Abstract

Radioactive iodine treatment (RAIT) after surgery reduces local recurrence and cancer related death. Cases of hyponatremia after preparation for RAIT have rarely been reported. We report 4 cases of hyponatremia which developed after RAIT. The cause of hyponatremia seemed to be related with over ingestion of free water which is recommended during RAIT. These cases highlighted the importance of weight adjusted water ingestion during RAIT.
