The symptoms of chronic adrenal failure have a very gradual onset, so that the condition is difficult to appreciate. Lack of energy, malaise (a feeling of general discomfort or uneasiness), or giddiness when standing up, are almost always present. There is usually an increase in skin pigmentation. Often, the development of an intercurrent illness decompensates the condition which suddenly deteriorates into circulatory collapse, hypoglycaemia (low blood sugar) and, if untreated, death.
Addison's disease, first described in 1849 by Dr T Addison, is a rare condition which is due to the destruction of the adrenal cortex leading to a deficiency or absence of cortisol and other adrenal hormones. The symptoms are due to the failure of the production of cortical hormones, which are responsible for the rate at which sugar is made available to the tissues of the body, and the amount of salt lost from the body.
