If Your Blood Type Is O, Here Are 6 Things That Are Worth Knowing About

For the first decade of the twentieth century, human blood was classified by Austrian physician Karl Landsteiner into four known types. It is no secret that it is important to know the blood group of a person in an emergency, because the matching of blood is very important for safe transfers. However, it appears that blood traits can also affect our health, and, as some believe, our wealth and personality.

We have studied scientific facts and strange theories about the type of O blood and we can’t wait to tell you what we found.

1. How are blood types determined?

Blood groups or blood groups are classified according to the presence or absence of specific antigens that can lead to an immune response if foreign to the body. These antigens can cause the patient's immune system to attack transfused blood. That is why it is so important to know your blood type and be aware of the safe fit of blood transfusions.

2. Enter blood properties

There are four major blood types that are determined by the presence or absence of A and B antigens on the surface of red blood cells and A and B antibodies in plasma. In addition to antigens A and B, there is a protein called Rh factor that may be present or absent. In total, it consists of 8 types of blood: A +, A-, B +, B-, O +, O-, AB +, and AB-. Type O blood does not have A or B antigens in red blood cells, but rather A and B antibodies in plasma. Type O + is the most common blood group, comprising 37% - 53% of people in different ethnic and racial groups.

3. People with type O blood are global donors.

People with type O + blood can donate blood for all four groups, but only for people with a positive subgroup RH (O +, A +, B +, AB +). O-type red cells can be transported to all eight subgroups, creating a global blood group that is always needed for emergency transfers. Type O blood transfusions are made in an emergency, when it is important to save the patient's life before the crusade test is completed. What's more, O-blood is the safest type for newborn babies with immune systems underdeveloped.

4. People of type O can only receive blood of type O.

People with type O + blood can receive blood from people with both O + and O-, while people with type O blood can only receive the same type O blood. In emergency situations where there is a deficiency of the blood type O-, it can be replaced by the blood type O +.

5. Health risks

According to scientists, there are ways in which blood biochemistry determines our health. Although the effects of blood types on our health are still being investigated, there are certain theories about the health risks and benefits for people with different blood types.

In particular, it is considered that people with blood type O may be more susceptible to certain types of bacterial and viral infections than other blood groups, including severe groups such as plague, cholera, mumps and tuberculosis. Some studies also show that blood group O members have a 35% higher rate of duodenal ulcers compared to people with blood types A, B and AB.

6. Health benefits

People with type O blood have a lower risk of coronary heart disease compared to people with blood types A, B and AB. Studies show that individuals with no blood type have a 25% higher risk of developing pancreatic cancer than people with blood group O. In addition, people with blood group O have a lower risk of developing blood circulation and disease.

However, maintaining a healthy lifestyle and managing health risk factors are very important to avoid disease, regardless of your blood type.
