Antibodies to the thyroid gland during breastfeeding and pregnancy. Is there any harm?

An increase in AT-TPO and AT-TG can alarm women in the event of pregnancy or breastfeeding. Are they harmful to the fetus and baby? After all, not without reason, they are called “antibodies”.

In fact, the term antibody is the second synonym for immunoglobulins, i.e. immune proteins.

Antibodies do not harm the thyroid gland of the mother and child! Some of them (AT-TPO) inhibit the activity of tired (exhausted) gland cells. Other antibodies (AT-TG) are involved in the removal of destroyed follicles.

Important arguments:

1. Since the child’s thyroid gland has neither depleted nor destroyed cells, the mother’s antibodies, acting in smaller amounts through the placenta (during pregnancy) or with breast milk (when breast-feeding) do not have an effect on the baby’s gland tissue.

2. Milk enters the digestive tract, not blood. Therefore, it is not easy for antibodies to the thyroid gland to penetrate the child’s bloodstream.

3. During pregnancy, a sufficient amount of thyroid hormones goes to the baby from the mother and partly from its gland. Antibodies do not harm this process. Therefore, the development of the unborn child with a sufficient amount of hormones occurs optimally.

4. Antibodies are rapidly removed from the blood, when it is filtered in the kidneys (in the urine).

5. In women with an increased amount of antibodies, babies are born without hypothyroidism and autoimmune diseases if during pregnancy the level of thyroid hormones in the mother was in the optimal part of the norm.
