I was diagnosed with Polycythemia Vera in 2010. My red blood cells were at 1 million and normal is 200,000 to 400,000. My cancer doctor started giving me phlebotomys and hydroxyurea. The lowest my red cell count ever got to was 800,000. Two years ago I looked up foods that thin your blood and started eating them. I was visiting my dad at the time and went to his doctor after two weeks being on this diet. He did a blood test and my count was 300,000!!! He asked if I was sure about being diagnosed with PV and I told him I had a bone marrow biopsy and was positive. He couldn't believe it.
If you want, just look up foods on the internet that thin your blood and avoid the ones that thicken your blood. I no longer take hydroxyurea or get phlebotomys and am normal!!
