why does anemia (iron def) cause epistaxis?

Question

i understand iron def anemia (low iron leads to low amt of hemoglobin, so the reserves are used up and then your circulating hemoglobin diminishes), but i still dont quite understand why it would cause bleeding. Is it because there is a larger gap between erythrocytes and/or hemoglobin so blood cannot clot as well, hence more bleeding?

this is due to iron deficitency, and its I dont think its common for nose bleeds, but some of the resources i've come across do mention them being associated with anemia, so i was wondering why?

Answer 1

I think it depends on the underlying reason for the anemia? Could it be a strict vegan diet, lack of vitamin B12, Folic Acid, or autoimmune condition. Depending on the reason for the anemia depends on the symptoms. I have bouts of anemia due to autoimmune condition but have never had problems bleeding? My hemoglobin was normal, but the quality poor and I had plenty of B12 and Folic Acid so the problem was my diet.
