Thanks for your questions. I recommend that you discuss your concern with your doctor
. To answer your first question first, there are some situations in which an elevated level of red blood cells (RBCs) can be very beneficial before surgery
. Some examples include surgery in which it is expected that there will be a large amount of blood loss. These red blood cells can also be beneficial as they help to deliver oxygen and nutrients to the muscles of your body, specifically your heart, and so there are some surgeons
who feel that the risk of peri operative heart problems may be reduced by having more red blood cells. On the other hand, if the levels are too high, it can lead to an increased risk of blood clots in the legs, which can then result in these clots being sent up through the blood stream and their lodging in the lungs, which can be life threatening. Depending on the type and length of surgery that you are planning, this may affect your risk as well. Overall, the lifestyle that you describe appears to be quite healthy and should help to improve your quality of life and decrease your risks near the time of surgery. Please speak with your doctor about this question.
