Due to the high incidence of hemolytic disease, some families who want to have a second child are very concerned about this issue. It can be seen that it is necessary to do a good job in preparing for pregnancy examination, which can make both men and women mentally prepared to welcome their babies. Some parents with type O blood are asking: Can pregnant women with type O blood have a second child?
Can a pregnant woman with type O blood have a second child if both husband and wife are pregnant
If both husband and wife have blood type O, there will be no occurrence of hemolytic disease of the newborn due to ABO blood type incompatibility. It is recommended to check the female's RH blood type again. If it is positive, there will be no occurrence of hemolytic disease of the newborn due to RH blood type incompatibility in the second child. Everyone should be aware that for the first child, cesarean section is used for delivery, and for the second child, it takes at least two years to conceive and give birth. We hope everyone remembers this.
Why do pregnant women with type O blood develop fetal hemolysis
Hemolysis in pregnant women with type O blood is a hemolytic reaction that occurs when the mother's blood type is type O and the child is type A or type B. The mother's body contains anti-A or anti-B antibodies, which enter the fetus and destroy the fetus's red blood cells, resulting in hemolysis. When the fetus inherits the father's blood type gene and the mother lacks this antigen, if maternal immune antibodies enter the fetal blood circulation and bind with the blood type antigen on the child's red blood cells, it can cause hemolytic anemia and jaundice in the child.
Mother son blood type incompatibility does not necessarily lead to hemolytic disease. The incidence of ABO blood type incompatibility is about 20%, but the actual occurrence of neonatal hemolysis is only less than 5%. Mothers do not need to worry too much.
Can a pregnant woman with blood type O have a second child? Since having a first child is no problem, then having a second child should also be no problem. There is a reason for fetal hemolysis, so as long as pregnant women do relevant examinations, have a reasonable diet, and eat nutritious and healthy foods appropriately during pregnancy, it is still very beneficial for fetal development. In addition to these, it is also beneficial for babies to pay attention to rest, avoid too much pressure, and maintain a happy mood.
