[Review] Clinical features, investigation, and management of Addison's disease

Addison's disease is the manifestation of adrenal glucocorticoid and mineralocorticoid deficiency from T-cell mediated destruction of the adrenal cortex, and is the commonest cause of primary adrenal insufficiency in adults. Due to its vague presentation, diagnosis of Addison's disease is often delayed, and in some cases, individuals present in adrenal crisis. Despite the use of corticosteroid replacement therapy, people with Addison's disease have increased mortality and reduced quality of life.
