Addison's disease, also known as hypoadrenocorticism, is a chronic condition in which the adrenal glands produce insufficient cortisol. It is the opposite of Cushing's disease.
The adrenal glands produce two types of hormones; we're most familiar with the glucocortoid ones, such as cortisone. Cortisol and other hormonal levels rise during anger or fear, stress or injury. The term "getting one's adrenalin going" in response to these situations applies to the natural response a healthy body has to them. Those with faulty adrenal glands don't produce enough cortisol to allow the body to respond properly.

The other adrenal hormones, known as mineralcorticoids, are what keeps the system in balance regarding proper amounts of salt, potassium, and water in the body. Imbalances of these keys to life can have grave consequences also.
