Educational information, not medical advice. This article is written to help you understand common ear and hearing issues. It is not a substitute for professional diagnosis or treatment. If your symptoms are severe, sudden, or persistent, please consult a qualified doctor or audiologist. For urgent symptoms (sudden hearing loss, bleeding from the ear, severe pain with dizziness, or a head injury), seek medical care the same day.
Hearing loss is associated with diabetes, high blood pressure and heart disease, kidney disease, thyroid disorders, anaemia, sleep apnoea and some infections. These are associations, not proof that one causes the other. If you have any of them, regular hearing checks are sensible.
The direct answer
Several general health conditions are linked with a higher chance of hearing loss, including diabetes, high blood pressure and heart disease, kidney disease, thyroid disorders, anaemia, sleep apnoea and certain infections. The inner ear depends on good blood flow and healthy nerves, so conditions that affect circulation or the nervous system can affect hearing. These links are associations found in studies; they do not mean that everyone with the condition will lose hearing.
Conditions and what is known
- Diabetes and prediabetes: high blood sugar can damage small blood vessels and nerves, including in the ear. See diabetes and hearing loss and prediabetes and hearing loss.
- High blood pressure and heart disease: poor circulation can affect the cochlea. See hearing loss and heart health and what your hearing can reveal about your heart and kidneys.
- Kidney disease: associated with hearing problems, partly through shared circulation and some medicines. See kidney disease and hearing loss.
- Thyroid disorders: an underactive thyroid has been linked with hearing changes, and thyroid disease in pregnancy or childhood matters for hearing development.
- Anaemia (including iron deficiency): some studies link it with a higher risk of hearing loss.
- Sleep apnoea and heavy snoring: associated with a higher risk of hearing problems, possibly through repeated drops in oxygen.
- Obesity and high cholesterol: linked in some studies with poorer hearing.
- Autoimmune conditions: can, rarely, affect the inner ear and cause fast-progressing loss.
- Infections: mumps, measles, meningitis and some ear infections can damage hearing. See ear infections and your child's hearing.
- Medicines: some drugs are ototoxic. See medicines that damage hearing.
What this means for you
- Get a baseline hearing test, especially if you have one of these conditions or a family history of hearing loss.
- Repeat it regularly. See how often to get a hearing test.
- Keep the condition well controlled, with your doctor's advice: blood sugar, blood pressure, thyroid, iron and sleep.
- Protect your ears from noise, which adds to the risk.
- Mention any hearing change to your doctor, since it may be a clue to the underlying condition.
Hearing loss and general health
The link works both ways. Untreated hearing loss is associated with social withdrawal, low mood and faster cognitive decline in older adults. See hearing loss and dementia and does hearing loss cause depression. Treating hearing loss early is good for overall health.
