What Is Diabetic Foot and How to Prevent Serious Complications

Diabetes affects over 3 million Canadians and can lead to serious issues, including diabetic foot. At Ontario Vascular, many patients are surprised to learn that a simple sore or blister can lead to dangerous complications if left untreated.

What Is Diabetic Foot?

“Diabetic foot” refers to foot problems caused by diabetes-related nerve damage (neuropathy) and poor circulation. These issues can:

• Reduce feelings in the feet

• Delayed healing of wounds

• Increase the risk of infection

Even a small injury can develop into a foot ulcer or, in severe cases, lead to gangrene or amputation.

Early Warning Signs

Since nerve damage can reduce pain sensation, it’s important to look for signs such as:

• Redness, swelling, or warmth

• Wounds or sores that don’t heal

• Thickened or discoloured toenails

• Dry or cracked skin

• Foot shape or colour changes

• Numbness or tingling

Prevention Tips

✅ Check your feet daily. Look for cuts, blisters, or infections. Use a mirror or ask for help if needed.

✅ Control your blood sugar. Stable glucose levels promote better healing and circulation.

✅ Wear proper footwear. Use shoes designed for diabetes. Avoid walking barefoot.

✅ Trim nails safely. Cut straight across to prevent ingrown nails.

✅ Moisturize wisely. Keep feet soft, but avoid applying cream between the toes.

✅ Visit a vascular specialist. Regular exams and Doppler ultrasounds help detect circulation issues early.

When to See a Specialist

See a healthcare provider if you notice:

• A slow-healing wound

• Skin colour changes

• Coldness or numbness in the feet

Early evaluation can help prevent serious complications and protect mobility.

Consulting a licensed healthcare provider is essential to understand your treatment options and ensure safe care.
