My thyroid is doing strange things & iron update

I went a week ago and had my pre-thyroid appointment bloodwork done.  This included my newest iron studies that were done after taking the Rx strength iron for the last 3 months.  Being the impatient patient that I am I was unwilling to wait the week until my appointment so I called my endocrinologist.  She said that my thyroid labs came back kinda funny and she was confused.  My TSH was up to 1.08 (the highest it’s been in a long time) but that my free T4 was off which it’s never been.  She wanted to know if I was willing to have it repeated a few days before today’s appointment.  So I did.  Today the T4 was back to normal but my TSH was 0.26!  She said she had never seen anyone’s TSH change so much in 1 week.  Mine had done this once before too.  She isn’t sure what to make of it.  My last ultrasound a month ago showed that there are no more nodes on it either.  Strange.  But I am full of hyperthyroid symptoms again…………..lovely as they are.  Except that I’m gaining weight this time.  Probably because my appetite is out of control though.  So, the plan for now is to check it again.

On to the iron studies:  my ferritin was 7 three months ago and now it is a whopping 12.  Major greatness after 3 months of oral iron therapy!  Off to call my primary to see what to do about it now.
