Quick Answer: What Causes High RBC?

What is normal RBC count?

A normal RBC count would be: men – 4.7 to 6.1 million cells per microlitre (cells/mcL) women – 4.2 to 5.4 million cells/mcL..

What happens if RBC and WBC are high?

If your white blood cell count is higher than normal, you may have an infection or inflammation. Or, it could indicate that you have an immune system disorder or a bone marrow disease. A high white blood cell count can also be a reaction to medication.

Why is my red blood cell count high?

Medical conditions that can cause an increase in red blood cells include: Heart failure, causing low blood oxygen levels. Congenital heart disease (born with it) Polycythemia vera (a blood disorder in which the bone marrow produces too many red blood cells)

What happens if you have too many red blood cells?

Polycythemia vera (pol-e-sy-THEE-me-uh VEER-uh) is a type of blood cancer. It causes your bone marrow to make too many red blood cells. These excess cells thicken your blood, slowing its flow, which may cause serious problems, such as blood clots. Polycythemia vera is rare.

Can polycythemia go away?

There’s no cure for polycythemia vera. Treatment focuses on reducing your risk of complications. These treatments may also ease your symptoms.

Can dehydration cause high RBC count?

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. The actual number of red blood cells stays the same.)

Should I worry if my hemoglobin is high?

High hemoglobin levels could be indicative of the rare blood disease, polycythemia. It causes the body to make too many red blood cells, causing the blood to be thicker than usual. This can lead to clots, heart attacks, and strokes. It is a serious lifelong condition that can be fatal if it is not treated.

What are the symptoms of high hemoglobin?

Common symptoms of high Hgb levels include:itchiness.headache.dizziness.getting easily bruised or bleeding.sweating more than usual.painful joint swelling.abnormal weight loss.a yellow tint to the eyes and skin (jaundice)More items…

How do you treat high red blood cell count?

How is a high red blood cell count treated? If a medical condition is causing a high red blood cell count, your doctor may recommend a procedure or medication to lower it. In a procedure called a phlebotomy, a health professional inserts a needle into your vein and drains blood through a tube into a bag or container.

How high is too high RBC?

A high red blood cell count is generally considered to be anything above 6.1 million red blood cells for men, 5.4 million for women, and 5.5 for children.

Can high red blood cell count cause high blood pressure?

The overproduction of red blood cells and high hematocrit levels associated with polycythemia vera can contribute to systemic hypertension; high hematocrit levels have been found to interfere with the vasodilatory effects of nitric oxide.

What should I eat if my red blood cells are high?

5 nutrients that increase red blood cell countsred meat, such as beef.organ meat, such as kidney and liver.dark, leafy, green vegetables, such as spinach and kale.dried fruits, such as prunes and raisins.beans.legumes.egg yolks.

What causes elevated red blood cells and hemoglobin?

Medical conditions that can cause high hemoglobin levels include: Polycythemia vera (the bone marrow produces too many red blood cells) Lung diseases such as COPD, emphysema or pulmonary fibrosis (lung tissue becomes scarred) Heart disease, especially congenital heart disease (the baby is born with it)

Is high RBC count bad?

Potential complications of polycythemia vera are increased levels of circulating red blood cells, which increase the thickness or viscosity of the blood. This can be associated with higher risk of thrombus or clot formation leading to strokes, heart attacks, pulmonary embolism, and possibly death.

Can exercise lower red blood cell count?

Despite stimulated erythropoiesis, exercise can decrease the red blood cell mass by intravascular hemolysis mainly of senescent red blood cells, which is caused by mechanical rupture when red blood cells pass through capillaries in contracting muscles, and by compression of red cells e.g., in foot soles during running …

What does high blood count mean?

By Mayo Clinic Staff. A high white blood cell count usually indicates: An increased production of white blood cells to fight an infection. A reaction to a drug that increases white blood cell production. A disease of bone marrow, causing abnormally high production of white blood cells.

Can thyroid problems cause high red blood cell count?

Patients with hypothyroidism have a decreased erythrocyte mass due to reduction of plasma volume and may undetectable by routine measurement such as hemoglobin concentration, whereas an increased erythrocyte mass is observed in most hyperthyroid patients (11-12) .

Does sleep apnea cause high red blood cell count?

As obstructive sleep apnea (OSA) can be a possible cause of elevated red blood cell count, Ojile says primary care physicians should consider referring these patients for evaluation for OSA. A simple blood test administered by physicians can measure complete blood count.
