If all you know about your blood type is its name the fact that it is red, you have a bit of learning to do. Your blood type isn’t just limited to a group, it is also an indicator of medical conditions that may affect you specifically because you have that blood group.  

Strange but true, there is a correlation between blood type and disease risk. 

Co-relation Between Blood Type And Disease Risk

Your blood is made up of various components and cells such as white and red blood cells that fight infection and carry oxygen, respectively. There are also platelets that help create a blood clot. Then there’s plasma cells that provide nutrients and are responsible for hormones as well as antibodies to fight infections. 

Finally, there are other factors such as antigens that determine your blood type and your blood is categorised as A+, A-, B+, B-, O+, O-, AB+ or AB-.

When the antigens come in contact with bacteria, they trigger a response from your immune system. And based on your blood type, your body begins to either fight against these or gives in. 

How Your Blood Type Determines Your Health 

Let’s take a look at how your blood type and disease risk can play a role in your well-being. 


When compared with the O group, participants with A or B type blood have higher odds of developing diabetes. According to a team of French researchers, women with blood type B positive appear to face a 35 percent greater risk of developing type 2 diabetes than women with blood type O negative.

Gastric cancer

According to studies, if your blood type is A or AB, you are at higher risk of developing stomach cancer. Additionally, if you have A, B or AB blood types, you may have an increased risk of pancreatic cancer. 

In fact, studies say that Type A blood has been found to have a higher risk of stomach cancer specifically, compared to those with other blood types. The ABO gene also plays a role in heightened cancer risk. This gene has been connected to other cancers, including lung, breast, colorectal, prostate, liver, and cervical cancers.


If your blood group is A, you may have more trouble handling stress. It is because you have heightened levels of stress hormones called cortisol in your body. Stress, when left unchecked, can lead to more serious health problems like high blood pressure, heart disease, obesity, and diabetes.

Type A group also have quicker stress recovery rates than the type O group. The mantra to reduce stress in your daily life is to lead a healthy lifestyle.
