Why diabetic feet need specialized attention
Diabetes can cause peripheral neuropathy (loss of protective sensation), peripheral arterial disease (reduced blood flow), and impaired immune response — a combination that puts the foot at high risk for ulceration, infection and Charcot arthropathy. Many diabetic foot problems begin with minor trauma that goes unnoticed due to neuropathy, progressing to wounds that heal slowly due to poor circulation.
Regular foot assessment is essential for anyone with diabetes, regardless of whether they currently have symptoms. Early identification of risk factors (neuropathy, vascular insufficiency, deformity, prior ulcer or amputation) allows for preventive interventions that significantly reduce the risk of serious complications.
- Loss of protective sensation (neuropathy) — inability to feel cuts, blisters or pressure
- Reduced blood flow (peripheral arterial disease) — slow healing, cool foot, absent pulses
- Foot deformities — bunions, claw toes, Charcot foot — increase pressure points
- Skin changes — dryness, cracking, callus formation
- Infection risk — even minor wounds can become serious
- Prior ulcer or amputation — high risk of recurrence

Diabetic foot evaluation and management
The evaluation includes assessment of sensation (monofilament testing), blood flow (pulse examination, ankle-brachial index when indicated), skin and nail condition, deformity assessment, and footwear review. Risk stratification guides the frequency of follow-up and the type of preventive measures needed.
Management ranges from patient education and preventive foot care (appropriate footwear, daily inspection, nail care) to wound management for existing ulcers, offloading strategies, infection treatment, and vascular referral when blood flow is significantly impaired.

| Risk level | Features | Recommended approach |
|---|---|---|
| Low risk | No neuropathy, no deformity, good pulses | Annual review, education, appropriate footwear |
| Moderate risk | Neuropathy or deformity, no prior ulcer | 3–6 monthly review, preventive care, therapeutic footwear |
| High risk | Neuropathy + deformity OR prior ulcer/amputation | 1–3 monthly review, intensive prevention, specialist footwear |
| Active problem | Ulcer, infection, gangrene, Charcot | Urgent specialist care, wound management, possible hospitalization |
