Can iron deficiency anemia cause hypotension and olfactory hallucinations?

Iron deficiency anemia can definitely cause hypotension if the anemia is severe enough. Taking iron supplement with vitamin C (about 500mg) helps to absorb the iron better. I have not encountered olfactory hallucinations with either iron deficiency anemia or the treatment. But, you also need to find out why you have iron deficiency anemia-perhaps this will lead to the cause of the hallucinations .
