A patient with FEV1/FVC decreased ratio, polycythemia on CBC, and a history of smoking, most likely has what disorder?

COPD ## Footnote COPD is associated with polycythemia because the chronic lung damage in COPD leads to chronic hypoxia (low oxygen levels), which triggers the body to produce more red blood cells in an attempt to compensate by increasing oxygen carrying capacity, resulting in a condition called secondary polycythemia; this response is driven by the hormone erythropoietin, released by the kidneys in response to low oxygen levels.
