If you have this blood type, don't ask why you are prone to ... diarrhea

There is a blood group that makes you very susceptible to diarrhea, especially when traveling.

As you may know, there are 4 blood types in this world: A, B, AB, and O (all of which can be negative or positive).

Blood type is regulated by genes obtained from parents. But you know, in these 4 blood groups, there's a group that makes you very susceptible to . diarrhea.

People with blood type A are more likely to suffer from diarrhea when traveling.

Those are blood type A. Please give your condolences.

Specifically, people with type A blood are very susceptible to E. coli strains - the type that can cause diarrhea - in particular "diarrhea when traveling" - referred to as "travel diarrhea". (traveler's diarrhea - TD) . That is the conclusion given by Washington University of Medicine.

What is "travel diarrhea"? As its name suggests, it is diarrhea that happens when you go to another country, another land. The disease is not common in developed countries. But for developing countries where sanitation conditions are somewhat unsecured.

Blood type A is more easily linked to E. coli, easily causing diarrhea than other groups.

The symptoms of TD are not the same for each person, but often involve continuous peristalsis, dehydration due to diarrhea in 24 hours when going to a new location. And especially for people with blood type A, they have a much higher risk of getting this disease.

To find out why, experts at Johns Hopkins University have experimented with the possibility of E. coli infection on each blood type . The results are: "Blood type A is more easily linked to E. coli, easier to cause diarrhea than other groups". And obviously, the symptoms are also more likely to break out at a faster rate.

Blood type is regulated by genes obtained from parents.

After a period of research, the researchers found that E. coli strains can produce a protein with properties that help them easily attach to blood type A. More specifically, they prefer a molecule named glycan in A's blood - usually spreads over small intestine cells. This makes it easy for E. coli to distribute toxins, making the host sick much faster.

Fortunately, this protein does not appear in dangerous E. coli strains, which kill millions of people. But even so, experts are planning to create a vaccine that will protect the blood group A - the group likes to travel, and children who live in areas with unsafe sanitation .
