Cushing's Disease is a condition characterized by excessive production of cortisol, a steroid hormone, due to a tumor in the pituitary gland. This tumor leads to an overproduction of adrenocorticotropic hormone (ACTH), stimulating the adrenal glands to produce more cortisol than the body needs. This condition falls under the broader category of Cushing's Syndrome, which can result from various causes, including long-term use of corticosteroid medications or adrenal tumors.
