Diabetic Wound Care: Why Is Prevention So Important?

Diabetic foot ulcers are among the most common and serious complications of diabetes. They affect approximately 15% of people with diabetes and most frequently develop on the soles of the feet, particularly in areas exposed to prolonged pressure or friction.

This condition should never be underestimated. Up to 6% of people with diabetic foot ulcers require hospitalisation due to infection or other complications.

Even more concerning is that 14–24% of patients with this type of ulcer may require an amputation of part of their lower limb. Diabetic foot ulcers precede up to 85% of all diabetes-related amputations.

Who Is Most at Risk?

Diabetic foot ulcers can develop in anyone with diabetes, regardless of age or type of diabetes. However, certain groups face a higher risk, including:

• People who use insulin.

• People with diabetes-related kidney, eye or cardiovascular complications.

• People who have been living with diabetes for many years.

• People who are overweight, smoke or regularly consume alcohol.
  

Why Do Diabetic Foot Ulcers Develop?

Diabetic foot ulcers usually develop due to a combination of several factors:

• Neuropathy – Nerve damage caused by prolonged high blood sugar levels can reduce sensation in the feet, making it difficult to feel pressure, friction or minor injuries.

• Foot Deformities – Conditions such as hammertoes, bunions and other structural changes can alter how pressure is distributed across the feet.

• Poor Circulation – Reduced blood flow to the tissues can slow down wound healing.

• Irritation and Minor Injuries – Ill-fitting footwear, a small stone inside a shoe or a minor unnoticed injury can eventually develop into a serious ulcer.

• Duration of Diabetes – The longer someone has diabetes, the greater their risk of developing complications.
  

Vascular conditions, such as diabetic angiopathy or peripheral arterial disease (PAD), can further restrict blood flow to the tissues and delay wound healing.

Additionally, high blood sugar levels can weaken the body's ability to fight infections, significantly increasing the risk of serious complications.

Can Diabetic Foot Ulcers Be Prevented?

Yes. Research suggests that many diabetic foot ulcers can be prevented through appropriate preventive care.

The key measures include:

• Daily Foot Checks – Look for redness, blisters, skin changes, pressure marks, cracks or other unusual signs.

• Wearing Appropriate Footwear – Choose properly fitted, supportive footwear that provides enough room in both length and width.

• Using Diabetic Insoles – Specially designed insoles can help redistribute pressure and reduce stress on vulnerable areas of the feet.

• Regular Visits to a Podiatrist – A qualified specialist can assess the condition of your skin and nails, identify high-risk areas and provide preventive care.

• Proper Skin Care – Keep your feet moisturised and pay particular attention to dry or cracked skin. Avoid applying moisturiser between your toes.

• Blood Sugar Management – Maintaining blood glucose levels within your recommended target range supports wound healing and helps reduce the risk of complications.
  

What Should You Do If You Suspect a Foot Ulcer?

If you notice an open wound, redness, swelling, an unusually warm area or any discharge from your foot, contact a healthcare professional immediately.

Early assessment and appropriate treatment can significantly reduce the risk of serious complications.

Conclusion: Prevention Is the Best Approach

A diabetic foot ulcer is far more than a minor inconvenience. It is a serious condition that can lead to complications, including amputation.

The good news is that many diabetic foot ulcers can be prevented with appropriate care. Properly fitted footwear, good foot hygiene and regular professional foot examinations are essential parts of prevention.

Remember: Checking your feet every day and taking preventive measures can help protect your feet, your mobility and your long-term health.
