Hyponatremia is commonly defined as a serum sodium concentration of 135 mEq/L or less, which is reported to occur in 0.97-2.48% of hospitalized patients. Especially, in elderly patients, severe hyponatremia is sporadically developed without any complaints. Although a variety of causes of hyponatremia are documented, diagnosis of functional adrenal insufficiency is difficult because of a lack of the diagnostic criteria. In this case report, we present five cases of hyponatremia in the elderly, who were presumed to have functional adrenal insufficiency, successfully treated with low doses of hydrocortisone.
低钠血症通常被定义为血清钠浓度为 135mEq/L 或更低，据报道，住院患者中有 0.97-2.48%的人会发生这种情况。特别是在老年患者中，经常会出现没有任何症状的严重低钠血症。虽然已经记录了各种导致低钠血症的原因，但由于缺乏诊断标准，功能性肾上腺功能不全的诊断仍然很困难。在本病例报告中，我们介绍了五例老年低钠血症患者，这些患者被认为患有功能性肾上腺功能不全，使用低剂量的氢化可的松治疗后病情得到了成功缓解。
