Abstract:
Sheehan's syndrome has been attributed to ischemic damage of the pituitary gland or hypothalamic-pituitary stalk during the peripartum period. Well-described clinical features of Sheehan`s syndrome include hypothyroidism, growth hormone deficiency, hypogonadism, hypoprolactinemia, adrenal insufficiency, and different sodium and water disturbance. The occurrence of sodium and water disturbances associated with Sheehan`s syndrome depends on the degree of pituitary damage, time of onset since the initial pituitary insult, and concurrent medical conditions that also may play a role in sodium and water balance. Chronic hyponatremia is the most common presentation of altered sodium levels in patients with Sheehan`s syndrome. The chronic nature of the presenting hyponatremia suggests more subtle changes of panhypopituitarism or better adaptive mechanism. Although controversial, another mechanism proposed for hyponatremia in the chronic setting involves alternation in the renin-angiotensin/aldosterone system with resulting sodium wasting. We presented a patient with Sheehan`s syndrome associated with hyporeninemic hypoaldosteronism and hyponatremia 53 years old women, who had 4th baby delivery with severe blood loss about 25 years ago, was admitted to hospital because of general weakness. The patient was diagnosis Sheehan`s syndrome with hyponatremia. In addition, we performed hormonal study to find cause of hyponatremia. The results were hypopituitarism and hyporeninemic hypoaldosteronism. Hyponatremia was corrected by hormonal therapy (glucocorticoid,synthyroid,estrogen). The patient felt well-being sensation and was followed up the out-patient department.
