My question: With a positive anti-thyrogloblin and a multinodular goiter, should I continue with infertility treatments or should I continue to wtch and wait for my thyroid to improve? or will it?..... I understand that pregnancy may help my thyroid but my thyroid may actually be keeping me from becoming pregnant...
I'm a 37 year old BMI 24.0 with recent routine blood work as follows:
TSH 0.82 [ 0.34- 5.66]
T4 1.04 [0.52-1.21]
T3 2.88 [2.20- 3.80]
I was then sent for additional blood work and thyroid US since my TSH was on the low end of normal. I have no hypo/hyper symptoms.... though I would love to blame my weight and bad hair on hypothyroidism...( trying to insert humor)
Further values below:
thryotropin receptor AB <0.51 [ 0-1.75]
Thyroid US: Multinodular goiter:
RIGHT LOBE: The right thyroid lobe is heterogeneous. The right lobe
measures 5.7 x 1.4 x 0.6 cm. It contains a solid nodule measuring 1.6 x
1.2 x 0.9 cm.
LEFT LOBE: The left thyroid lobe is heterogeneous and measures 5.4 x 1.2
x 0.9 cm. It contains 2 nodules, the larger of which is complex and
measures 1.7 x 1.0 x 0.6 cm. The smaller, more medial left thyroid nodule
measures 0.7 x 0.6 x 0.3 cm.
Your thyroid hormone levels are normal, but Tg-Ab high. Was TPO-ab tested? The description of "heterogeneity" on ultrasound is consistent with thyroiditis - most commonly due to Hashimooto's in this case. The 1.7cm nodule may require FNA biopsy. There is mixed data/opinion on th erole of using levothyroxine medication for this situation to help decrease miscarriage rate. You should review this w/ your OB and an endocrinologist.
