Living at high altitudes causes an increase in RBC counts; this is your body's response to the decreased oxygen available at these heights. Normal RBCs for males is 4.7 to 6.1 million cells per microliter, but this varies from lab to lab, and again, high altitudes will affect these values.
You will have symptoms related to high RBCs such as disturbed vision, headache, and flushing, if you are symptomatic. If you are not, your physician may choose not to treat it. Drawing blood is only temporary, as your body is going to immediately start building new red blood cells to replace the ones you drew off, so I don't recommend it. It is usually only used in an emergency basis. There are drugs that can decrease your RBCs, and your physician will determine if you need them or not.
I hope this helps! Good luck!
I don't understand where the 40-50-60.... factors in. Never heard it expressed that way. I would suggest seeing your primary care physician about this. If you got these values from a walk-in type clinic, it may be that you don't even have a problem. See your physician and be tested there. He will know if additional tests are needed, and how to treat you.
Although a high red blood cell count is not a specific disease, it may be a sign of an underlying problem. Causes can be high altitude, smoking related, right-sided heart failure, pulmonary fibrosis, polycythemia vera, kidney disease, and steroid use, to name a few. Treatment of a high red blood cell count is directed at the underlying cause. I cannot tell you how to treat it, because you do not know the cause.
I'm sorry if this wasn't the information that you desired, but the cause must be determined. You are not required to pay for any answer that you are dissatisfied with. Best of luck to you.
