What does the prefix 'hypo-' commonly suggest about a condition or measurement?

The prefix 'hypo-' is derived from Greek, meaning "under" or "below." In medical terminology, it signifies a condition or measurement that is less than normal or below the usual level. For example, hypoglycemia refers to abnormally low levels of glucose in the blood. This understanding highlights that 'hypo-' indicates a deficiency or lower presence of a certain component or condition within the body. Hence, the choice indicating that the prefix suggests "less than normal" accurately captures this meaning.
