I'd be very grateful if anyone can help me understand why my results look worse after an increase in levo and also if anyone has any thoughts about my next dose increase.
Brief context: I've been on the same dose of levo for c4 years, and each time I've tried to increase in the past, I've been unable to function. After receiving particularly poor test results in May, I've been increasing in six-week increments, with a very small increase each time, which I've managed to tolerate.
I'm now puzzled by the drop in my latest results following a dose increase. My previous set of results (19/7/21) were:
TSH: 1.96 (0.27-4.2)
FT4: 19.4 (12-22)
FT3: 4.6 (3.1-6.8)
I increased my dose at this point from 75mcg per day to 5x75 and 2x100 levo.
My latest results (21/9/21) are:
0.95 (0.27-4.2)
FT4: 18.1 (12-22)
FT3: 3.6 (3.1-6.8).
Both tests were taken at the same time, 0800hrs, no levo the night before, and nothing to eat or drink.
I feel pretty lousy, but (a) I've had chronic fatigue for the past 14 years or so - several years before my thyroiditis was diagnosed - and (b) I've never had the typical thyroid symptoms of weight gain and cold body temperature, so I always struggle to know which symptoms are because of thyroid. I also managed to catch Covid back in February 2020 and have never felt well since. All of that said, I'm sure from my FT3 result that I need to increase levo further, but after this fall in FT3 and FT4, I'm a bit stuck what to do.
In case it's helpful, my tests from 4/5/21, when I was on 4x75 and 3x50 levo:
TSH: 3.29 (0.27-4.2)
FT4: 17.0 (12-22)
FT3: 4.3 (3.1-6.8)
Vitamin D: 102 (75-175)
Ferritin: 91 (13-150)
Folate: 25.7 (8.83-60.8)
Active B12: >150 (37.5-188).
Thanks so much for any help anyone can give me.
