Physiological

This disease belongs to the Leukemia and usually accompanied by a proliferation of other germs blood, resulting in an increase in the blood is found not only erythrocytes, but an increase in white blood cells and platelets, leading to leukocytosis and thrombocytosis. 2. Secondary polycythemia in turn are divided into: Physiological absolute polycythemia. It is based on physiologically due to the increase in red blood cells (hemoglobin) during prolonged hypoxia, which is associated with the need to increase the supply of oxygen to the body. Physiological secondary absolute erythrocytosis developing chronic obstructive pulmonary disease, altitude sickness, congenital 'blue' heart defects, karboksigemoglobinemii (the hard-core smokers), hemoglobinopathies with increased affinity of hemoglobin for oxygen deficit of 2,3-diphosphoglycerate in . secondary polycythemia absolute. It is developed for diseases that are directly or indirectly lead to abnormal excessive stimulation cerebellar hemangioblastoma, hepatoma, cancer and cerebral cortical layers of the adrenal, pituitary adenomas and cysts, maskuliniziruyuschie ovarian tumors, renal cysts, hydronephrosis, nephrotic syndrome, chronic hemodialysis, blood at a given relative polycythemia, so their total number does not change, and increasing the ratio of red blood cells to blood volume due to haemoconcentration, ie increased hematocrit levels. This polycythemia occurs when dehydration, such as vomiting, diarrhea, sweating, excessive taking diuretics, burn patients, shocked..
