What causes a high red blood cell count?
What does it mean when your red blood cells are high?
There are many disorders that cause elevated red blood cell (RBC) counts. RBCs are made in your bone marrow. A hormone called erythropoietin, made by the kidney, stimulates the production of them. So, here is a list of many of the conditions that can increase RBCs:
1) Heart diseases, like CHF (congestive heart failure)
2) Lung diseases (like COPD or Pulmonary fibrosis)
3) Medications, like Procrit (erythropoietin) or anabolic steriods (testosterone)
5) Kidney diseases (like cancer)
6) Living at increased altitudes
7) Blood disorders, like polycythemia vera
Your health care provider should be able to help you try to figure out why this is happening to you. If they cannot help you, try to see a hematologist for help. Good luck!
