Medication not working

Hi all,

I have been struggling with fatige, cold, dry hair for years. My free T3 T4, are at the high end. In my country we dont have tests for RT3. I have realy high cortsol 1200 (200-700) and i was wondering if that could be the resone for the medication is not working (T4). Read that high cortsol would make RT3 high!!

Do you think Adding T3, would be helpful?

Please post your FT3 and FT4 results with reference ranges.  We can then better answer your question of whether adding T3 might help.

First member I can recall from Iceland.  Welcome to the Forum.

High cortisol will adversely affect thyroid metabolism.  High cortisol is reported to cause excess conversion of T4 to Reverse T3, which can result in a ratio of Free T3 to Reverse T3 that is too low.

What thyroid medication are you taking and what dosage?  

Also, hypo patients frequently find that they are too low in the ranges for Vitamin D, B12 and ferritin.  If you have been tested for those, please post results and their reference ranges.

Even more important than test results are symptoms.  Please tell us about all the symptoms you are having that cause you to feel so bad.  

Also, please post the actual results and reference ranges for the Vitamin D, B12 and ferritin.  

When were you were originally diagnosed as hypothyroid?   What was identified as the cause?  Was it possibly Hashimoto's Thyroiditis? How long have you been taking the 75 mcg of T4 med?  When were those tests done?
