Experts say research shows that many diseases have been linked to blood type. Indeed, certain blood types are more resistant to disease.
Dr. Mary Cushman, MSc, hematologist and professor at Larner College of Medicine at the University of Vermont, said that blood type AB, was more prone to stroke.
“We found that type AB was associated with stroke risk, and in general the risk of cognitive impairment. Although not all studies observe that, “Cushman said as quoted by Healthline.
“Type O, compared to other types, also protects against heart attacks and blood clots in blood vessels, known as venous thrombosis,” he added.
According to him, until now the doctors did not know the mechanism. However, he said there were differences based on blood groups in certain clotting factors, and factors in circulation related to blood vessel layer cell connections.
Add, Patricia Foster, PhD, a microbiologist and professor of biology at Indiana University, looked at the relationship between intestinal diseases such as norovirus and blood type. “Norovirus has clear biological reasons why blood types will make a difference,” he said.
“Norovirus really uses sugar on the surface of cells to attach itself to cells,” he added.
In general, people who don’t make H1 antigens and those who have type B blood tend to be resistant, whereas people with blood type A, AB, or O will tend to get sick.
“We will not know what to do about this information to prevent or treat infections,” Cushman said.
