The reasons why you should know your blood type

Suddenly someone asks you and you have no idea what your Blood type. "I think … A +, no … it was 0 -…, well, I don't know," you just answered. If you thought it was not important know him, you're wrong. According to a study published in 'Wiley Interdisciptionary Reviews: Systems Biology and Medicine', knowing it can help you.

You may have heard that the blood group AB is the weirdest to find (Only 0.6 of the population has it). Although it is true, if you compare the 8 different combinations that can be made with A, B, O and D + or D-, the percentages They change a bit depending on ethnicity.

How does it affect the blood type what do you have for your health? From risk of heart disease, dementia, norovirus to urinary tract infections, knowing this simple fact can help. While studies they are inconclusive about the cause and the effect, the research highlights the importance of knowing the type you have to know how it could affect your well-being.

Heart attacks

Your blood type helps determine if you are at risk of suffering a heart attack, as suggested by research presented in 'Heart Failure 2017-4th World Congress on Acute Heart Failure'.

Women belonging to group 0 have more difficulty getting pregnant due to lower quality and lower ovum count

The researchers analyzed data from more than 1,300,000 people from nine previous studies and concluded that those with blood type A, B or AB were 9% more likely of having a heart attack than those of type 0. What causes the increased cardiac risk is not exactly clear, but one possibility could be because people with this type of blood have higher concentrations of a certain protein at the initial time of hemostasis, what is called von Willebrand factor.

Blood clots

Danish researchers studied how blood type interacts with a genetic predisposition for Deep venous thrombosis (DVT) or blood clots in the lower legs that can go to the lungs and increase the danger of death. After analyzing data from approximately 66,000 people for more than 30 years, they discovered that people with type AB, A or B had a 40% greater risk of suffering from it than people with type 0.

When the scientists conducted an additional analysis to see which factors have the greatest impact at the population level, they realized that those who were AB were 20% more likely to suffer from it. genetic mutations accounted for 11%, the overweight 16% and smoking 6%

Stomach cancer

Researchers have discovered that people with blood type TO they have increased risk of stomach cancer. But research published in 'BMC Cancer' shows that AB type are also in danger. Using genetic data from a large number of cases and controls, experts found a link between the disease and both blood groups in Chinese populations. A review of 39 previous studies confirmed their findings.


Scientists at the Albert Einstein School of Medicine and Yale University discovered in 2010 that women belonging to group 0 they had more difficulty getting pregnant than the rest due to lower quality and a lower ovarian reserve count. The study involved 560 women of an average age of 35 who were undergoing treatments of fertility

Those with blood type A, B or AB are 9% more likely to suffer a heart attack than those in group 0

It is believed that high levels of a hormone (follicle stimulant or FSH) are an indicator that this reserve is decreasing more quickly, which can reduce the chances of a pregnancy once the woman reaches 35 or 40 years.
