What is the Origin of Lost Productivity?

This term is derived from health economics, where the total burden of a disease is calculated by summing the direct medical costs and the indirect costs, with lost productivity being a major component of the latter. Its application in endocrinology highlights the tangible societal impact of conditions like hypothyroidism, hypogonadism, or severe menopausal symptoms on functional capacity.

What is the Mechanism of Lost Productivity?

Hormonal deficiencies or excesses directly impair physiological systems essential for optimal cognitive function and physical performance. For instance, low thyroid hormone or testosterone can induce profound chronic fatigue and "brain fog," resulting in presenteeism—working at a significantly reduced capacity. The underlying mechanism is the disruption of cellular energy metabolism and neuroendocrine signaling, which collectively diminishes the necessary motivation, focus, and physical endurance for productive output.

Lost Productivity

Meaning

Lost productivity is an economic and public health metric that quantifies the reduction in a person’s capacity to perform work, either in a paid employment setting (absenteeism or presenteeism) or in their daily non-work activities, directly attributable to a health condition. In the domain of hormonal health, this loss is often linked to debilitating symptoms arising from hormonal imbalances, such as chronic fatigue, significant cognitive impairment, or severe mood disturbances. It represents a substantial indirect cost of illness to the individual and society.
