A recent study by the National Institutes of Health have reported that those with Diabetes are twice as likely to have hearing loss than those without the disease. The study indicated that up to 40% of those with Diabetes had hearing loss.
One of the main studies on the diabetes and hearing loss was performed in Japan by Dr. Horikawa. He states that “over time, high glucose levels can damage vessels in the stria vascularis and nerves diminishing the ability to hear”. His study was able to exclude hearing loss due to age, gender and loud noise exposure.
