    ### Instruction:
    What are the treatments for Graves' Disease ?
    ### Response:
    Treatment for Graves disease can sometimes affect pregnancy. After treatment with surgery or radioactive iodine, TSI antibodies can still be present in the blood, even when thyroid levels are normal. If a pregnant woman has received either of these treatments prior to becoming pregnant, the antibodies she produces may travel across the placenta to the babys bloodstream and stimulate the fetal thyroid.
