper-" in medical terminology signifies an excessive level, an above-average condition, or something that is over normal limits. It is commonly used to describe various medical conditions. For example, in "hypertension," it refers to high blood pressure, indicating that the blood pressure readings are above the normal range. This prefix helps to convey the severity or degree of a condition, such as hyperglycemia, which indicates an excess of glucose in the blood. Using "Hyper-" effectively communicates the concept of elevated levels, which is essential for accurate medical understanding and diagnosis.
