How Your Blood Type Protects and Hurts You

The video explains how blood types, determined by specific antigens on red blood cells, influence susceptibility to diseases like malaria, cholera, and heart disease. Type O blood offers some protection against malaria but increases vulnerability to cholera. Conversely, A and B antigens may reduce cholera risk but are linked to higher heart disease rates due to their effect on Von Willebrand factor. While blood type plays a role in disease risk, lifestyle factors are more significant. Ongoing research aims to understand these relationships better to improve health outcomes.
