High HB in blood
Doctor Answers (1) on High HB in blood
Some causes for high hemoglobin levels are as follows:
Living at a high altitude.
Lung disease (Emphysema, COPD).
Bone marrow disorders (polycythaemia vera).
Overdose or inappropriate use of the drug.
Blood doping (adding RBC's by IV to the bloodstream).
A high hemoglobin count is rarely an unexpected finding or simply discovered by chance. A high hemoglobin count and results from other tests may already indicate the cause of your illness.
