8 Things That Are Worth Knowing About If Your Blood Type Is O

Human blood was first classified into 4 types known in the early 1900s by Karl Landsteiner, an Austrian doctor. It is no secret that knowing blood type is important for emergencies, as a blood match is crucial for safe transfusions.

However, it turns out that the characteristics of blood can also influence our health and, as some people believe, also our fortune and personality.

We study scientific facts and curious theories about Type O blood and are eager to tell you what we have discovered.

Blood types, or blood groups, are classified according to the presence or absence of certain antigens that can trigger an immune response when they are foreign to the body.

These antigens can make the immune system of the patient attack the transfused blood. This is why it is so important to know your blood type and to be aware of the safe matches for blood transfusions.

There are 4 main blood types determined by the presence or absence of A and B antigens on the surface of red blood cells and A and B antibodies in the plasma.

In addition to the A and B antigens, there is a protein called the Rh factor, which can be present or absent. Altogether, this makes up 8 blood types: A +, A-, B +, B-, O +, O-, AB +, and AB-.

Type O blood does not have A or B antigens on red blood cells, but it does have A and B antibodies in plasma. The O + type is the most common blood type, which accounts for 37% to 53% of people in different ethnic and racial groups.

People with type O+ blood can donate blood to all 4 groups, but only to people with the positive RH subgroup (O +, A +, B +, AB +).

Type O- red blood cells can be transfused in all 8 subgroups, making it a universal blood type that is always needed for emergency transfusions.

Type O- blood is transfused in emergencies when it is important to save a patient’s life before the crossmatch test is completed.

Additionally, Type O- blood is the safest for newborns whose immune systems are underdeveloped.

5. Type O Blood Individuals Can Receive Type O Blood Only

People with type O + blood can receive blood from people with types O + and O-, while people with type O- blood can only receive the same O- type blood. n emergency cases when type O- blood is in short supply, it can be substituted with type O+ blood.

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

In particular, people with blood type O are considered more susceptible to some bacterial and viral infections than other blood groups, including severe ones, such as plague, cholera, mumps, and tuberculosis.

Some studies also show that individuals with blood type O have a 35% higher incidence of duodenal ulcers compared to people with blood types A, B, and AB.

3. Health Benefits

People with type O blood have a lower risk of developing coronary heart disease compared to people with blood types A, B, and AB.

Studies show that individuals without type O blood have a 25% higher risk of developing pancreatic cancer than people with type O blood.

In addition, people with type O blood are less likely to develop circulatory diseases and cognitive disorders.

However, maintaining a healthy lifestyle and controlling health risk factors is crucial to prevent disease, regardless of your blood type.

You may have heard of so-called  “blood type diets”  that claim that eating certain products that match your blood type will help you maintain good physical shape and health.

Despite their great popularity, blood type diets lack scientific evidence and are not universally recognized.

Nutritionists suggest that it is better to follow a personalized diet, taking into account your individual health status, rather than a diet-related to your blood type.
