Low iron levels cause hearing loss?

Published 9.7.2017
Low iron wasn’t the cause of my hearing loss, but iron levels in the blood has many effects. Apparently one result of low iron can be hearing loss. Too much iron is a problem too.

In the study, published Dec. 29 in the journal JAMA Otolaryngology-Head & Neck Surgery, the researchers looked at data from the medical records of more than 300,000 adults in Hershey, Pennsylvania. The participants' ages ranged from 21 to 90; the average age was 50.

Hmm… maybe it is part of my problem…

Hearing loss was divided into three categories: sensorineural hearing loss, which results from damage to the inner ear, damage to the nerve that runs from the ear to the brain, or damage to the brain; conductive hearing loss, which occurs when sound cannot travel through the ear properly; and combined hearing loss, which is a combination of the two.

The researchers found that the people with iron deficiency anemia were 2.4 times more likely to have combined hearing loss compared with those who did not have iron deficiency anemia. The people with iron deficiency anemia were also 1.8 times more likely to have sensorineural hearing loss. There was no link, however, between iron deficiency anemia and conductive hearing loss, according to the study.

Sensorineural loss results from blood vessel damage in the ear. Having an iron deficiency increase the risk of blood vessel damage.

Conductive hearing loss, on the other hand, is often caused by more "mechanical" problems, such as blockages in the ear, including those caused by earwax or fluid, or perforated eardrums. Therefore, the researchers did not hypothesize that conductive hearing loss would be linked to iron deficiency anemia, they wrote.

This research is half baked. There might be something here, there might not. Here is the full article.
