Hi:
I plan on seeing an endocrinologist, but in the meantime...
When I was younger I tested positive for greatly elevated thyroid microsomal antibodies and was borderline hypo. The doctor at the time told me the antibodies were slowly destroying my thyroid.
Some years later, I had thyroid tests ran again, and the levels came back like this...
T4 = 4.3 Normal Range: 4.5-12.5 MCD/DL
Free T4 = 1.01 Normal Range: 0.76-1.79 NG/DL
Free T4 IDX = 1.5 Normal Range: 1.3-4.7
TSH = 2.3 Normal Range: 0.3-5.0 MIU/ML
T3 Uptake = 34.7 Normal Range: 26.0-38.0%
T3 = 1.49 Normal Range: 0.60-1.81 NG/ML
My thyroid microsomal antibodies were in the hundreds at this time and they considered the T4 still borderline hypo, but this doctor stated that I should be monitored for symptoms of HYPERthyroidism.
Throughout the years, I've had the typical symptoms of hypothyroidism (severe cold intolerance, slow metabolism, brittle hair, dry skin, periods of extreme fatigue, etc) but repeated thyroid tests (not sure which ones) had come back normal.
Recently, I started to feel...well, "better" as it not somewhat drained of energy. But I also felt very restless, I've been having some odd muscle twitches, and have found myself in a few "senile moments" lately, though I'm too young to be having them, so I had my thyroid tested and these levels came back..
TSH = 13.3 Normal: 0.3-4.7 mcIU/mL
Free T4 = 1.2 Normal: 0.8-1.6 ng/dl
And that's all that was tested. I've since been put on synthroid.
My question is, is this Hashimoto's Thyroiditis since I have the antibodies? Is this considered euthyroidism or hypothyroidism? My energy levels seem to fluctuate greatly. My thyroid is not visibly enlarged. In addition to cold intolerance (I shiver when it drops to 70F in the house), I also have heat intolerance. Is this possible given the circumstances?
And, could this actually be a problem with my pituitary and not my thyroid problem, since, even though I have the antibodies, I've never caught my T4 levels below borderline low?
