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.

What determines your blood type?

• The color of your blood

• The type of antigens on your red blood cells

• The amount of blood in your body

• The size of your red blood cells

How does type O blood affect malaria severity?

• It makes malaria symptoms more mild

• It increases the risk of severe malaria

• It has no effect on malaria

• It reduces the risk of severe malaria

Why might people with type O blood be more affected by cholera?

• They have more H antigens that cholera binds to

• They have more A and B antigens

• They have fewer red blood cells

• They have a stronger immune system

What role does the Von Willebrand factor play in heart disease?

• It prevents blood clots

• It helps blood form clots

• It increases blood pressure

• It reduces cholesterol levels

Which blood type is associated with a higher risk of heart disease?

• Type O

• Type A

• Type B

• Type AB
