Did you know that blood type O is the most common blood type? Not only that. There are many facts about blood type O that are interesting to observe.
A person's blood type is determined by the type of antigen on the red blood cells. This blood group is divided into four types, namely A, B, AB, and O.
In addition, blood types are also classified based on the rhesus (Rh) factor. If a person's blood contains the Rh factor, it means he or she is said to be rhesus positive. On the other hand, if a person does not have the Rh factor in his red blood cells, he is said to be rhesus negative.
Facts About Blood Type O
Of the four blood types, O is the most common blood type in the world. In addition to these facts, the following facts about blood type O are also interesting to know:
1. Those with blood type O are universal donors
Unlike blood types A, B, and AB which have antigens, blood type O is the only type of blood group that does not have antigens. This makes blood type O less at risk for blood transfusion reactions.
Therefore, someone who has type O negative can donate blood to all blood types. This makes blood type O dubbed the universal blood donor.
2. Blood type O is mostly stored in blood banks
Almost all blood banks and hospitals around the world ask for more blood type O supplies (especially blood type O rhesus negative) to be kept more.
This is because type O blood is considered to be at a lower risk of causing a transfusion reaction, so it can be used at any time by patients who need emergency blood transfusions.
However, this does not mean that owners of other blood types need to be discouraged. Every drop of donated blood, regardless of blood type, has such a big role in saving someone's life.
3. Women with blood type O are considered more at risk of developing fertility problems
This assumption is still a controversial debate. There are studies that show that on average women with blood type O have more FSH hormones than women with other blood types.
This high FSH level can cause the number of egg reserves in the uterus to be less, so it is at risk for difficulty getting pregnant. Meanwhile, there are also other studies that refute this assumption and find no link between the risk of fertility problems with blood type O or other blood types.
If you are a woman with blood type O, there is no need to worry too much. Fertility conditions are not solely determined by blood type, how come. There are a number of other factors that also influence, ranging from lifestyle, age, diet, heredity or genetic factors, side effects of drugs, to certain medical conditions.
To maintain the health and fertility of the body, you still need to live a healthy lifestyle by eating nutritious foods, exercising diligently, not smoking and consuming alcoholic beverages, and practicing safe sex.
4. The effectiveness of a special diet for blood type O
The blood type diet is a dietary pattern that is adapted to a person's blood type. This diet method advises those with blood type O to eat foods high in protein and low in carbohydrates, such as lean meats, fish, vegetables, fruits, and olive oil.
Although it is quite widely followed by some people, the fact is that until now the effectiveness of the blood type O diet has not been proven to be healthier and better than other types of diets. Therefore, no matter what type of blood type you have, you are still advised to eat healthy foods with balanced nutrition.
5. The choice of exercise for owners of blood type O
In addition to the diet menu, there are other types of exercise that are recommended for owners of blood type O. This blood type is more suitable for doing sports with high intensity movements, such as jogging, swimming, cycling, zumba, or jumping rope.
However, not only for those with blood type O, people from other blood types will also get the benefits of exercise which is good for health. The key is the exercise needs to be done regularly and regularly.
nowHere are five facts about blood type O that are interesting to know. However, you need to remember, some facts of blood type O above still need to be proven further. So, if in doubt, don't hesitate to ask your doctor.
