What Are the Signs and Symptoms of Polycythemia Vera? Polycythemia Vera Complications. If you have PV, the thickness of your blood and the slowed blood flow can cause serious health problems. Blood clots are the most serious complication of PV. Blood clots can cause a heart attack or stroke. They also can cause your liver and spleen to enlarge.

Polycythemia Polycythemia: Introduction. Polycythemia is a rare condition in which the body produces too many red blood cells. There are two primary types of polycythemia: polycythemia vera and secondary polycythemia. The causes, symptoms, and treatments of the two conditions vary. Polycythemia vera is more serious and can lead to more critical complications than secondary polycythemia.

- Polycythemia is a condition that results in an increased level of circulating red blood cells in the bloodstream. People with polycythemia have an increase in hematocrit, hemoglobin, or red blood cell count above the normal limits.Polycythemia is normally reported in terms of increased hematocrit or hemoglobin. Primary polycythemia: In primary polycythemia the increase in red blood cells is due to inherent problems in the process of red blood cell production. 2  Secondary polycythemia: Secondary polycythemia generally occurs as a response to other factors or underlying conditions that promote red blood cell production.

- It results in polycythemia a condition which results in high levels of circulation red blood cells in the blood stream. Hypoxia, smoking, chronic exposure to carbon monoxide or living at high altitudes are its risk factors. Controlling high blood pressures, smoking etc. can potentially reduce its risk.

Cerebrovascular Accident  (Stroke) Stroke (Cerebrovascular Accident). A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes. Sudden bleeding in the brain also can cause a stroke if it damages brain cells.PubMed Health Glossary.

Polycythemia (Elevated Red Blood Cell Count) Occasionally, benign kidney cysts and kidney obstruction (hydronephrosis) can also secrete extra erythropoietin causing polycythemia. A rare genetic condition, called Chuvash polycythemia, causes increased activity of the gene that produces erythropoietin. The overproduction of erythropoietin causes polycythemia.

About polycythemia vera Polycythemia vera is a rare and incurable blood cancer associated with an overproduction of blood cells in the bone marrow that affects up to three people per 100,000 globally.1,2 This condition is part of a group of related blood cancers known as myeloproliferative neoplasms (MPNs).1 The exact causes of polycythemia vera are unknown; however, ...

Secondary Polycythemia Weakness, headaches, and fatigue are usually the first symptoms of secondary polycythemia. Patients may feel lightheaded or experience shortness of breath. Visual disturbances associated with this disorder include distorted vision, blind spots, and flashes of light.

Stroke Most strokes are caused by an abrupt. blockage of an artery (ischemic stroke). Other. strokes are caused by bleeding into brain tissue. when a blood vessel bursts (hemorrhagic stroke). The effects of a stroke depend on the severity and. which area of the brain is injured. Strokes may. cause sudden weakness, loss of sensation, or. difficulty with speaking, seeing, or walking. Since. different parts of the brain control different areas. and functions, it is usually the area immediately. surrounding the stroke that is affected. Hemorrhagic strokes have a much higher death rate.

There are two primary types of polycythemia: polycythemia vera and secondary polycythemia.The causes, symptoms, and treatments of the two conditions vary.n polycythemia, this process is abnormal due to various causes and results in too many red blood cells and sometimes other blood cells. This leads to a thickening of the blood. Polycythemia vera is caused by an abnormality of the bone marrow and is a type of myeloproliferative disorder.

Stroke Sickle-cell anemia, which can cause blood cells to clump up and block blood vessels, can also lead to stroke. A stroke is the second leading cause of death in people under 20 with sickle-cell anemia. Air pollution may also increase stroke risk.

Cerebral hypoxia TIAs cause the same symptoms associated with stroke, such as contralateral paralysis (opposite side of body from affected brain hemisphere) or sudden weakness or numbness. A TIA may cause sudden dimming or loss of vision (amaurosis fugax), aphasia, slurred speech (dysarthria) and mental confusion.

Polycythemia Polycythemia vera (PCV), polycythemia rubra vera (PRV), or erythremia, occurs when excess red blood cells are produced as a result of an abnormality of the bone marrow. Often, excess white blood cells and platelets are also produced. Polycythemia vera is classified as a myeloproliferative disease.

Secondary Polycythemia Secondary polycythemia may result from increased production of erythropoietin. This hormone, which is possibly produced and secreted by the kidneys, stimulates bone marrow production of RBCs. The increased production may be an appropriate (compensatory) physiologic response to hypoxemia, which may result from: 1  chronic obstructive pulmonary disease. 2  hemoglobin abnormalities (such as carboxyhemoglobinemia, which occurs in heavy smokers) 3  heart failure (causing a decreased ventilation­perfusion ratio)

Polycythemia Vera General Discussion. Polycythemia vera is a rare, chronic disorder involving the overproduction of blood cells in the bone marrow (myeloproliferation). The overproduction of red blood cells is most dramatic, but the production of white blood cells and platelets are also elevated in most cases.

Read the Story of a Patient Diagnosed with a Stroke Hyperperfusion, or the sudden increased blood flow through a previously blocked carotid artery and into the arteries of the brain, can cause a hemorrhagic stroke. Other complications include restenosis and short periods of medically treatable reduced blood pressure and heart rate.

- Polycythemia is a blood condition in which the bone marrow makes excess blood cells, primarily red blood cells, but also platelets and white blood cells.he extra cells cause a thickening of the blood, which increases the risk of blood clotting, in turn potentially causing strokes, heart attacks, and other complications. While the exact cause of polycythemia is not known, genetic changes are thought to be related to its development.
