What causes a high red blood cell count

Your body may increase red blood cell production to compensate for any condition that results in low oxygen levels, including: Heart disease (such as congenital heart disease in adults) Heart failure. A condition present at birth that reduces the oxygen-carrying capacity of red blood cells (hemoglobinopathy)

What can happen if you have high red blood cells?

A high red blood cell count is a condition called polycythemia vera. If you have this medical condition, it means that your bone marrow is producing too many red blood cells. This can result in thickening of the blood, slow flow of blood, and eventually blood clots.

What cancers cause high red blood cell count?

Should I worry if my red blood cell count is high?

A high red blood cell count may be a symptom of a disease or disorder, although it doesn’t always indicate a health problem. Health or lifestyle factors can cause a high red blood cell count. Medical conditions that can cause an increase in red blood cells include: Heart failure, causing low blood oxygen levels.

Can diabetes cause high red blood cell count?

Increased diameter – Many patients with diabetes have a 10-15% increase in RBC diameter, increasing blood viscosity. This results from an influx of glucose which flattens the biconcave disk and bloats the cells.

Can stress Affect Your blood Count?

Stress levels increase white blood cell count This indicates a connection between elevated stress levels and the body’s production of what are known as inflammatory leukocytes, a particular variety of white blood cell.

Can dehydration cause high red blood cell count?

Increased red blood cell concentration Dehydration (If the liquid component of the blood (plasma) is decreased, as in dehydration, the red blood cell count increases. This is due to the red blood cells becoming more concentrated.

What blood test shows polycythemia?

How do doctors diagnose polycythemia vera (PV)? To diagnose PV, your doctor will perform a test called a complete blood count (CBC) to see if your number of red blood cells is higher than normal. Your doctor may also test your blood to look for amounts of a hormone called erythropoietin.
