Hypothyroidism detected at 26 weeks of pregnancy needs to be taken into account before deciding whether the child can be wanted or not. At 26 weeks of pregnancy, you are already in the middle of the pregnancy and the child is basically well-developed. If you are newly diagnosed with hypothyroidism, it is recommended to use medication to control your thyroid function and keep it within the normal range. If the medication controls the thyroid function well and the baby develops normally, you can consider continuing the pregnancy. If the control of thyroid function is not very good after using medication, it is necessary to consult an endocrinologist to help adjust the medication, because the persistence of hypothyroidism will affect the child’s intellectual development, and in serious cases, there will be cretinism, and even the child’s physical defects, and at the same time, we should pay attention to do a good examination of malformations, and if there is a combination of serious malformations, it is necessary to terminate the pregnancy if necessary. Some pregnant women have a simple decrease in free thyroxine, which is generally not a big problem, and they can continue the pregnancy and pay attention to regular checkups. If there is a combination of elevated thyroid stimulating hormone, it is necessary to timely use medication to adjust. In life, we should pay attention to regular diet, ensure nutrition, appropriate eating seaweed, nori and other high iodine food.
