Addison’s disease (also Addison disease, chronic adrenal insufficiency, hypocortisolism, and hypoadrenalism) is a rare, chronic endocrine system disorder in which the adrenal glands do not produce sufficient steroid hormones (glucocorticoids and often mineralocorticoids). It is characterised by a number of relatively nonspecific symptoms, such as abdominal pain and weakness, but under certain circumstances, these may progress to Addisonian crisis, a severe illness which may include very low blood pressure and coma.<br>See also : [[Cushing’s Syndrome]]

The National Endocrine and Metabolic Diseases Information Service states that Addison's disease occurs in 1 to 4 people in every 100,000, and that it can develop in people of all ages and sexes. There are numerous symptoms associated with this condition, although some of the most common include prolonged fatigue, muscle weakness, reduced appetite, reduced body weight, nausea and vomiting. If you have Addison's disease, you may also experience low blood pressure, diarrhea and excessive sweating.
