An iron deficiency can affect the body in many ways, including your ability to hear. Hearing loss develops when damage occurs to the blood vessels in the ear. The damage affects the cell’s ability to transport oxygen to vital areas, including the ears. Anemia, which is a product of iron deficiency, places people at risk for such a scenario.
Your auditory system needs a sufficient amount of iron to function properly. A deficiency of iron causes anemia, which is a lack of hemoglobin in red blood cells. The oxygen is necessary for the health of the sensory hair cells involved in translating sound into electrical impulses. When the hair cells die, they are no longer able to transmit the impulses to the brain for interpretation. This process can lead to tinnitus as well as hearing loss.
Inadequate iron intake, pregnancy, internal bleeding, endometriosis, and an inability to absorb iron can lead to an iron deficiency. The symptoms of iron deficiency appear mild at first. You may experience fatigue, weakness, shortness of breath, dizziness, tongue swelling, headaches, irregular heartbeat, and cold extremities.
Most people with anemia resulting from low iron have no symptoms. Chronic low iron, however, can cause symptoms. Anyone can develop an iron deficiency, but the condition is more common in women during childbearing years due to blood loss during menstruation. Any changes in the blood during pregnancy can also cause anemia. For older adults, blood loss is a common cause, usually due to gastrointestinal problems. Sickle cell anemia can cause hearing loss, but iron supplements are not recommended for it as it can be harmful.
For the majority of otherwise healthy people, eating a balanced diet will provide the body with an adequate supply of iron. Foods abundant in iron include red meat, pork, poultry, seafood, beans, peas, dark leafy vegetables, dried fruit, and pasta. If you are uncertain if you are getting enough iron, try the following:
