Relationship between T4 and T3 in Hashimoto's
When I look up this issue online I can't find much to explain why my T4 number 5.6, is normal according to LabCorp, and my T3 (free) ,4.8 is high. According to the lab it should be no higher than 4.4. My free T4 is .85 which is at the low end of the scale. Since my TSH is 5.00 I guess it is struggling to churn out hormones on my NP thyroid dosage of 60 mg but I have been told that increasing the NP thyroid dosage to decrease the TSH would be a mistake because it would increase my T3 (Free) making me hyperthyroid. So, could this be an adrenal problem? If so would increasing cortisol help?
