Overview
Polycythemia is defined as increasing the hemoglobin (>16.5 g/dl in men or >16 g/dl in women) or hematocrit level (>49%in men or >48% in women).[1] This elevated level might be due to declining the plasma volume (relative or spurious polycythemia) or rising the number of red blood cells (true polycythemia). [2]
Causes
Life Threatening Causes
- Critical dehydration owing to fluid loss such as severe diarrhea or vomiting, which can result in Spurious Polycythemia
- Severe cyanotic heart diseases with right-to-left shunts
- End-stage cancer related to EPO-secreting tumors such as hepatocellular carcinoma, parathyroid carcinoma, pheochromocytoma, or renal cell carcinoma[3]
Common Causes
- Primary polycythemia
- Polycythemia vera and its complications
- Secondary polycythemia
- Chronic lung disease
- High altitude
- EPO-producing tumors
- High carboxyhemoglobin: mostly observed in smokers
- Kidney diseases, such as Renal cysts and renal artery stenosis,
- Iatrogenic reasons: steroids, erythropoietin treatment, anabolic testosterone replacement therapy</ref> This elevated level might be due to declining the plasma volume (relative or spurious polycythemia) or rising the number of red blood cells (true polycythemia). [2]
