1 negative blood type

Each person should know their blood type and rhesus affiliation. These are minimal biological personality traits and differences that can be identified already at the stage of outpatient examination.

The first negative blood group is found in 15% of people in Europe, in 7% of Africans, and is practically not common in India. The rarity of the group depends on the geographical features of the continent. In Europe, for example, the fourth negative is much more scarce.

How is 1 negative?

A child gets his genes from his parents. Blood type is provided by a combination of antigens. Based on the possible chromosomal compounds, it can be said with confidence that 1 negative according to the prediction of the group and rhesus is different.

The first group can form in the fetus:

  • with 100% probability if both parents have it;
  • with equal opportunity, if one of the parents has the first group, and the other has the second or third.

A child with this indicator will never be born if one of the parents has a fourth group. This simple test is used in genetic counseling and forensic medicine for controversial paternity.

Rhesus is an additional antigen of erythrocytes.

  • It definitely will not be in the blood of a newborn, if both parents do not have it.
  • If the mother or father has Rh antigen, then the probability of having a child with a negative Rh is 50%.


A person whose first negative, due to the lack of antigenic properties is considered the safest donor for blood transfusion. In the absence of one-group in life-threatening situations, it can be transfused to people with any other blood, regardless of the presence or absence of the Rh factor.

In a planned manner, such transfusions are prohibited.

According to some theories, the owners of this group are very strong-willed people who strive to be always leaders. They really reach the goal. Characteristic features are: increased emotionality, a developed sense of self-preservation. Such a person will not risk their health, he calculates the result of actions in advance.

Perhaps such a transfusion is shown in this case.


If a patient with the first group and negative rhesus needs a blood transfusion, then only a similar donor will be suitable for him. Therefore, doctors advise such people to know which of the relatives have the same blood as them.

Typical diseases of people in this group are:

You can also read:

  • stomach ulcer and duodenal ulcer;
  • increased risk of hypertension;
  • more often hemophilia is found in men;
  • susceptibility to respiratory tract infections (ARVI, influenza, tuberculosis, pneumonia);
  • there is a risk of weight gain;
  • allergic reactions are possible.

An overrun of volitional qualities can lead to narcissism, intolerance to any criticism and remarks, and jealousy. Reduced endurance and inability to adapt to changing living conditions is the cause of a short-term fall.

Problems during pregnancy

Pregnancy for a woman with a lack of Rh factor in the blood has the same effect regardless of blood type. Gynecologists send both spouses to the laboratory to determine rhesus.

The expected course of pregnancy may be complicated by Rh-conflict with the fetus, if the child receives the Rh-positive genes of the father. The first pregnancy is considered more favorable, because the mother’s immune system begins to reject the fetus only at the end of the term. A child is born with jaundice, a liver disorder, anemia. Such a baby is taken under control and receives timely treatment. With age, he becomes completely healthy.

With repeated pregnancy (even taking into account previous abortions), ready-made antibodies are present in the woman’s blood, and they begin to act on the fetus from the first weeks. It threatens miscarriage, violation of the formation of internal organs.

Modern medicine has learned to deal with this pathology by administering an anti-rhesus globulin, which has the ability to bind and neutralize the action of maternal antibodies. Rhesus-negative women should take care of the future of their children.

Dietary tips

In the last century, the theory of dependence of nutrition on blood type was very popular. Rh factor in it is completely ignored. It was believed that there are certain products that are most important for a person with each blood group. And also indicated unhealthy food, which slags the body, contributes to the occurrence of diseases.

Here is who ate only meat

The origin of all people with the first group is genetically related to the first human-like individuals that do not have antigens in their blood. They hunted and ate only meat food. Due to the dramatic changes in the ecology of the current hunters it is impossible to eat the same meat, and other useful products will be needed.

Diet offered to observe all my life. Although the theory has long been refuted by lengthy research, it still has followers. Therefore, we give all that relates to the first blood group.

People with this symptom are considered obese. Rational nutrition requires the restriction of sweets, flour products.

  • Showing dishes from lean beef or lamb, fish, seafood.
  • Cook porridge should only be whole grains (buckwheat is most useful).
  • It should be preferred dishes of pumpkin, broccoli, spinach, seaweed with onions, parsley.
  • You can drink green tea, herbal teas, broth hips.

1 negative blood type The usual recommendations will have to be critical.

What not

The combination of milk and meat dishes in a one-day ration is not recommended, especially pork.

  • Prohibited sausage, smoked, fatty meat.
  • Dairy products and eggs.
  • It is proposed to abandon the acidic fruits and berries, olives, citrus, orange, tangerines, strawberries.
  • Oatmeal, semolina is limited.
  • Contraindicated is considered to be butter, hard cheeses, ice cream, ketchup, mayonnaise.
  • Potatoes, beans, cabbage.
  • Black tea, coffee, orange juice, kefir and milk.

The theoretical basis of nutrition for the blood group provides for a gradual transition to a strict diet, allow temporary relief. Some consider this approach the only rational for losing weight or maintaining weight and health.

Blood type and disease!

Modern medicine does not approve of nutritional excesses, but also against veganism. Food should have all the necessary components, otherwise it will take a long time to restore the imbalance with medicines.

Women in early pregnancy should be tested for the determination of blood type and Rh factor. Why these indicators are important for the future mother and for the development of the fetus – says obstetrician-gynecologist Gayane Hakobyan.

Rhesus factor in parents is one of the most important factors determining the course of pregnancy. Today, with timely diagnosis, the Rh problem can be overcome by administering an antiresus immunoglobulin over a period of 26-27 weeks. Moreover, genetics in this direction has made great strides forward and is able to predict the possible difficulties of carrying a child and his own health at the planning stage of pregnancy. In order to describe all possible scenarios, geneticists need to know the blood group and rhesus of both prospective parents, as well as the number of pregnancies in a woman. If any pregnancy is interrupted, this information is also very important. For example, the pregnancy of a woman whose blood type 1 is negative, and her husband is positive, can lead to an immune conflict in the fetus. Since such a future mother is initially at risk, she will be put under special control in the antenatal clinic. There will be a need to determine the titer of Rh antibodies in the blood of a pregnant woman.

The burden of a woman whose blood type 1 is positive can also become conflicted if the fetus inherits negative Rh and / or father’s blood.

Pregnancy of a woman whose blood type 2 is negative will be problematic if the spouse has 3 or 4 blood type and the Rh factor is positive. Moreover, if, in the first pregnancy, antibodies that are formed to combat the alien for the pregnant group and rhesus will only be formed, then during the second pregnancy they can turn on the complications of the course of the pregnancy until it terminates and hemolytic disease of the newborn.

Conflict on the Rh factor and blood type, which occurs at different values ​​of the mother and the fetus develops, if the mother has Rh-negative blood, and the fetus is positive; and extremely rarely, if the mother has the first blood group, and the fetus has the second.

What is the significance for doctors of knowledge of the Rh factor of a pregnant woman?

This is a very important indicator for successful childbirth and childbirth. If a woman has a negative Rh factor, she may encounter certain problems during pregnancy. In this case, we will ask the future father of the child to also take a blood test to determine which Rh factor he has. But even if it turns out that both parents are carriers of the negative Rh factor, it is too early to calm down. The fact is that this feature is not always inherited: even with a negative Rh factor in both parents, the child may have a positive one.

Since Rh-negative mothers are at risk from the first weeks of pregnancy, they should in any case be under close medical supervision.

What is dangerous about the difference between the Rh factors of the mother and the fetus?

If the future mother has a Rh factor positive, and the child has a negative one, there is nothing wrong with that. But the opposite situation – the mother has a Rh-factor negative, and the child has a positive – is fraught with the so-called Rh-conflict. Fetal red blood cells are able to pass through the placenta into the maternal blood, and the maternal organism can begin to perceive them as foreign, which will cause an immune response. If this happens, the corresponding antibodies appear in the blood of the pregnant woman. In small quantities, they are not dangerous, but if their concentration rises, antibodies to Rh-positive red blood cells, in turn, can penetrate back to the fetus and try to destroy them. Hematopoietic organs of the child (liver, spleen) will seek to fill the losses and due to the increased load may increase significantly. This can lead to a number of serious problems, generally referred to as hemolytic disease of the newborn. That is why doctors monitor the level of Rh antibodies in the expectant mother: up to 28 weeks, a pregnant woman with a negative Rh factor should take an analysis on a monthly basis, after this period every two weeks. In addition, doctors pay attention to the liver of the fetus. If it is noticeably increased, we have to either terminate the pregnancy or do an intrauterine blood transfusion — today this is possible.

What type of blood our children inherit

  • Parents with the first group of blood can give birth to a child with the first group.
  • Parents with the second – the child from the first or second.
  • Parents with a third – a child with the first or third group.
  • For parents with the fourth – a child with the second, third or fourth.
  • The parents from the first and second – the child from the first or second.
  • Parents with the first and third group – a child with the first or third.
  • Parents with the first and fourth – a child with a second or third group.
  • Parents with the second and third – a child with any group.
  • Parents with the second and fourth – the child with the second, third or fourth.
  • Parents with the third and fourth – a child with the second, third or fourth.

Is it possible to help the future mother with a negative Rh factor and somehow prevent the Rh-conflict?

Yes you can. Recently, a vaccine has appeared – the antirhesus immunoglobulin, which is administered to a woman for a period of 27-28 weeks, two weeks after the previous antibody test, but only if they were not detected. The vaccine is administered intramuscularly and serves to prevent the appearance of antibodies in the current pregnancy. If vaccination is carried out, then the mother no longer needs to be tested for antibodies, since the vaccine gives 100% guarantee of their absence. There is another option – immunoglobulin, which is administered to a woman within 72 hours after giving birth, so that during subsequent pregnancies she does not have problems with Rh-conflict. But, unfortunately, during the pregnancy itself, this drug can not be used.

Does the number of pregnancies affect the appearance of Rh antibodies?

The probability of the appearance of antibodies increases with each subsequent pregnancy, which is why “Rh-negative women” are not recommended to have abortions. As a rule, while waiting for the first child in the maternal organism, some Rh antibodies are produced, they rarely reach the fetus, so that Rh-conflict is unlikely. But in any case, after each pregnancy, whatever the outcome – miscarriage, abortion, childbirth – the Rh-negative woman is surely injected with an anti-Rh immunoglobulin to reduce the likelihood of Rh-conflict in the future.

As medical statistics show, about 85% of the world’s inhabitants have a positive Rh factor and only about 15% have a negative one.

Why is it so important for doctors to know which woman’s blood type is?

If the mother has the first blood group, and the father has any other, the so-called group antibodies may appear in the blood of a pregnant woman, when the child is perceived by the maternal organism as something alien. In order to find out, both spouses at the end of pregnancy (after the 32nd week) must pass an analysis on AB0. Fortunately, problems arise quite rarely and do not affect the course of pregnancy. But it is still important for doctors to be aware of them: if group antibodies are detected, a strong jaundice may be observed in the newborn.

Should a woman during pregnancy adhere to today’s fashionable diets targeted at different blood types?

It is important for the future mother to receive a complete balanced diet, regardless of blood type.

1 negative blood type

1st negative group

Already since ancient times four blood groups are distinguished. Of these, there are those that are more common, and there are – less. Rare blood antigens such as the fourth or third negative are found one in 20 people, or even less. As for the first negative, it is not so rare, therefore, for the delivery of donation occurs quite often. Such a characteristic is laid genetically and occurs on the fifth week of embryo development.

A child’s blood group is formed by dividing the antibodies and antigens of the mother and father, which in the future will form the group and rhesus of the newborn’s blood. In medicine, the division of antigens A and B and antibodies alpha and beta are taken into account. Thus, we can say that the first group of blood (0) is considered the most common. It is universal and well suited for any transfusion. It is possible to make the necessary blood group at the expense of proteins, therefore the first one is suitable for transfusion with the third group. Such information was stored, and boldly used until recently, after which the Ministry of Health banned transfusion with different groups.

Despite the fact that the first blood group is not rare, but it can be said to be universal, it is not allowed to use it for any other groups and Rh factors.

Compatibility of the 1st blood group

Despite the versatility of the 1st group, there are positive and negative Rh factors. Rhesus is a protein that is located on the surface of red blood cells. His absence suggests that the Rh factor is negative in human blood. Thus, the first blood group can be either positive or negative.

Negative rhesus is not a pathology, so it is quite well tolerated by humans. There is no feeling of being unwell or prolonged illness. It is worth noting that the Rh factor plays an important role in blood transfusion, so in any case it should not be ignored, especially if it is some other rare group. For example, if a person has Rh-negative, then in no case can he overflow positive. Although in ancient times positive rhesus transfusions of the second and first groups and any others were allowed only with the same Rh factor. Otherwise, there is a so-called Rh-conflict, which can significantly aggravate the patient’s condition.

Based on all this, it is worth saying that rhesus negative of the 1st group is a rare occurrence, therefore such people are about 15%. The most common positive rhesus of any blood group. If an urgent transfusion is required, then the donor’s compatibility is selected by rhesus, and the antigens are not taken into account. Such a procedure is very rare, but possible, because then it is a question directly of a person’s life.

Features of pregnancy

In medical practice, there are cases when the first blood group provides some difficulties in carrying a fetus. Then it is hard enough to predict compatibility and it is always necessary to keep the development of the baby under control.

Rh-conflict occurs most often when a positive 1st or other group is formed in a baby. In this case, there is no compatibility, which requires immediate medical attention. Therefore, in order to preserve the pregnancy, it is necessary to make a special injection at a certain period, which prevents a possible miscarriage. In other cases, the first group of blood does not provide any danger for pregnancy, especially if there is compatibility with the father of the child. In this case, it is important that the father also has a negative Rh or, on the contrary, is positive, then the child’s development will be successful, which indicates a safe pregnancy.

Therefore, as a conclusion, it can be said that Rhesus plays a rather important role in the development and progression of pregnancy, even despite the blood type of the mother and father.


According to some statements, there is a belief that blood type in some way affects the health of a person, his character and is related to healthy eating. Thus, it is worth noting that people with the 1st blood Rh-negative antigen often suffer from colds, as they have weak immunity. It can also be pneumonia, cardiovascular diseases, diabetes mellitus, various liver pathologies and even a high predisposition to cancer.

As for the physical condition, people with the 1st group are more likely to be overweight and they are encouraged to move as much as possible. Also for this you can follow a certain diet, the food that is in it will be especially suitable for you. Thus, some character of the description of the 1st blood is formed. We can say that the diet should be more vegetarian.

Of course, you shouldn’t refuse meat at all, but you shouldn’t lean on it either. Avoid eating large amounts of sweets and flour products. For example, it is better to limit yourself from the large consumption of whole grains and fresh milk, since they will be too poorly absorbed by your body. Compatibility of foods such as fatty meats and dairy products are the most heavily tolerated by the body. Therefore, do not use them in the daily diet.

It is also worth saying about the character of people with the first type of blood. These are people leaders and hunters. They have a strong spirit and sense of purpose, since it is their blood type that is the first and oldest in medical practice. Compatibility of communication with other people is quite tense, since such people are hard to influence and always defend their rights. Therefore, people with the 1st group have a rather strong and stable character. Someone may not believe such beliefs, but it can be said with accuracy that such descriptions have long been confirmed, because horoscopes and compatibility of marriages are often built on such beliefs.

Some recommendations

Usually people with the 1st group are leaders in sports, they love to win and be strong in all senses. This also applies to work, because for them the working day can end much later than everyone else and it will be a joy for them. The same can be said about health, because it is much stronger than all the other groups. The compatibility of such characteristics is quite high and acceptable as regards marriages and business relations. Even despite the fact that such people prefer leadership, it is easy to communicate with them and find a common language.

As for certain tips, it is recommended to always check the shelf life of products and avoid low-quality food. This is due to the fact that your body is picky in nutrition, even despite its strength. Do not skip fitness classes and spend more time on your health condition. This is especially true for women – go to the beauty salon at least once every two weeks to cheer up and pamper yourself. Thus, you not only restore moral strength, but also spiritual.

Adhere to at least periodically diet, eating as little carbohydrate food as possible – flour products, sweets, meat, and much more, which contains a large number of calories. In this case, your health will be strong and permanent, which will protect you from frequent colds and any other diseases.

It can be said that blood plays a rather important role in shaping not only the character of a person, but also his health; therefore, such chronologies always passed a successful assessment and quite coincide with the predictions. If you still do not know your antigens, do not be lazy and take the analysis. Then you will know for sure why certain circumstances happen to you, as well as why some diseases or extra weight torment you.
