If the husband and wife are "incompatible in blood type", what danger will it bring to the children?

In ancient times, people were cautious when dealing with some important things in life. They often look for "masters" to calculate. For a big event like marriage, many people will ask the "master" to work out an auspicious day for themselves, which means good luck. Generally speaking, the master's fortune-telling is based on the date of birth of two people, so that we can see whether two people are suitable or not. If the master figures out that two people are not suitable, he will say "eight characters are not suitable." We have all heard of "eight-character incompatibility", but have you ever heard of "blood type incompatibility" between husband and wife?

The wife is worried about her blood type incompatibility with her husband and refuses to give birth to the next generation.

After Xiaomei and her husband got married, her mother-in-law kept urging the couple to have children quickly, but Xiaomei was never pregnant. Later, her husband accidentally discovered that Xiaomei was secretly taking birth control pills. She didn't understand why Xiaomei didn't plan to have children. Xiaomei said the reason. It turns out that Xiaomei's blood type is O type, while her husband's blood type is B type. Xiaomei heard from colleagues around her that if a person with type O blood is combined with a person with non-type O blood, then the baby born is prone to neonatal hemolysis, so she is very afraid of pregnancy.

What is hemolysis of newborn?

As we all know, a person's blood type is inherited by his parents. When the husband and wife have different blood types, the fetus will inevitably choose a blood type to inherit. If the fetus and the mother have the same blood type, then nature is peaceful; But if the blood type of the fetus is the same as that of the father, it will be different from that of the mother. At this time, the mother will produce antibodies to the fetus, destroy the fetal red blood cells and cause hemolysis. Medically, this kind of disease caused by blood group incompatibility between husband and wife is called neonatal hemolysis.

Newborn hemolysis is very common now, and generally there will be no serious consequences. It is more common that jaundice occurs within 24 hours of birth, but with the gradual decrease of antibodies in the mother's body, the symptoms will also subside. If it is serious, it will lead to neonatal anemia and liver edema. Sometimes even life-threatening.

What blood types are incompatible between husband and wife?

There are two kinds of hemolysis between husband and wife: ABO hemolysis and RH hemolysis.

Like ABO hemolysis is more common now, the impact on the fetus is nothing more than neonatal jaundice, and it is easy to recover through blue light irradiation the day after tomorrow. RH hemolysis is more concerned in clinic. At present, most people are RH positive blood, and there are few negative blood. However, if one of the husband and wife is RH positive blood and the other is RH negative blood, there will be RH blood group incompatibility between mother and baby. When pregnant with the first child, there is no problem that the RH blood group of the mother and the baby is incompatible. However, if there is previous experience of pregnancy or abortion, the possibility of fetal hemolysis is very high, and the impact on the fetus is also relatively great, such as abortion and fetal malformation.

Can't you have a baby with a different blood type?

In fact, in life, blood group incompatibility between husband and wife is very common, but fetal hemolysis is rare. This is because although the mother will release antibodies, the antibody molecules are relatively large, and the placenta is the barrier to protect the fetus, so almost only a small part of antibodies enter the fetus. These small amounts of antibodies will also be slowly metabolized and exhausted within a period of time after the birth of the fetus, so the child will soon return to normal, and parents need not worry too much.

If both husband and wife know each other's blood types are incompatible, then once they are pregnant, don't miscarry easily, because the chance of hemolysis of the first child is very low. Otherwise, the more times a woman miscarries, the greater the chance of blood group incompatibility between mother and baby. And now there will be ABO hemolysis test for pregnant women during pregnancy. If you have had bad pregnancy experience such as miscarriage or abortion in the past, then you should do ABO hemolysis test regularly and don't take it lightly.
