Your blood type does more than determine compatibility for transfusions. Research suggests it may also influence certain health risks, though it is only one factor among many.

Heart health is one area of interest. People with type O blood may have a lower risk of coronary heart disease, possibly due to lower cholesterol levels and reduced clotting tendencies.

Cancer risk may also vary. Studies indicate that types A, B, and AB could have a higher risk of stomach and pancreatic cancers, potentially linked to infections like H. pylori.

Some research has explored memory and cognition. One study found that individuals with type AB blood may be more prone to memory issues, though this finding requires further investigation.
