What Are the Cons of Blood Type O Positive? Blood type O is the most common blood type in the world, with about 38% of people having this blood type. Blood type O is characterized by the absence of A or B antigens on the surface of red blood cells. O positive is a subtype of blood group O, and is determined by the presence of the Rh factor on the surface of the red blood cells.
Rh Factor and Blood Type O Positive
The Rh factor is a protein found on the surface of red blood cells. If you have the Rh factor, you are Rh-positive; if you don’t have the Rh factor, you are Rh-negative. About 85% of people are Rh-positive. If a person with Rh-negative blood receives blood from someone with Rh-positive blood, their immune system can produce antibodies that attack the Rh factor. This can cause serious health problems, including anemia and jaundice. Therefore, it is important for people with Rh-negative blood to receive Rh-negative blood transfusions.
Blood Transfusion Risks for Blood Type O Positive
People with O positive blood type are considered universal donors, which means they can donate their blood to people with any blood type. However, people with blood type O positive can only receive blood from other people who have blood type O positive or O negative. If a person with type O positive blood receives blood from someone with a different blood type, their immune system can produce antibodies that attack the transfused blood cells. This can cause serious health problems, including kidney failure and anaphylactic shock.
Health Risks Associated with Blood Type O Positive
While blood type O positive has several advantages, such as a lower risk of certain diseases, it also has some disadvantages. Here are some of the health risks associated with blood type O positive:
1. Heart Disease
People with blood type O positive can develop heart disease but no more than people with other blood types. According to WebMD, “people with blood type O are positive coronary heart disease risk tends to be lower. Experts aren’t sure why. Some people think it might be because other types are more likely to have higher cholesterol and higher amounts of protein associated with clotting.
2. Heartburn
People with blood type O positive are more likely to develop peptic ulcers than people with other blood types. This is because the H. pylori bacteria, which is the main cause of stomach ulcers, tends to stick to the stomach lining of people with blood type O positive. [1]
3. Blood Clotting Disorders
People with blood type O positive have blood clotting disorders, although not more than people with other blood types. Blood type O is owned by positive people Lowest average vWF: Ag level (74.8 U/dL), a protein involved in blood clotting. Having significant von Willebrand factor can increase the risk of blood clots, which can cause serious health problems such as stroke and pulmonary embolism. [2]
4. High Cholesterol
People with blood type O positive do have high cholesterol levels but as many as people with other blood types. Their bodies tend to produce LDL cholesterol, which is often referred to as “bad” cholesterol. High levels of LDL cholesterol can increase the risk of heart disease and stroke. [3]
5. Pancreatic Cancer
People with blood type O positive can develop pancreatic cancer, but the risk is higher in people with other blood types. The results showed that those with blood types A, B, or AB had a higher risk of developing pancreatic cancer than those with blood type O. The findings were published in the Journal of the National Cancer Institute. [4]
Pregnancy Complications for Women with Blood Type O Positive
Women with blood type O positive can also face some pregnancy complications. Here are some potential risks:
1. Rh incompatibility
If a woman with blood type O positive has a partner with Rh-negative blood, their child may be at risk of developing Rh incompatibility. Rh incompatibility occurs when the mother’s immune system produces antibodies that attack the Rh factor in her baby’s blood. This can cause serious health problems, including anemia and jaundice. [5]
2. Miscarriage
Women with O positive blood type may be at a higher risk of miscarriage than women with other blood types. This is because blood type O positive is associated with higher levels of the hormone FSH, which can increase the risk of miscarriage. [6]
3. Pre-eclampsia
Women with blood type O positive may be at increased risk of developing pre-eclampsia during pregnancy. Pre-eclampsia is a serious condition that can lead to complications such as premature birth and low birth weight. [7]
4. Low Birth Weight
