The Blood Type-Disease Connection No One Tells You About

Is your blood RH positive/+ or negative/-?

Lately I’ve been giving you a lot of information about blood types. But there’s one aspect I haven’t mentioned yet. And that’s the Rh factor.

Many of you have asked me about + and – blood type and wanting to know more about it. So, today, you will learn all about it!

If you want to find out if your blood is + or – a simple blood test can be done to show you that. The result of this blood test reveals if your red blood cells contain a protein called the Rh factor. If it does, then you are Rh positive/+ and if it doesn’t then you are Rh negative/-.

Is the Rh factor important?1

It is vital that you know your Rh factor. Blood transfusions and obstetrics medicine need it in order to save lives.

Take a look at the following blood types in the US

So, why is Rh factor vital?

On the surface of each red blood cells, there’s a set of markers, for example:

Antigens which determine your blood type

  • Blood Type A has A antigens.
  • Blood type B has B antigens.
  • Blood type AB has both A and B antigens.
  • Blood type O has neither A or B antigens.

And the Rh factor which determines if your blood is + or –.

  • When your blood contains this protein – you are Rh positive/+.
  • When your blood doesn’t contain this protein – you are Rh negative/-.

So far so good. But these markers do much more than just reveal to us our blood types.

If someone receives an incompatible blood type transfusion, his body will experience a life-threatening immune response. Because the body processes the antigen of the incompatible blood type as a foreign invader and attacks it.

Furthermore, when it comes to expecting mothers, the Rh factor is crucial for the baby’s survival and safe delivery to term.

If the mother is Rh negative/- and the baby has Rh positive/+ blood, the mother’s immune system will see the baby as a threat and will try to eliminate it.

Luckily, doctors now can help the mother deliver the baby safely with specific medication.

Actually, this is exactly the way the medical community discovered the Rh factor.

The 1939 Case

By that time, the ABO group was already known since its initial discovery in 1900 by Karl Landsteine. This helped revolutionize the world by providing safe blood transfusions to people in need.

However, in 1939 a mother needed a blood transfusion after just giving birth to a still-born child. She received compatible ABO blood from her husband, but something wasn’t right. She experienced an adverse reaction to the blood transfusion.

When researchers looked into it, they stumbled upon the Rh factor which was responsible for the death of this woman’s child and her severe reaction to her husband’s blood transfusion.

Blood-Disease Connection

Since then, a lot of research has been done regarding blood types and illness correlation. Some studies are quite shocking, take a look:

Breast Cancer Risk2

ABO group:

  • 45.88% blood type A
  • 31.69% blood type O
  • 16.16% blood type B
  • 6.27% blood type AB

Rh factor

  • 88.31% Rh+
  • 11.68% Rh-

Venous Thromboembolism Risk3(deep vein thrombosis and pulmonary embolism) , Cardiovascular Diseases Risk4, Mortality and Cancer Risk 5  

High Risk:  Blood type A, B, AB

Low Risk: Blood type O

Periodontal Disease Risk 6

High Risk for Gingivitis -> Blood Type O+

High Risk for Periodontitis -> Blood type B+

Low Risk : AB-


As you can see, there is a connection between your blood type and Rh factor and your susceptibility towards certain diseases.
