Anemia can lead to tinnitus. The occurrence of tinnitus due to anemia often indicates that the anemia is severe. At this time, transfusion of red blood cells as supportive treatment, and correcting the anemia afterwards, will make the tinnitus disappear. The reason anemia causes tinnitus is that it leads to a state of ischemia and hypoxia in various organs of the body. In the auditory system, this is manifested as tinnitus; in the nervous system, it is also manifested as dizziness, headache, a feeling of heaviness in the head, and even cerebral infarction; in the cardiovascular system, it is manifested as palpitations and panic.
