5-Lightheadedness
Since there is a shortage of energy, patients commonly feel lightheaded or dizzy when they suffer from anemia. This is because the oxygen supply to the brain is reduced, and this organ requires a great deal of oxygen and ATP to function correctly. Therefore, patients may have a series of neurologic symptoms starting with dizziness and fainting, especially when there are other nutritional deficits coexisting with anemia. A pale patient who fainted might not have anemia but hypoglycemia, which is a temporary alteration in blood readings. Therefore, if you find any of these symptoms in yourself or any other, you should not immediately think about anemia without getting a lab test done.
