How Stress Affects the Adrenal Glands. According to the American Institute of Stress (AIS), stress is one of top causes of poor health in people living in the United States.

Adrenal Stress Index. The adrenal glands are two tiny organs that reside just above the kidneys. Each one weighs about as much as a walnut, but they have a key role in regulating the body's metabolism. Each adrenal gland has two functional zones that have unique jobs in the body. The outer cortex secretes adrenal steroids (Cortisol, DHEA, and Aldosterone). The inner medulla secretes adrenaline and noradrenaline. Cortisol, DHEA, and adrenaline are the three main adrenal stress hormones.
