Hearing loss affects approximately 34.5 million Americans, and approximately 30 million people have diabetes. These statistics make them two of the most prevalent health concerns in America. Beyond these numbers, the overlap of these populations is growing. Research continues on the potential connection between hearing loss and diabetes.
In her 2008 study from the Annals of Internal Medicine, Kathleen Bainbridge, Ph.D., an epidemiologist at the National Institute on Deafness and Other Communication Disorders, drew a number of conclusions from national survey data. She concluded that hearing loss is more than twice as common in diabetes patients than in the general population. In addition, 21% exhibited both hearing loss and diabetes, compared to 9% of those surveyed who had some form of hearing impairment but no diabetes. Finally, of the 86 million Americans with prediabetes, rates of hearing loss are 30% higher than adults with normal blood glucose levels. Perhaps, this final group is the most alarming number.
Current studies show evidence to support a noticeable overlap between the illnesses. Beyond primarily impacting older populations, medical practitioners have several theories as to how the two might be related. The current body of research linking hearing loss and diabetes is still fairly limited. So, we need more research to connect the two health concerns definitively.
Diabetes patients have sustained elevated blood glucose levels. This results in damage to many of the fine blood vessels that supply the inner ear. A network of vasculature supplies the cochlea. When patients fail to manage their illness or it goes uncontrolled for too long, it negatively impacts the the inner ear tissue and nerves. This leads to impaired hearing.
