Key Takeaways
- People with chronic kidney disease may have a higher risk of hearing loss, especially sensorineural hearing loss which affects the inner ear or hearing nerve.
- Research has found that hearing loss is more common among people with chronic kidney disease (CKD). In a large Australian population study, more than 54% of adults aged 50 years and above with moderate CKD had some degree of hearing loss, compared with approximately 28% of those without CKD.
- Conditions such as diabetes, high blood pressure, cardiovascular disease, and ageing can affect both kidney function and hearing health. Researchers believe these shared risk factors may partly explain why hearing loss is more common among people with chronic kidney disease.
- Regular hearing evaluations can detect early signs of hearing impairment, facilitating timely intervention.
- If you have kidney disease, unexplained tinnitus, or difficulty hearing speech clearly, a professional hearing test is a sensible part of your wider health plan.
Introduction: Why Kidney Health Matters for Your Hearing
Imagine an older adult in Malaysia managing chronic kidney disease. He also struggles to follow family conversation during Hari Raya, Chinese New Year, or a noisy restaurant dinner. Everyone seems to be “mumbling”, especially grandchildren and those with soft voices. Many people assume this is “just part of getting old”. While age-related hearing loss is common, it may not always tell the whole story. Research suggests that chronic kidney disease (CKD) may also increase the risk of hearing loss, yet this connection is often overlooked by families and caregivers.
At Clarisound, we view hearing health as part of whole-body health. Researchers believe the kidneys and inner ear share certain biological similarities, including a reliance on healthy blood flow, fluid balance, and specialised cellular structures. In this guide, we explore the possible connection between kidney disease and hearing loss, common warning signs, risk factors, and how professional hearing care can help support better hearing and quality of life.
What Is Chronic Kidney Disease (CKD)?
Your kidneys do much more than remove waste from the body. They help regulate fluid balance, blood pressure, minerals, and other processes that are essential for overall health.
Chronic kidney disease (CKD) develops when the kidneys gradually lose function over months or years. Diabetes and high blood pressure are the leading causes. Because CKD can affect blood vessels, nerves, and metabolic processes throughout the body, researchers have explored whether it may also influence hearing health.
Early CKD can be silent. When symptoms appear, they may include:
- tiredness or poor concentration
- swelling in the ankles or legs
- foamy urine
- changes in urination
- nausea, poor appetite, or general dysfunction in the body
Monitoring kidney function includes routine blood and urine tests to track how well the kidneys filter waste. Routine tests like eGFR and urine albumin-to-creatinine ratio can help in spotting early renal decline. If left untreated, CKD can progress to kidney failure, necessitating dialysis or a kidney transplant for survival.
Chronic kidney disease (CKD) is a growing health concern in Malaysia. According to findings from the National Health and Morbidity Survey (NHMS), the prevalence of CKD among Malaysian adults increased from 9.1% in 2011 to 15.5% in 2018—equivalent to nearly 1 in 6 Malaysian adults. Many individuals remain undiagnosed because CKD often develops gradually and may not cause noticeable symptoms in its early stages.
Globally, CKD affects hundreds of millions of people and is increasingly recognised as a major public health challenge. As Malaysia’s population ages and conditions such as diabetes and high blood pressure become more common, maintaining kidney health is becoming increasingly important.
How Kidney Disease and Hearing Loss Are Biologically Connected
The ear and kidneys look unrelated, but they share sensitive tiny blood vessels and specialised cell structures. The kidneys and inner ear share several biological similarities. Both rely on specialised mechanisms to regulate fluid and electrolyte balance, and both develop from related tissues during fetal development. Researchers believe these shared characteristics may partly explain the association between chronic kidney disease and hearing loss.
Reduced kidney function can allow waste products and fluid changes to build up in the body. These changes may affect the inner ear, especially the cochlea, which converts sound into nerve signals. This is why the most common type linked with CKD is sensorineural hearing loss, meaning damage to the cochlea or hearing nerve rather than a simple blockage in the ear.
The association is supported by population-based research. In the Blue Mountains Hearing Study, 54% of older adults with moderate chronic kidney disease had some degree of hearing loss, compared with 28% of those without CKD. Although this does not establish a direct cause-and-effect relationship, it provides strong evidence that hearing loss is significantly more common among people living with chronic kidney disease.
Why Do Kidney Disease and Hearing Loss Often Occur Together?
Diabetes, high blood pressure, cardiovascular disease, and ageing are risk factors for both chronic kidney disease and hearing loss. These conditions can affect the small blood vessels and nerves that the kidneys and inner ear depend on to function properly. As a result, damage to one system may be accompanied by changes in the other.
| Risk factor | Why it matters |
|---|---|
| High blood pressure | Can damage the small blood vessels that both the kidneys and inner ear rely on to function properly. |
| Diabetes | Can affect blood vessels, nerves, and metabolic processes involved in both kidney function and hearing. |
| Cardiovascular disease | Reduced blood flow may impair both kidney function and the health of delicate hearing structures in the inner ear. |
| Smoking | Increases vascular damage and oxidative stress, which may contribute to both kidney disease and hearing loss. |
| Ageing | The risk of both chronic kidney disease and hearing loss increases with age, making the two conditions more likely to occur together. |
| Noise exposure | While not a cause of kidney disease, prolonged exposure to loud noise may further increase the risk of hearing loss in individuals who already have CKD or other vascular risk factors. |
Specific Kidney Conditions Linked With Hearing Loss
Some kidney conditions appear to have a stronger association with hearing loss than others. Studies have found higher rates of mild, moderate, and severe hearing loss among people with advanced chronic kidney disease, particularly those with stages 3–5 CKD and end-stage kidney disease.
People receiving dialysis may face additional hearing-related risks. Researchers have suggested that fluid and electrolyte fluctuations, underlying vascular disease, certain medications, and the overall burden of advanced kidney disease may all contribute to changes in hearing over time.
Alport Syndrome: A Genetic Condition Affecting Both Kidney and Hearing Health
Alport syndrome is one of the clearest examples of the connection between kidney disease and hearing loss. This inherited condition is caused by defects in type IV collagen, an important structural component found in the kidneys, inner ear, and eyes. As a result, affected individuals may develop progressive kidney disease, hearing loss, and certain eye abnormalities.
A family history of kidney disease, hearing loss, or unexplained eye abnormalities may warrant further medical evaluation, particularly if a child or young adult is found to have blood or protein in the urine. Early diagnosis can help guide monitoring and management of both kidney and hearing health.
Hearing loss associated with Alport syndrome often develops during late childhood or adolescence rather than being present at birth.
Can Kidney Medications Affect Your Hearing?
People with chronic kidney disease may be more vulnerable to medication-related side effects because the kidneys play an important role in filtering and clearing many drugs from the body.
Some medications used to treat kidney disease and its complications can affect hearing, tinnitus (ringing in the ears), or balance. These are known as ototoxic medications. Examples include certain antibiotics, powerful diuretics, and high or prolonged doses of some pain medications.
Frequent or long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, naproxen, and diclofenac, may increase the risk of kidney damage and has also been associated with hearing-related side effects in some individuals.
However, this does not mean these medications should be avoided. Many are essential treatments that help manage serious medical conditions and may be life-saving. The benefits often outweigh the risks, particularly when treatment is carefully monitored by a healthcare team.
If you notice ringing in the ears, dizziness, balance problems, or sudden changes in hearing after starting a new medication, speak with your doctor and audiologist. Never stop or adjust prescribed medications without medical advice.
Warning Signs: When Kidney Health Might Be Affecting Your Hearing
The early signs of hearing loss are often subtle. Many people adapt without realising their hearing has changed, while family members become increasingly aware of the problem. This is especially common among older adults with conditions such as diabetes, high blood pressure, or chronic kidney disease.
Watch for:
- turning the TV or phone volume higher
- asking “pardon?” more often
- difficulty following speech in a kopitiam or busy family dinner
- hearing sound but missing clarity
- needing to lip-read
- tinnitus, buzzing, or ringing
- one ear suddenly seeming worse than the other
If you have chronic kidney disease or are taking medications that may affect hearing, regular hearing assessments can help monitor changes over time.
A sudden loss of hearing is not a normal part of ageing and should not be ignored. Sudden sensorineural hearing loss, which develops over hours or days, requires urgent assessment by an ENT specialist.
Protecting Both Kidney Health and Hearing Health
Although hearing loss and chronic kidney disease are not always preventable, there are practical steps that may help reduce risk and support long-term health. Many of the same factors that protect the kidneys also help maintain healthy blood vessels, nerves, and hearing function.
Helpful steps include:
- Managing blood pressure with your doctor’s guidance
- Keeping blood sugar under good control if you have diabetes
- Attending regular kidney check-ups and following medical advice
- Following a balanced diet that supports kidney and cardiovascular health
- Reducing excess sodium, added sugars, and unhealthy fats
- Staying physically active most days of the week
- Avoiding smoking
- Protecting your ears from prolonged exposure to loud noise
- Avoiding unnecessary or prolonged use of NSAIDs (such as ibuprofen and naproxen) unless advised by your doctor
The connection between kidney health and hearing health highlights an important point: many of the same habits that protect the kidneys may also help preserve hearing. Managing chronic conditions early and maintaining regular medical follow-up can support long-term health and quality of life.
How Clarisound Supports Customers with Hearing Loss
Since 2001, Clarisound has helped thousands of individuals improve their hearing through a comprehensive rehabilitation approach guided by MAHPC-registered audiologists and international best practices.
Our pathway is simple: Accurate Diagnosis → Expert Fitting → Innovative Hearing Technology → Proactive Aftercare. Because successful hearing outcomes depend on much more than the device itself.
At Clarisound, we take a holistic approach to hearing care. During your consultation, our audiologists will review your hearing concerns, relevant medical history, medications, communication challenges, and lifestyle needs. We then conduct a comprehensive hearing assessment and explain the findings in clear, everyday language, so you can make informed decisions about your hearing care.
All assessments and fittings are carried out by MAHPC-registered audiologists. Recommendations are personalised to your hearing profile, listening needs, and lifestyle goals. We also use Real-Ear Measurement (REM), the internationally recognised gold standard for hearing aid fitting, to verify that your hearing aids are delivering the right level of amplification for your unique ears.
Established in 2001, Clarisound is independently owned and operated. We work with trusted hearing technology partners such as Signia and Rexton, selected for their innovation, reliability, and value. Our commitment extends beyond the initial fitting through proactive long-term aftercare, including regular hearing aid checks, professional cleaning, fine-tuning, and ongoing support as your hearing needs evolve over time.
When Hearing Aids Help – and What to Expect
Most CKD-related hearing loss is sensorineural, so it is usually not reversed by medication or surgery. However, modern hearing aids can often make speech clearer and reduce listening effort, especially in noisy Malaysian environments.
A hearing aid should not simply make everything louder. The goal is clarity over volume: clearer speech at family gatherings, easier conversations in cafés, and less fatigue from trying to guess missing words.
There is also an adjustment period when starting to use hearing aids. While many people notice benefits immediately, the brain often needs time to adapt to sounds it has not heard clearly for months or even years. Everyday sounds may seem unusually noticeable at first, and listening can feel more effortful as the brain relearns how to interpret speech and environmental sounds.
This is one reason why hearing rehabilitation is about more than simply fitting a device. Ongoing support from an audiologist can help you adjust more comfortably, optimise hearing aid settings, address concerns, and achieve the best possible outcomes over time.
Communication strategies also play an important role. Facing the person speaking, reducing background noise where possible, and speaking clearly rather than shouting can make conversations easier and less tiring for everyone involved.
Protecting Your Hearing When You Have Kidney Disease
Any noticeable change in hearing deserves attention. For individuals with chronic kidney disease, diabetes, high blood pressure, or cardiovascular disease, regular hearing assessments may be especially valuable because these conditions are associated with a higher risk of hearing loss.
Family members can also play an important role. Adult children often notice hearing difficulties before their parents do and can help by attending appointments, sharing observations, and supporting communication strategies at home.
At Clarisound, we believe better hearing outcomes depend on more than a hearing aid alone. Since 2001, our MAHPC-registered audiologists have followed international best practices in hearing rehabilitation through four essential pillars: Accurate Diagnosis, Expert Fitting, Innovative Hearing Technology, and Proactive Aftercare.
If you would like to better understand your hearing health, we invite you to book a free hearing test, arrange a no-obligation consultation, or speak with one of our audiologists. We are here to help you make informed decisions about your hearing care and long-term communication needs.
Frequently Asked Questions about Kidney Health and Hearing
Is hearing loss a sign that my kidneys are failing?
No. Hearing loss alone does not indicate kidney failure.
However, hearing loss is more common in people with chronic kidney disease than in the general population. If you have CKD and notice changes in your hearing, consider arranging a hearing assessment and discussing any concerns with your healthcare team.
Can improving my kidney function restore my hearing?
It depends on the cause of the hearing loss. Most hearing loss associated with chronic kidney disease is sensorineural hearing loss, which affects the inner ear or hearing nerve and is usually permanent.
While improving kidney health is important for overall wellbeing, it does not typically restore hearing that has already been lost. However, good management of kidney disease and related conditions such as diabetes and high blood pressure may help reduce the risk of further hearing decline.
If hearing loss is affecting communication and quality of life, a hearing assessment can help determine whether hearing rehabilitation options such as hearing aids may be beneficial.
How often should someone with chronic kidney disease check their hearing?
There are currently no widely accepted guidelines that require routine hearing tests for everyone with chronic kidney disease. However, because hearing loss appears to be more common among people with CKD, many individuals may benefit from a baseline hearing assessment, particularly if they are over 50 or have noticed changes in their hearing.
If hearing is normal, periodic hearing checks every year may be reasonable, depending on age, overall health, and risk factors. Earlier assessment is recommended if you experience symptoms such as hearing difficulties, tinnitus, dizziness, sudden changes in hearing, or concerns about medication-related hearing effects.
Are hearing aids safe for people on dialysis or after a kidney transplant?
Yes. Hearing aids do not interfere with dialysis, kidney transplant medications, or other kidney treatments. They are safe for most people living with chronic kidney disease and can help improve communication, social engagement, and quality of life when hearing loss is present.
Your audiologist may take your overall health, medications, dexterity, and lifestyle needs into account when recommending hearing technology and planning ongoing care.
Should I tell my nephrologist that I am getting hearing aids?
It is generally a good idea to keep your healthcare providers informed about significant changes in your health, including hearing loss and hearing rehabilitation.
While hearing aids do not affect kidney treatment, hearing assessment findings may provide useful information about your overall health. If appropriate, hearing test results can be shared with your nephrologist or other healthcare professionals as part of your ongoing care.
At Clarisound, we can provide hearing test reports and work with you to ensure you have the information you need to discuss your hearing health with your medical team.
