To our knowledge, this is the first case report of hypoglycemic unawareness subsequent to cardiac failure induced hypoglycemia of prolonged duration. Through this case report, we aimed to highlight that hypoglycemia should be suspected as a cause of decreased level of consciousness in patients suffering from recurrent congestive cardiac failure , as it can be easily overlooked and the condition can easily be reversed by simply administering adequate glucose. https://crcp.tums.ac.ir/index.php/crcp/article/view/240 https://crcp.tums.ac.ir/index.php/crcp/article/download/240/292
