Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Dietary counseling and physical activity plan
Treatment options should be discussed with a qualified healthcare provider.
Therapeutic Phlebotomy
Periodic removal of blood to reduce red blood cell mass and decrease blood viscosity, helping to prevent thrombotic complications associated with elevated hematocrit levels.
Low-Dose Aspirin Therapy
Low-dose aspirin may be prescribed to reduce platelet aggregation and lower the risk of blood clots, which are elevated in erythrocytosis patients.
Additional treatment options
Regular Hematologic Monitoring
Scheduled blood tests to monitor hemoglobin, hematocrit, and erythropoietin levels to guide treatment intensity and frequency of phlebotomy sessions.
monitoringOptimized Hydration Management
Maintaining adequate fluid intake to help manage blood viscosity and support overall circulatory health, particularly important during exercise or hot weather.
lifestyleIron Restriction
Avoiding iron supplements and limiting iron-rich foods to prevent iron overload which can exacerbate erythrocytosis by promoting additional red blood cell production.
