My mom has Grave's disease and had a total thyroidectormy about 2 years ago. For the past 2 years, her TSH has mostly been in the mid range, borderline low T3, and normal T4.
The last few weeks, she is having symptoms of atrial fibrillation and fluctuating blood pressure (just like symptoms she had few years ago with hyperthroidism before total thyroidectomy).
Some numbers here from past couple of months ...
Oct 15th -
TSH 2.36 (0.34 - 4.82)
T4 Free 16.3 (10.0 - 20.0)
T3 Free 3.3 (3.5 - 6.5)
November 19th - (different lab than Oct 15)
TSH 3.79 (0.27 - 4.20)
T4 Free 22.6 (12.0 - 22.0)
T3 Free Not tested
--> Dec 1 to Dec 3 - reduced Synthorid dose 50% (75mcg normally) due to frequent episodes of atrial fibrillation
Dec 3rd -
(same lab as Oct 15th)
TSH 0.04 (0.34 - 4.82)
T4 Free 16.9 (10.0 - 20.0)
T3 Free 6.4 (3.5 - 6.5)
Any insights and help would be greatly appreciated! We are waiting to hear from endo.
