Secondary polycythemia
by Alike Medical Team ∙ Updated on June 13, 2023
Secondary polycythemia refers to a rare condition which is characterized by overproduction of red blood cells. Excess red blood cells cause the thickening of the blood which increases the risk for stroke. Causes for secondary polycythemia include obstructive sleep apnea, smoking, obesity hypoventilation syndrome, chronic obstructive pulmonary disease, and some medications such as diuretics and testosterone.
