Cortisol Metabolism ∞ Area

Cortisol Metabolism

Meaning

Cortisol metabolism involves the synthesis, secretion, transport, cellular action, and eventual degradation and excretion of cortisol. This primary glucocorticoid, produced by the adrenal cortex, precisely regulates numerous bodily functions.

Context

Regulated by the HPA axis, cortisol metabolism operates within a neuroendocrine feedback system. Cortisol circulates, largely protein-bound, influencing target tissues. Its diurnal rhythm is essential for metabolic and immune system balance.

Significance

Understanding cortisol metabolism is crucial for clinical assessment of stress adaptation, metabolic health, and immune function. Dysregulation manifests as fatigue, mood changes, or adrenal disorders. Evaluating cortisol dynamics offers key diagnostic insights, informing therapy.

Mechanism

Cortisol is synthesized from cholesterol in the adrenal cortex via enzymatic conversions. It acts by binding to intracellular glucocorticoid receptors, modifying gene expression. Inactivation occurs mainly in the liver and kidneys through 11β-hydroxysteroid dehydrogenase, converting active cortisol to inactive cortisone for elimination.

Application

Clinically, knowledge of cortisol metabolism guides diagnostic protocols for adrenal dysfunction and informs treatment strategies for inflammatory conditions and chronic stress. Therapeutic synthetic glucocorticoids require careful consideration of impact on endogenous production. Lifestyle interventions also support healthy cortisol rhythms.

Metric

Assessment of cortisol metabolism typically involves various laboratory tests. Serum cortisol levels, often timed, provide a snapshot of circulating hormone. Salivary cortisol testing offers a non-invasive measure of unbound, active cortisol, valuable for diurnal rhythm evaluation. Twenty-four-hour urinary free cortisol quantifies daily excretion, aiding diagnosis.

Risk

Imbalances in cortisol metabolism present significant health risks. Chronically elevated cortisol, as in Cushing’s syndrome, can lead to metabolic dysregulation, immune suppression, and bone loss. Conversely, insufficient cortisol, as in Addison’s disease, causes severe fatigue, hypotension, and electrolyte disturbances, potentially causing adrenal crisis. Exogenous glucocorticoid use risks HPA axis suppression.
