Can polycythemia be hereditary? What is the gene for too many red blood cells?

Can polycythemia be hereditary?  What is the gene for too many red blood cells?

Maybe "genetic risk: Polycythemia can be acquired. It is a natural respohse to living on a high mountain. There are oxygen censors in the brainstem and if oxidation is compromised a signal goes to the kidney to produce erythropoietin. This then signals the bone marrow to produce more red cells to compensate for the rarefied air. Exactly the same thing can happen with vitamin b1 deficiency induced by excess of sugar. ...Read more

Last blood test:high red blood cells( 5.8) high hemoglobin (17.3) high hematocrit 52% and high bilirubin 2.1. What's wrong with me? Polycythemia vera?

Hey buddy!: You've asked this question repeatedly. Being a smart teen with an interest in science, you're understandably concerned. At your age, and with normal cbc's as a kid (were they normal?) i'd be more concerned about sleep apnea -- that will ruin your life -- or that someone is giving you Anabolic steroids without your knowing it, or an erythropoietin-producing tumor somewhere. ...Read more

Red blood cells-5.9, hematocrit- 55%, hemaglobin-18.0, esr-2, ldh-199, white blood cells- 9.0 (high neutrophils) & platlets-285, 000 polycythemia vera?

Can't tell. need w/u: Normal range will vary -depending on the range used on each lab. On my lab, hb of 18 is still normal for male. Your white blood cell and platelet are also within normal range. I don't see any problem there-except you said you have high neutrophils- which can be caused by many things. However, if you are worried about p.Vera- go to see a hematologist and she/he will be able to help you. ...Read more

Hello! I've recently had a blood test done and got told while I'm not anemic I have too many red blood cells and their small. What does this mean?

Hello! I've recently had a blood test done and got told while I'm not anemic I have too many red blood cells and their small. What does this mean?

Thal minor, I bet: This is quite common and is usually caused by beta-thalassemia minor. Any competent general physician can do the workup to confirm it. If you do have thal minor, and you marry someone else who has it, the double-dose can cause you to have a child with thal major, which is horrible. Otherwise, it's a total non-problem. Best wshes. ...Read more

Could having too many red blood cells for a 5yo be a good thing?

Could having too many red blood cells for a 5yo be a good thing?

Doubt it: A healthy blood cell count implys that it is in high enough in quantity to do the work but not so high that it plugs up the system. Blood is a complex blend of cells & liquids that must flow thru our "plumbing". Too many red cels will lead to blockage, like your toilet backing up, and clogs will mean no nutrients get thru. ...Read more
