Wound Care for Diabetics

Why minor wounds are major risks in diabetes — and how to prevent disaster

In people with diabetes, a small cut on the foot or a blister from tight shoes can escalate within days to deep infection, gangrene, and amputation. Nigeria has one of the highest rates of lower-limb amputation from diabetic foot disease globally — driven by delayed presentation, poor foot care habits, and late access to specialist care. This guide teaches prevention and what to do when wounds appear.

Signs and Symptoms

✓ A wound on the foot that is slow to heal (more than 2 weeks without improvement)
✓ A foot wound that is painless despite appearing serious (loss of pain sensation from neuropathy)
✓ Redness, warmth, or swelling around a wound
✓ Pus, foul smell, or dark discolouration at a wound site
✓ A blister, callus, or corn that has broken open
✓ Black or dark tissue at or around a wound (necrosis — tissue death)
✓ Foot pain at rest or at night (critical limb ischaemia — vascular emergency)

Risk Factors

When to Seek Help

Any wound on a diabetic footEvery foot wound in a diabetic needs professional assessment within 24 hours — do not wait to see if it heals on its own.
Wound with redness, swelling, or pusActive infection — needs urgent medical review and likely antibiotics within hours, not days.
Black tissue or spreading redness up the legEmergency — go to hospital immediately. This may be gangrene or necrotising fasciitis requiring urgent surgery.
Foot that is cold, pale, or blue with rest painCritical limb ischaemia — vascular emergency requiring same-day hospital assessment.

Tests & Diagnosis

🧪 Blood glucose and HbA1c
Optimising glycaemic control is central to wound healing — check urgently in all diabetic wound patients.
🧪 Wound swab and culture
Identifies the infecting organisms and guides antibiotic choice.
🧪 X-ray of the foot
Looks for osteomyelitis (bone infection) — a devastating complication requiring prolonged antibiotic treatment or surgery.
🧪 Ankle-brachial index (ABI)
Compares blood pressure in the ankle vs arm — screens for peripheral arterial disease. ABI below 0.9 indicates significant arterial disease.
🧪 Full blood count + CRP + ESR
Indicates severity of infection and systemic response.

Treatment Options

1
Inspect feet daily
Every morning: look at all surfaces of both feet, between toes, and under the heel. Use a mirror or ask a family member if you cannot bend well. Report any change immediately to your doctor.
2
Never walk barefoot
Even inside the house. Wear protective footwear always. A simple plaster or domestic sandal is not sufficient — dedicated diabetic footwear or well-fitted closed shoes with soft insoles are needed.
3
Wound debridement and dressing
Professional removal of dead tissue and appropriate dressing (saline-moistened gauze or modern moisture-retentive dressings) — done by a nurse or doctor, not at home with unsterile equipment.
4
Antibiotics for infected wounds
Amoxicillin-clavulanate or clindamycin for mild infection; IV broad-spectrum antibiotics for moderate-severe. Duration guided by response.
5
Offloading pressure from the wound
Total contact casting or removable offloading boots remove pressure from the wound site — essential for healing. Walking on an unprotected foot wound prevents healing regardless of antibiotics.
6
Blood sugar optimisation
Aggressive glycaemic control (target HbA1c below 8% or lower if safe) dramatically improves wound healing and infection response.
7
Vascular surgery referral
If peripheral arterial disease is confirmed — angioplasty or bypass surgery restores blood flow and may save the limb.

Frequently Asked Questions

I have diabetes but my foot wound doesn't hurt — is that a good sign?
No — this is the most dangerous situation. Diabetic neuropathy causes painlessness even in severe infections. The absence of pain does not mean the wound is mild. A painless diabetic foot wound always needs urgent medical assessment.
Can a diabetic foot ulcer be treated at home?
Only very superficial, non-infected wounds in people with good circulation and good blood sugar control. Any wound in a person with neuropathy, poor circulation, or poor glucose control requires professional management. Home treatment of infected diabetic foot wounds leads to amputation.
How long does a diabetic foot ulcer take to heal?
Uncomplicated superficial ulcers with good blood supply and controlled glucose: 4–8 weeks. Deep or ischaemic ulcers: months. Wounds complicated by infection or bone involvement may require surgery. Healing is dramatically prolonged compared to non-diabetic wounds.
What should I do if I cut my toenails as a diabetic?
Cut straight across — never cut corners. File rather than cut if vision or dexterity is poor. Never cut into the skin or dig out ingrown nails — this commonly starts diabetic foot infections in Nigeria. See a podiatrist or nurse for nail care if you have neuropathy or poor vision.
Is amputation always necessary for diabetic foot?
No — early presentation and expert multidisciplinary care (vascular surgery, orthopaedics, diabetology) saves most limbs. Nigeria's high amputation rate reflects late presentation and limited specialist centre access, not inevitable disease progression. The diabetic foot can almost always be saved if treated early.
