The Overlooked Link between Hearing and the Endocrine System


Hearing depends on more than just the ears—it relies on proper circulation, nerve health, and metabolic balance. Conditions such as diabetes and thyroid disorders can disrupt these systems, potentially impacting auditory function.

Emerging research suggests that metabolic and hormonal changes may contribute to hearing loss, highlighting the importance of early identification and comprehensive care.


At Johnson Audiology, we consider hearing care an important component of comprehensive patient management. Early identification and intervention can help detect hearing changes, support communication, and improve overall patient outcome.

What is the relationship between diabetes and hearing?

Hearing loss is twice as common in people with diabetes. Even adults with elevated blood sugar—without a formal diabetes diagnosis—are 30% more likely to have hearing loss than those with normal glucose levels. High blood sugar damages small blood vessels and nerves in the inner ear, while low blood sugar over time can interfere with how signals travel from the ear to the brain. Both forms of damage can result in hearing loss.

How do metabolic changes affect the cochlea?

Metabolic changes can significantly affect the cochlea, the inner ear structure responsible for hearing. Conditions such as diabetes, obesity, and mitochondrial dysfunction may reduce blood flow, increase oxidative stress, and damage delicate cochlear hair cells. Recent research has identified a “liver–inner ear axis,” showing that metabolic inflammation can weaken cochlear structures and delay recovery from noise exposure. Studies also reveal that altered cellular metabolism and mitochondrial damage contribute to age-related and noise-induced hearing loss, highlighting metabolism as an important target for future hearing therapies.

How do thyroid disorders impact auditory function?

Thyroid disorders can negatively impact auditory function by affecting the nerves, blood flow, and metabolic processes involved in hearing. Hypothyroidism has been linked to sensorineural hearing loss, tinnitus, and balance issues due to slowed nerve conduction and reduced oxygen delivery to the cochlea. Hyperthyroidism may also contribute to hearing fluctuations and sound sensitivity. Current research suggests thyroid hormone imbalances can alter inner ear development and function, making early diagnosis and proper medical management important for protecting long-term hearing health and communication ability.

Can hormone imbalances from the pituitary impact the auditory system?

Yes, hormone imbalances related to the pituitary gland can impact the auditory system. The pituitary regulates hormones that influence metabolism, circulation, inflammation, and nerve function—all essential for healthy hearing. Disorders involving growth hormone, cortisol, or thyroid-stimulating hormone may contribute to hearing loss, tinnitus, dizziness, or balance problems. Research suggests hormonal disruptions can affect blood flow to the cochlea and alter auditory nerve signaling. Because the endocrine and auditory systems are closely connected, treating underlying hormonal conditions may help support hearing and overall ear health.

Is there a link between osteoporosis and hearing loss?

Research suggests there may be a connection between osteoporosis and hearing loss. Osteoporosis weakens bones throughout the body, including the tiny bones and structures within the ear that help transmit sound. Reduced bone density may also affect blood supply to the cochlea, potentially contributing to sensorineural hearing loss. Studies have found that individuals with osteoporosis, especially older women, may have a higher risk of hearing decline. Current research continues to explore how calcium metabolism, bone health, and inner ear function are interconnected and how early intervention may help protect hearing.

Does treating hearing loss improve patient outcomes?

Early identification of hearing loss can greatly improve patient outcomes by allowing treatment and support to begin before communication difficulties become more severe. Detecting hearing changes early may help patients stay socially connected, maintain independence, and reduce the risk of frustration, isolation, and cognitive decline associated with untreated hearing loss. For individuals managing other health conditions, including endocrine disorders, early hearing care can also improve communication with healthcare providers and loved ones. Treatment options such as hearing aids, assistive listening devices, and counseling are often more effective when hearing loss is addressed promptly. Regular hearing evaluations play an important role in protecting long-term hearing health and quality of life.

For years, Johnson Audiology patient Kim Haney lived with a constant sound that no one else could hear. What began in her mid-30s as relentless tinnitus eventually became hearing loss that affected nearly every aspect of her daily life—from conversations with loved ones to simple interactions in restaurants. "The tinnitus was like being locked in a room with 10,000 crickets and not being able to escape," Kim recalls. "It was 24 hours a day, seven days a week. It affects your concentration. It affects your ability to hear what's going on around you without focusing in on the crickets." Her husband, Jim, witnessed the changes long before he understood what was causing them. "She would become agitated, and I didn't know what it was," he says. "After doing a little research, I realized the tinnitus was really the root of her agitation." As Kim's hearing declined, he found himself translating conversations, repeating what restaurant servers had said, and filling in the gaps she couldn't hear. "I was tired of translating," he laughs. "So I said, 'You're going to see an audiologist.'" That decision changed everything. Kim still remembers the emotions of her first appointment with Dr. Megan Johnson, founder and owner of Johnson Audiology. "When Dr. Johnson held up a notecard in front of her mouth during my hearing test appointment, I just burst into tears," she says. "When I didn’t have the visual cue of reading her lips, that's when I realized how much I had been missing." Now, after years of hearing care and advancements in technology, Kim says the difference is remarkable. "The technology has jumped in leaps and bounds," she says. "It's incredible how much it continues to evolve." One of the most meaningful moments came when Jim surprised her with new hearing aids as a Christmas gift. "I was expecting one of his paintings. He’s a wonderful artist, and I wanted a piece of his artwork for my office at work," Kim says with a smile. "Instead, I unrolled the package to find a handmade certificate he had created elling me I was getting new hearing aids. I started crying. It was such a thoughtful gift." Jim has no regrets about his unconventional present. "Instead of rings and watches," he says, "I gave her hearing aids." Kim agrees without hesitation. "I’ll take hearing aids over jewelry any day."  Today, after more than two decades together, the Haneys know that better hearing is about far more than hearing sounds. It's about understanding conversations, sharing experiences, and fully enjoying life. For Kim, seeking treatment didn't just improve her hearing—it gave her back the moments that matter most. In fact, she used her new hearing aids recently at a rock concert for the first time. “My friend and I had so much fun! It was amazing!” Kim says.

From clearer conversations to smartphone connectivity, your hearing aids may be capable of more than you realize. Imagine sitting at a crowded dinner table, surrounded by friends and family. You can hear people talking, but following the conversation is another story. Voices overlap, background noise competes for your attention, and you find yourself smiling along even when you've missed a few words. Now imagine discovering that your hearing aids have a feature specifically designed to help in situations like this. That's exactly what happened to Johnson Audiology patient Kathy Young. During a particularly noisy dinner with friends, Kathy decided to try Edge Mode+, a specialized feature on her new hearing aids. After recently working with Dr. Hannah Dearth, she noticed an immediate difference. “I was stunned by the immediate difference,” Kathy shared. “I was able to contribute, because I could hear what was being said.” Her experience raises an important question: Are you getting everything you can out of your hearing technology? Modern hearing aids offer far more than simple amplification. Depending on the manufacturer, model, and technology level, they may include sophisticated features designed to improve speech clarity, adapt to changing environments, and make everyday listening more convenient. Here are several capabilities worth exploring. 1. Specialized Listening Programs and Speech Clarity in Noise One of the most valuable developments in hearing technology is the ability to adjust sound processing for different listening situations. Think about the difference between sitting in a quiet living room and having dinner in a crowded restaurant. The listening demands are completely different. Many modern hearing aids automatically adapt their settings based on the surrounding environment. Some also offer specialized listening programs that can be activated when additional support is needed. Depending on your devices, these features may help by: Adjusting microphone directionality to focus on speech. Managing competing background noise. Changing how certain frequencies are amplified. Providing additional processing for particularly difficult listening situations. Higher technology levels may offer more sophisticated processing for complex environments, including restaurants, group conversations, and situations with multiple speakers. Kathy's experience with Edge Mode+ is one example of how a specialized feature can make a meaningful difference. Of course, no hearing aid can eliminate every listening challenge. But understanding what your technology is designed to do can help you use it more effectively and set realistic expectations. What to ask your audiologist: “What features do my hearing aids have for noisy environments, and when should I use them?” 2. Smartphone Apps That Give You More Control Many hearing aids can connect to a smartphone app, allowing you to make adjustments without touching the devices themselves. Depending on your hearing aids, an app may allow you to adjust volume, switch listening programs, check battery levels, or make limited changes to how sound is processed. Some apps also offer features such as finding misplaced hearing aids or contacting your hearing care provider for assistance. For example, if you're struggling to understand someone in a restaurant, you may be able to select a different listening program directly from your phone. However, not every adjustment is appropriate for every situation. Your audiologist can help you understand which controls are useful and when to use them. What to ask your audiologist: “Is there an app for my hearing aids, and can you show me the features I should know about?” 3. Bluetooth Connectivity for Everyday Convenience Modern hearing aids can stream audio directly from compatible smartphones, televisions, and other devices, making everyday listening more convenient. Whether you're taking a phone call, watching television, or enjoying music and podcasts, streaming audio through your hearing aids may provide a clearer, more personalized listening experience. Connectivity varies by manufacturer and model, and some devices require additional accessories. What to ask your audiologist: “Can my hearing aids connect to my phone or television, and can you help me set that up?” 4. Personalized Adjustments and Follow-Up Care Even the most advanced hearing technology works best when it's appropriately fitted and adjusted for the person wearing it. Your hearing needs, listening environments, and personal preferences are unique. That's why hearing aid care shouldn't end when you leave your initial fitting appointment. Follow-up visits give your audiologist an opportunity to evaluate your experience, make adjustments, answer questions, and help you understand features you may not have explored. If you're struggling in a particular environment, be specific. Instead of simply saying, “I'm having trouble hearing,” explain where the difficulty happens. For example: “I can hear people at dinner, but I struggle when several people speak.” “Phone calls are still difficult to understand.” “I hear my family well at home, but restaurants are challenging.” “I'm not sure when I should change listening programs.” These details can help your audiologist identify potential solutions and determine whether adjustments, additional features, or accessories might be helpful. What to ask your audiologist: “Can we review my hearing aid settings and make sure I'm using the features that fit my lifestyle?” What If Your Hearing Aids Don't Have These Features? Hearing technology has changed significantly over the years, and not every device offers the same capabilities. If you've worn the same hearing aids for several years, newer models may offer improvements in sound processing, connectivity, and personalization that weren't available when you purchased your current devices. That doesn't automatically mean you need new hearing aids. But if you're consistently struggling in situations that matter to you, it may be worth exploring whether your current devices can be adjusted or whether newer technology could offer additional support. At Johnson Audiology, our Doctors of Audiology work with the industry's leading hearing aid manufacturers, allowing us to recommend technology based on your individual hearing needs, lifestyle, and preferences. Your Hearing Aids May Have More to Offer Kathy Young's experience is a reminder that sometimes a meaningful improvement comes from discovering a feature you didn't realize could help. Whether you've been wearing hearing aids for a few months or several years, taking the time to understand your technology can make a difference in your everyday listening experience. You don't have to figure it all out on your own. Our team at Johnson Audiology is here to help you understand your hearing aids, explore available features, and make the most of the technology you already have.
