Pregnant women may experience mild hyperthyroidism due to physiological periods and special times that may cause a further increase in thyroxine demand. The presence of hyperthyroidism need not be overly examined, as most of it is due to physiological factors. For mild hyperthyroidism that develops during pregnancy, exogenous thyroxine supplements, including thyroxine tablets or eugenol medication, can be taken to relieve and treat hyperthyroidism caused during pregnancy. For insignificantly elevated indicators, they can also be appropriately mediated by appropriate means such as food or diet, both of which contribute to the safety of the pregnant woman as well as the fetus. If the disease is difficult to improve or not effectively relieved, you should go to the hospital for a detailed examination and choose an appropriate treatment plan in time.
