Causes of Addison's disease
Addison’s disease is the result of the destruction of the adrenal cortex.
In about 70% of cases Addison’s disease is an autoimmune condition. This means that the destruction is caused when the body’s own immune system attacks the adrenal cortex as if it were a foreign implant. The cortex becomes inflamed (swollen) and the outer layer shrinks.
The other 30% of cases are caused by infections such as tuberculosis, tumours or other diseases of the glands.
