It is possible to get pregnant with a high thyroid hormone, but only after the thyroid hormone is restored to normal with treatment. This is because high thyroid hormones can cause hypothyroidism, also known as hypothyroidism. This can lead to irregular menstruation, decreased follicle quality, and even low menstrual flow, which can affect your health. Therefore, the chances of pregnancy are lower than normal, so it is necessary to take oral medication to treat thyroid disorders. When the thyroid stimulating hormone is restored to normal level by oral medication, pregnancy can be carried out at this time. After pregnancy, it is important to take oral medication to avoid the persistence of hypothyroidism, which can affect the intelligence of the fetus and cause preterm miscarriage or preterm birth and even growth restriction.
