Cushing disease  listen  (KUSH-ing dih-ZEEZ)

  A condition in which there is too much cortisol (a hormone made by the outer layer of the adrenal gland) in the body. In Cushing disease, this happens when an adenoma (benign tumor) in the pituitary gland makes too much adrenocorticotropic hormone (ACTH). This causes the adrenal gland to make too much cortisol. Symptoms include a round face, thin arms and legs, severe fatigue and muscle weakness, high blood pressure and high blood sugar, purple or pink stretch marks on the skin, and weight gain, especially in the abdomen.
