I wanted to share an update – 6 years since my 2015 update earlier in this thread.
Between that time and through late last year my wife’s thyroid levels were stable when got pregnant with our first child. Because of the Graves she was referred to maternal fetal medicine as a high risk patient where they recommend extra growth scans for possible growth restriction.
Our son did come out “small for gestational age”, but happy and healthy. His thyroid levels were tested at birth and his TSH was low (t4 in range). But further testing showed no Graves antibodies and that his TSH came back into the normal range.
My wife’s endocrinologist also did a great job staying on top of the need for higher doses of Synthroid as the pregnancy progressed.
Mom is currently ramping down the Synthroid levels and is back on the hunt for the right dose.
