Can blood donation cause any harm to the donor? I have been told so, but cannot find any references supporting this claim. I have also learned that our body will replace the lost fluids within 24 hours and the RBCs within weeks. Can blood donation still cause health issues for our body?
This is not a personal medication question, and I mainly want to know how the body responds to blood loss and what mechanisms that monitor the altered levels of blood volume? To me, it would also be unethical by medical doctors to withhold the possible risks of blood donation to prospective donors, but it might also be seen as unethical to discourage a person willing to donate blood from doing so, so there might be a conflict of interest here.
