People with type O blood are more likely to suffer from stomach problems, gout, etc. than people with other blood types.
Human blood was first classified into four famous categories in the first decade of the 1900s by Karl Landsteiner, an Austrian physician. Determining blood type does not simply help us when blood transfusions are needed. Blood types can also affect health.
Blood type O is the most common blood type in the world. 37-53% of the world’s population of different races have this blood type. In Vietnam, this rate is about 42.1%.
Why can type O blood be transfused to other blood types?
There is a special thing that people with type O + can give blood to all 4 blood types O +, A +, B +, AB +. More specifically, blood type O- can give blood to all 8 blood groups because there is no antigen A, B and Rh so it is not recognized and attacked by the recipient’s immune system. This has made O- group a global blood type and is always needed in cases of urgent need for blood transfusion, especially when the patient’s blood type has not been identified.
Although people with O + or O- blood types can pass blood to other people with type O blood, people with O + blood can receive blood from people with O + and O- blood types. People with type O blood can only accept blood from people with type O blood.
Because of this special feature, in some countries around the world, such as Japan, it is also based on that to identify the personality of people with type O blood as kind, generous, sociable and very successful in terms of finance. Television programs, newspapers in this country even publish personality tests by blood type and compare the compatibility of … love between blood types.
Although it is not known exactly whether blood type affects personality, scientists can identify a number of health problems related to blood type.
