What is the combining form erythrocytosis?

The combining form "erythrocytosis" refers to an increase in the number of red blood cells (erythrocytes) in the bloodstream. The prefix "erythro-" denotes red, while the suffix "-cytosis" indicates an increase in cells. This condition can result from various factors, including chronic hypoxia, certain tumors, or polycythemia vera. Erythrocytosis can lead to increased blood viscosity and may pose health risks if not managed properly.
