I don't know if I had drank too much fluid. I had been sweating heavily from exercise the day before and I regularly lose large amounts of sodium in my sweat.
If I had been drinking too much fluid could that have caused such a big difference in hemoglobin 12.6, hematocrit 39, and RBC count 4?
It is very possible I was over-hydrated at the time of the test because I felt so awful and felt better from drinking more water.
In May my hemoglobin was 14.7, RBC 5.37, hematocrit 45. This last test hemoglobin was 12.6, RBC 4, hematocrit 39.
Could over-hydration or other effects of possible heat exhaustion cause these values to lower this much?
I you were over hydrated at the time of test, that can lower the results. However, it would not be possible to determine to what degree. In case of 5-10% increase in plasma volume, the levels would fall accordingly. But the results would come back to normal in subsequent tests when the hydration is normal. So follow up tests need to be taken.
I am recovering from life threatening Anemia 8 months ago and I want to better understand by how much these fluctuations in hydration can potentially affect my blood counts so I can better interpret whether they actually worsen or improve. Or if certain changes could be attributed to hydration.
I need to drink a lot of water to stay hydrated because I lose so much from sweat during exercise. My weight regularly fluctuates by as much as 4 pounds in a day from water weight.
By how much can overhydration or dehydration affect hematocrit, hemoglobin, and RBC? I am asking for ranges. Would the recent variation be within these ranges or could they indicate that my total blood count has dropped since May?
I am about 20 pounds overweight with a very muscular build.
About 240 pounds, male, with very muscular build. About 20 pounds overweight.
