What should pregnant women with blood type O pay attention to?

There are different types of blood in the human body, such as type A, type B, type AB or type O, etc. If a pregnant woman is type O blood, people need to pay special attention, because pregnant women with type O blood may have hemolytic disease, which is hereditary and may be passed on to their babies, causing many adverse effects. So here we will introduce 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 during pregnancy, the blood types of mother and baby are incompatible. The most common situation is that the mother's blood type is type O, while the baby's blood type is type A or type B. In fact, this kind of blood type incompatibility is not uncommon during pregnancy.

In addition, there is also RH type blood incompatibility between mother and baby, that is, the pregnant mother's blood type is negative, while the baby's blood type is positive. The mother may produce antibodies due to RH sensitization, and these antibodies enter the fetus's blood through the placenta and cause hemolysis. This is because the blood types of the pregnant mother and the fetus are incompatible, and the resulting hemolytic disease usually occurs during the fetal period and early neonatal period. So if you are a pregnant 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 suffer from hemolytic disease?

The answer is not necessarily. If the expectant mother has type O blood, the expectant father has type A, type B or type AB, and the fetus is type A or type B, the blood types of mother and child are incompatible.

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

In short, if the pregnant woman has type O blood, the fetus will not necessarily suffer from hemolysis. It depends on the blood type of the prospective father. In short, women with type O blood must pay attention to hemolysis before becoming pregnant. Get a check-up before getting pregnant and get pregnant scientifically under the guidance of a doctor. This is the only way to ensure the health of the fetus. Usually hemolysis can be prevented before pregnancy.
