My husband was recently treated at the ER for a diagnosis of hypoglycemia. He had not lost consciousness, but couldn't remember what happened the night before. The doctors checked for stroke and/or a TIA, and ruled them out. His blood sugar level was at 177 as he had eaten a brownie for breakfast that morning. I suspect something other than hypoglycemia, such as poor vascular circulation. He has had 2 minor heart attacks, has 2 stints, and is on statins and numerous medications. Can you think of any other reason for a memory lapse such as his? He has never had this before, and it was truly frightening.
