High Red Blood Cell Count

A high red blood cell count, also known as erythrocytosis or polycythemia, is a condition where the body produces too many red blood cells. This can lead to an increased risk of blood clots and other complications.

Causes

• Primary polycythemia: A rare disorder in which the bone marrow overproduces red blood cells due to a genetic mutation.
• Secondary polycythemia: Caused by external factors such as:
  • High altitude
  • Chronic lung disease
  • Heart disease
  • Kidney tumors or cysts
  • Testosterone replacement therapy
• Relative polycythemia: Caused by a decrease in plasma volume, which can occur due to:
  • Dehydration
  • Blood loss
  • Diuretic use

Symptoms

Symptoms of a high red blood cell count may include:

• Headaches
• Dizziness or lightheadedness
• Itching or tingling sensations
• Redness or warmth of the skin
• Fatigue or weakness
• Shortness of breath

Diagnosis

Diagnosis is typically made through a combination of:

• Complete blood count (CBC): To measure the number of red blood cells, white blood cells, and platelets in the blood.
• Blood smear: To examine the shape and size of red blood cells.
• Genetic testing: To identify genetic mutations that may be contributing to the condition.
• Imaging tests: Such as ultrasound or CT scans, to rule out underlying conditions such as kidney tumors or cysts.

Treatment

Treatment for a high red blood cell count depends on the underlying cause and may include:

• Phlebotomy: Regular removal of blood to reduce the number of red blood cells.
• Medications: To reduce the production of red blood cells or prevent blood clots.
• Oxygen therapy: To increase oxygen levels in the blood.
• Treatment of underlying conditions: Such as chronic lung disease or heart disease.

Complications

If left untreated, a high red blood cell count can lead to complications such as:

• Blood clots
• Stroke
• Heart attack
• Kidney damage
• Liver damage
