Special situations
Fungal nail infection when you have diabetes
Fungal nail infection is substantially more common in people with diabetes, and the consequences of getting it wrong are more serious. This is the one group for whom we actively recommend professional care over self-treatment.
Summary
Reduced sensation and circulation mean small breaks in the skin can go unnoticed and become ulcers. Thickened nails press on the nail bed. Any foot problem in diabetes should be assessed by a podiatrist or the diabetes foot team.
Why the risk is higher
Several factors combine.
- Neuropathy masks pain that would otherwise warn you
- Reduced blood flow slows healing and nail growth
- Higher skin glucose supports fungal growth
- Thick nails create pressure points inside shoes
Treatment options
Podiatric debridement, prescribed topical or oral antifungals with monitoring, and structured foot care. Do not scrape, cut back or chemically remove nail at home.
When to seek medical advice
Immediately for any redness, warmth, discharge, ulceration or new pain, and routinely through your annual diabetic foot check.
