Some patients have a similar condition known as Cushing's disease, which is caused by a tumor in the pituitary gland. The most common cause of Cushing's Syndrome is a benign adenoma (tumor) in the adrenal gland that produces too much cortisol. Women are three times more likely to be affected than men. The adrenal medulla is derived from nerve cells and is a source of catecholamines (adrenaline and noradrenaline), which are “stress hormones” that increase alertness, strength and speed in an emergency.Ĭushing's Syndrome is characterized by the overproduction of cortisol, a hormone released by the adrenal glands that aids in stress response and maintains blood pressure and heart function, among other things, although it goes undiagnosed in many people. ![]() ![]() The adrenal cortex produces steroid hormones that maintain blood pressure and salt balance.
