The probability of a mother with hyperthyroidism having a healthy baby after the disease has been effectively controlled is relatively high. Most hyperthyroidism patients have a family history of the disease, and babies born to mothers with hyperthyroidism are more likely to have the disease than normal people. If a mother with hyperthyroidism has her condition under control with effective treatment, the hereditary rate of hyperthyroidism is low. If a mother with hyperthyroidism is not effectively treated and becomes pregnant when her condition is severe, her baby may be more affected, resulting in slower growth and mental retardation, and if she continues to take medication during pregnancy, her baby may be deformed, or even have a premature birth, miscarriage or fetal death. When hyperthyroidism is diagnosed, treatment should be carried out promptly under the guidance of a doctor, and anti-thyroid medication or surgery should be actively used to relieve the disease as soon as possible and improve the prognosis. When the disease is cured, you should consult a professional doctor before preparing for pregnancy and take regular pregnancy tests during pregnancy to ensure the healthy growth of your baby.
