Chronic psychological stress is the most potent activator, keeping the system in a persistent state of alert. 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.
Long Term Effects Of ACTH Axis Stress
Its primary function is to stimulate the adrenal glands to produce and release cortisol. This self-regulating mechanism ensures that cortisol returns to baseline once the stressor is resolved.
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. In this procedure, synthetic ACTH is injected, and subsequent cortisol levels are measured.

This signal travels directly to the anterior pituitary, triggering the synthesis and release of adrenocorticotropic hormone (ACTH) into the systemic circulation. Beyond cortisol, ACTH also promotes the synthesis of adrenal androgens, such as dehydroepiandrosterone (DHEA), which serve as precursors for sex hormones.
