Precautions for pregnancy with blood type O

Blood shape is also related to pregnancy, and many people may not understand the relevant content. If the pregnant woman has type O blood, she should be examined before pregnancy and childbirth, and some measures can be taken to prevent hemolysis. So, if you are already pregnant, are there many common problems? Let's get to know each other and see what pregnant women with type O blood should pay attention to?

What should pregnant mothers pay attention to if they have blood type O

This is because for pregnant mothers, the blood types of maternal and child products are inconsistent. The most common situation is that the mother's blood type is O type, while the baby's blood type is A or B type. In fact, this kind of blood type inconsistency is not uncommon during pregnancy.

In addition, the blood types of mothers and babies also do not match the RH type. In other words, the expectant mother's blood type is negative, while the baby's blood type is positive. The mother may produce antibodies due to RH allergy, and this antigen enters the fetal blood through the embryo and causes hemolysis. This is a hemolytic disease caused by the incompatibility of blood shapes between the expectant mother and the fetus, which usually occurs during the fetal period and early infancy. Therefore, if you are an expectant mother with type O blood, you must pay attention to this test during pregnancy.

If the pregnant mother has type O blood, will the fetus definitely have hemolytic disease?

The answer is not certain. If the pregnant mother is type O blood, the pregnant father is type A, type B or type AB, and the fetus is type A or type B, the blood types of mother and daughter do not match.

For example: ABO hemolysis is a hemolytic reaction that occurs when the mother's blood is type O and the child's blood is type A or type B. The mother's body contains anti-A or anti-B antigens, which enter the fetus's body and destroy the fetus's blood cells, causing hemolysis.

In short, if the pregnant woman has type O blood, the fetus will not necessarily suffer from hemolysis, so we need to pay attention to the father's blood type. In short, women with type O blood must pay great attention to hemolysis before becoming pregnant. Do a check-up before getting pregnant, and get pregnant scientifically under the guidance of a doctor. In this way, the health of the fetus can be ensured, and general hemolytic conditions can be prevented before pregnancy.
