Some people with polycythemia vera experience headaches, dizziness, ringing in the ears (tinnitus), impaired vision, or itchy skin. Polycythemia is treated by phlebotomy (controlled blood letting) and. Common conditions causing chronic hypoxia are chronic lung diseases such as: Abnormal blood flow to the kidneys can be perceived by the kidneys as decreased oxygenation (renal hypoxia), even though, other tissues may have normal oxygenation. 0 comment. Polycythemia is normally reported in terms of increased hematocrit (hematocrit is the ratio of the volume of red blood cells to the total volume of blood) or hemoglobin concentration (hemoglobin is a protein responsible for transporting oxygen in the blood). In secondary polycythemia, factors external to red blood cell production (for example, hypoxia, sleep apnea, certain tumors) result in polycythemia. Scientists think that it may be related to changes in certain genes. Polycythemia is a response by the body to an increased demand for oxygen. Each type has its own set of causes and risk factors. These extra cells cause the blood to be thicker than normal, increasing the risk for blood … Polycythemia refers to an elevated number of red blood cells (termed erythrocytes) in the circulation. Other causes include testosterone replacement therapy and heavy cigarette smoking. People with polycythemia are seen routinely based on the recommendation of the treating doctor. Dehydration is the excessive loss of body water. Polycythemia causes … This topic discusses the causes of polycythemia … Learn the warning signs of a heart attack and know the symptoms that may require an immediate trip to the hospital. Relative polycythaemia. Finally, there is the potential for myelofibrosis (spent marrow), in which scar tissue eventually takes over the blood-forming marrow elements, resulting in anemia from marrow failure. Heart disease, high blood pressure, diabetes, myocarditis, and cardiomyopathies are just a few potential causes of congestive heart failure. Such causes include genetic disorders, certain tumors that may secrete erythropoietin (a hormone that stimulates red blood cell production), conditions that deprive the body of oxygen such as certain lung or heart diseases. Blood tests, such as a complete blood count, will reveal any increase in red blood cells in the bloodstream, as well as any abnormal levels of platelets and white blood cells. … DM: Diabetes mellitus.

You can use this list of medical abbreviations and
Some general and non-specific polycythemia symptoms include: In patients with polycythemia vera, other blood disorders are also very common. In addition to managing symptoms, new treatments will look to help slow the progression of the disease. In 2005, genetic mutations of the JAK2 gene were found to be responsible for most cases of polycythemia vera. Polycythemia vera is typically associated with an elevated white blood cell count (leukocytosis) and platelet count (thrombocytosis).
