Hypopituitarism as a Rare Cause of Hyponatremia

Abstract

Hypopituitarism is defined as pituitary hormone (or hormones) deficiency caused by dysfunction of pituitary gland and/or
hypothalamus. Clinical findings and diagnostic procedure depend to the deficient pituitary hormone. The prognosis of patients with hypopituitarism is associated with presentation, age, the degree and severity of the hormonal disorder, and the response to medical and surgical treatment. In present case, we report a 78 years old woman that presented with hyponatremia, nausea and vomiting, whom consequently diagnosed with hypopituitarism and we discussed diagnostic procedure to establish the diagnosis. In sake of prevention of mortality, physicians should be aware of hypopituitarism in subjects with nausea, vomiting and electrolyte disturbances. Once the diagnosis established, replacement therapy should be initiated immediately.
