Polycythemia (High Red Blood Cell Count) (cont.)

Relative Polycythemia

Relative polycythemia describes conditions in which red cell volume is high due to increased blood concentration of red cells as a result of dehydration. In these situations (vomiting, diarrhea, excessive sweating) the number of red blood cells is normal, but because of the fluid loss affecting the blood (plasma), red blood cell counts may seem elevated.
