High Red Blood Cell Count: Signs to Watch For and What Helps

Q: How is a high red blood cell count diagnosed?

Diagnosis typically involves a complete blood count (CBC) test, which measures the number of red blood cells in the blood. Additional tests may be conducted to determine the underlying cause, such as measuring oxygen levels, testing for erythropoietin levels, or genetic testing.

Q: Is a high red blood cell count always a cause for concern?

Not always. Sometimes, a slightly elevated RBC count may be a normal response to certain conditions, such as living at high altitudes or engaging in intense physical training. However, a healthcare provider should evaluate significantly high levels to rule out serious conditions.

Q: How does dehydration affect red blood cell count?

Dehydration can lead to a relative increase in red blood cell count because the volume of plasma (the liquid part of blood) decreases, making the concentration of RBCs appear higher. Rehydrating can often normalize the RBC count in these cases.

Q: What lifestyle changes can help manage a high red blood cell count?

Lifestyle changes that may help include staying hydrated, quitting smoking, managing chronic conditions, maintaining a healthy weight, and regular exercise. Additionally, avoiding performance-enhancing drugs like EPO can prevent artificially high RBC counts.
