What is the Origin of Physiologic Setpoint Adjustment?

This concept is a fundamental principle of cybernetics and control theory applied to human physiology, particularly endocrinology. A setpoint is the ideal or optimal value maintained by a negative feedback loop. Adjustment denotes the active, clinical recalibration of this value for improved health outcomes.

What is the Mechanism of Physiologic Setpoint Adjustment?

The hypothalamus and pituitary gland often function as the central controllers for many hormonal setpoints, such as the thyroid-stimulating hormone (TSH) level that governs thyroid hormone output. Through targeted intervention, such as optimizing thyroid hormone replacement, the feedback loop is influenced to accept a TSH value that results in free thyroid hormone concentrations at the high-normal range. This adjustment supports robust cellular metabolism and energy production.

Physiologic Setpoint Adjustment

Meaning

Physiologic Setpoint Adjustment is the therapeutic goal of intentionally modifying the regulated, homeostatic target value for a specific physiological parameter, such as core body temperature, blood glucose, or circulating hormone concentration. The body’s setpoints often drift sub-optimally with age or chronic stress. Adjustment involves interventions, including hormonal replacement or metabolic modulators, to restore the setpoint to a more youthful, higher-functioning value.
