In ancient times, people were more cautious when dealing with some of the more important things in life. They often find a "master" to do the math. Just like a big event like getting married, many people will ask the "master" to calculate an auspicious day for themselves, which means it will be a good sign. Under normal circumstances, master fortune tellers calculate according to the birth dates of two people, so that they can see whether the two people are compatible. If the master calculates that two people are not suitable for each other, he will say "their horoscopes are not compatible." We have all heard of "incompatible horoscopes", but have you ever heard of "incompatible blood types" between a couple?
The wife was worried that she and her husband had incompatible blood types and refused to give birth to the next generation
After Xiaomei and her husband got married, her mother-in-law has been urging the couple to have children as soon as possible, but Xiaomei has been slow to do so. Not pregnant. Later, her husband accidentally discovered that Xiaomei was secretly taking birth control pills, and he couldn't understand why Xiaomei didn't plan to have a child. Only then did Xiaomei tell her the reason. It turns out that Xiaomei’s blood type is type O, while her husband’s blood type is type B. Xiaomei heard from colleagues around her that if a person with type O blood and a person with non-O blood combine, the baby will be more likely to have the disease. He had hemolytic disease in newborns, so he didn’t dare to get pregnant.
What is hemolytic disease of the newborn?
We all know that a person’s blood type is inherited from both parents. When the couple’s blood types are different, the fetus will inevitably choose one. Blood type inheritance. If the blood type of the fetus and the mother are the same, then they will be fine; but if the blood type of the fetus and the father are the same, they will be inconsistent with the mother's blood type. At this time, the mother's body will produce antibodies against the fetus, which will destroy the fetus' red blood cells and cause hemolysis. Medically, this disease caused by a couple’s blood type incompatibility is called hemolytic disease of the newborn.
Neonatal hemolytic disease is very common now, and generally does not have any serious consequences. It is more common for newborns to develop jaundice within 24 hours after birth, but as the mother's antibodies in the body gradually decrease, So the symptoms will subside accordingly. No matter how severe it is, it can lead to neonatal anemia, liver edema, etc., and sometimes it can even be life-threatening.
Which blood types are incompatible between couples?
There are two types of hemolysis that generally occur between couples: ABO hemolysis and RH hemolysis.
ABO hemolysis is more common now, and its impact on the fetus is nothing more than neonatal jaundice, which can be easily cured by exposure to blue light the day after tomorrow. What is of greater clinical concern is RH hemolysis. Nowadays, most people have RH-positive blood, and negative blood is relatively rare. However, if one of the couple has RH-positive blood and the other has RH-negative blood, then mother-child RH blood type incompatibility will occur. Mother-to-baby RH blood type incompatibility is fine during the first pregnancy, but if there has been a previous pregnancy or miscarriage, the possibility of hemolysis in the fetus is very high, and the impact on the fetus is also relatively large, such as miscarriage, miscarriage, Developmental malformations, etc.
Can I not conceive a baby if my blood types are different?
In fact, in life, it is very common for couples to have incompatible blood types, but hemolysis in the fetus is rare. This is because although the mother's body releases antibodies, the antibody molecules are relatively large. The placenta is a barrier that protects the fetus, so almost only a small part of the antibodies enter the fetus. These small amounts of antibodies will also be slowly metabolized and exhausted within a period of time after the fetus is born, so the child will return to normal soon, and parents do not need to worry too much.
If couples know that their blood types are incompatible, they should not easily abort once they become pregnant, because the chance of hemolysis in the first child is very low. Otherwise, the more miscarriages a woman has, the greater the chance of maternal and fetal blood type incompatibility. And now during pregnancy, pregnant women will have ABO hemolysis tests. If you have had miscarriage, fetal arrest and other adverse maternal experiences in the past, you must have ABO hemolysis tests regularly. Do not take it lightly.
