Hi Dr. Lupo,
I was diagnosed with Hypothyroidism (Hashimoto's...although there were never any antibody tests performed) in Sept. 07 and put on 75mcg of Synthroid. I never told my Dr. this because I didn't know it could be a cause until recently: but I was approx. 2 months pregnant and had a miscarriage 6 months prior to being diagnosed Hypo. I recently had blood work done on my own out of curiousity and my results are listed below:
T3 Uptake: 35%
Thyroxine (T4): 9.4 (normal 4.5 - 12.0)
Free Thyroxine: 3.3 (normal 1.2 - 4.9)
TSH: 0.156 (normal .350-5.500)
I have read that PPT can eventually go away, It has been a year now since the pregnancy, based on the fact that my dosage has remained constant but I am suddenly Hyper, do you think it is likely that the disease is subsiding? What do you think the chances are that I have PPT and not regular Hashi's? Along with the above tests, I also had antibody tests done which resulted in:
Thyroid Peroxidase (TPO) Ab: 26 (normal 0 - 34)
Antithyroglobulin Ab: 534 (normal 0 - 40)
It still shows that I have some antibodies, but I thought in order to have Hashi's you must have Thyroid Peroxidase Ab? And mine are within normal range....Should I stop taking Synthroid so that my thyroid has the ability to regain function on it's own and if I continue taking Synthroid will it prevent my thyroid from recovering from PPT?
Thank you so much for your help.
ps. prior to diagnosis I was a completely healthy young female.
