Research Progress on the Etiology and Pregnancy Outcomes of Thrombocytopenia During Pregnancy

Thrombocytopenia during pregnancy is a common hematological abnormality with complex and diverse etiologies, involving physiological changes during pregnancy, immune factors, genetic factors, and other underlying diseases. Based on etiology, thrombocytopenia during pregnancy can be classified into pregnancy-specific and non-pregnancy-specific categories. The impact of thrombocytopenia caused by different etiologies on pregnancy outcomes varies. This article reviews the common etiologies of thrombocytopenia during pregnancy and related research progress on pregnancy outcomes, aiming to provide a theoretical basis for early clinical identification, diagnosis, and appropriate intervention to improve maternal and fetal prognosis.
