Hi, I had a blood test 3 months ago with a TSH result of 6.1. The doc said I needed a further test in 3 months which I have just got the results for. My TSHis 5.75, antibodies 36 and free T4 15.3. The doc had not checked the results yet, I got the figures from the receptionist. I have lots of symptoms that seem to be worsening and I have been researching thyroid issues before I go back to the docs. My paternal aunt had an under active thyroid as well as coeliac disease (which is an auto immune disease) and my daughter also had coeliac disease. Have you any advice before I speak too my doctor? I think I have under active thyroid but don't think the levels are extreme enough for the doc to treat.
