In our daily lives, the most common blood types are A, B, O, and AB blood types. Among them, people with blood type O can account for about 30%. It is precisely because this blood type is very common that everyone is familiar with blood type O. However, being familiar with blood type O does not mean that everyone is familiar with it. Therefore, let's talk about the disadvantages of blood type O.
I don't know if you have heard of hemolytic disease of the newborn. The cause of this disease is that the mother's blood type is type O, but the baby's blood type is type A or B. If the symptoms of hemolytic disease of the newborn are mild, the harm to the baby is not significant, except for severe jaundice after birth. However, if the symptoms are severe, it can bring great harm to the newborn, causing anemia, hepatosplenomegaly, and even heart failure. But not all mothers with type O blood will develop hemolytic disease of the newborn when carrying babies with type A or type B.
In addition, studies have shown that people with type O blood have a higher mortality rate after severe trauma compared to those with type A blood, type B blood, and type AB blood. Excessive bleeding is the main cause of death after being severely injured. Relevant researchers speculate that the higher mortality rate of people with type O blood is due to the lower coagulation factor content of type O blood compared to type A blood and type B blood. However, this is only speculation and requires extensive experimental research to prove. Therefore, friends with blood type O do not need to worry too much, regardless of their blood type, they should pay attention to protecting themselves in daily life.
