Addison disease (or Addison's disease) is adrenocortical insufficiency due to the destruction or dysfunction of the entire adrenal cortex. It affects glucocorticoid and mineralocorticoid function. The onset of disease usually occurs when 90% or more of both adrenal cortices are dysfunctional or destroyed.
Symptoms: Hyperpigmentation, vitiligo, which most often is seen in association with hyperpigmentation in idiopathic autoimmune Addison disease. It is due to the autoimmune destruction of melanocytes. Almost all patients complain of progressive weakness, fatigue, poor appetite, and weight loss. Prominent gastrointestinal symptoms may include nausea, vomiting, and occasional diarrhoea. Glucocorticoid-responsive steatorrhea has been reported.
Meeting a medical practitioner: Physical examination in long-standing cases most often reveals increased pigmentation of the skin and mucous membranes, with or without areas of vitiligo.Patients show evidence of dehydration, hypotension, and orthostatic.Female patients may show an absence of axillary and pubic hair and decreased body hair. This is due to loss of the adrenal androgens, a major source of androgens in women.
