It is imperative to know your blood type. But this is not enough yet. The Rh factor plays a special role. It is he who leaves a special imprint on the entire human body. And if such a situation occurs in life when a blood transfusion is required, the doctor will need to know both the group and the Rh factor. Negative blood type occurs in approximately 15 percent of Europeans. What are its features, as well as its pros and cons?
Blood group one is negative. Characteristic
Many people think that blood type, as well as Rhesus, leave a certain imprint on the person himself. Of course, this does not mean that they will all be similar in appearance. But, nevertheless, scientists, having conducted a lot of research, have made some conclusions regarding the very characteristics of the group and the people who have it.
Thus, it is generally accepted that people who have the first blood group, Rh negative, most often suffer from colds due to reduced immunity. But it does not provide exact facts about why this happens and why people have weak immunity.
People with this blood type were also isolated from the general group. And most of them were overweight, which was due to poor nutrition and low mobility. This happens because it is difficult for the body to absorb fats and large amounts of carbohydrates. Therefore, it is recommended to follow a diet.
Regarding character, everyone emphasizes that people with the first group have leadership qualities and are a bit like hunters. They need to achieve what they want at any cost. And often the means and efforts put into this in no way correspond to the result.
What blood type is most rare?
There are four types of blood, as well as two subtypes, which differ depending on the Rh factor. Approximately 87% of people around the world are Rh positive and only 13% are Rh negative. According to statistics, the first negative is considered quite rare, since it occurs in only 4% of people worldwide. However, the most unique group is considered to be the fourth, about 5-6%, with Rh negative within 1% throughout the globe.
Interesting! Although this blood type is found in people more often than some others, it is popularly called blue blood.
Education process
The process of formation of the first negative blood group is very interesting. Blood type is determined by a combination of antigens. This process is very unusual and exciting.
A child with a first negative blood group may have:
- If both parents have blood type O.
- If one of the parents has the first blood group, and the other has the second or third.
- If one of the parents has the second group, and the other has the third. Or both have the second (or third) group.
It should be noted that a man and a woman will never have a child with the first blood group if one of them has the fourth group. But a baby with Rh negative can sometimes be born to Rh positive parents (if they are heterozygous).
Diet tips
In the last century, the theory of the dependence of nutrition on blood type was very popular. The Rh factor was not taken into account at all. It was believed that there were certain foods that were most important for a person with each blood type. They also pointed out unhealthy foods that pollute the body and contribute to the occurrence of diseases.
Here's someone who only ate meat
The origin of all people with the first group is genetically related to the first anthropoid individuals that did not have antigens in the blood. They hunted and ate only meat. Due to drastic environmental changes, it is impossible for today’s “hunters” to consume meat alone; they will also need other healthy products.
The diet was proposed to be followed throughout life. Although the theory has long been refuted by long-term research, it still has followers. Therefore, we present everything that concerns the first blood group.
What is possible
People with this trait are considered obese. A balanced diet requires limiting sweets and flour products.
- Dishes made from lean beef or lamb, fish, and seafood are shown.
- Porridge should be prepared only from whole grains (buckwheat is the most useful).
- You should give preference to dishes made from pumpkin, broccoli, spinach, seaweed with onions, and parsley.
- You can drink green tea, herbal teas, rosehip decoction.
Conventional recommendations will have to be taken critically
Advantages
The first blood group, Rh negative, actually has only one significant advantage. Due to the fact that blood has virtually no antigenic properties (that is, it practically does not cause an immune response to foreign cells), it is considered one of the safest donors for transfusion. As scientists note, such blood can be transfused to everyone, regardless of what Rh factor a person has and what blood group. True, this cannot be done intentionally. This process is allowed only in emergency situations, when there is no “native” blood and it is necessary to resort to transfusion of the first negative one.
What is the Rh factor?
This is a special type of protein (protein) - a substance found on the surface of red blood cells. According to statistics, 15 percent of all people on the planet do not contain this protein in their blood, and they are considered to be Rh negative. The remaining 85 percent of the population is Rh positive. This factor does not have any influence on the physical and intellectual development of the individual. It is important to consider it only during blood transfusion and pregnancy. In these cases, the body begins to fight the foreign protein and leads to serious consequences, including the death of a person during a blood transfusion or a child during a woman’s pregnancy. Therefore, the Rh factor must be taken into account when planning children and in the case when you need to become a recipient or donor.
Flaws
As for the shortcomings, there are many more of them. It should be noted that if the first negative group is universal, that is, it can be transfused to all people, then a person born with it can only be infused with the first negative and no more. Otherwise, it will lead to an immune response, and in extreme cases, even death.
Other disadvantages include:
- Tendency to acute respiratory viral diseases.
- Tendency to diseases of the gastrointestinal tract.
- The risk of hypertensive crisis in men increases.
- Increased likelihood of developing allergic reactions.
- Tendency to be overweight.
In addition, according to statistics, cases of hemophilia in men occur most often if they have the first negative blood group.
The best one is universal
Group 0 (first) blood is called universal because it is believed that it can be transfused to everyone. The fact is that it does not have antigens A and B on red blood cells, which means that the recipient’s body will not begin to produce antibodies against them. Thus, the first group can be considered the best, since its carrier can save any person in case of blood loss.
On the other hand, AB can be transfused only to owners of the same one, and to no one else. At the same time, anyone can become a donor for a person with IV, since AB blood plasma does not contain antibodies to antigens A and B.
You should know that such compatibility exists only theoretically. In modern conditions, it is forbidden to transfuse another group and with a different rhesus. The donor and recipient must have the same blood in both respects. An exception to the rules can be made only in case of urgent need.
Blood transfusion
Particular attention should be paid not only to the blood group itself, but also to Rhesus. Under no circumstances should a person with first negative blood be transfused with blood of any other group. Previously, many years ago, such a transfusion was allowed, however, it only concerned the second blood group with the same Rhesus.
But still, such a transfusion can lead to a worsening of the condition. And if Rh negative blood was transfused, the consequences will be less serious. But if incest suddenly occurs, and the positive is mixed with the negative, then the person’s life will be in danger. In this case, it may be necessary to completely replace all the blood to cleanse it of foreign and dangerous proteins.
Why is negative blood type 1 dangerous in men?
What problems might arise?
If this procedure occurs, a conflict occurs in the body due to the incompatibility of the Rhesus group of the first group, and the patient’s condition worsens significantly. According to scientists, about 15% of men live on the planet with a negative first blood group. To save a person, it is not always possible to select an appropriate donor with a negative Rh factor. Then doctors take risks by transfusing blood with the opposite Rh. This scenario is possible when there is no other way to save a life.
About strengths and weaknesses
They have the most widespread peptic ulcers of the stomach and duodenum. Blood type 1 #8212; This is a high risk of developing hypertension (high blood pressure). There are also a number of diseases that, due to the composition of certain substances, are not spared by carriers of such blood with a negative Rh factor. Blood type 1 provokes the appearance of hemophilia. Men with this group are more likely to suffer from kidney stones. According to doctors, blood type 1 #8212; the main factor that maximizes the risk of the appearance and development of this disease. This is confirmed by statistical data.
Carriers of such blood with a negative Rh factor have a high predisposition to diseases such as tuberculosis, asthma and bronchitis, accompanied by allergic manifestations, to allergic conditions caused by pathologies in the functioning of the bronchi.
Disease Prevention
Such men should definitely limit their consumption of flour, sweets and meat. High-calorie foods in excessive quantities provoke various diseases.
A special liquid or a “river of human life”?
When conceiving a child, blood type is not important. The main factor here is Rh. If a woman and a man have the same Rh factor, then no problems arise in the future. Rhesus conflict #8212 is dangerous; a situation where the Rhesus of a woman and a man does not match. In such cases, the child may develop Rhesus jaundice, which is very dangerous. In addition to the Rh conflict, an AB-zero conflict may also arise, or both conflicts may appear simultaneously. Medicine is constantly evolving, and now there are procedures that can prevent possible complications associated with these conflicts before pregnancy.
Experts consider the first group with negative Rhesus a phenomenon, the solution to which will help the treatment of many male diseases.

Pregnancy
Special attention is paid to compatibility during pregnancy. Everyone knows that Rhesus conflict often occurs. This concept was introduced relatively recently, and that is why obstetricians and gynecologists monitor expectant mothers with negative Rhesus very closely.
The first negative blood group during pregnancy can cause fetal rejection. Therefore, many girls in the first 12 weeks can remain in storage for more than a month, because the body simply rejects, as it seems to it, a foreign organism. They should lead a measured lifestyle, since anything can serve as an impetus for a reaction. And it is noted that their toxicosis is much stronger than that of girls with positive Rhesus.
Problems during pregnancy
Pregnancy for a woman with no Rh factor in her blood has the same consequences, regardless of her blood type. Gynecologists send both spouses to the laboratory to determine Rh.
The expected course of pregnancy may be complicated by an Rh conflict with the fetus if the child receives Rh-positive genes from 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. The child is born with jaundice, liver dysfunction, and anemia. Such a baby is taken under control and receives timely treatment. With age he becomes completely healthy.
During a repeat 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. This threatens miscarriage and disruption of the formation of internal organs.
Modern medicine has learned to combat this pathology by introducing anti-Rhesus globulin, which has the ability to bind and neutralize the effect of maternal antibodies. Rhesus negative women should take care of the future of their children.
How does conflict arise?
During pregnancy, many women do not think about how their Rh and blood type (or father) can affect the baby itself and the process of pregnancy itself.
In fact, everything is very complicated. The first negative blood group in women is dangerous if the father has positive Rh. In this case, the probability of inheriting Rh will be 50 to 50. But most often it is positive Rh who is inherited.
Often, the mother already finds out about such a conflict immediately after visiting the gynecologist, or rather, taking tests. After this, she will be closely monitored and if there is any nagging pain, she will be placed in storage, as the risk of miscarriage and missed pregnancy increases.
Also, a conflict (but to a lesser extent) can arise if the mother has positive Rh and the father negative, and the child inherited the father’s Rh. In this case, the threat of miscarriage is much less, but this does not mean that you should be careless and negligent about your health.
Planning a pregnancy
If a pregnant woman has a negative Rh factor, then she must register as quickly as possible. Indeed, due to a careless attitude, the unborn baby may develop serious illnesses:
- jaundice;
- anemia;
- dropsy;
- underdevelopment;
- disturbance of the speech center and hearing;
- damage to internal organs;
- lack of coordination.
This happens if the father passes on Rh positive to the child, which the body perceives as a foreign element. Of course, there are already certain solutions to ensure that the fetus develops correctly and without complications. Constant monitoring at the antenatal clinic, regular testing, as well as intensive treatment and injections are required. However, if the child, like the mother, is Rh negative, then no conflict will occur during the first pregnancy.
If this is your first pregnancy, then having an abortion is extremely undesirable, since the likelihood of getting pregnant next time is very low, and if you do, the children will most often be born with abnormalities.
The second and subsequent pregnancies are more dangerous than the first due to the fact that the woman’s body has not yet produced antibodies. Memory cells will be present in the blood, which make the likelihood of a conflict higher. Medicine has found a solution for this case too: after 2-4 days, a special vaccination is given, which helps remove aggressive antibodies, which will reduce the threat to the unborn fetus.
Interesting! Anti-Rhesus immunoglobulin is one of the most ambitious achievements.
To avoid many unnecessary complications during pregnancy, it is necessary to prevent the occurrence of conflict in advance:
- If the pregnancy was unwanted and from a man with an Rh-positive factor, then it is extremely undesirable to terminate the pregnancy, since this will cause aggressive antibodies to appear in the blood.
- You should not be negligent about visiting a gynecologist and getting tested.
- If you have been told that you need to go to hospital, then you should not neglect this advice.
- If you want more children in the future and the risk of Rh conflict is minimal, then it is better to postpone pregnancy for some time, about 4-6 years after the first birth.
Second and subsequent pregnancies
The first negative blood group in a woman means that under no circumstances should she have an abortion, especially if the child is the first. If she does this, then the likelihood of having another child is reduced many times, and more often than not, children will be born with health problems.
This happens because the amount of antibodies in the blood after the first pregnancy (even if there was childbirth) increases. And therefore he recommends taking a break between children, so that there are fewer antibodies.
Today, scientists have developed a special vaccine that can prevent the formation of these antibodies and allow a woman to give birth to a healthy child.
Recommendations in the field of dietetics
In the last century, the theory that each group corresponds to a certain diet was quite popular. It turns out that there are foods that are beneficial and, conversely, undesirable for people with certain blood types. As it became known, some food can pollute the human body, which leads to various diseases.
The origin of people who have the first blood group is genetically associated with the appearance of anthropoid individuals who eat exclusively meat food obtained by hunting. As a result of drastic changes that have occurred in the environment, people need other products besides meat. This allows you to ensure the normal functioning of the entire body, receiving the required amount of nutrients of various categories.
Thus, modern nutritionists have developed special nutrition that people of certain categories need to follow. Since the topic of the article is the first blood group, we will now talk about it.
Diet
As mentioned above, people with the first negative blood group are susceptible to obesity. And that is why they need to pay close attention to nutrition. Recommended to eat:
- Lean meats, namely beef, fish.
- Porridge, since there is practically no fat in them (especially if they are boiled in water).
- Vegetables because they contain fiber and no fat. And they are absorbed much better.
In addition, it is recommended to drink green tea and rosehip decoctions.
As for prohibited foods, it is necessary to minimize the consumption of sweets and starchy foods, since they contain a lot of calories, and they also contribute to the formation of cholesterol plaques that interfere with normal blood circulation.
The first negative blood group is considered rare. And therefore, people who own it need to carefully monitor their health, since there are few donors and the environmental situation is getting worse.
Diet
The first group is considered the most ancient, having arisen before genetic changes and the appearance of other species, and in the medical community is considered susceptible to excess weight gain. Let's look at the table and diet for blood group 1.
Dietary recommendations for blood type 1
In nutrition, the most optimal choice is considered to be lean meat and drinking milk. Green tea and drinking herbal infusions are also useful, but it is advisable to avoid black tea. It is also important to follow a diet and avoid citrus fruits and many types of berries.
The main dietary advice would be to abstain from fatty smoked sausages and sausages. You should eat dishes made from zucchini, seaweed, spinach, cauliflower, and parsley.
Some features of pregnancy
Carrying a baby will proceed without any special features if both spouses have the same Rhesus. And vice versa, when the parents are different, there is no compatibility. The first is negative and the first is positive, especially when a woman has a Rh negative sign, then the risks of fetal anomalies and miscarriage are high. This phenomenon is explained as follows. By the end of the third trimester, the fetus begins to synthesize red blood cells and there is a high probability that they will enter the mother’s blood. Probability of events:
- the fetus has the same proteins and is Rh positive;
- they are not there, and accordingly there is no reaction.
Thus, if a woman who is negative receives red blood cells from a baby with the opposite rhesus, then her immune system, in defense, begins to produce antibodies. They destroy the baby's red blood cells, their number rapidly decreases and the fetus experiences a lack of oxygen. And liquid, bilirubin, begins to accumulate in his organs and tissues. As a result, the development of the baby is suspended. This condition is called hemolytic disease of the newborn, or HDN for short.
However, such a conflict may not happen if doctors took the necessary compensatory measures in a timely manner and also prevented such incest during childbirth.
How to avoid the unpleasant consequences of a Rhesus conflict
Parents can quite successfully conceive and give birth to a normal child if the wife has the first group, the Rh factor is negative and her husband has the first positive. In this situation, it is very important for the expectant mother to be under constant medical supervision. To maintain the health of both you will need:
- carry out the procedure for determining the Rh factor of the embryo;
- administration of immunoglobulin to the expectant mother;
- cordocentresis - a method of collecting umbilical cord blood for research;
- When the life of the woman and baby is threatened, artificial birth is induced.
All these activities contribute to the birth of a healthy baby and maintain the health of the mother.
Blood type 2 with Rhesus having a minus sign
The second negative blood group, like the first positive, appeared quite a long time ago. It is believed that when a primitive individual began to engage in farming and hunting, the second negative was formed. Today it is widespread throughout the planet, just like the first negative one. For people who have them, there are no difficulties in finding a recipient, since the admissibility of compatibility is high. Due to the fact that representatives of the 2nd blood group were engaged in arable farming, their digestive system has some differences. For example, she has learned to process carbohydrates better than proteins and fats. Therefore, people in this group eat more fruits and vegetables. In addition, owners of the second negative are more susceptible to diseases associated with the heart and blood vessels. They are more difficult to bear overloads. They should exercise daily and plan their diet so that it is dominated by plant foods. Protein, which is so necessary for the body, can be obtained from fish products, which are allowed to be consumed daily.
