Diabetes and feet: warning signs not to ignore
Daily foot checks and prompt assessment of wounds are especially important for people with diabetes and kidney disease.
7 min read · Updated 2026-08-22Key points
- A small wound may go unnoticed when sensation in the feet is reduced.
- Redness, warmth, swelling, discharge or a colour change require prompt assessment.
- Risk is particularly high with vascular disease, previous ulcers and dialysis.
What to check every day
Check the soles, between the toes, the nails and areas pressed by footwear. If you cannot see the sole, use a mirror or ask someone you trust for help. Look for blisters, cracks, calluses, wounds, colour changes and differences in skin temperature.
Do not cut corns yourself or treat an open wound with harsh products. Arrange an assessment with your care team, especially if you already have reduced sensation or poor circulation.
Why dialysis adds risk
A new systematic review of 64 observational studies found that foot ulcers and amputations are common among people with diabetes and end-stage kidney disease. The evidence is heterogeneous, but consistently supports early multidisciplinary follow-up.
- wear footwear that does not rub and do not walk barefoot
- ask whether circulation and sensation should be checked during appointments
- report every new wound to your healthcare team without delay
When assessment is urgent
Rapidly spreading redness, black or blue skin, an unpleasant smell, pus, fever or sudden deterioration can indicate a serious infection or impaired circulation.
