Blood grouping (also called blood typing) is a way of categorizing human  blood into groups, based on the presence of  sugar molecules on the blood‘s red cells.


Did you noticed people have recently linked some hoaxes and lies with blood groups and human behavior. Some even went to the extent of preparing dietary advices for persons with specific blood groups and propounded that some particular groups cause some diseases.


What’s right, and what’s not about all of these?


Here, I’ll present to you ten facts you’ll want to know about your blood group;


  1. Blood groups are numerous

Currently, there are well over 400 blood grouping systems in the world, with the ABO and Rhesus grouping systems being the most medically relevant. Others that are less important to these are Dell, Duffy, Kidd, Lutheran, Lewis,  P,  MNS and  I.


  1. Human behavior and blood groups

There are currently paltry definite scientific affirmations connecting blood groups and human personalities.


In 2011, Dr. Hobgood hypothesized that people with blood type O are likely to be non-submissive, nonperfectionist and aggressive, his grounds for his conclusion were on some genetic reasons which related personality changes and catecholamine genes. Catecholamine is the general name for hormones like adrenaline which is responsible for our alertness – the flight or fight hormone.



If you’re in Japan, expect your mouth gapped, there are several eye-widening believes about blood group and personalities. In fact, the belief is so common that according to Dan’s blog  ‘Now I know,’ he categorized group A to be ‘creative’  sensible, etc. and group O to be rude!

  1. Heart attack and blood group


Some blood groups are associated with some inflammatory processes like cancers and cardiovascular diseases.



Non-type O individuals (blood type A, B, and AB) have 25% higher levels of inflammatory-promoting substances like the Von Willebrand factor (vWF), this increases the likelihood that these individuals may come down with heart diseases.


  1. Norwalk Viruses on blood group B -no work


Type B individuals are lucky on this, and they’ve got almost no worries about Norwalk viruses (a member of the Noroviruses) as studies have shown Norwalk viruses easily get attached to blood group O red cells compared to blood group B.


The affinity of the virus for non-blood group O,  is due to the absence of the sugars – N-acetyl D-galactosamine transferase and D- galactose – from the red cell’s surface.


  1. Hepatitis viruses and Blood group


Several studies done on varying viruses have shown inconsistency, and conflicting results were often observed.  There seems to be a real relationship between some viruses and blood types.

In 2012, a study conducted by Shavakhi et al. suggested non-O blood groups as a genetic risk factors for HCV infection and liver fibrosis progression.

  1. Malaria and blood group

Group A, B, and AB red cells are known to have the abundant presence of glycosylated substances (sugar-like antigens) on their surface, this increases their chances of stalking together like coins, this is  called ‘rosette formation’.

During tropical infection such as malaria, the presence of A and B antigens acts as a receptor for malaria causing parasite  P.falciparum. It follows that Group O individuals are prone to forming fewer rosettes, hence likely to get less severe malaria.

  1. Group O and Cholera

Cholera toxins don’t bind to intestinal receptors of A, B and, AB individuals.

Cholera is twice likely to affect blood group O individuals than other blood groups.


  1. Did my blood group caused my Diabetes?

As a multifaceted metabolic disease, Diabetes hasn’t really been implicated in blood group physiologies, many studies done on the possibility of their associations show a derangement in the established scientific facts known.


Researchers have opined that this disjointed relationship could be due to differences in geographical and ethnic factors.


  1. Some blood groups go with some cancers.

Some forms of cancers can reduce the antigenic population of ABO genes on solid tissues surfaces; Most common cancers, however, don’t affect red blood cells antigens.


What is documented is that; Group A individuals are susceptible to breast Cancer while group O is associated with skin cancer.

Blood type O Rhesus D negative individuals are also believed to be lung cancer susceptible.

  1. blood group O and depression

Dr. Irvine and Miyashita once verified that blood type O persons are susceptible to depression in a specific pattern.
