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.
| Blood type (1 parent) | Blood type (2nd parent) | Child's blood type, % probability | |||
| 25 | 50 | 75 | 100 | ||
| I(0) | I(A) | I | |||
| I(0) | II(A) | I, II | |||
| I(0) | III(V) | I, III | |||
| I(0) | IV(AB) | II, III | |||
| II(A) | II(A) | I | II | ||
| II(A) | III(V) | I, II, III, IV | |||
| II(A) | IV(AB) | III, IV | II | ||
| III(V) | III(V) | I | III | ||
| III(V) | IV(AB) | II, IV | III | ||
| IV(AB) | IV(AB) | II, III | IV | ||
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:
- ultrasound. Ultrasound helps to see early stage signs of hemolytic disease of the newborn - an increase in his liver, thickening of the placenta, polyhydramnios.
- 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.
- 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.
- Sometimes amniotic fluid puncture and examination cord blood for bilirubin (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.
The Rh factor of a person cannot be changed, so women with a negative Rh need to be observed by a doctor throughout their pregnancy. 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 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.
Since the discovery of the AB0 system, people have been trying to determine the nature of the blood type. This practice has reached a special scale in Japan. Here, for the first time, they started talking about the relationship between blood type and human character. A certain Masahito Nomi and other members of his family were studying this problem. As a result, he published materials in which he described character traits by blood types, gave a number of recommendations on the application of this knowledge in life, and also touched on the topic of compatibility.
It is said that the Japanese take blood type into account when hiring a person, forming a sports team, or choosing a life partner. Stories about celebrities necessarily include a mention of their blood type. In Japanese stores, entire shelves are devoted to literature on this topic. It is believed that the blood type affects not only the character of a person, but also the tendency to disease, as well as the ability to play a particular sport. Even the menu is recommended to be made taking into account this characteristic.
According to the most common classification, there are four blood groups. Thus, it is customary to distinguish four types, each of which is given detailed description. As you know, blood groups appeared in the course of evolution as a result of climate change, living conditions, the development of certain skills and eating habits. Perhaps it is with this that the formation of character traits and various personal qualities is associated.
I group
Carriers of this blood are called hunters.
Today they make up about half of all living on Earth - 40-50%. This is the oldest group, and it is believed that all ancient people from the time of hunting for mammoths possessed only this blood.
To survive in those conditions, it was necessary to have a strong character. And in our time, the carriers of the first group are endowed leadership qualities, ascribes to them purposefulness and self-confidence. It is generally accepted that these people are stress-resistant, hardy, determined, able to control themselves, have strong nerves, and recover quickly. They are energetic, ambitious, mobile, have a high capacity for work, always have a positive attitude and infect others with optimism.
"Hunters" are easily trained, like to learn new things, have a tendency to different types activities and are able to achieve success in any business. Monotony is alien to them, they are attracted by the unknown and new experiences, they prefer travel and extreme sports sports. People with the first group are sociable, easily make new acquaintances, and are doomed to be the soul of the company. They make good organizers, bankers, leaders. At the same time, they can be very tough, harsh, categorical, unbalanced, arrogant, jealous, they can hardly endure criticism in their address. They can take on several cases at once, but they do not always bring them to the end. It is believed that there are especially many people with the first group among centenarians.
II group
For the owner of this group, the definition of "farmer" or "owner" was chosen. About 30-40% of people are carriers of this blood. It was formed at a time when people began to engage in agriculture and began to lead a sedentary lifestyle. Now there are fewer dangers, eating habits have changed. The qualities necessary for a hunter receded into the background. People of this group are calm, responsible, hardworking, obligatory. They are slow, patient, cautious, prudent, accurate, tend to pay attention to detail. Great importance for a man acquires his house. There is a desire to expand their territory, provide comfortable living and maintain order.
People with Group II seek harmony in everything, are endowed with a sense of justice, interact well in a team, but never strive to take a leading position, rather, they like to take a subordinate position. They are supporters of a peaceful solution to all issues, they will never make scandals, they strive to reconcile others, they are always friendly, attentive and caring. At the same time, there are maximalists and conservatives. They tend to hide grievances and feelings, they are characterized by stubbornness and irritability. Nervous system they are weaker than the "hunters", they are less emotionally stable and may be prone to depression. More than anything, they value order, comfort and peace, both domestic and spiritual. They make good service workers, salespeople, teachers, doctors.
III group
People with the third group are approximately 10-20%. They are called wanderers or nomads. The group was formed in Asia at a time of climate change and the emergence of a nomadic lifestyle. In such conditions, people had to learn to quickly rebuild and adapt to the new. Carriers of this blood are emotional, prone to frequent mood changes, independent, not tied to home, and are not adherents of traditions. These are bright creative personalities capable of shocking. They are completely devoted to their work, have the ability to high concentration. They are creative, imaginative, unpredictable, wild, original, sensitive. They have flexibility, optimism, in essence, they are ascetics and individualists. They do not tolerate dependence on anyone and an unfair attitude towards themselves. They cannot be called sociable, it is not easy to make contact, they are laconic. They are aggressive, but usually take into account the opinions of others and know how to empathize and show sympathy. Outwardly, they are usually calm, behave with restraint, even if passions rage inside. Their credo is to live for themselves in complete independence. They can make good jewelers, investigators, lawyers.
IV group
This is the youngest and rarest blood type. Its owners on the planet are only 5%. I call them philosophers. It is believed that they are intelligent, tactful, balanced, honest, forgiving, cold-blooded. They do not pay attention to trifles, are sociable, get along with almost everyone, are prone to philosophy, diplomacy and rationalism. Excellent organizers, they know how to draw attention to themselves, they have a well-developed intuition. They are smart, extraordinary, are considered multifaceted and spiritualized personalities. They are prim and indecisive, they cannot make a decision for a long time. They are afraid to spoil relations with others, therefore they are often meek, soft and conflict-free. They may be haunted by internal conflicts that reduce self-esteem. People with IV blood group have a well-developed creative thinking Among them are many inventors and scientists. They make good librarians and archivists.
Health
Our blood type has a big impact on our body along with our diet and lifestyle. As you know, there are 4 types of blood groups: I (O), II (A), III (B), IV (AB).
A person's blood type is determined at birth and has unique characteristics.
All blood types have several characteristics that, interacting with each other, determine how external influences affect our body. Here are a few facts that would be interesting to know about the blood type.
1. Nutrition by blood type
Throughout the day in our body occur chemical reactions, and therefore blood type plays an important role in nutrition and weight loss.
People with different blood types should consume different types of food. For example, people with I (O) blood type, it is worth including protein-rich foods in the diet such as meat and fish. People from II (A) blood type should avoid meat because vegetarian food is more suitable for them.
To those who have III (B) blood type, you should avoid chicken meat and consume more red meat, and people with Group IV (AB) will benefit more from seafood and lean meats.
2. Blood type and disease
Because each type of blood different characteristics, each blood type is resistant to a certain type of disease, but more susceptible to other diseases.
I (O) blood type
Strengths: strong digestive tract, strong immune system, natural protection against infections, good metabolism and nutrient retention
Weak sides: blood clotting disorders, inflammatory diseases (arthritis), diseases thyroid gland, allergies, ulcers
II (A) blood group
Strengths: adapts well to dietary and external diversity, retains and metabolizes nutrients well
Weak sides Key words: heart disease, type 1 and type 2 diabetes, cancer, liver and gallbladder disease
III (B) blood type
Strengths: strong immune system, good adaptability to nutritional and external changes, balanced nervous system
Weak sides: type 1 diabetes, chronic fatigue, autoimmune diseases (Lou Gehrig's disease, lupus, multiple sclerosis)
IV (AB) blood type
Strengths: well adapted to modern conditions, stable immune system.
Weak sides Key words: heart disease, cancer
3. Blood type and character
As mentioned earlier, our blood type also affects personality.
I (O) blood type: outgoing, confident, creative and extroverted
II (A) blood type: serious, accurate, peaceful, reliable and artistic.
III (B) blood type: dedicated, independent and strong.
IV (AB) blood type: reliable, shy, responsible and caring.
4. Blood type and pregnancy
Blood type also affects pregnancy. For example, women with IV (AB) blood type produce less follicle-stimulating hormone, which helps women get pregnant more easily.
Hemolytic disease of the newborn occurs when the blood of the mother and fetus is incompatible with the Rh factor, sometimes with other antigens. If an Rh-negative woman has a fetus with Rh-positive blood, an Rh conflict occurs.
5. Blood type and exposure to stress
People with different blood types react differently to stress. Those who lose their temper easily are more likely to have I (O) blood types. They have more high level adrenaline, and they need more time to recover from a stressful situation.
At the same time, people with II (A) blood type have higher levels of cortisol, and they produce more of it in stressful situations.
6. Blood group antigens
Antigens are present not only in the blood, but also in the digestive tract, in the mouth and intestines, and even in the nostrils and lungs.
7. Blood type and weight loss
Some people have a tendency to store belly fat, while others may not be concerned about it due to their blood type. So, for example, people with I (O) blood type are more prone to fat in the abdomen than those with II (A) blood type, who rarely have this problem.
8. What blood type will the baby have?
Many people are aware that they need to know their blood type in case of emergency. However, most of us do not even realize that it plays a huge role in our lives. A person's blood type is reflected in his health in general and mood in particular. Unexpected facts about blood type will surely surprise you greatly.
Different nutritional needs
Each individual blood type has its own nutritional needs. For example, those in group 1 are prone to indigestion, so they should consume as much protein, fish, vegetables, meat and poultry as possible. Carriers of the 2 blood type have a very sensitive immune system, so they should include as many citrus fruits, garlic, spinach and cruciferous vegetables in their diet as possible. Group 3 people are advised to eat more honey, lean meats, eggs and vegetables, as they often suffer from stomach problems. Owners of the rarest - 4 blood groups need to add honey and apple cider vinegar to the menu. These foods stimulate the production of stomach acid, which the body does not produce enough.
stress level
People with blood groups 1 and 2 have elevated level stress due to increased cortisone production. At the same time, the owners of groups 3 and 4 get angry, upset and nervous much less often.
Blood type and cancer
According to scientists, a person's blood type determines the risk of developing cancer. For example, the chance of getting stomach cancer or ulcers is higher in people with group 1. At the same time, carriers of group 2 have serious problems with the level of "good" cholesterol "- it is too low.
Fat deposits in the abdomen
The biggest difficulty in trying to lose weight is experienced by people with 2 blood groups. At the same time, the most problematic place for them is the stomach. Also, carriers of group 2 are at a greater risk of developing diabetes than owners of other blood groups. Therefore, they should avoid shellfish, meat and dairy products. These foods cause acid reflux, bloating, and indigestion.
Blood type affects personality
According to studies, people with the same blood type have many common features and habits. For example, the owners of group 1 are very restless, but well-organized and practical natures. Carriers of the 2 blood group are compassionate and always put the needs of other people first, 3 are sociable and friendly, and 4 are strong-willed and rational.
Knowing your own blood type can save a life
For those who are not yet aware of this, it should be repeated. Knowing your own blood type can save a life in an accident. If doctors do not waste time finding out the group of the victim, his chances of recovery will greatly increase. It should also be remembered that someone else's blood type during transfusion can cause many life-threatening complications.
The Rh factor of the blood affects the child
In addition to the group number, each person also has a Rh factor. It is positive and negative. Nearly 85% of people worldwide are Rh positive.
If the parents of the unborn child have the same Rh factor, then there should not be any complications. But if the mother is Rh negative and the father is Rh positive (and vice versa), then this often causes a risk to the health of the child.
