Complications
Diabetic foot care: the daily routine that prevents most problems
Diabetic foot complications are among the most preventable serious outcomes in diabetes, and among the most common reasons for amputation in Pakistan. Almost all of them begin as something small that went unnoticed.
Why feet are so vulnerable in diabetes
Two problems combine. First, sustained high blood sugar damages nerves (neuropathy), which reduces sensation, meaning a cut, blister, or stone in a shoe may cause no pain at all. Second, it narrows blood vessels, which slows healing and makes infection more likely and more serious. A wound you cannot feel, that heals slowly, in a warm climate, is a dangerous combination.
A note on going barefoot
Walking barefoot indoors, in the courtyard, or in the mosque is common practice and a frequent cause of unnoticed injuries. If you have any loss of sensation in your feet, wear soft footwear at all times, including indoors.
The daily routine
- Look at both feet every day. Tops, soles, heels, and between every toe. Use a mirror on the floor, or ask a family member, if you can't see the soles easily. This takes under a minute and prevents more harm than anything else on this list.
- Wash with lukewarm water. Test the temperature with your hand or elbow, never your feet, since reduced sensation can mask scalding.
- Dry thoroughly, especially between the toes. Trapped moisture leads to fungal infection and skin breakdown.
- Moisturise the tops and soles, but not between the toes.
- Check inside your shoes before wearing them for stones, grit, or a folded insole.
Nails and skin
- Cut nails straight across, not curved down at the corners, to avoid ingrown nails
- Do not cut or shave corns and calluses yourself, and avoid corn-removing chemical plasters. Have them treated professionally instead
- Never use a hot water bottle or heater directly on your feet
Footwear
Shoes should be closed, well-fitting, and soft-soled, with enough room at the toes. Buy shoes in the evening, when feet are slightly larger. Break new shoes in gradually, an hour a day at first, and check your feet after each wear.
Warning signs that need medical attention
See a doctor promptly for any of the following:
- Any cut, blister, or sore that has not started healing within a few days
- Redness, swelling, warmth, or pus, which are signs of infection
- A change in the colour of the skin, especially blackening
- New numbness, tingling, or burning pain in the feet
- A foul smell from a wound
- Fever alongside any foot wound
An infected diabetic foot wound can worsen within days. Do not wait to see whether it settles on its own.
The two-minute daily foot check
Most diabetic foot care at home comes down to this short check. Tie it to a fixed point in your day, after wuzu at night or just before bed, so it becomes automatic.
- Soles: use a mirror on the floor, or ask a family member, and look for cuts, blisters, and cracks
- Between every toe: look for trapped moisture, whitened soft skin, or the peeling and itching of fungal infection
- Tops, heels, and ankles: look for redness, swelling, colour changes, and cracked heels
- Touch: feel for any spot noticeably warmer than the same spot on the other foot, an early sign of trouble brewing
- Nails: check the corners for ingrowing edges, thickening, or discolouration
- Shoes: run a hand inside each shoe before wearing it
Anything new gets watched daily. Anything not clearly improving within a couple of days gets shown to a doctor.
Do this, not that
| Do | Don't |
|---|---|
| Check both feet every day | Walk barefoot, indoors or outdoors |
| Moisturise the tops and soles | Use blades, razors, or corn caps on hard skin |
| Cut nails straight across | Soak feet in hot water |
| Wear clean cotton socks, changed daily | Ignore small cracks, especially on the heels |
| Check inside shoes before wearing them | Warm your feet on heaters or hot water bottles |
Which warning sign needs which urgency?
| Urgency | Signs |
|---|---|
| See a doctor this week | Redness that persists for days, a callus growing thicker, heel cracks that keep reopening, new tingling or burning |
| Same day, treat as an emergency | Any open wound or ulcer, blackening of the skin, redness spreading up the foot, pus or a foul smell, fever alongside any foot wound |
When in doubt, move it up a category. With diabetic feet, the cost of over-caution is a wasted trip; the cost of waiting can be permanent.
Footwear for Pakistani streets and homes
The chappal is comfortable, airy, and unfortunately one of the worst everyday options for a diabetic foot. It leaves the toes and sides exposed to stones, kerbs, and hot surfaces, the sole is often thin and hard, and the strap between the toes rubs exactly where skin breaks down most easily. If sensation in your feet is reduced, all of that damage can happen without you feeling any of it.
Look instead for closed shoes with a soft, cushioned sole, a wide toe box, no internal seams pressing on the foot, and a secure fit that does not slide. Wear clean cotton socks, and keep a pair of soft closed slippers for indoors. If you wear open footwear for wuzu and the mosque, check your feet when you get home.
When numbness means see a doctor
New or persistent numbness, tingling, or burning in the feet is not a normal part of ageing. It usually means the nerves are being affected by sustained high blood sugar, and it deserves a proper review rather than watchful waiting, because damaged nerves stop reporting the injuries that follow. The nerve symptoms, and the blood sugar control behind them, can be assessed and managed through an online consultation. An open, infected, or blackening wound is different: that needs in-person emergency care the same day, wherever you are.
Frequently asked questions
How should I check my feet at home every day?
Look at the tops, soles, heels, and between every toe once a day, using a mirror on the floor or a family member for the soles. You are looking for cuts, blisters, cracks, colour changes, and warm spots. The whole check takes about two minutes and prevents most serious problems.
Can I walk barefoot at home if I have diabetes?
It is safest not to, especially if you have any numbness in your feet. Walking barefoot indoors, in the courtyard, or in the mosque is how many diabetic foot injuries begin, because a small cut or a hot floor may not be felt. Wear soft, closed footwear at home.
Which footwear is best for diabetic patients in Pakistan?
Closed, soft, well-fitting shoes with a cushioned sole and room at the toes protect far better than chappals, which leave the foot open to stones and injury and often rub between the toes. Buy shoes in the evening, break them in gradually, and wear clean cotton socks.
When should numbness in the feet be shown to a doctor?
Any new or persistent numbness, tingling, or burning deserves a proper review, because it usually means the nerves are being affected by high blood sugar. Do not wait for pain, since damaged nerves often stop reporting pain. An open or infected wound needs in-person care the same day.
The underlying fix
Foot care routines reduce risk, but the root cause is sustained high blood sugar. Bringing your HbA1c into a safer range is what actually protects the nerves and blood vessels over the long term, which is the entire point of proper diabetes treatment.
