Abnormality of the endocrine system Decreased circulating aldosterone concentration 2008-02-25T10:45:00Z HP:0008184 Abnormally reduced levels of aldosterone. UMLS:C0020595 Decreased aldosterone UMLS:C1846226 Decreased aldosterone production HP:0004319 Aldosterone is a hormone that is produce by the adrenal cortex and that acts on the distal tubules and collecting ducts to favor retention of sodium excretion of potassium, and increased water retention, thereby tending to increase blood pressure. Aldosterone is sometimes called a mineralocorticoid because of its influence on sodium homeostasis. HP:0008190 Mineralocorticoid insufficiency HP:0002924 Hypoaldosteronism Decreased serum aldosterone HP:0000355 Low blood aldosterone level UMLS:C0857899 SNOMEDCT_US:60086000
