Iron Deficiency Anaemia (IDA) is a disease where the human body is deprived of red blood cells and iron. A research has found that the disease is associated with hearing loss. The study was conducted by The JAMA Network on people aged between 21 and 90 years in the Unites States and its findings have shown the association.
It was found in the research that the people suffering from IDA were twice likely to suffer from hearing loss than the people who didn’t have IDA. It was found that the link was mostly for the two kinds of hearing loss – sensorineural hearing loss (SNHL) and conductive hearing loss (CHL). SNHL is when inner ear or the nerve leading from the inner ear to the brain is destroyed, while CHL is when the sound doesn’t properly reach the middle ear or the ear drum from the outer ear.
The study was conducted on 305,339 individuals in the United States from January 1, 2011, to October 1, 2015. Though, the researchers conducted the research on a large population being tested over a period of about five years, the findings show just a probable link between the two diseases.
Peter Steyger, an ENT specialist at Oregon Hearing Research Centre, said that low iron levels can interrupt working of other cells, and if it damages the hair cells in the ears, it may lead to hearing loss. The hair cells of the ear can’t be reinstated to re-establish the auditory function once they are damaged.
There are chances that treating IDA can improve the individual’s hearing. But again, this is just a probability and there is no clear evidence to confirm this claim. Further studies are required to be conducted to prove the claim.
