- Kidney disease and hearing loss can occur together, although research is still clarifying how strongly they are connected.
- A baseline hearing test can document changes early and help guide communication care alongside ongoing kidney care.

If you or someone you care for has chronic kidney disease, hearing may not be the first health concern that comes to mind. Still, the kidneys and the inner ear rely on some similar processes to manage fluid, electrolytes, and specialized tissues. Researchers are studying whether kidney disease, related health conditions, certain medications, or dialysis may contribute to hearing and balance changes.
The evidence is not simple. Several reviews and population studies report that hearing problems are more common among people with chronic kidney disease. Other research has not found a clear link between declining kidney function and new hearing loss. The practical takeaway is not that kidney disease automatically causes hearing loss. It is that hearing changes deserve attention, especially when communication is becoming more difficult.
What Is Chronic Kidney Disease?
Chronic kidney disease, often shortened to CKD, means the kidneys are damaged or cannot filter blood as well as they should over time. Healthy kidneys remove waste and extra fluid, help balance minerals, support red blood cell production, and contribute to blood pressure regulation.
CKD can develop gradually. Many people have few obvious symptoms in their early stages, so blood and urine tests are important for diagnosis and monitoring. Diabetes and high blood pressure are common risk factors, but kidney disease can have many causes. A physician or kidney specialist should answer questions about kidney function, testing, and treatment.
Why Researchers Study the Kidneys and the Inner Ear
The inner ear contains the cochlea, a delicate structure that converts sound vibrations into signals the brain can interpret. The cochlea depends on carefully controlled fluid and electrolyte conditions. Kidney tissue also uses specialized transport systems to regulate fluid, salts, and other substances.
A 2024 review in Nature Reviews Nephrology described several developmental, structural, and physiological connections between the kidney and the cochlea. Shared mechanisms do not prove that one condition directly causes the other. They do help explain why researchers continue to study hearing loss in people with kidney disease.
Possible contributors include:
- Changes in fluid and electrolyte balance that may affect inner-ear function
- Health conditions that can affect both kidney and hearing health, including diabetes and cardiovascular disease
- Some medications that may be ototoxic, meaning they can damage hearing or balance in certain circumstances
- Genetic conditions, such as Alport syndrome, that can involve both the kidneys and hearing
- Treatment-related factors that may affect some people receiving dialysis
These possibilities vary widely from person to person. An audiologist cannot diagnose kidney disease, and a kidney specialist does not replace a hearing evaluation. Coordinated care helps each professional address the part of the picture within their expertise.
What Does the Research Show?
Recent research supports taking the hearing loss and kidney disease connection seriously, but it also calls for careful wording.
A 2024 review discussed epidemiological evidence linking chronic kidney disease with a higher risk of sensorineural hearing loss. Another 2024 systematic review found that studies of people with CKD, including people receiving hemodialysis, frequently reported hearing, tinnitus, or balance abnormalities.
However, a 2020 longitudinal study that followed adults over time did not find a statistically significant association between kidney function measured with a creatinine-based equation and incident speech-frequency hearing loss. Differences in study design, patient groups, hearing measures, kidney measures, medications, and follow-up periods can affect results.
This mixed evidence is important. CKD should be viewed as a reason to stay alert to hearing changes, not as proof that hearing loss is inevitable.
Hearing Changes Worth Discussing
Hearing loss often develops gradually, and family members may notice it before the person experiencing it does. Consider scheduling a professional hearing evaluation if you notice:
- Speech sounds muffled or unclear
- Frequent requests for repetition
- Difficulty following conversations in restaurants or other noisy places
- A need to raise television, phone, or radio volume
- Trouble hearing higher-pitched voices or sounds
- New or persistent ringing, buzzing, or other tinnitus
- Increased effort or fatigue during conversations
- A sudden change in hearing in one or both ears
Sudden hearing loss is different from a gradual change. A sudden drop in hearing, especially in one ear, should be treated as urgent and evaluated promptly by a medical professional.
Can Kidney Medications Affect Hearing?
Some medications can affect hearing or balance, but the risk depends on the specific drug, dose, treatment length, kidney function, and other health factors. Certain antibiotics and loop diuretics are among the medications that may have ototoxic effects in some situations. These medicines can also be medically necessary.
Do not stop or change a prescribed medication because of something you read online. Instead, tell the prescribing clinician and your audiologist about any new hearing, tinnitus, or balance symptoms. Bring an up-to-date medication list to appointments so your care team can review possible contributors and decide whether additional monitoring is appropriate.
How a Hearing Evaluation Can Help
A hearing evaluation provides more than a pass or fail result. It establishes a baseline and shows the type and degree of any hearing loss. Depending on your needs, testing may include a discussion of symptoms and medical history, an examination of the ear canals, pure-tone testing, speech testing, and other measures selected by the audiologist.
If hearing loss is identified, recommendations depend on the results, communication goals, health history, and daily listening needs. Options may include communication strategies, assistive listening technology, hearing aids, medical referral, or periodic monitoring.
A baseline can be especially useful before a noticeable problem develops. If hearing changes later, the audiologist can compare new results with the earlier test instead of relying only on memory.
Practical Steps for Protecting Communication
People managing kidney disease often have many appointments and treatment instructions. Clear communication matters. These habits can make important conversations easier:
- Ask clinicians to face you and reduce background noise when possible
- Request written instructions or use an approved patient portal for follow-up details
- Bring a trusted family member or care partner to complex appointments
- Repeat key instructions back in your own words to confirm understanding
- Use properly fitted hearing aids or assistive devices consistently if they have been recommended
- Protect your ears from excessive noise and use appropriate hearing protection
- Report new hearing, tinnitus, or balance symptoms instead of waiting for them to become severe
When to Coordinate With Your Care Team
Tell your primary care clinician, nephrologist, or other treating professional about hearing or balance changes. Tell your audiologist about kidney disease, dialysis, diabetes, cardiovascular conditions, and current medications. That shared context helps the team interpret symptoms and decide whether a medical referral or monitoring plan is needed.
Seek prompt medical care for sudden hearing loss, severe new dizziness, weakness, facial drooping, chest pain, confusion, or other urgent symptoms. A routine hearing appointment is not a substitute for an emergency evaluation.
Schedule a Hearing Test in Wapakoneta or Sidney
Kidney disease does not mean hearing loss is certain, but communication changes should not be ignored. A professional hearing evaluation can document your current hearing, identify problems that may need attention, and give you a useful baseline for the future.
Auglaize and Sidney Audiology serves patients at offices in Wapakoneta and Sidney, Ohio. Contact the practice to schedule a hearing test and bring a current medication list along with any questions about changes you have noticed.
