<unk>  is defined as decreased levels of the hormone aldosterone or a resistance of the target tissue to the actions of aldosterone. 
There are several causes for decreased levels of aldosterone, including kidney disorders, adrenal insufficiency, congenital adrenal hyperplasia, and medications such as 
ACE inhibitors, angiotensin receptor blockers, NSAIDs and calcineurin inhibitors. Mutation in the mineralocorticoid receptor gene (NR3C2) may lead to resistance to the actions of the aldosterone.<unk>  results in hyperkalemia, which can be a serious medical condition.  Hyponatremia is unusual in isolated aldosterone deficiency as under normal conditions cortisol inhibits antidiuretic hormone secretion. In patients with adrenal insufficiency as a cause of<unk> , decrease in cortisol, aldosterone, and androgen levels may lead to hyponatremia.<unk>  may be classified into two categories depending on the level of plasma renin and depending on the level of aldosterone. The most common cause of<unk>  is diabetic nephropathy, acute glomerulonephritis, tuberculosis, hemorrhage, infarction, sarcoidosis, AIDS, CMV, and Addison's disease. Less common causes of<unk>  include sarcoidosis, amyloidosis, fungal infections, AIDS complications, and hemochromatosis.Hypoaldosteronism must be differentiated from other diseases that cause hypotension and muscle weakness. Common risk factors in the development of<unk>  include diabetes mellitus, sickle cell anemia, HIV, graves' disease, hypoparathyroidism, hypopituitarism, myasthenia gravis, and pernicious anemia. If left untreated,<unk>  may lead to hyperkalemia and severe muscle weakness. Common complications of<unk>  include hyperkalemia, metabolic acidosis, hypotension, hypovolemia and hyponatremia.  Prognosis of<unk>  is generally good for patients who receive treatment.
