What should be done if a pregnant woman has low thyroid-stimulating hormone?

Patient's question:

No

Doctor's answer:

This situation does not have a significant impact on fetal development, as long as T3T4FT3FT4 are normal, there will be no effect. As for thyroid-stimulating hormone, it only acts indirectly on the thyroid.
Advice: It is currently believed that there is no problem and it will not affect fetal development. As long as T3T4FT3FT4 are normal, fetal development is guaranteed, and there is no need to worry.
