What are the dangers of having positive blood type O

O type blood is a blood type that many of our friends want, because this blood type is universal for AB blood type. Once we need a blood transfusion, we can give blood to others. In addition, people with O type blood have more gray matter in their brains and are less likely to develop Alzheimer's disease. However, O-type blood is not very good either, because when O-type blood is positive, it means that men are prone to impotence and women's egg count will decrease, among other symptoms.

After investigating the brains of 189 people, a British university concluded that people with type O blood have more gray matter in their brains and are less likely to suffer from Alzheimer's disease. In addition, people with type O blood have a 30% lower risk of developing blood clots than people with other blood types.

Type O men are four times less likely to suffer from impotence than other blood types, and type A men are most likely to suffer from erectile dysfunction; however, for women, the quality of eggs in type O women is slightly worse than that of type A women, with only half the number of eggs as type A women. If they don't get pregnant when they are young, it is easy to use up the eggs.

Type O people are also less likely to suffer from Alzheimer's disease. A British university scanned the brains of 189 people and found that Type O people have more gray matter in their brains. Gray matter is the base camp of human intelligence and the center of brain computing. Type O people are prone to generating gray matter when they are young, and are less likely to get Alzheimer's disease when they are old.

People with type O blood have a 30% lower risk of developing blood clots than other blood types. Type B blood is the most prone to blood clots, so people with type B blood are more likely to die at a young age.

In addition, studies in various countries have also shown that people with type O blood are more resistant to malaria, stomach cancer, or liver cancer, and are more resistant even if they get sick.

Common blood types

A, B, O blood types

ABO blood type divides blood into four types based on the presence or absence of antigen A and antigen B on the red blood cell membrane. If only antigen A is on the red blood cells, it is type A; if only antigen B is on the red blood cells, it is type B. If both A and B antigens are present, it is type AB; and if neither of these two antigens is present, it is type O. The serum of people with different blood types contains different antibodies, but does not contain antibodies against their own red blood cell antigens. For example: Type A blood serum only contains anti-B antibodies. Among the people of all ethnic groups in my country, type A, type B and type O blood each account for about 30%, and type AB accounts for only about 10%.

Rh blood type

Human blood that has the same antigen as rhesus monkeys on its red blood cells is called Rh positive blood type, while blood that does not contain this antigen is called Rh negative blood type. Among the Han people and most ethnic minorities in my country, Rh positive blood type accounts for about 99%, and Rh negative people account for only about 1%. The Rh blood type system is the most complex of the red blood cell blood types. More than 40 Rh antigens have been discovered, among which the D antigen has the strongest antigenicity. Therefore, red blood cells containing D antigen are usually called Rh positive, while red blood cells lacking D antigen are called Rh negative.
