Hypometabolic

Part of speech: adjective

Definitions

1. A physiological condition marked by a decrease in metabolic rate, often resulting in reduced energy consumption and activity levels
2. Characterized by a metabolic state significantly lower than normal, leading to decreased energy production and usage
3. Describing an organism or tissue with slowed biochemical activity and diminished metabolism

Etymology: "Hypometabolic" is a straightforward formation, built from the prefix "hypo-" and the adjective "metabolic." The prefix comes from Greek "hypo," meaning "under" or "below," and it signals a lower-than-usual level, as in "hypothermia" or "hypotension." The base, "metabolic," derives from the Greek "metabolē," meaning "change" or "transformation," which is also the source of "metabolism," the set of chemical processes by which living things convert food into energy and building materials. Put together, the two parts describe a body or organ operating beneath its normal rate of chemical activity. The term is most often used in medicine and physiology, for example to describe a brain region or a patient whose metabolism has slowed markedly, such as during deep sleep, hibernation, or certain disease states.
