Addison disease is an hormonal (endocrine) disorder involving
destruction of the adrenal glands (small glands adjacent to the kidneys).
In patients with Addison disease, the diseased glands can no longer
produce sufficient adrenal hormones (specifically cortisol) necessary for
the normal daily body functions. The disease is characterized by weight
loss, muscle weakness, fatigue, low blood pressure, and sometimes
darkening of the skin in both exposed and non-exposed parts of the body.
Addison disease affects about 1 in 100,000 people. It occurs in
all age groups and afflicts men and women equally.
