Hypothyroidism caused by Hashimoto’s thyroiditis can be considered if you have an unwanted pregnancy, but you need to adjust the level of thyroid hormones in time so that it can reach the standard quickly and reduce the impact on the fetus. Hashimoto’s hypothyroidism should be adjusted to normal thyroid function in normal times, and if the thyroid function is normal at the time of pregnancy, the pregnancy can be normal. If the pregnancy is still in a state of hypothyroidism, the dose of thyroid hormone should be increased immediately after the discovery of the pregnancy in order to supplement the thyroid hormone and to prevent any effect on the growth and development of the fetus. It is important to seek medical attention to adjust the value of thyroid hormone.
