Can blood types also affect the risk of death? Japanese women’s weekly Women’s Own reported on the 11th that people with type O blood have a higher risk of death than other blood types when they encounter major accidents.
Tokyo Medical Dental University studied and analyzed the data of 901 patients, all of whom were seriously ill patients who were rushed to hospital after a major accident. The results of the study found that the mortality rate of patients with type O blood is more than twice that of patients with other blood types.
According to the report, the reason for this phenomenon is that the concentration of coagulation factor varies from blood group to blood group.
Because the concentration of partial clotting factor of type O blood is lower than that of other blood types, people with type O blood have worse clotting function and stop bleeding more slowly. In general, such differences occur only when a person has a major accident, the researchers said.
