The difficult thing about the diabetic foot is that it often does not hurt when it should. A wound that would make anyone else limp to a clinic can sit unnoticed for days — which is exactly why prevention and early action matter so much.
Watch: Protecting a Diabetic Foot
Why Diabetes Puts the Feet at Risk
Two changes make the difference. Over time, high blood sugar can damage the nerves (neuropathy), so the foot loses its warning system — you may not feel a stone in your shoe, a burn, or a blister forming. At the same time, circulation to the foot can narrow, so when an injury does happen, it heals slowly and is more prone to infection. Put those two together and a minor problem can escalate before you are even aware of it.
Warning Signs Worth Acting On
- Any cut, blister, or ulcer that is slow to heal — or is not healing at all.
- Numbness, tingling, or burning in the feet, or a loss of feeling.
- Redness, warmth, swelling, or discharge — these can signal infection.
- A sudden warm, swollen foot without an obvious injury (this can be a Charcot foot).
- Changes in shape, new pressure points, corns, or thick calluses.
- Cold, pale, or bluish skin, or blackening of a toe.
Charcot Foot — The One People Miss
A Charcot foot can begin as a warm, swollen foot that is not especially painful, and it is easily mistaken for a simple sprain or infection. Left unrecognised, the bones can weaken and the foot can gradually change shape. A sudden hot, swollen diabetic foot should always be checked early — catching it in time changes everything.
Simple Daily Habits That Prevent Most Problems
- Look at your feet every day, including the soles and between the toes — use a mirror or ask for help if you cannot see well.
- Wash and dry gently, especially between the toes, and moisturise dry skin (but not between the toes).
- Never walk barefoot, even at home; check inside shoes for grit or rough seams before wearing.
- Choose well-fitting, soft footwear; get corns and calluses dealt with properly, not cut at home.
- Keep your blood sugar under control — it is the single biggest factor in foot health.
When a Wound or Ulcer Appears
A diabetic foot ulcer is not something to treat at home with wait-and-watch. Proper care — taking pressure off the wound, treating infection, ensuring the blood supply is adequate, and sometimes minor surgery to help it heal — is what protects the foot. The great majority of diabetic feet can be saved when problems are managed early and correctly. The dangerous path is the wound that is ignored, or treated too late.

Frequently Asked Questions
Why is a diabetic foot considered dangerous?
Diabetes can reduce both feeling and blood supply in the feet, so injuries go unnoticed and heal slowly. A small wound can then become a serious infection before it causes obvious pain.
How often should I check my feet?
Every day. Look at the soles and between the toes for cuts, blisters, colour changes, or swelling. Daily checks catch the problems that neuropathy would otherwise hide.
Can a diabetic foot wound heal without amputation?
In most cases, yes — when it is treated early and correctly. Offloading pressure, controlling infection, ensuring good blood flow, and timely care are what save the foot. Amputation becomes a risk mainly when problems are left too late.
What is a Charcot foot?
It is a serious condition where the bones of a diabetic foot weaken and the foot can change shape. It often starts as a warm, swollen foot that is not very painful, so a sudden hot, swollen diabetic foot should be checked early.
I have numbness in my feet — should I be concerned?
Numbness in diabetes means your feet may not warn you about injuries, so extra care and regular checks become important. It is worth having your feet assessed and a prevention plan set up.
