    Excessive erythrocytosis (EE) is a maladaptive response to chronic high-altitude hypoxia, linked to high-altitude polycythemia and chronic mountain sickness.

  • 2

    Emerging studies indicate a potential association between erythrocytosis burden and systemic hypertension at high altitude, particularly in Tibetan populations.

  • 3

    The relationship between EE and hypertension remains unclear, with evidence supporting association more strongly than causation.

  • 4

    High-altitude hypertension is influenced by factors such as chronic hypobaric hypoxia, population-specific adaptations, and renal-neurohumoral responses.

  • 5

    Current research highlights the need for longitudinal studies to clarify the role of erythrocytosis in high-altitude hypertension and related phenotypes.
