As a podiatrist, I’ve treated hundreds of feet affected by diabetes – from the tiniest blister that won’t heal, to severe infections that sadly led to amputations. The truth is, while we can’t “cure” diabetic foot, we can catch problems early, prevent serious complications, and in many cases, avoid hospitalisation altogether.
In my Melbourne clinic, I see people every week who had no idea they were walking around with nerve damage, poor circulation, or pressure sores brewing under thick calluses. The earlier we step in, the better the outcome.
This guide is designed to help you understand what’s really going on in your feet, why it happens, and what you can do – starting today – to stay on top of it.
What Is Diabetic Foot, Really?
Let me paint you a picture. Imagine standing on a bindi in your backyard but not feeling it. You go about your day — driving, walking, even slipping into thongs — completely unaware there’s a small wound brewing beneath your foot. By the time it’s noticed, it might already be infected. That’s the danger of diabetic foot.
Diabetic foot refers to a group of serious foot problems that happen because diabetes affects your circulation and nerve supply. It doesn’t happen overnight — but it creeps in quietly, often without pain. That’s what makes it so tricky, and so dangerous.
I’ve treated people who were shocked to learn they had ulcers under their feet — some hadn’t felt a thing in years.
What’s Going On Inside: The Basics
Long-term high blood sugar damages two critical systems in your body:
1. Nerves (Peripheral Neuropathy)
- You stop feeling small injuries, pressure, and sometimes even hot surfaces.
- One bloke I treated stepped on a hot tile around his pool and never knew he’d burned himself until his skin blistered.
2. Blood Vessels (Peripheral Arterial Disease)
- Blood struggles to reach your toes. Healing slows right down. Even small cuts become serious.
In Aussie terms — your feet become like neglected bush tracks. Dry, cracked, and full of hidden dangers.
What Diabetic Foot Looks Like: Signs and Symptoms
Keep an eye (and a mirror) on your feet. Here’s what might signal trouble:
- Numbness or tingling (like ants crawling on your skin)
- Burning pain, especially at night
- Cuts or sores that won’t heal
- Thickened nails or skin that’s breaking down
- Hair loss on the lower legs
- Skin colour changes (blue, red, purple)
- Foot ulcers, corns, or unexpected blisters
Even something as minor as dry, cracked heels can open the door to infection if unnoticed.
Who’s Most at Risk?
You’re at higher risk of developing diabetic foot if you tick any of these boxes:
| Risk Factor | Why It Matters |
| Poorly controlled blood sugar | Directly worsens nerve and vessel damage |
| History of foot ulcers or amputation | Recurrence risk is high |
| Smoking | Further restricts blood flow |
| Kidney disease | Associated with poor wound healing |
| Obesity | Increases foot pressure and breakdown risk |
| Poorly fitting shoes | Cause pressure points and hidden wounds |
| No regular podiatric care | Problems go unnoticed for too long |
One patient I saw had worn the same rigid work boots for years. He had calluses so thick you could knock on them — underneath, a deep ulcer was brewing.
Common Complications
Here’s what we aim to prevent:
- Ulcers: Often start small and painless, but can turn serious fast.
- Infections: Cuts, blisters, or nail issues can become infected and spread.
- Charcot Foot: A condition where weakened bones collapse. Foot shape changes, balance goes out the window.
- Gangrene: When tissue dies. This is when we start talking about amputation.
Prevention is Everything
Here’s the kicker — most of these complications are preventable.
We’ll dive into foot care, footwear, and daily habits next. But if there’s one takeaway from this section, it’s this:
Don’t wait until something hurts. Pain is often the last warning sign your feet will give you.
Managing Diabetic Feet: What Actually Works
Managing diabetic feet isn’t about quick fixes — it’s about consistency, routine, and getting the right support. Below are the key pillars I stress to every patient. Miss one and the whole foundation can wobble.
1. Daily Foot Checks (Non-Negotiable)
Why it matters:
Most foot wounds start out small and silent. By the time pain kicks in, the damage is often done.
How to do it:
- Check tops, soles, heels, and between your toes daily.
- Use a mirror or ask a partner if you can’t see the bottom.
- Look for: redness, swelling, cuts, blisters, nail changes, or warm spots (a sign of inflammation).
A patient of mine once noticed a warm patch on his sole. We caught a pressure ulcer before the skin broke — dodged a hospital stay.
Checklist:
No cuts or cracks
Nails look tidy
No new blisters or bruising
Skin colour looks even
Feet feel the same temperature
2. Footwear That Protects (Not Just Looks Good)
Why it matters:
Shoes that rub, pinch or lack support can create ulcers — especially if you can’t feel the damage being done.
What to look for in good diabetic shoes:
| Feature | Why It Matters |
| Wide, deep toe box | Avoids pressure on toes and nails |
| Cushioned soles | Reduces shock and skin stress |
| No internal seams | Prevents rubbing and blisters |
| Soft upper material | Adapts to swollen or misshapen feet |
| Supportive heel and arch | Helps with alignment and balance |
Bonus tip:
Break in new shoes slowly. Wear them for 1–2 hours a day at first, inspecting your feet each time you take them off.
Real story:
I treated a netball coach from Geelong who wore narrow flats every day. She came in with a toe ulcer under a nail that had gone black — all from unnoticed pressure. We got her into medical-grade footwear and she hasn’t looked back.
3. Good Foot Hygiene (But Not Overdoing It)
Why it matters:
Cracks, fungus, and skin breakdown make great homes for bacteria.
Daily routine:
- Wash your feet daily in lukewarm water (not hot! Test with your elbow if unsure).
- Use pH-balanced soap or plain water.
- Dry thoroughly — especially between the toes.
- Moisturise tops and soles, but skip between the toes (to avoid fungal overgrowth).
- Change socks daily — cotton or bamboo blends breathe better in our Aussie heat.
Optional add-ons:
- Antifungal powder if you’re prone to athlete’s foot.
- Pumice or foot file once a week for rough skin (never razors or blades).
If you can’t reach your feet safely, ask your podiatrist or a nurse. Don’t wing it — I’ve seen DIY jobs end in infections.
4. Nail & Skin Care (No Bathroom Scissors, Please)
Why it matters:
Overgrown nails and thick skin may seem harmless — until they split open or dig into the flesh. I’ve seen ingrown toenails cause infections that hospitalised patients.
Here’s the safe way to handle it:
- Trim nails straight across — don’t dig into the corners.
- Use a nail file to round the edges if needed.
- Moisturise dry skin (heel cracks are entry points for bacteria).
- Never use corn pads or chemical removers from the chemist — they’re too harsh for diabetic skin.
- Don’t cut calluses at home — that’s a podiatrist’s job.
I had a bloke from Frankston who “shaved” a corn off with a Stanley knife. Ended up in surgery for an infected ulcer that reached the bone.
When in doubt, let your podiatrist take care of your nails and hard skin. It’s worth it — especially if you’ve lost sensation or have poor eyesight.
5. Gentle Exercise = Better Blood Flow
Why it matters:
Moving your body helps pump blood through your legs and feet, which aids healing and reduces inflammation. It also helps regulate blood sugar.
What works well for most people with diabetes:
| Activity | Why It’s Good |
| Walking | Improves circulation and is free |
| Swimming | No pressure on the feet or joints |
| Stationary cycling | Low impact, indoor-friendly |
| Chair-based moves | Great for those with mobility issues |
Do’s and Don’ts:
Wear proper shoes and check your feet before and after
Start slow — even 10 minutes counts
Don’t exercise if you have an open wound or new swelling
One of my retired patients joined a gentle aqua aerobics class in Melbourne’s west. Her foot health, mood, and energy levels all improved within weeks.
6. Keep Blood Sugar in the Target Range
Why it matters:
High blood sugar damages blood vessels and nerves, setting the stage for diabetic foot problems.
Everyday blood sugar tips:
- Follow a balanced diet with steady carbs (think low-GI options)
- Eat regularly to avoid big sugar spikes
- Take medications as prescribed
- Monitor your BGLs as advised by your doctor or diabetes educator
- Stay hydrated — especially in summer when dehydration creeps in
Work with a team:
- Dietitian for meal planning
- GP for medication reviews
- Diabetes educator for lifestyle changes
One young tradie I worked with had wildly fluctuating blood sugar due to erratic meals and energy drinks. After seeing a dietitian and adjusting his schedule, his foot infections settled dramatically.
7. Professional Foot Care Is a Game-Changer
Why it matters:
Even if your feet look “fine,” problems often brew beneath the surface. Regular check-ups can catch them before they become serious.
How often should you see a podiatrist?
| Risk Level | Check-up Frequency |
| Low risk | Every 6–12 months |
| Moderate to high risk | Every 1–3 months |
| Ulcer history | Every 4–6 weeks (or more) |
At Well Heeled Podiatry, I use tools like:
- Doppler ultrasound to check foot circulation
- Monofilament testing for sensation
- Clinical photography to track skin changes over time
- Nail and callus debridement — safely and painlessly
I always say: “Don’t let your feet go silent on you.” A 30-minute podiatry visit could prevent months in a hospital bed.
Why Early Intervention Matters
When it comes to diabetic foot, early is everything.
Too often I meet people who delayed getting help, thinking “It’s just a bit of redness” or “It doesn’t even hurt.” But that small warning sign can turn into a serious infection faster than you’d expect — especially in warmer, more humid Aussie months.
What Early Intervention Can Prevent
| Without Early Action | With Early Care |
| Minor cuts become ulcers | Wounds treated early and heal well |
| Infections spread to bone | Infections contained quickly |
| Pressure deformities worsen | Charcot foot detected and managed |
| Tissue death (gangrene) | Blood flow assessed, risk reduced |
| Amputation becomes necessary | Limbs and mobility preserved |
Protecting Mobility and Independence
Your feet are your foundation. If they’re not healthy, everything becomes harder — walking, driving, even just getting out of bed. Especially as we age, maintaining our mobility means keeping our freedom.
I’ve seen elderly patients bounce back after simple interventions — like new orthotic-friendly shoes and a consistent skin care routine — simply because they acted early.
Reducing Healthcare Costs
Delays lead to:
- ER visits
- Long hospital stays
- IV antibiotics
- Surgery and rehab
In contrast, early check-ups and professional care are far more affordable and far less stressful — for both patients and their families.
The Emotional Toll
Don’t underestimate the mental load. Chronic wounds, dressings, and reduced mobility can take a real emotional toll — leading to depression, anxiety, and social withdrawal. Staying on top of your foot health can lift that cloud.
One of my patients said it best:
“I feel like I got my life back. I was afraid to leave the house for months, always worrying about infection. Now I feel in control again.”
Diabetic Foot Self-Care Checklist
Here’s a simple weekly checklist you can print or keep on your fridge:
| Task | Frequency | Done? ✅ |
| Inspect feet (top, bottom, toes) | Daily | |
| Moisturise (avoid between toes) | Daily | |
| Change socks (breathable fabric) | Daily | |
| Check inside shoes for debris | Daily | |
| Trim toenails carefully or book in | Every 4–6 weeks | |
| Foot check-up with podiatrist | As advised | |
| Monitor blood sugar levels | Daily/As advised | |
| Move your body safely | Most days |
Final Word from Monique
While there’s no silver bullet “cure” for diabetic foot, there’s something far more powerful — prevention.
As a podiatrist, I’ve seen firsthand how small, consistent actions can save limbs, independence, and lives. Whether you’re newly diagnosed or managing diabetes for decades, it’s never too late to give your feet the attention they deserve.
If you’re unsure where to start, book a diabetic foot assessment. A 30-minute chat could make all the difference.
