FAQ
Frequently asked questions
What is the role of ACTH in the body?
ACTH is a hormone released by the pituitary gland in the brain. Its primary role is to stimulate the adrenal glands, located on top of the kidneys, to produce and release cortisol.
How does ACTH relate to cortisol?
ACTH acts as a messenger, telling the adrenal glands when to make and release cortisol. High ACTH levels often indicate the adrenal glands are being stimulated, while low levels suggest less stimulation.
Can ACTH levels change throughout the day?
Yes, ACTH levels naturally fluctuate throughout the day, often following a circadian rhythm. Levels are typically highest in the morning and decrease as the day progresses.
What might cause abnormal ACTH levels?
Abnormal ACTH levels can be caused by issues with the pituitary gland (which produces ACTH) or the adrenal glands (which respond to ACTH). Conditions affecting these glands can lead to either high or low ACTH.
