What is the meaning of the prefix "hyper" in medical terms?

The prefix "hyper" in medical terminology is derived from the Greek word meaning "over" or "excess." It is commonly used to describe conditions characterized by an abnormal increase or excess in a particular function, substance, or condition within the body. For instance, terms like "hypertension" refer to high blood pressure, and "hyperglycemia" refers to elevated blood sugar levels.

The other options do not align with the definition of "hyper." "Low" suggests a decrease, which is the opposite of what "hyper" denotes. "Normal" indicates a standard or average condition, while "laboratory" pertains to a setting for medical tests and procedures rather than a prefix that indicates a specific condition. Understanding this prefix is essential for medical interpreters, as it clarifies communication about various health conditions and abnormalities.
