Thyroid Diseases

Out of normal range TSH and pregnancy



Hi, I am 29 yrs old female, married for 1.5 yrs. I am on thyroid medication (thyronorm 50)since last 8-9 mnths. My TSH levels keep on fluctuating between 2-6, recent level being 5.58. T3 and T4 are in normal range. Pelvic Sonography report is normal. My physician thinks that it is ok for me to try for conception. But my concern is that if i do conceive, would my child have any mental or visual defects because of my high TSH? What precautions would I need to take? Please guide.


TSH levels always fluctuate to some degree. It is recommended that you take enough thyroid medication to keep your TSH in the low normal range. It is believe that this minimizes the risk of miscarriage. Borderline hypothyroidism (mildly elevated TSH) does not increase the risk of birth defects.
