Hello - I recently had lab work done, and am waiting for a follow up to discuss with my endo. In the mean time, I'm looking for other insights, and would greatly appreciate any help. I have no thyroid tissue left after two doses of RAI (5 years ago), and after stable treatment on Levothyroxine since 2004, I recently started having many hypo symptoms. TSH in December was around 5.5, then down to 1.5 in January after an increase from .125 to .15 in Levothyroxine (fasting, no meds), and my recent results are below. I had already taken my levothyroxine that day (5 hours prior to labs). I'm also on long term corticosteroids (15+ years), and birth control pills. I'm 33/Female/not pregnant.
My question is, although TSH is in normal range, I'm still experiecing many hypo symptoms - is it my thyroid, or adrenal fatique, or something entirely different? Thanks in advance for any help you can provide.
