ACTHstands forAdrenocorticotropic Hormone
Full Form of ACTH
What is ACTH?
Adrenocorticotropic Hormone (ACTH) is a peptide hormone produced and secreted by the anterior pituitary gland. Its primary function is to stimulate the adrenal cortex to release cortisol, a glucocorticoid hormone essential for stress response, metabolism, and immune regulation. In the Indian medical context, ACTH is critically evaluated in endocrinology for diagnosing disorders such as Addison's disease (adrenal insufficiency) and Cushing's syndrome (excess cortisol). The ACTH stimulation test is commonly performed in Indian hospitals and diagnostic labs to assess adrenal gland function. This hormone is also relevant to conditions like congenital adrenal hyperplasia, which is relatively common in certain Indian populations due to consanguineous marriages. ACTH levels fluctuate diurnally and can be measured via blood tests. For students preparing for medical entrance exams like NEET-PG and AIIMS, understanding ACTH's role in the hypothalamic-pituitary-adrenal (HPA) axis is a recurring topic. Additionally, synthetic ACTH (cosyntropin) is used therapeutically in specific neurological disorders like infantile spasms, though its use in India is limited due to cost and availability. Overall, ACTH is a cornerstone of endocrine physiology and pathology.

ACTH — frequently asked questions
What is the full form of ACTH?
ACTH stands for Adrenocorticotropic Hormone, a hormone produced by the pituitary gland that stimulates the adrenal glands to release cortisol.
What is the ACTH stimulation test used for in India?
The ACTH stimulation test is used to diagnose adrenal insufficiency (Addison's disease) and to differentiate between primary and secondary adrenal disorders.
How is ACTH related to Cushing's syndrome?
In Cushing's syndrome, high cortisol levels may be due to excessive ACTH production (pituitary tumor) or ACTH-independent causes; measuring ACTH helps identify the source.
