High RBC Count

I am medical science student and doing some research work on the topic High RBC Count rates searching for details related to this topic. Will you please provide me details of High red blood cell count and also tell me what the reasons and measures for this High red blood cell count?

[Pathak]

Having a high concentration of red blood cells in the blood is called polycythaemia.

People with this condition have thicker blood, which makes it harder for blood to circulate around the body.

High red blood cell count may be caused by low oxygen levels, kidney disease or other problems.

Low oxygen levels

Your body may increase red blood cell production to compensate for any condition that results in low oxygen levels, including:

Congenital heart disease in adults
Heart failure
A condition present at birth that reduces the oxygen-carrying capacity of red blood cells (hemoglobinopathy)
High altitudes
COPD (chronic obstructive pulmonary disease) and other lung diseases
Pulmonary fibrosis
Sleep apnea
Nicotine dependence (smoking)

Performance-enhancing drugs

Certain drugs stimulate the production of red blood cells, including:

Anabolic steroids
Blood doping (transfusion)
Injections of a protein (erythropoietin) that enhances red blood cell production

Kidney Disease:

The kidneys might produce too much erythropoietin. This enhances red blood cell production.
Bone marrow overproduction

Polycythemia vera
Other myeloproliferative disorders
