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.


What is a increase in red blood cells called?

An increase in red blood cells is called erythrocytosis. This condition can occur due to various factors, including chronic hypoxia, certain tumors, or as a response to dehydration. Erythrocytosis can lead to increased blood viscosity, which may cause complications such as hypertension or thrombosis. It's important to identify the underlying cause for appropriate management.


What is the definition of secondary polycythemia?

Secondary polycythemia is an acquired form of a rare disorder characterized by an abnormal increase in the number of mature red cells in the blood. Secondary polycythemia is also called secondary erythrocytosis.


What is secondary erythrocytosis in a dog?

Break this down into two parts. Erythrocytosis means an elevated red blood cell count. Secondary means that it is due to other causes than "first" or usually considered, or that develops due to some other "primary" cause. For example, when you get a cold, a virus is the primary infection, and antibiotics are not useful. Some people, however, due to a poor immune system or other complicating factors, also contract a bacterial infection (Strep throat, or a sinus infection), and this would be a secondary infection. Secondary erythrocytosis is an elevated red blood cell count NOT due to a "primary" bone marrow disease called polycythemia vera. (Polycythemia means a high cell count, usually red blood cells.) Therefore, there are several causes of secondary erythrocytosis, and there would be multiple tests necessary to determine the specific cause. Leading possibilities would be any condition that lowers the oxygen levels in the blood stream (lung or heart disease, pneumonia, heartworm infection) and several tumor or cancer conditions.


A condition in which the hematocrit is elevated and the blood volume is normal would be?

Polycythemia often is used to describe an increase in the number of RBC's with no reference to the influctuations in leukocytesand platlets. However, this condition is more accurately termed erythrocytosis.


WHAT is the medical term meaning condition characterized by overproduction of erythrocytes?

Polycythemia is the medical term that refers to a condition characterized by the overproduction of erythrocytes (red blood cells). This can lead to an increase in the number of red blood cells circulating in the blood, which can affect blood viscosity and flow.

What might cause the body to create more blood cells?

Causes of a raised red cell countAbsolute erythrocytosis may be caused by an abnormality within the red blood cells (primary erythrocytosis) or by another condition (secondary erythrocytosis). A raised red cell count most often develops from another disease. Usually, this is because a problem outside of the bone marrow stimulates the production of red blood cells. These diseases can be split into two main groups: * those that cause low oxygen levels in the blood, for example from blockage to a kidney artery or lung disease. * those that cause enhanced erythropoietin production, for example because of a tumour. Erythropoietin is the hormone that regulates the production of red blood cells. Less often it occurs due to an abnormality of the red cells in the bone marrow itself, otherwise known as polycythaemia rubra vera (PV). Genes and raised red cell count It is rare for a person to inherit an erythrocytosis - either as a problem within the red cells themselves or one of the conditions that causes it. Congenital red cell disorders are caused by a mutation in: * the erythropoietin cell receptor that stimulates the synthesis of red cells * the von Hippel Lindau protein that affects the production of erythropoietin * proline dehydroxylase enzymes that also affect the quantity of erythropoietin. Other inherited disorders include: * a type of haemoglobin that binds more tightly to oxygen; a lower concentration of a compound called 2,3 diphosphoglycerate (2,3,DPG). In both, less oxygen is delivered to the tissues of the body. The body then compensates by increasing the total quantity of haemoglobin and thus red cells. * a higher-than-normal level of erythropoietin.


What if RBC 20-40 H?

If RBC (red blood cell) count is between 20-40 H (high), it typically indicates a condition called erythrocytosis, which can result from factors such as dehydration, living at high altitudes, or certain medical conditions. Elevated RBC levels may lead to increased blood viscosity, raising the risk of complications like thrombosis. It's essential to consult a healthcare professional for further evaluation and appropriate management.
