<human>: I asked my doctor if my red blood cell count was low. My sister found out she was anemic and when that was treated her hair started growing in thicker, so I asked my doctor if mine was low. He said it s actually high. I didn t think to ask him what too high means. So that is my question. Is there any danger in having too many red blood cells?
<bot>: Hi, Thanks for asking. Based on your clinical history and query, my opinion is as follows:1. Yes, increased RBC's are of concern.2. Increase in RBC scan be primary-no cause known or secondary- to high altitude, hypoxia, renal tumors, myeloproliferative disorders.3. Raised RBC's increases the viscosity of blood and known to cause adverse effects like thrombosis. 4. If you are living at a high altitude then not to bother as it is a protective mechanism against decreased oxygen levels in high altitude. If not discuss with your consultant to evaluate for the possible cause of raised RBC's and manage accordingly. Hope it helps. Any further queries, happy to help again.
