5 Things Your Blood Type Says About Your Health


There are certain factors about our health that we can monitor and change, such as our daily diet and our exercise regime, but then, there are certain factors that we can change, like our blood group. An individual’s blood type is determined by the microscopic substances we all inherit as genes from our parents, and live upon the surface of the red blood cells present within our body.

Research reveals that these microscopic substances make contact with our immune system, and this can change our risk for developing certain diseases. Depending on your blood type, which could be either A, B, AB, or O, you have a greater or lesser risk of suffering from certain diseases, including heart ailments, cancer and memory retention ailments. We’ve made a list of all the common diseases and the risk factors associated with all blood groups.

Here, take a look:

1. Stomach Cancer

The bad news for individuals with blood type AB isn’t over yet, for they also have a greater risk for suffering from stomach cancer. A research attempted to study the health ailments associated with blood types AB, A, B and O, and the results revealed that Abs have a nearly 26% greater risk of developing stomach cancer. While those with blood type A, have a 20% greater risk than blood types B and O.

The reason behind this is the formation of a bacteria, referred to as H. pylori. Medical statistics reveal that nearly 2/3 of the world’s entire population tend to have a gut infection from H. pylori, while those with blood type AB and A tend to have a highly sensitive immune system reaction to this bacteria, which puts them at a greater risk for developing cancer.

2. Heart Disease

Here’s some good news for individuals with blood type O: your blood type can actually cut down your risk for developing heart disease by a whopping 23% as opposed to individuals with other blood groups. Individuals with blood groups AB and B tend to have the highest risk for developing heart ailments. Researchers explain that certain blood types tend to experience a greater risk of inflammation, which eventually develops into a full blown heart disease.


  1. There seems to be a possible error/mix-up in explanation for #5 Ulcers.

    Whereas there is an elevated risk for #1 to 4 health issues for AB, A and B groups versus type “O”, #5 states that it is the “O” blood group that may have increased risk over other blood types for stomach Ulcers related to H.pylori infection (not the case for S. cancer linked to H.pylori infection in AB, A and B groups).

    Is there also a difference (less or more vulnerability to diseases / cancers ) between O+ve and O-ve types?

  2. “You can cut down all your risk factors of chronic and mild ailments with essential nutrients and a gruelling fitness regime. ”
    NO, JUST DO SPORTS MODERATELLY! Too much sport can shorten your life.

  3. I am O Negative with the Rh Factor. What are my chances of getting cancer or any other ailment or disease?
    Thankyou for a reply

  4. I also wonder what having an Rh neg blood type can be linked into. I’m an O-,(which has gone from 15% to 7% of the worlds population in just the last 25 yrs) as was my mother, who suffered from breast cancer, high blood pressure, heart attack, and eventually passed on after a recurrence of estrogen receptor positive breast cancer that metastasized to her lungs. I have early onset memory problems, hashimoto’s thyroiditis for the last 17 yrs, high BP, high inflammatory markers, and psoriatic arthritis, as well as anemia, chronic fatigue, muscle aches & pains, etc. Would love some insight into the Rh negative population.

  5. Thanks for this information, really relevant to me. I am of blood type O RH
    ‘D’ Positive. My Genotype is AA. And I’m presently taking drugs for unfirm Ulcer that is giving relief.
