Do you know the role of your blood type?

You’re probably thinking about how it lets you know who you’re compatible with. And who you can donate or receive blood from.

But your blood type plays a larger role than this.

It categorizes your blood according to what’s in it — antigens, including the Rhesus, or Rh factor.


Antigens are a type of protein in red blood cells. Based on the type of antigen, your blood will be categorized as Type A, Type B, Type AB, or Type O.

When these antigens come in contact with unfamiliar substances like bacteria, they trigger a response from your immune system.

The Rh factor is also a substance in your red blood cells. This is where the + and — signs next to your blood type are important.


Because you’re considered Rh-positive (+) if you have the Rh factor and if you don’t have it, you’re Rh-negative (-).

But when proactive with your health, this identification can help you avoid health problems.


For example, people with A, B, or AB blood types are more likely to have cardiovascular disease or experience a blood clot than people with type O blood.

While people with type O blood are more likely to have a bleeding condition.

Your blood type also plays a significant role in brain function and memory loss.

People who have blood types A, B, and AB are up to 82% more likely to develop cognition and memory problems — which can lead to dementia — compared to those with Type O.

And people with Type A blood have been found to have a higher risk of stomach cancer, compared to those with other blood types.
