Adrenocorticotropic hormone is produced by the pituitary gland in the brain and plays a central role in the communication between the brain and the adrenal glands. Its main function is to stimulate the adrenal cortex to produce hormones such as cortisol, which regulate blood pressure, blood sugar, and the body’s stress response. This hormone helps the body adapt to stress by increasing alertness and mobilizing energy reserves. Its balance reflects how well the pituitary and adrenal glands function together. Low levels can lead to fatigue, low blood pressure, and poor stress tolerance, while chronically high levels may indicate prolonged stress or adrenal overactivity. Testing this hormone helps assess the health of the pituitary–adrenal axis and diagnose conditions such as adrenal insufficiency or overproduction, making it a vital part of hormonal health assessment.
