Question
Do O-type blood women experience adverse effects during pregnancy?
Answer
O-type pregnant women may be prone to hemolytic reactions, which are usually related to their partner’s blood type. If the woman is O-type and her partner is A-type or B-type, ABO hemolytic anemia may occur due to the mother’s antibodies not matching the baby’s blood type. This type of hemolytic reaction typically occurs in the first pregnancy, and the chance of it happening again in subsequent pregnancies is lower if the baby’s blood type is the same. Fetal umbilical cord blood tests can be conducted during pregnancy to determine if there is any hemolytic condition, and if the baby develops jaundice after birth, the possibility of hemolytic anemia should also be considered. It is recommended to consult with a professional at a reproductive genetics center before pregnancy.
