Whether or not you still need to take medication if your thyroid stimulating hormone is normal in pregnancy should be determined by your specific condition. For example, pregnant patients with hyperthyroidism (hyperthyroidism) may need to continue taking medication after their thyrotropin is normalized. Serum free thyroxine/total thyroxine is the primary monitor for hyperthyroidism control during pregnancy, not thyrotropin, because normalizing serum thyrotropin may result in lower thyroxine levels. For patients with hyperthyroidism in pregnancy after drug treatment, thyrotropin levels return to normal is not an indicator of discontinuation, may still need to continue to take medication, and regular review, under the guidance of the doctor to adjust the dose of medication according to the level of thyroid hormone. If you have a normal thyroid stimulating hormone level in pregnancy and are not sure whether you need to take medication or not, you can go to the hospital and consult a professional doctor.
