Pregnant women with high thyroglobulin antibodies need to have their thyroid function checked, i.e. free T3, free T4 and TSH, to see if there are any problems with these three, and if there are no problems with these three, no treatment is needed. However, it is recommended that pregnant women be checked 2-3 times during the early, middle and late stages of pregnancy to see if there are any changes in thyroid function. If there is no change, there is no damage to the pregnant woman or the baby for the time being. If the thyroid hormone is high, you need to seek timely treatment from your doctor to see if it is hyperthyroidism, hypothyroidism or other conditions. If the TPOAb is high, there is no problem with the thyroid function, and the diet does not need to be deliberately required. If the TPOAb antibody is high when you are not pregnant, a low iodine diet is recommended, but pregnant women need iodine and low iodine is not good for the baby, so as long as the function is normal, there are no deliberate dietary requirements.
