Physical stressors, such as illness, surgery, or intense exercise, also demand a hormonal response. 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.

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 secretion of ACTH is not constant; it follows a distinct circadian rhythm, typically peaking in the early morning to promote alertness and tapering off towards the evening to facilitate sleep.
The process begins in the hypothalamus, which releases corticotropin-releasing hormone (CRH) into a specialized blood network. Cushing's syndrome results from prolonged exposure to high cortisol levels, often due to a pituitary tumor secreting excess ACTH or an adrenal tumor.

The Role of ACTH Adrenocorticotropic hormone (ACTH) is the critical intermediary in this physiological cascade. Clinical Significance and Diagnostic Approaches Dysfunction within the ACTH axis manifests in several clinical disorders.
