I’m so sorry to hear you are dealing with all of this after delivering your baby!!

I would not make any changes in endocrinologist at this time. I would follow treatment plan for thyroid medication and RAI and stop breastfeeding at this point. Endocrinologists may be limited in their knowledge/training on RAI in pregnancy/postpartum and with breastfeeding. They can continue to monitor bloodwork and thyroid hormone levels plus other hormones and make sure you get regular ultrasounds of your neck despite having your thyroid removed. You can get thyroid cells regrowing in your neck after full thyroidectomy. My sister had a full thyroidectomy at 27 when they found cancer and Inhad a lobectomy in my 50s due to a suspicious large nodule (I now an hypothyroid and have Hashimoto’s thyroiditis confirmed).

You may want to talk to your OBGYN and consult a breast health expert about RAI and breastfeeding risks post treatment. Your baby may need to stay on formula and your breastmilk will stop if not regularly breastfeeding/pumping. The RAI may be too risky for you and your baby to breastfeed. Don’t put too much pressure on yourself because all of this is a lot to deal with after delivering a baby and having thyroidectomy/RAI. Take care of you and your baby as best you can with the help of your friends and family.
