There is now strong evidence that people with certain blood types can have a higher or lower risk of some diseases.
WHAT CAN YOUR BLOOD TYPE SAY ABOUT YOUR HEALTH?
Type AB, A, and B
According to research from the Harvard School of Public Health, people with blood type O are less at risk for heart disease.
At Risk: Type AB
A recent study found people with type AB blood were 82 percent more likely to experience difficulties with memory recall, language, and attention than people with other types.
At Risk: Type O
Multiple studies have found a correlation between a woman’s blood type and the reproductive system. One study by researchers at Yale University and New York’s Albert Einstein College of Medicine found that women with blood type O are twice as likely to have a lower egg count and poorer egg quality than others.
At Risk: Type AB
In a recent study conducted in Denmark, researchers found that people with type AB had a 4 percent higher risk of DVT (deep vein thrombosis) than people with type O.
At Risk: Type A
Several studies have found that that people with blood type A have a higher risk of gastric cancer, says investigator Gustaf Edgren, M.D., Ph.D., associate professor of epidemiology at the Karolinska Institute in Sweden.
At Risk: Type A and O
Your blood type antigens determine how much of the stress hormone cortisol is released. People with blood type A naturally release higher levels of cortisol and also produce more in response to stressful situations than other blood types.
People with blood type O may produce less cortisol than type A, but they are prone to overproducing adrenaline during times of stress, creating a “fight or flight” reaction. This makes it more difficult for type O’s to clear the cortisol from their system.
