I've asked this question before. I have recently increased my Levo from 75mcg to 100. I'm also on 20mcg T3. However, as soon as I increased I became constipated and within a week my skin became drier. This was 3 weeks ago.
TSH: 0.01 (0.27 - 4.20) FT4: 17.9 (12.00 - 22.00) FT3: 5.2 (4.00 - 6.80)
Prior to this my FT4 was 11.4 TSH and FT3 was the same.
I saw the endo today and he couldn't offer an explanation but said that I had to decrease my thyroid meds because of TSH. I don't want to do this and I explained to him I have increased because I'm hypo.
Could I have RT3? Or could there be another explanation?
