Causes of high TSH in pregnancy is the mixing of estrogen and human chorionic gonadotropin, in short HCG, hormones secreted into the body during pregnancy. When these hormones enter the blood, a decrease or increase in TSH level can be observed. Since the effect of the HCG hormone in the body is similar to the TSH hormone, it may increase the thyroid hormone or create an adverse effect, causing the thyroid hormone to be secreted much higher or less than it should.
Treatments applied in order to reduce TSH elevation during pregnancy are carefully selected and ways that do not endanger the health of the baby are taken. In general, it is possible to reduce the TSH height with medication.
