Protecting Your Ears in Diabetes Patient Information Leaflet (4MB pdf)
What is Necrotizing Otitis Externa (NOE)?
- A serious ear infection that spreads from the ear canal to the surrounding bone and tissues.
- It is rare but more common in people with diabetes, especially if blood sugar levels are not well controlled.
- Early recognition and treatment are very important.
Why are people with diabetes at higher risk?
- Diabetes can weaken the body’s natural defenses.
- High blood sugar encourages infections to develop and heal more slowly.
- Poor blood circulation in the ear canal can make it easier for infection to spread.
Warning signs to look out for
- Severe ear pain, especially at night.
- Persistent ear discharge (often foul-smelling).
- Hearing loss or a blocked sensation.
- Redness, swelling, or tenderness around the ear.
- Pain when touching the ear.
⚠️ If you notice these symptoms, seek medical advice immediately.
How you can reduce your risk
- ✅ Keep your diabetes under control – aim for stable blood sugar levels.
- ✅ Look after your ear hygiene – gently wipe the outer ear with a cloth, but do not insert cotton buds, fingers, or objects into the ear canal.
- ✅ Protect your ears from water – keep ears dry when swimming or showering; use earplugs if advised by your doctor. Apply a smearing of Vaseline in your ears in the morning and at night time.
- ✅ Treat ear infections early – don’t ignore ear pain or discharge; see your GP promptly.
- ✅ Attend your regular diabetes check-ups – good overall health lowers your risk of infections.
What to avoid
- ❌Water entering your ears at all times.
- ❌ Do not scratch inside your ears or use cotton buds.
- ❌ Avoid using ear drops or remedies without medical advice.
- ❌ Don’t ignore persistent ear pain or discharge – early treatment is key.
When to see a doctor urgently
- If ear pain is severe or worsening.
- If you have ear discharge that does not clear.
- If pain continues despite simple treatment.
- If you feel unwell, feverish, or develop swelling around the ear.
Remember
- Necrotizing otitis externa is rare, but people with diabetes are more at risk.
- By controlling your diabetes, protecting your ears, and seeking help early, you can reduce your chances of developing this serious infection.
