Mom's first is positive. What blood type will the child have? What to do if you have an Rh conflict pregnancy

Rh factor (Rh factor) is a blood protein found on the surface of red blood cells. If this protein is present, then this means that the person has a positive Rh factor, but if it is not, then it is negative. Rh factor is determined by antigen. There are five main antigens, but the D antigen indicates Rh. 85% of the world's population have positive Rh factors. How to determine your Rh factor? It is enough just to donate blood from a vein once. This indicator does not change throughout life. In the embryo, Rh-affiliation is formed already in the first trimester of pregnancy. Determining this indicator is very important for a future mother, since in the case of an Rh-negative mother and a Rh-positive child, various pregnancy complications are possible. In this case, it will be especially important to follow the doctor's instructions, to avoid infectious and colds, as well as stress. Also on different sites there are so-called calculators that determine the Rh factor of the unborn child.

It must be remembered that blood is taken on an empty stomach. An express test for Rh affiliation can be taken at any independent laboratory where blood is taken (for example, Invitro). The price depends on the price list of the clinic itself. You can find out about the cost of the analysis immediately before delivery. You can also donate blood and find out your Rhesus for free if you become a donor. To do this, you need to fill out a form to register yourself as a blood donor in the appropriate institution.

Also, the Rh factor plays a big role in blood transfusion. Two people are involved in a transfusion: the recipient (the one who receives blood) and the donor (the one who donates blood). If the blood is incompatible, the recipient may experience complications after the transfusion.

The most common myth among couples is that the blood type (like the Rh factor) is inherited from a man. In fact, the inheritance of the Rh factor by a child is a rather complex and unpredictable process, and it cannot change during life. But it is worth remembering that in rare cases (about 1% of Europeans) a special type of Rh factor is determined - weakly positive. In this case, Rh is determined either positive or negative. This is where questions arise on the forums “why did my Rh minus change to plus?”, And also legends appear that this indicator may change. The sensitivity of the test method plays an important role here.

No less popular request on the network is "blood type horoscope". For example, in Japan, decoding by blood type is given great attention. Believe it or not - you decide.

In the world there is such a thing as a medical tattoo, photos of which can be easily found on the net. What do such tattoos mean and what are they for? Its designation is quite pragmatic - in case of a serious injury, when an urgent blood transfusion or operation is required, and the victim is not able to give the doctor data on his blood type and Rh. Moreover, such tattoos (a simple application of the blood type and Rh factor) should be in places accessible to the doctor - shoulders, chest, arms.

Rh factor and pregnancy

Rh factor compatibility during pregnancy- one of the tests that are carried out in the antenatal clinic. When a woman becomes registered with a gynecologist, she will need to donate blood to determine the group and Rh factor. It can significantly affect the course of the next nine months. If the baby inherits a positive father's Rh, and the mother's is negative, then the protein in the child's blood is unfamiliar to the mother's body. The mother's body "considers" the baby's blood as a foreign substance and begins to produce antibodies, attacking the baby's blood cells. With a conflict of Rh during pregnancy, the fetus may experience anemia, jaundice, reticulocytosis, erythroblastosis, fetal hydrops and edematous syndrome of newborns (in the last two cases, the probability of death of the child is high).

Blood type and Rh factor: compatibility

The cause of incompatibility can be not only the Rh blood, but also the group.

What are the blood types? They are distinguished by the presence of specific proteins.

Four groups:

• the first (most common) - O - there are no specific proteins in it;
• the second - A - contains protein A;
• the third - B - contains protein B;
• the fourth (the rarest of all) - AB - contains both type A protein and type B protein.

First

• on the protein of the second group (A);
• on the protein of the third group (B);

Second(Rh negative) in a mother can provoke a conflict:

• on the protein of the third group (B);
• on the protein of the fourth group (B);
• for the Rh protein (positive).

Third(Rh factor negative) in a mother can provoke a conflict:

• on the protein of the second group (A);
• on the protein of the fourth group (A);
• for the Rh protein (positive).

Fourth does not conflict with any other group.
The only case when an immune reaction is possible: if the mother has the fourth group and is Rh negative, and the father is positive.

Table 1. Statistics

Blood type and Rh - pregnancy without complications

The conflict does not arise if the spouses have Rh compatibility. In this case, the child has Rh compatibility with the mother's body: during pregnancy, the mother's body does not perceive the fetus as a foreign body.

Rh positive during pregnancy

If you are Rh positive, then a negative Rh husband will not affect the course of pregnancy. In the case when the child inherits the Rh factor is negative, there is no protein “unfamiliar” to the mother’s immune system in his blood, and a conflict will not arise.

• Rh-positive mother + Rh-positive father = Rh-positive fetus
  The child has inherited the positive Rh factor of the parents, and the pregnancy will pass without complications.
• Rh positive mother + Rh positive father = Rh negative fetus
  Even if the parent's Rh factor is positive, the baby can get negative. In this case, you can still talk about the compatibility of Rh factors during pregnancy: the mother's body is "familiar" with all the proteins in the child's blood.
• Rh-positive mother + Rh-negative father = Rh-positive fetus
  It is positive for the mother and the fetus, during pregnancy there is no conflict.
• Rh positive mother + Rh negative father = Rh negative fetus
  Although the mother and fetus have a different blood Rh factor (the mother and child have positive and negative, respectively), there is no conflict.

As already mentioned, blood Rh is a protein. And since this protein is already present in the mother's body, the blood of the fetus does not contain components that are unfamiliar to the mother's immune system.

Rh factor negative during pregnancy

Negative Rh during pregnancy is not always a sentence for the baby. The main thing is that it should be the same for both the baby and the mother.

• Rh negative mother + Rh negative father = Rh negative fetus
  The baby inherited the Rh factor of the parents. And since both the mother and the fetus have no protein (rhesus) in the blood and their blood is similar, then there is no conflict.
• Rh negative mother + Rh positive father = Rh negative fetus
  This is one of the cases when the Rh factor is very important: the compatibility of the blood of the mother and the fetus affects the next nine months of intrauterine life. Although the woman is Rh negative during pregnancy, it is good that the fetus is also Rh negative. There is no Rh in the mother's blood, nor in the blood of the fetus.

When does an Rh-conflict pregnancy occur?

Rh negative mother + Rh positive father = Rh positive fetus
Please note: whatever the mother's group, a negative Rh during pregnancy becomes a cause of conflict. In this case, the fetus inherits it from the father and brings the "new protein" into the body of the Rh-negative mother. Her blood "does not recognize" this substance: there is no such protein in the body. Accordingly, the body begins to defend itself and produce antibodies. They cross the placenta into the baby's blood and attack his red blood cells. The fetus tries to defend itself: the spleen and liver begin to work hard, while they increase significantly in size. If a child has few red blood cells, he develops anemia, or anemia.

What causes Rh conflict during pregnancy?

Rh-negative women should monitor their body very carefully and listen to its signals.
This attitude will help prevent:

• dropsy (fetal edema);
• anemia
• miscarriage;
• violations of the brain, speech or hearing of the child.

To protect the baby from these consequences, women with a negative Rh during pregnancy should take all the tests that the doctor prescribes on time.

What to do if you have an Rh-conflict pregnancy?

If your chosen one and you have Rh factors positive and negative, respectively, this must be taken into account when planning a pregnancy. Often, the Rh conflict does not appear during the first pregnancy, although the parents have a different Rh factor. Whatever the blood type of the future mother (Rhesus negative) during pregnancy, during the second birth, the likelihood of a conflict is very high, since her blood most likely already has antibodies.

Rh negative during pregnancy

There is a vaccine - anti-Rhesus immunoglobulin, which prevents Rh conflict during pregnancy. It binds the antibodies that the mother's body produces and brings them out. Vaccination can be done during pregnancy.

If you have a negative Rh, and your husband is positive, this is not a reason to refuse motherhood. Within 40 weeks, you will have to repeatedly donate blood from a vein:

• up to 32 weeks - once a month;
• from the 32nd to the 35th week - 2 times a month;
• from the 35th to the 40th week - once a week.

If Rh antibodies appear in your blood, the doctor can detect the onset of the Rh conflict in time. In a conflict pregnancy, immediately after childbirth, a newborn is given a blood transfusion: the group, Rh factor should be the same as that of the mother. This is especially important in the first 36 hours of a baby's life - mother's antibodies that have entered the child's body are neutralized by "meeting" familiar blood.

When can immunoglobulin prophylaxis be carried out?

To prevent conflict in subsequent pregnancies, Rh-negative women should be prophylactic. This is done after:

• childbirth (within three days);
• abortion;
• analysis of amniotic fluid;
• spontaneous miscarriage;
• ectopic pregnancy;
• detachment of the placenta;
• transfusions.

Remember: if your group and Rhesus are different with your baby, this is not an indicator that there will definitely be problems. Group and Rhesus are just the presence or absence of specific proteins in the blood. The reaction of the body and the development of pathologies in our time can be successfully controlled with the help of drugs. Your attention to your body, as well as an experienced doctor, will help you bear a healthy baby.

How do the chances of conception depend on the blood type?

Quite a lot is already known about the influence of blood groups, for example, on the likelihood of developing Alzheimer's disease, oncological diseases, blood clots, etc. However, virtually nothing was known about the effect on fertility. And finally, thanks to the efforts of Turkish doctors, a study appeared in this area.

A study published last week says that men with type 0 are four times less likely to develop impotence compared to guys with other blood types. Specialists from Ordu University in Turkey noted that blood type is as important a risk factor as smoking, being overweight, and high blood pressure. The reason is not clear, but scientists have said that in people with blood type A, the penis has a large number of veins, the lining of which can be damaged, which leads to erectile dysfunction.

Blood type also affects female fertility. Girls with the second group are more likely to bear a healthy child for a long time than with the first. Studies have shown that women with the first group quickly deplete their egg reserves early in life. But at the same time, women with type 0 have a lower risk of developing preeclampsia - high blood pressure during pregnancy, which can be dangerous for mother and child.

Naturally, representatives of the rest of humanity should not panic either (of which, by the way, there are a little more than half, because the people of the 1st group account for a little more than 40%) - a higher probability does not mean a 100% chance. As well as representatives of the "happy" group, you should not relax ahead of time - reduced risk does not mean zero at all.

For a long time, scientists have proven the existence of four groups. Accordingly, each of the groups is formed even at the birth of a child, or rather, even in the womb after conception. As people say - it is inherited. Thus, we receive a certain type of plasma from our parents and live with it all our lives.

It is worth noting that neither blood groups nor the Rh factor change during life. This is a proven fact that can only be refuted by a pregnant woman. The fact is that there are rare cases when a woman's Rh factor really changes during pregnancy - at the beginning of the term and at the end already before childbirth. Back in the middle of the 19th century, an American scientist reached the conclusion that incompatibility exists in the types of plasma. To prove this, he may have come in handy with a calculator, but to date, in this case, no one uses it.

Incompatibility is formed when different types are mixed and manifests itself in the form of aggregation of red blood cells. This phenomenon is dangerous by the formation of platelets and the development of thrombocytosis. Then it was necessary to separate the groups to determine their type, which led to the emergence of the AB0 system. This system is still used by modern doctors to determine blood groups without a calculator. This system turned all previous ideas about blood upside down and now only geneticists are engaged in this. Then they discovered the laws of inheritance of blood groups of a newborn directly from their parents.

Scientists have also proven that the child's blood type directly depends on the mixing of the parents' plasma. She gives her results or simply wins the one that is stronger. The most important thing is that there is no incompatibility, because otherwise pregnancy simply does not occur or threatens the child inside the womb. In such situations, special vaccines are made at the 28th week of pregnancy or during its planning period. Then the development of the child will be protected and the formation of his sex.

Type of blood according to the AB0 system

There were quite a few scientists who worked on the issue of inheritance of blood groups and sex. One of them was Mendeleev, who determined that children with the absence of A and B antigens would be born to parents with. The same situation is observed in parents with the 1st and 2nd blood groups. Quite often, the 1st and 3rd blood groups fall under such inheritance.

If the parents have the 4th blood group, then by heredity the child can get any, except for the first. The most unpredictable is the compatibility of parent groups 2nd and 3rd. In this case, inheritance can be in very different ways, while there is the same probability. There is also a rather rare situation when the rarest heredity occurs - both parents have antibodies of type A and B, but at the same time they do not appear. Thus, not only an unpredictable blood type is transmitted to the child, but also gender, and it is extremely difficult to predict its appearance, especially since the calculator will not help here either.

Probability of Inheritance

Since there are many different situations in the world, we will give the specific blood types of a person and the possible type of his child using a table. This does not require a calculator and additional knowledge. You just need to know your blood type and Rh factor. Such an analysis can be done in any specialized laboratory, which is prepared within 2 days.

Rh factor of blood

To date, not only the heredity of the blood group is known, but also its Rh factor and the gender of the person. This definition was also proven a long time ago, so many people today are worried about this: they want the child to get good blood.

Quite often there are cases when a spouse with a positive Rh, a child is born with a negative one. Then the question arises, on what it depends, or even distrust of each other in fidelity. But it is worth noting that with all the oddities of nature, this can also happen. There is an explanation for this, and to calculate this, you don’t even need a calculator. After all, the Rh factor, like the blood type, also has its own inheritance exceptions. Since Rh is a protein located on the surface of red blood cells, it has the ability not only to be present, but also absent. In its absence, they speak of a negative Rh factor.

Thus, it is also possible to present in the form of a table the possible options for the birth of a child with a certain Rhesus of a person in order to understand what it depends on. You don't need a calculator here, just knowing your Rh factor.

In addition to all this, it is worth considering that exceptions are quite common, which is explained by genetic science. Since the appearance of a person at birth is unpredictable, so are his structural features. Such a definition was proved already quite a few years ago, when the evolution of man was still progressing. In addition to all this, many still have a question about how the blood type and gender are inherited, because everything is so confusing and interesting that for an ordinary person it is not immediately clear.

Pregnancy planning includes measures to optimize conditions for conception and the birth of healthy offspring.

It is better for future parents to examine the body, give up bad habits, lead a correct lifestyle, and prepare yourself emotionally.

The most important nuance for conceiving a child in marriage will be checking the compatibility of parents by blood group and Rh factor according to the tables.

Story

Human blood is characterized by one of four groups, which differ in a set of specific proteins inside red blood cells.

Proteins (another name for antigens or agglutinogens) are denoted by the letters A and B. The erythrocytes of the first blood group do not contain antigens, the bodies of the second include only protein A, the third - B, the fourth - both proteins.

The age of the first antigenic phenotype is estimated at 60-40 thousand years.

It is common in areas of South and Central America, due to minimal migration and the absence of mixed marriages between local residents and representatives of other nations.

The second appeared much later in Asia, approximately 25-15 thousand years ago, a large proportion of carriers live in Europe and Japan. The number of people of groups I and II prevails and makes up 80% of the population.

The emergence of the third group is regarded by some researchers as the result of evolution that has changed the human immune system, others as the result of a mutation.

The emergence of the fourth group is a mystery to scientists. According to the investigations of the substance on the Shroud of Turin, in which the body of Jesus Christ was wrapped, he was the owner of this youngest group.

A child inherits a set of proteins from parents, based on the laws of genetics.

To determine the possible combination of antigens of the future baby, we find probable inheritance options at the intersection of the columns of the mother and father groups.

Inheritance during pregnancy

Table of inheritance of a blood group in a child.

Mom and dad with the second and third groups give birth to children of any combination of agglutinogens with the same probability.

In a couple with the first group, children are born whose red blood cells do not have proteins. The carrier of the fourth group will not give birth to the offspring of the first.

Genetics, like other sciences, is not without exceptions. In a small percentage of people, red blood cells include the A and B antigens that do not manifest themselves.

As a result, the infant inherits a set of agglutinogens that is different from what is possible. The paradox is called "bombay phenomenon" and is determined in one in 10 million people.

The circulatory system of the child is formed in the womb. Antigens appear in cells in the early stages of pregnancy (2-3 months).

When a baby inherits from his father a protein that is absent in the mother's blood, there are cases of a woman forming antibodies to a protein that is foreign to her.

This process is called blood type conflict or immunological conflict, and their compatibility is in question.

Incompatibility develops in the following cases:

• in a woman I group, in a man II, III, IV;
• in a woman II, in a man III, IV;
• in a woman III, in a man II or IV.

The alignment is especially dangerous when a woman of the first group bears a baby with II or III. This situation causes complications.

But more often the incompatibility proceeds easily. and does not require intensive care. Incompatibility during re-conception does not entail more unpleasant consequences.

Compatibility table for conception by blood type of husband and wife.

Sometimes the female immune system begins to produce anti-sperm antibodies that kill sperm. Then a healthy couple faces problems conceiving.

Therefore, proper pregnancy planning involves testing for antisperm antibodies.

Rh father and mother

In addition to the group, there is another antigen in the red blood cells - the Rh factor.

Most people on the planet are carriers of the Rh factor (Rh) They are called Rh-positive. Only 15 percent do not contain Rh in red cells, they are Rh-negative.

The inheritance of the antigenic phenotype and the Rh factor occur independently of each other. It is possible to say exactly which Rh factor a child will receive only when both parents have Rh negative.

In other situations, it is impossible to predict Rhesus, it can be anything.

Table for determining the rhesus of a child.

Some cases are characterized by immunological incompatibility for the Rh factor between the mother and the fetus.

Conflict manifests itself in a small percentage of women with a negative Rh, if the baby has inherited the father's positive Rh.

The mother's body produces antibodies that attack the baby's red blood cells through the placenta.

The placental barrier provides protection only in the ideal course of pregnancy, which is very rare. Attacks on a still unformed being destroy the liver, heart, kidneys.

Pregnancy complicated by Rhesus conflict often ends in miscarriage. When the baby manages to survive, dropsy, jaundice, anemia, and mental health problems are likely.

How to behave in case of Rhesus conflict

The expectant mother must know the blood type and Rh.

When planning a conception, it is worth taking tests(to determine the blood type and Rh factor), because the compatibility of spouses is important for the birth of healthy children, but not required.

Note that it is possible to bear and give birth to a healthy, strong child even with an immune conflict. The girl needs to be under the supervision of a doctor.

If antibodies are detected, treatment is prescribed. During the bearing of the firstborn, such a conflict appears less frequently, which is due to a number of biological reasons.

Risk factors for Rh - negative women are previous miscarriages, abortions,.

Antibodies can accumulate this means that the destruction of red blood cells during subsequent pregnancies will begin earlier, therefore, will cause more severe consequences.

The most serious complication is hemolytic disease of the newborn.

It is distributed in three forms:

• icteric - the skin turns yellow;
• anemic - jaundice, no edema;
• edematous - general edema, jaundice.

Diagnosis of incompatibility between mother and fetus begins with the determination of the Rh of the fetus.

With Rh-positive blood in the father and Rh-negative in the mother, pregnant women have their blood tested for antibodies at least once a month.

Bearing passes without discomfort, only slight weakness is possible.

Symptoms of incompatibility are detected only by ultrasound examination.

When there are more antibodies, and ultrasound shows abnormalities in the development of the fetus, intrauterine blood transfusions are done.

In the event of a threat to the life of the pregnant woman and the fetus, a decision is made on artificial childbirth.

The birth of a new life is a great happiness, which is sometimes overshadowed by a doctor's diagnosis after potential parents have been tested.

Pregnancy planning is the most important stage, but not a panacea for unpleasant surprises.

In this video, there is some more information about why it is so important for parents to take tests to determine the blood type and Rh factor when registering during pregnancy:

Even if you got pregnant out of the plan, don't worry. Love conquers everything, and a timely visit to a doctor and an examination will increase the chance of a favorable development of the child.

The membrane of red blood cells contains a different amount of proteins, as well as carbohydrates, which are referred to as antigens. It is from their presence that the characteristics of the blood will depend. The most numerous is blood type 1 with a positive Rh factor.

Attention! The Rh factor is an indicator of the antigen that is contained on the surface of red blood cells.

Initially, the 1st positive group was designated as the letter C, then it was decided to prescribe 0, that is, thus, it was indicated that there were no antigens in the blood. On the contrary, the presence of the H antigen can be found on the surfaces of erythrocytes, as well as in other tissues of the body. A positive Rh is assigned to this blood group due to the confirmation of the presence of antigen D in the owners.

It should be noted that the blood retains its original characteristics (group and Rhesus) throughout life. The 1st positive group can be inherited by the child either from one or both parents. Only if the parents do not have the 4th blood group. It should be noted that the first positive can be used as a universal donor blood for the transfusion procedure. Group incompatibility will be absent if the Rh is “+”. If a person is injected with blood with a negative Rh, then as a result, red cells, that is, erythrocytes, will stick together, with a subsequent deterioration in the person's condition.

How can the Rh factor affect?

One of the most important characteristics of blood is the Rh factor. As already mentioned, this is an indicator of the presence of an antigen on the surface of red blood cells. Simply put, this is an indicator of protein on the surface of red blood cells. Most people are characterized by the presence of antigens and, accordingly, have a positive Rh factor, the rest of the people are distinguished by their absence, therefore they have a negative Rh factor.

The Rh factor is very important in two cases:

1. During the period of bearing a child, it can threaten life from incompatible rhesus.
2. If surgery is being performed, which may involve a blood transfusion.

All other moments associated with Rhesus a priori do not affect the state of the body, therefore, they do not matter.

Pregnancy and blood compatibility

It is very important to plan pregnancy, because blood compatibility during this period occupies a special place in the birth of a healthy baby. When both parents have a negative or positive Rh, the child will accept the identical one as his parents, therefore, there will be no problems. The situation is similar with the acquisition of a blood group from parents. As studies have shown, babies often acquire the maternal blood type. Based on this, if the mother is carrier I positive, then there is a 90% chance that the baby will also be a carrier of this blood type, regardless of what blood type the father has.

Can there be an Rhesus conflict?

During pregnancy, the occurrence of such a problem as the Rhesus conflict is not excluded. It does not mean a combination of parents' rhesus: for example, the mother's is positive, and the father's is negative. The child in this case can acquire both negative and positive Rh. If the child takes maternal blood, then the pregnancy promises to be without problems.

Attention! A complication of pregnancy occurs when the child has a positive, and the mother has a negative Rh factor. Then there is a conflict between the blood of the fetus and the mother, which can lead to various serious complications during pregnancy.

Rhesus incompatibility has dangerous consequences. This is explained by the fact that antibodies produced by the mother's body can destroy the fetus. In half of the cases, the baby acquires a positive Rh, but if the mother is negative, then there is a risk of miscarriage or intrauterine death of the fetus.

How compatible are blood types?

Until recently, experts believed that plasma transfusion occurs without consequences in any quantities. The compatibility of the first positive with other groups was excellent. However, after a series of studies, it turned out that plasma contains agglutinins, and with frequent transfusions, the likelihood of a negative impact on human health increases. Based on this, it was decided to dilute the plasma of group I with the plasma of the recipient, and only after that proceed with the transfusion procedure in order to avoid possible complications.

Possible diseases

The owners of the first positive blood group are the least affected by serious diseases, so they live longer than the rest. However, they may be predisposed to stomach ulcers due to their high acidity. There is a high probability of an inflammatory process of the gallbladder and liver. Women may be at risk for skin tumors. But, despite the above ailments, the carriers of the first group are very resistant to nervousness, therefore they suffer the least from mental disorders and keep the youthfulness of the brain much longer.

Reference! Among carriersI blood group with a positive Rh factor is extremely rare for people suffering from schizophrenia.

Based on medical research, it has been found that people with the first blood group suffer from typical diseases:

1. Pathological lesions of the joints. Arthrosis and arthritis.
2. Location to permanent seasonal SARS.
3. Respiratory ailments.
4. Thyroid dysfunction.
5. Hypertonic disease.
6. Ulcerative lesions of the gastrointestinal tract.
7. Hemophilia among men.

Information about diseases depending on the blood type is contained in the video.

Video - Blood type and diseases

1. Poor blood clotting - such a statement is presented by hematologists. Therefore, it is very important to be careful when taking drugs that contain aspirin, which helps thin the blood.
2. There may be problems with the intestinal microflora, therefore, as a preventive measure, it is best to take probiotics.
3. Herbal decoctions (mint and rosehip) have a positive effect on the body. But, aloe and burdock root are recommended not to be used.

Proper nutrition

The health of each person is primarily affected by the diet. After all, the food of the daily diet should contain a set of products that positively affect the metabolism and the digestive system as a whole.

It was found that carriers of positive I tend to be overweight. An increase in extra pounds occurs due to a violation of proper healthy nutrition. From time immemorial, people with I positive have been hunters, so their diet should be mostly natural proteins. Such a statement was recognized even by official medicine. Therefore, it was installed list of necessary products for people withI blood group.

It is necessary to adhere to the peculiarities of dietary nutrition, since people with the first blood group are prone to diabetes.

Note! In general, for normal health, owners of all blood types are recommended to adhere to proper nutrition and lead a healthy lifestyle (with mandatory sports), but for people with a blood groupІ positive Rh factor, follows, builds his diet on foods high in protein.

It is known that foods rich in protein can, in small quantities, quickly relieve hunger and fully saturate the body. In addition, they support the normal metabolic process. Basically, protein-containing foods are all types of meat, especially dark. Particular attention should be paid to the liver, as an offal for cooking, which contains a sufficient amount of protein.

To avoid problems with the performance of the thyroid gland, you should regularly eat seafood that contains the required amount of iodine.

Attention! It must be recalled that it is the thyroid gland that is most often vulnerable in people with a blood typeІ positive Rh.

When planning a diet, it is necessary to take into account the blood type, therefore, at the first positive, it is recommended to use goji berries, more details can be found here.

Can blood affect a person's character?

According to statistical data, it was found that the owners of the first positive have a persistent character, are confident in themselves, are able to set goals and go towards them without going astray. A general characteristic shows that those with blood type I have strong willpower, so there are a lot of leaders among them.

Scientists have added increased emotionality, excessive jealousy and an increased level of self-preservation to the psychological portrait of such people. Self-confidence, backed up by leadership qualities, helps to calculate actions and steps in advance, determining in parallel one's own benefit.

Women with blood group I constantly analyze their activities and categorically do not perceive criticism in their direction. Most often they occupy high positions. A professional psychologist will tell you about how a blood type affects a person’s character and determines fate in a video. study on our website.

Video - How blood type affects our destiny and character

When deciding to conceive a baby, many young couples try to take into account all possible nuances. The key task is to create conditions for the child to be born healthy. To do this, before conception, it is worth going through all possible examinations, finding out the blood group of future parents. Let's see if the Rh factor and the blood type of a couple can be incompatible, and how this fact affects the conception and gender of the child.

When lovers plan to have a baby, they must carefully think through everything, prepare and be sure to pass an analysis for blood type compatibility.

What effect does blood type compatibility have on conception?

Each blood type has an international designation. The first is 0, the second is A, the third is B, the fourth is AB. This classification system is called AB0 and indicates the presence of specific enzymes in the blood. They are not only in group 0 (first).

In this case, the child can inherit the blood type of the mother, father, or have their own. You can calculate probabilistic indicators using special tables. For example, a woman and a man have the first group - the child will also receive the first. If mom has the first, and dad has the second, the baby can have both the first and the second.

What blood groups are considered incompatible? None of the combinations prevents conception and does not affect the gender of the crumbs. However, a conflict in the AB0 system sometimes occurs, but it manifests itself only with a small jaundice of the newborn. Also, pregnant women note manifestations of toxicosis - morning sickness and weakness.

In addition, according to some estimates, there is an influence of the blood type of parents on the growth and development of the baby. For example, there is an observation that health is stronger in those children whose mom and dad have different blood types. At the same time, it is desirable that a woman has a lower figure than a man.

Rh incompatibility

In addition to the blood type, the Rh factor matters. This refers to the presence of a special protein (D) on the surface of red blood cells. Those people who have this protein have a positive Rh, for the rest, this indicator is considered negative.

The Rh factor of the future baby can be predicted only in one case - if it is negative for mom and dad, it will be the same for the child. In other combinations, this protein in a baby may be determined, or may be absent.

Rh incompatibility of mother and baby occurs when a woman has a negative Rh, and a child has a positive one. In this case, the likelihood that the mother's immunity will perceive the Rh-positive baby as a foreign organism is high.

However, even then the pregnancy can pass without complications. Much depends on whether the mother's body was previously familiar with these antigens - proteins that are determined on the surface of the red blood cells of Rh-positive people. This "acquaintance" is called sensitization, and it can occur during a previous pregnancy, abortion, blood transfusion, etc.

If the woman's immunity has already developed in relation to this specific protein (antigen D), it can attack the baby when his blood enters through the placenta. This can happen already in the last months of pregnancy, when the permeability of the placenta increases significantly. Sometimes "acquaintance" occurs at the time of childbirth, which also requires the attention of a specialist.

The consequences of an immunological conflict are hemolytic disease of the newborn (we recommend reading:). This condition is accompanied by a massive breakdown of red blood cells and the accumulation of bilirubin in the tissues and organs of the baby. This component of bile can penetrate the heart and brain, causing irreparable damage. The course of the disease can be quite severe and lead to death.

What to do if there is an Rhesus conflict?

Despite the likelihood of a Rh conflict, a mother with a lack of D antigen has the opportunity to avoid trouble and risk to the health of the baby. There are various ways to prevent pregnancy complications. It is important to register with the LCD in a timely manner and fulfill the appointments of an obstetrician-gynecologist.

To begin with, experts determine how high the risk is that the mother's immune cells will harm the child. To do this, the entire period of pregnancy, the expectant mother regularly donates blood for analysis, which determines the presence of antibodies. Title 1:4 already indicates an immunological conflict. If the result shows 1:64, the doctor will suggest an early delivery in order to avoid the baby's illness.

In the presence of a Rh conflict, a woman is immunized at the 28th week of pregnancy

The next stage is the immunization of the mother at 28 weeks. A woman is shown an intramuscular injection of a special type of immunoglobulin (anti-D gamma globulin). These antigens destroy the erythrocytes of the fetus, which have penetrated the placenta into the mother's body before the moment when her immunity has time to respond to them.

Immunization is required when antibodies are not detected in the patient's blood. Otherwise, its effectiveness will be zero.

Table for determining the blood type of the unborn child

We mentioned that there are ways to predict the likely blood type of an unborn child. Our table will help to guess which group the baby will have, but it will not give a 100% answer.

As can be seen from the table, in almost all cases (except one - when mom and dad have 1 group), 2 or more options are acceptable. The greatest number of variations in a child in whom both parents have group 3 - a baby can be born with both 1 and 2, 3 or 4. Only laboratory tests can give a guaranteed correct answer.

If the mother is Rh positive

Geneticists and obstetricians claim that a positive mother's Rh factor is guaranteed to avoid the development of hemolytic disease in a child.

Despite the fact that the blood of the baby and his mother may not match in Rhesus, you should not worry about the development of an immunological conflict.

Two scenarios are acceptable - the child will be Rh positive or Rh negative:

• in the first case, almost complete compatibility is determined - the mother's immunity will perceive a specific protein in the blood of the fetus as already familiar;
• in the second, the blood of the crumbs will generally be without an antigen that can cause an immunological response.

If the mother is Rh negative

If the expectant mother has a negative Rh factor, she will need to undergo an additional examination. It is believed that the Rh factor in the fetus is finally formed by the 3rd month. The problem arises only if the crumbs have a positive Rh, but it is almost impossible to know for sure. The penetration of particles of the baby's blood through the placenta can provoke an immunological conflict, and then the baby will be seriously affected.

Signs of hemolytic disease are diagnosed by ultrasound

The doctor in the antenatal clinic closely monitors the condition of such a patient and her child using various methods:

1. ultrasound. Ultrasound examination helps to see at an early stage signs of hemolytic disease of the newborn - an increase in his liver, thickening of the placenta, polyhydramnios.
2. Dopplerography. This type of examination is a type of ultrasound. It allows you to assess the blood flow in the cerebral artery, to see other pathologies.
3. Examination of pregnant women's blood for antibodies. An important indicator is not only their number, but also the dynamics. If the concentration of antibodies is rising, there is cause for alarm.
4. Sometimes a puncture of the amniotic fluid and a study of cord blood for bilirubin are performed (see also:). This is shown only in critical situations, since the procedure can cause premature birth of the baby.

Can the incompatibility be cured?

As we have already found out, the problem in the compatibility of the blood of the mother and the fetus can only be in the presence of a Rh conflict. Experts say that the Rh factor is lifelong and cannot change. However, there is a category of people with a “weakly positive” factor in whom the presence of the D antigen is not always easy to detect. It is these people who can find out that their Rh factor was determined incorrectly.

In this regard, it is impossible to achieve compatibility between the blood of the mother and the child. You can only carry out prophylaxis (introduction of antigen) and monitor the condition of the pregnant woman and the fetus. In critical cases, the following measures are possible:

• exchange transfusion of blood to a child in the womb;
• plasmapheresis - cleaning the blood of a pregnant woman from antibodies;
• stimulation of labor for a period of 36 weeks.

There are other ways to eliminate the consequences of incompatibility. For example, intravenous administration of glucose and a number of special solutions.

How to get around the problem?

According to experts, the risk of developing hemolytic disease of the newborn increases with subsequent pregnancies of an Rh-negative patient. During childbirth, particles of fetal blood can enter the mother's blood, which allows the woman's body to develop immunity against an unfamiliar blood protein.

To avoid this, it is advisable to plan pregnancy in advance. If the husband's Rh factor is determined to be weakly positive, IVF is recommended in special cases. From ready-made embryos grown in a test tube, Rh-negative is selected and placed in the woman's uterus.

A significant moment is the postpartum injection of immunoglobulin. In this case, the risk of complications in subsequent births is significantly reduced. Anti-D globulin should be administered within 72 hours after the baby is born.
