High hemoglobin count may occur because:
- Your red blood cell production increases to compensate for chronically low blood oxygen levels due to poor heart or lung function.
- You have a bone marrow dysfunction that results in increased production of red blood cells.
- Your red blood cell production increases to compensate for a limited oxygen supply in higher altitudes.
- You smoke.
- You've taken drugs or hormones, most commonly erythropoietin (EPO), that stimulate red blood cell production. You're not likely to get a high hemoglobin count from EPO given to you if you have chronic kidney disease. However, EPO doping — getting injections to enhance athletic performance — can cause a high hemoglobin count.
Specific disorders or other factors that may cause high hemoglobin count include:
- Heart failure
- Kidney cancer
- Liver cancer
- Living at a high altitude, where there's less oxygen in the air
- Other types of heart disease
- Other types of lung disease
- Polycythemia vera
- Smoking, which may result in low blood oxygen levels
