Short answer: Yes, diabetes can cause hearing loss, and it does so more often than most people realize. A comprehensive review published in November 2025 found that people with type 2 diabetes face more than four times the risk of hearing loss compared to those without it. The connection involves the same blood vessel and nerve damage that drives other diabetes complications, but it happens in a part of the body most patients and providers aren't routinely checking.
For a long time, the link between diabetes and hearing loss was discussed in clinical circles but not well understood by patients or their physicians. That has started to change.
In November 2025, the American Academy of Otolaryngology–Head and Neck Surgery published a rigorous systematic review and meta-analysis in its peer-reviewed journal, Otolaryngology–Head and Neck Surgery. Researchers analyzed data from 17 studies encompassing nearly 8,000 participants — people with type 2 diabetes and matched controls without it. The findings were striking: hearing loss was present in 41% to 72% of people with diabetes, and the overall risk was more than four times higher than in people without the condition.
The CDC has noted for some time that hearing loss is twice as common in people with diabetes as in people of the same age without it, and that even prediabetes raises the risk by about 30%. The 2025 analysis, drawing on more recent and comprehensive data, suggests the association may be stronger than previously appreciated.
This is not a fringe finding or a minor correlation. It is a consistent pattern across a substantial body of research, and it has real implications for the tens of millions of Americans living with diabetes.
To understand the connection, it helps to know a little about how hearing works at the cellular level.
The inner ear, or cochlea, is densely supplied with tiny blood vessels and nerve fibers. These structures are responsible for converting sound vibrations into the electrical signals your brain interprets as speech, music, and the sounds of everyday life. They are also extraordinarily sensitive to changes in blood supply and oxygen delivery.
Diabetes damages blood vessels throughout the body over time. This is the same mechanism behind diabetic retinopathy in the eyes, nephropathy in the kidneys, and neuropathy in the feet and hands. The inner ear is not exempt from this process. When blood vessels feeding the cochlea are narrowed or damaged by chronically elevated glucose, the hair cells responsible for detecting sound begin to lose function. Those changes tend to be gradual and are often painless, which is part of why they go unnoticed for so long.
Diabetes also affects the auditory nerve itself. Research suggests that elevated blood sugar can impair the nerve pathways that carry sound signals from the cochlea to the brain, compounding the effect of any structural damage to the inner ear.
The result is a form of hearing loss that is sensorineural in nature, meaning it originates in the inner ear or auditory nerve rather than the middle ear. This type of hearing loss is not reversible, but it is manageable when identified early.
The hearing loss associated with diabetes tends to follow a familiar pattern: it affects high-frequency sounds first. These are the sounds most responsible for speech clarity: consonants like s, f, th, sh, and k. Vowels, which are lower in frequency, are often preserved longer, which creates a particular kind of confusion.
People experiencing this kind of hearing loss frequently say things like:
These are not signs of inattention or aging in isolation. They are consistent symptoms of high-frequency hearing loss, and they deserve clinical evaluation. If you have diabetes and recognize yourself in any of these descriptions, that recognition matters.
The short answer is yes, and the relationship is meaningful.
The 2025 meta-analysis found that people with less well-controlled diabetes — reflected in higher hemoglobin A1c levels — were more likely to have moderate to profound hearing loss. Diabetes duration also emerged as a significant factor: living with diabetes for 10 or more years roughly doubled the risk of hearing loss compared to shorter durations.
This does not mean that everyone with diabetes will lose their hearing, or that those with longer disease duration are without recourse. It means that managing blood sugar is protective not just for your heart, kidneys, and eyes, but for your ears as well. And it means that the longer diabetes goes uncontrolled, the more attention hearing health deserves.
For patients already doing the work of managing their diabetes carefully, this is reinforcing information. For patients whose control has been inconsistent, it is one more concrete reason to take it seriously.
If you have diabetes and have never had a formal hearing evaluation, the most useful thing you can do is get a baseline.
A comprehensive hearing evaluation at an audiology practice is not painful, takes about an hour, and gives you and your care team a clear picture of where your hearing stands today. That baseline matters because hearing loss is gradual — having an established starting point makes it much easier to detect changes over time and respond to them early.
When you come in for your evaluation, let your audiologist know you have diabetes. That context shapes how we interpret your results and what we look for. Hearing loss associated with diabetes has specific characteristics on an audiogram, and understanding your full health picture helps us give you the most accurate assessment and the most relevant guidance.
Hearing care doesn't need to exist in a separate silo from the rest of your health. The same way you schedule regular eye exams and foot checks as part of diabetes management, a hearing evaluation belongs in that picture too.
If you have questions about what a hearing evaluation involves or whether it is right for you, we are glad to help you figure that out — without pressure and without obligation. That is exactly the kind of conversation we have every day at Live Better Hearing + Balance.
