There is a link between specific blood groups and 49 diseases. The discovery was made in a medical study in Sweden. The Karolinska Institute study analyzed data from more than 5 million people and more than 1,000 diseases.
Research has shown that certain blood groups are associated with an increased risk of blood clots, circulatory problems, or high blood pressure during pregnancy. The basic elements in human blood are the same, but some different things divide it into 4 blood groups.
What sets these four blood groups apart is their antigens, proteins, or carbohydrates that enter the bloodstream to accelerate the production of antibodies.
Previous research reports have found that people with O-blood group have a lower risk of coronary heart disease or blood clots, but are more likely to bleed than people with A or B group.
The study, published in the Medical Journal eLife, analyzed data from more than 5 million people from the Swedish Health Registry and found that 49 diseases belonged to blood groups.
Research has shown that people with A blood group have a higher risk of blood clots, while people with O blood group have a higher risk of hemorrhagic diseases, while women with O blood group may have a higher risk of high blood pressure during pregnancy.
Research has shown that people with B blood groups have a lower risk of kidney stones. The researchers said that more research is needed to confirm the findings to determine if there is an increased risk of certain diseases from different blood groups or to explain the possible association.
Researchers also said the findings point to a new and interesting link between disease and blood groups while paving the way for future research reports. Future research will need to identify mechanisms that can explain this relationship.
