I've been having some issues since I went to the doctor in July due to 10-15lbs of weight gain in 2 months, and extreme fatigue. At the time, I tested positive for pernicious anemia (although that's changed), which explained the fatigue but not the weight gain. My GP said that my thyroid was normal. Towards the end of July, these were my results:
TSH 2.52 uIU/mL, range 0.450-4.500
-Triiodothyronine,Free,Serum, 3.30 pg/mL , range: 2.0-4.4
-T4,Free(Direct)1.10 ng/dL, range: 0.82-1.77
Now, my TSH is 3.23 and T3/T4 allegedly in normal range (my doctor didn't provide those for some reason) and I tested negative for the "thyroid antibody." My doctor sent these results by email, so I don't have further details on that. I haven't gained any additional weight, but I also haven't been able to lose weight, no matter how I change my diet, which is really frustrating. Because the fatigue hasn't gone away, I haven't really been able to exercise.
I know that my TSH in July was in the 95th percentile of healthy people, as some really helpful people on here pointed out before. It's gone up again, and seems farther from a true normal, even though my doctor said it's still in the normal range. I don't know how my T3/T4 have changed, although again my doctor said those were normal.
Has anyone experienced this? Or have any thoughts on if this increase is normal? My GP wants me to come back in another 6 months to retest these, but I'm nervous I'll gain more weight or feel worse.
