At present, attention to thyroid disease during pregnancy is increasing at home and abroad, but there is relatively little concern about postpartum thyroid disease, especially high incidence of postpartum thyroiditis (PPT). This observational study is to investigate the relationship between different levels of thyroid peroxidase antibody (TPOAb) and postpartum thyroiditis (PPT) in early pregnancy (1-12 weeks of pregnancy), and to explore whether PPT can be predicted by different TPOAb levels. According to the TPOAb level in early pregnancy, the postpartum of pregnant women was followed up, PPT was detected early, and intervention was performed according to thyroid dysfunction.
