Cushing's syndrome is the result of the excessive production of corticosteroids by the adrenal glands. An overproduction of corticotropin (ACTH) - the hormone that controls the adrenal gland - by the pituitary gland, which stimulates the adrenal glands to produce corticosteroids, may be one cause. It is called Cushing's disease and the result of ACTH-secreting pituitary adenoma. Alt.
