Psychogenic polydipsia is characterized by excess thirst, followed by the overconsumption of liquids. This condition is seen in an array of mental illnesses, especially schizophrenia. Psychogenic polydipsia can lead to hyponatremia, which can lead to neurologic sequelae, such as seizures, cerebral edema, and death. In the case under study, the patient presents with schizophrenia, fatigue, weakness, and dizziness during psychiatric follow-up. A comprehensive metabolic panel (CMP) was ordered, which indicated hyponatremia. This patient was treated with salt tablets and behavioral therapy, which led to the normalization of his serum sodium and symptom improvement. The patient has a history of psychogenic polydipsia with hyponatremia, treated on and off for years with salt replacement and water restriction. Management of psychogenic polydipsia is a difficult task. It is important to understand the available management options so that water intoxication and the consequences of hyponatremia do not occur.
精神性烦渴的特征是口渴过度，随后液体摄入过量。这种情况见于一系列精神疾病，尤其是精神分裂症。精神性烦渴可导致低钠血症，进而引发神经后遗症，如癫痫发作、脑水肿甚至死亡。在本研究病例中，该患者在精神科随访期间出现精神分裂症、疲劳、虚弱和头晕症状。于是进行了全面代谢检查（CMP），结果显示存在低钠血症。该患者接受了盐片治疗和行为疗法，血清钠水平恢复正常，症状也有所改善。该患者有精神性烦渴伴低钠血症病史，多年来断断续续接受补盐和限水治疗。精神性烦渴的管理是一项艰巨任务。了解现有的管理方案很重要，这样才能避免水中毒和低钠血症的后果。
