<s>[INST] Im recently undergoing investigation into a high red blood cell count from a couple of blood tests (one fasted, one not but with directions to increase water intake) I m 31, for healthy and I lift weights. I also recently took a sleep apnea test kit home, however it failed and I have to repeat it (nasal attachment fell out). In the meantime, I m worried I ve been reading up about so many negative effects of this such as too much iron in the diet (which I have no idea how much is in I know I can t possibly be deficient in it I eat veggies and spinach and foods high in protein every day, including a vegan protein powder), and can lead to blood clots?? Should I be this concerned?? Is there anything I can do to reduce red blood cells myself? Drink more water, exercise less? Thanks any advice would be appreciated. [/INST] Thanks for putting up your query here. But before I give you any advice I would like to see your blood reports (complete blood count). Increased RBC count is known as Polycythemia in medical terms. There are various reasons for polycythemia, ranging from a very benign condition to a malignant condition. It would be not possible to comment on it without having a look into your CBC report. Please scan and send it. Thank you. </s>
