妊娠合并甲状腺功能亢进症的诊治

Diagnosis and management of hyperthyroidism during pregnancy

妊娠合并甲状腺功能亢进症(甲亢)的发生率为0.1%～0.2%。最主要的病因是Graves病,是一种自身免疫性疾病。妊娠结局与是否治疗和严重程度有关。妊娠期甲亢的诊断有一定难度,游离T3或T4的水平升高,伴TSH水平降低能确诊为甲亢。一般是选择抗甲状腺药物治疗。

Thyrotoxicosis, or hyperthyroidism complicates about 0. 1% - 0.2% pregnancies. The over- whelming cause of thyrotoxicosis in pregnancy is Graves＇disease, an organspecific autoimmune disease. Pregnancy outcomes in thyrotoxic women depend upon whether metabolic control is achieved. Mild thyrotoxieosis is difficult to diagnose during pregnancy. Clinical hypothyroidism is diagnosed if free thyroxine levels are low and the thyrotropin level is elevated. Thyrotoxicosis during pregnancy is generally treated medically.
