What’s your blood type? Did you know that we are more vulnerable to certain diseases depending on the type of blood? More than a century after the Austrian Karl Landsteiner discovered the blood groups (O, A, B, and AB), science continues to investigate its important role.
The blood group influences the risk of heart disease and, as science has found, having one type or another of blood predisposes us to other health disorders. Find out what is the first preventive measure that is in our hands.
Heart disease according to blood group
A study by Brigham and Women’s Hospital and Harvard Medical School in Boston found that people with the AB blood group are at highest risk of suffering from a heart disorder, 23% more than the O group. These are followed by people with blood group B (11%) and group A (5%).
Brain diseases according to blood group
The AB blood group is also more vulnerable to cognitive impairment (memory loss, language problems, attention problems), as the results of a study conducted by the University of Vermont School of Medicine and published in the Journal Neurology. Cognitive disorders that may precede dementia.
Stomach diseases according to blood group
A study by the American Journal of Epidemiology showed the relationship between the blood group and the greater or lesser risk of stomach cancer. Specifically, the study found that people with blood type AB and A are the most vulnerable. The response would be in the bacteria called Helicobacter pylori, with ability to activate in these blood groups and, thereby, increase the risk of stomach cancer.
The same bacteria are also involved in the onset of gastric ulcers. In this case, as several studies have pointed out, it would be peoples with the blood group O the most vulnerable.
Diabetes and blood group
Science has also inquired into the relationship between diabetes and blood type. One of the most recent studies has been conducted in France, and published in the journal of the European Association for the Study of Diabetes. According to the results, people with blood group B would be the most vulnerable to type 2 diabetes, followed by people with blood group AB and A. Those with the least risk of having high blood sugar would be people with group O.
