Sports hematology

Q: By default, athletes are supposed to have some degree of? (select one) 

 A) anemia 
 B) polycythemia

Answer: A

Contrary to popular belief, athletes are relatively prone to be anemic when compared with the same segment of general healthy non-athlete adults, unless they are abusing performance-enhancing agents. Some of the reasons behind this paradox is increased plasma volume in athletes causing dilutional anemia, exercise-induced inflammatory cytokines, and intravascular hemolysis, popularly known as "march" hemoglobinuria. Also, athletes are at higher risk of gastrointestinal bleeding and iron deficiency anemia.
