High hemoglobin count occurs because your red blood cell production increases to compensate for chronically low blood oxygen levels due to poor heart or lung function. If you have a bone marrow dysfunction that results in increased production of red blood cells.
High hemoglobin count include:
COPD (chronic obstructive pulmonary disease)
Heart failure, Kidney cancer
, Liver cancer
Living at a high altitude, where there's less oxygen in the air
Other types of heart disease and lung disease, Polycythemia vera
Smoking, which may result in low blood oxygen levels
we need to rule out the above causes first, so do consult us.
