Negative blood type during pregnancy
If the expectant mother has a negative blood type, pregnancy is fraught with complications. The mother’s antibodies will fight the baby’s red blood cells. Doctors call this phenomenon Rh-conflict. However, parental compatibility within the group is also important. If it is different for them, then in some cases pregnancy can proceed with complications.
Blood type and pregnancy: which group will get the child
First, all blood groups are present in the fetus. They are presented in different percentages. If the spouses have the same indicator, then the child will inherit their group.
Negative blood type during pregnancy can lead to conflict between mother and fetus
The exception is only 2% of newborns who have a group different from the parent.
The baby will be healthier and less susceptible to disease if the husband’s blood type is higher than that of his wife. For example, a woman has I, and a man has any other
With different indicators of parents, a child can have any group. Doctors give only a 25% guarantee that it will match the mother’s or father’s. Although, according to statistics, in most cases, the baby receives the mother’s group.
Incompatibility of parents by blood group
Blood type during pregnancy is important. The blood of different groups has biochemical characteristics that are determined by the structure of proteins. If the parents have different groups, then their incompatibility may arise. 25% of pregnant women face this problem.
Doctors consider the IV female blood group the most favorable, since it is combined with any male group. There are no complications even when the father has a blood group I. In other cases, the situation looks like this:
- Mom has the first group. Ideally, the future dad should have the same. The most risky blood group, the most likely immunological conflict with the IV group. But it is possible with both II and III.
- Second. Compatible with I and II. Problems can arise with III and IV.
- Third. It is good if the spouse has I or III group. But II and IV can cause conflict.
The sooner a woman registers, the more chances to prevent pathology. Compliance with all the doctor’s recommendations will lead to a favorable birth.
Why is a negative blood type dangerous during pregnancy?
Don’t forget about the Rh factor. This is the name of the surface protein found on erythrocytes. However, not everyone has it, 25% of people do not have it. It is believed that they have this indicator is negative.
A danger to the development and vital functions of the fetus can arise if the woman has negative blood, and the unborn child has positive
With the Rh-conflict, the body of the expectant mother begins to produce antibodies that perceive the child’s blood as foreign. Red blood cells are destroyed. This provokes the destruction of hemoglobin, resulting in the formation of a toxic substance – bilirubin.
The first pregnancy with a negative blood group is less dangerous, since the mother’s body has not yet developed antibodies. The second is causing great concern. The death of red blood cells can lead to hypoxia, hemolytic disease, which manifests itself in the form of jaundice in newborns, anemia in the first year of life. A high concentration of bilirubin causes encephalopathy. It is characterized by retarded mental development, impaired speech, and coordination of movements.
In such cases, a woman should donate venous blood for analysis. Until the 32nd week, this must be done every month, until the 35th week – twice a month, and then – weekly
Only then will the gynecologist be able to analyze the concentration of antibodies and notice the “blood feud” in the early stages.
The situation can be corrected with the help of special drugs, preventive vaccination. If the child was nevertheless born with an illness, then phototherapy is prescribed to him – a procedure that allows you to reduce the amount of bilirubins. In extreme cases, the baby is given a blood transfusion.
