Health secrets of more than 40% of the population

Master - Doctor Nguyen Thi Phuong (Endocrinologist - Nam Sai Gon International General Hospital) said that the blood group system is a collection of one or more antigens under the control of a single gene or a group of closely linked, similar genes. According to the update to 2023, there are currently 43 blood group systems recognized by the International Society of Blood Transfusion. The ABO blood group system is responsible for 4 main blood groups: A, B, O and AB.

The ABO blood group system is one of the most clinically significant and familiar major blood group systems for determining blood type based on the presence of A and B antigens on the surface of red blood cells.

The ABO blood group system is responsible for four main blood types: A, B, O, and AB.

Blood type O - universal blood type

According to Dr. Phuong, blood type O is known as the “universal blood type” because it can be transfused to the remaining blood types (A, B, AB). Blood type O is considered a safe blood type for transfusion because it does not have A or B antigens, and there is no risk of reacting to these antigens. This makes blood type O a good choice for people who need blood transfusions. However, blood type O also has both anti-A and anti-B antibodies, so people with blood type O can only receive blood from people with the same blood type O as themselves.

Therefore, blood type O is also considered the "friendliest, most generous and open-minded" blood type.

Blood type O is known as the "universal blood type" because it can be transfused to other blood types.

Health characteristics of blood type O

Dr. Phuong said that people with blood type O often have a special protein that is about 20 to 30% lower than people with blood types A, B or AB. The main protein is von Willebrand factor - VWF, which helps platelets stick together, forming blood clots to stop bleeding when there is a wound. Therefore, people with blood type O may have a lower risk of thromboembolism.

Additionally, certain malignancies have been reported to be more likely to occur in individuals according to blood type characteristics.

Stomach cancer appears to be more common in people with blood type A, stomach and duodenal ulcers occur more often in people with blood type O, and pancreatic cancer appears to be more common in people with non-O blood type (A, AB, or B).

In addition, initial research results show that people with blood type A or AB are at higher risk of developing and being more severely infected with Covid-19 than people with blood type O. This means that people with blood type A and AB may experience more severe symptoms and require more aggressive treatment than people with blood type O.

"However, regardless of your blood type, the most important thing is to maintain a scientific lifestyle, exercise regularly, maintain an ideal weight, and have regular health check-ups. Doing these things well will help prevent and limit complications of cardiovascular, metabolic, infectious, and cancer diseases," Dr. Phuong recommends.
