A week ago on Monday I had blood work done and results showed a Hematocrit of 56% (five weeks into cycle). I had not drunk enough water before the lab work. Doctor ordered immediate therapeutic blood withdrawal. I hydrated well this weekend and before the blood was withdrawn, Hematocrit was 53%, a 3% drop by drinking water alone. The point is that if you stay hydrated, chances are that you won’t be having issues with high hematocrit. Drink lots of water!!!
