As we all know, due to the influence of genetic factors, the blood type has its unique blood type determined from the day of birth.
From a medical point of view, blood type is hereditary, and blood type is determined by the combination of three genetic factors , A, B, and O. Based on the blood type of the parents, the blood type of the child born in the future can be determined.
According to the parents chromosome group , the genetic rules are diverse. Among them, the A gene and the B gene are dominant genes , and the O gene is a recessive gene. That is to say, if the A and O genes exist at the same time, then the expression is type A. ;B and O genes coexist, which manifests as B type ; A and B genes coexist, which manifests as AB type.
O blood type :
O blood type is also one of the blood types. Because blood types can be divided into type A, type B, type AB and type O . Type O blood is found only on the surface of and red blood cells and contains neither A nor B antigens. It is commonly known as universal blood transfusion recipients.
Do people with blood type O have good physical fitness? Do people with type O blood live longer?
The reason why type O blood is called universal blood by many people is because it does not have A and B antigens. For people with these two types, if they need a blood transfusion, type O blood can come in handy.
People with type O blood generally have better physical constitution, are relatively strong, and have certain resistance and prevention ability to some minor diseases. Compared with other blood types, people with type O blood have better physical fitness and rarely get sick!
For people with type O blood, a study in the United States found that such people have a relatively small risk of blood clots. A study by the Harvard School of Public Health found that they have a relatively lower risk of heart disease.
However, there is no success or failure. Although people with type O blood have better physical fitness, they also have obvious shortcomings. Let’s take a look below!
Reminder: People with type O blood may have these 4 shortcomings. Pay more attention to
- people with type O blood have more sensitive stomachs and are more likely to suffer from stomach pain
Why is it said that people with type O blood are more likely to suffer from stomach problems? What about ?
People with type O blood have a better appetite, mainly because the digestive system and absorption capacity of type O blood are better, because people with type O blood have stronger gastric acid secretion, so once they eat irregularly or often eat spicy food, it will cause The stomach secretes excess gastric acid, which can cause stomach upset!
- Type O blood has weak coagulation function and is prone to bleeding disorders
A study by the University of Minnesota in the United States found that type O blood has less protein that can help blood clot, so the risk of cerebral thrombosis is relatively low, but because it helps blood clot The protein is relatively small, so it is easy to cause coagulation dysfunction, thereby causing bleeding problems!
- Pregnant women with type O blood have certain fertility problems
Women with type O blood have insufficient ovarian reserve because research has found that women with type O blood have twice as much follicle-stimulating hormone as those of other blood types. When follicle hormone is high, there will be signs of insufficient ovarian function reserve!
- susceptible to diabetes
Many studies have found that because people with type O blood have lower insulin levels, if they do not pay attention to their eating habits or frequently consume high-sugar foods, it will increase the work pressure of the pancreatic islets. It leads to excessive secretion of insulin and can lead to the troublesome diabetes!
Study shows: People with type O blood are nearly 20% less likely to contract COVID-19 than other blood types
According to Daily Mail , a study by DNA identification company 23andMe has found more evidence that blood type coding may Impact on the risk of contracting coronavirus: People with type O blood are nearly 20% less likely to test positive for COVID-19.
The research team recruited more than 750,000 participants, including 10,000 people who tested positive for COVID-19. Researchers found that individuals with type O blood were 9% to 18% less likely to test positive than people with other blood types.
According to the results, it was confirmed that people with type O blood were less likely to be infected with the new coronavirus than other blood types!
