In my years of treating diabetic foot complications, I’ve come to believe that the daily foot check is the single most powerful tool a diabetic patient has. Not medication. Not surgery. The simple act of looking at your feet every day — because if you catch a problem in its earliest stage, you have time to act before it becomes a crisis. Here is the routine I recommend to every patient.
How Can Diabetics Prevent Foot Ulcers?
Diabetic foot ulcers are largely preventable. The key is consistent, informed self-care combined with regular professional monitoring. Prevention works across three levels: protecting the foot from injury, ensuring wounds are caught and treated immediately, and maintaining the blood supply through good blood sugar and cardiovascular risk control.
The Daily Foot Care Routine
Step 1: Inspect Your Feet Every Day
Check every surface of the foot — the sole, heel, between the toes, and toenails. Use a mirror to see the sole if bending is difficult, or ask a family member to check the parts you cannot easily see. Look for:
- Any new cut, blister, crack, or sore — however minor it appears
- Redness, swelling, or warmth in any area
- Changes in skin colour — pallor, blueness, or dark patches
- Changes in nail appearance — thickening, discolouration, or ingrown edges
Step 2: Wash and Dry Carefully
Wash feet daily in lukewarm water — always test the temperature with your elbow or a thermometer first, never with your feet, as neuropathy means you cannot reliably detect hot water. Dry thoroughly, paying particular attention to the spaces between toes, where moisture encourages fungal infection and skin breakdown.
Step 3: Moisturise — But Not Between the Toes
Apply a good moisturising cream to the soles and heels to prevent dryness and cracking. Do not apply cream between the toes, as this traps moisture and increases the risk of fungal infection.
Step 4: Nail Care
Cut toenails straight across, not curved at the corners, to avoid ingrown nails. File sharp edges gently. If your nails are very thick or you have poor vision, have them trimmed by a podiatrist or diabetic foot nurse rather than attempting this yourself.
Step 5: Footwear — The Most Important Protection
- Always wear shoes or slippers — never walk barefoot, even indoors
- Check inside shoes before putting them on — feel with your hand for any foreign objects or rough areas
- Wear well-fitting, cushioned shoes with enough depth and width for the toes
- Avoid pointed toes, high heels, or very tight shoes
- Change socks daily; wear seamless or inside-out socks to avoid rubbing
- If you have foot deformities, ask for a referral for custom orthotics or therapeutic footwear
Systemic Prevention — What Happens Inside Matters Too
Blood Sugar Control
Good glycaemic control is the foundation of all diabetic foot prevention. High blood sugar accelerates neuropathy, impairs immune function, and damages blood vessels. Target HbA1c levels agreed with your diabetologist are the single most important long-term protection for your feet.
Blood Pressure and Cholesterol
Both high blood pressure and elevated LDL cholesterol accelerate the arterial disease that impairs foot blood supply. Tight control of these risk factors, alongside regular vascular monitoring, reduces the risk of critical limb ischaemia.
Stopping Smoking
Smoking dramatically accelerates peripheral artery disease and is the single most modifiable risk factor for diabetic foot complications and amputation. Stopping smoking at any stage reduces this risk.
Professional Monitoring
Every diabetic patient should have their feet examined by a healthcare professional at least once a year — more frequently if neuropathy or peripheral artery disease is present. This annual foot check includes assessment of sensation, pulses, and skin condition.
My Clinical Perspective
I cannot overstate how many amputations I have seen that began with something tiny — a blister from a new pair of shoes, a minor cut while trimming nails, a small crack in dry skin. The wound itself wasn’t the problem. The problem was that nobody noticed it for two weeks. Make foot inspection as non-negotiable as taking your medication. It takes two minutes. It saves limbs.
Warning Signs to Act on Immediately
- Any new wound, sore, or blister not healing in 1–2 days
- Any redness, swelling, or warmth developing around a wound
- Dark or black skin on any part of the foot
- Foot pain at rest or at night
⚠️ Important: Diabetic foot prevention requires daily consistency. One missed foot check is all it takes for a wound to develop unnoticed. Build the habit now.
