Functional Insufficiency

Meaning

Functional Insufficiency is a precise clinical term in endocrinology and physiology denoting the inadequate performance of an organ or system to maintain the body’s normal homeostatic state, even if the organ itself is not structurally destroyed. In the hormonal health context, it describes a state where an endocrine gland produces hormones at a sub-optimal level that is insufficient to meet the individual’s metabolic or physiological demands, leading to symptomatic decline. This condition may not meet the criteria for overt organ failure but still significantly impacts quality of life.
