What is the Origin of Physiological Change?

The term is derived from 'physiology,' the scientific study of the normal function in living systems, and 'change,' referring to a transition from one state to another. It is a broad, foundational concept in all biological and medical sciences. In a clinical setting, it is used to describe the objective, measurable effects—both desirable and undesirable—of a health protocol on the body's internal workings.

What is the Mechanism of Physiological Change?

Physiological change is mechanistically driven by alterations in gene expression, protein activity, and cellular communication, often initiated by hormonal signals binding to their specific receptors. For example, a change in thyroid hormone levels triggers a cascade that alters the metabolic rate of nearly every cell in the body. The mechanism involves complex, interconnected feedback loops, where a change in one system inevitably propagates effects throughout the entire organism.

Physiological Change

Meaning

Any detectable alteration in the normal functioning of a living organism or its constituent systems, ranging from molecular and cellular levels to whole-body responses. In the context of hormonal health, this term refers to the measurable shifts in endocrine function, metabolic markers, and organ system performance resulting from aging, disease, or therapeutic intervention. Monitoring these changes is the fundamental basis for clinical assessment, protocol adjustment, and evaluating the efficacy of any treatment.
