Beyond cortisol, ACTH also promotes the synthesis of adrenal androgens, such as dehydroepiandrosterone (DHEA), which serve as precursors for sex hormones. To further localize the problem, an ACTH stimulation test may be administered.

ACTH then acts upon the adrenal cortex, prompting the secretion of cortisol, the primary glucocorticoid responsible for mediating the body’s long-term stress response. Conversely, the dexamethasone suppression test evaluates the integrity of the feedback loop, where dexamethasone—a synthetic glucocorticoid—should suppress ACTH and cortisol in a healthy individual.
The hypothalamic-pituitary-adrenal (HPA) axis, often discussed in clinical terms as the ACTH axis, represents a cornerstone of human neuroendocrine regulation. Diagnosing these conditions relies heavily on dynamic testing, such as the ACTH stimulation test, which assesses the adrenal glands' ability to respond to ACTH challenge and helps pinpoint the location of the dysfunction within the axis.

Recognizing these triggers is the first step toward restoring balance. Baseline measurements of cortisol and ACTH provide a snapshot of hormonal status.
