If you are found to have Hashimoto’s thyroiditis in the third trimester of pregnancy, you can have the baby. Hashimoto’s thyroiditis is a chronic autoimmune thyroid inflammation that progresses relatively slowly. The key to finding out if Hashimoto’s thyroiditis in the third trimester of pregnancy will have an effect on the pregnancy also depends on whether it has caused abnormal thyroid function. If the thyroid function is normal and you have Hashimoto’s thyroiditis during pregnancy, you generally don’t need special treatment, but you need to go to the hospital regularly for thyroid function tests, and try to eat less food that is high in iodine, such as kelp, seaweed and nori. If Hashimoto’s thyroiditis has caused hypothyroidism, it is necessary to use medication to regulate in time, otherwise it may adversely affect the fetus. In this case, you can take levothyroxine sodium tablets and other drugs under the guidance of the doctor, and pay attention to review the thyroid function.
