Ms. Saunders. Polycythemia Minor
Polycythemia is a disease that results in an increased level of red blood cells in the bloodstream. People with polycythemia have an increase in hematocrit, hemoglobin, or red blood cell count is more than the normal limits. Polycythemia is also known as polycythaemia or polyglobulia. Polycythemia is a disease where in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be because of an increase in the number of red blood cells. Polycythemia is sometimes called erythrocytosis because polycythemia refers to an increase in red blood cells, whereas erythrocytosis only refers to an increase of red cell mass. Polycythemia can be divided into two parts primary and secondary. Primary polycythemia is due to factors of red cell precursors. Polycythemia Vera or erythremia occurs when a lot of red blood cells are produced as a result of a problem of the bone marrow. White blood cells and platelets are also produced by polycythemia. Secondary polycythemia is caused by natural increases in the production of erythropoietin, and because of this there is an increase production of erythrocytes. In secondary polycythemia, there may be 6 to 8 million and sometimes 9 million erythrocytes per cubic millimeter of blood. Secondary polycythemia resolves when the underlying cause is treated. In Secondary polycythemia when production of erythropoietin increases it is called physiologic polycythemia. In the book Polycythemia New Insights for the Healthcare Professional Scholarly Paper it shows the Conditions which result in a physiologically appropriate polycythemia Altitude related - This physiologic polycythemia is a normal action to living. Many athletes train at high altitude to take advantage of this effect on blood doping. People believe athletes with primary polycythemia may have a
