Type O: Lower risk of blood clots
Considering that type Os have lower quantities of the proteins that help blood coagulate, they’re also less likely to suffer from blood clots. (The downside is that blood clotting helps prevent excessive bleeding.) That said, there are many things that cause blood clots.
“It shouldn’t be assumed that being an O blood type means an individual is ‘protected’ or an A blood type is at higher risk,” says American Society of Hematology Councilor Terry B. Gernsheimer, MD.
