This article explores why some wounds become slow to heal, looking at common underlying factors such as hidden infection, inflammation, and the body’s internal healing environment, and how a more supportive, integrative approach may help restore the natural healing process.

By Dr Catherine W. Dunne, MSc.D., RGN (GPN)

If you’ve ever had a wound that seemed to linger far longer than it should, you’ll know how frustrating it can be.

It starts small.
A cut. A graze. A surgical site.
Then weeks pass… and it’s still there.

For some people, especially those with diabetes, circulatory issues, or ongoing inflammation, wounds can become slow, stubborn, and difficult to manage.

But here’s the part many people are never told:

👉 Not all wounds fail to heal because of the skin.

Very often, the issue lies beneath the surface.

The Hidden Problem: Why Healing Gets Stuck

In clinical practice, delayed wound healing is usually linked to three key factors:

1. Persistent Low-Level Infection

Even when a wound doesn’t look obviously infected, bacteria can still be present.

These microbes don’t always behave in the way we expect.
They don’t just sit on the surface, they organise themselves.

2. Biofilm Formation (The “Invisible Shield”)

Bacteria can form what’s known as a biofilm, a protective layer that acts like a shield.

Inside this structure:

• bacteria become harder to kill
• standard treatments may struggle to reach them
• the wound remains in a prolonged inflammatory state

This is one of the main reasons wounds become chronic.

3. Ongoing Inflammation

When the body senses something isn’t right, it stays in “repair mode.”

But if that phase never switches off:

• healing slows
• tissue regeneration is impaired
• the wound can stall completely

Why Standard Treatments Don’t Always Work

Modern wound care is excellent in many ways, particularly with:

• advanced dressings
• infection control
• moisture balance

But even with the best care, some wounds:

• plateau
• re-open
• or simply refuse to progress

This is where we begin to look at adjunctive approaches, methods that support the body rather than replace standard care.

A Quietly Powerful Tool: Silver in Wound Care

Silver has been used in wound care for centuries.
In modern practice, it is commonly found in specialised dressings used in hospitals and community settings.

Its value lies in its ability to:

• reduce harmful bacteria in the wound
• interfere with how bacteria grow and spread
• support a cleaner environment for healing

This can be particularly helpful in wounds that appear clean but are not progressing.

More recently, there has been growing interest in colloidal silver, which contains very small (nano-sized) particles suspended in solution.

Research and clinical observation suggest it may:

• help reduce the number of bacteria present
• disrupt protective layers that bacteria form to shield themselves (known as biofilms)
• support a more balanced healing environment

Importantly, when used appropriately, it is considered an adjunct, meaning it works alongside standard wound care rather than replacing it.

A Holistic View of Wound Healing

From a holistic perspective, wound healing is never just about the skin.
It involves:

• circulation
• immune function
• how the body produces and uses energy, regulates blood sugar, and controls inflammation
• balanced inflammation response

And sometimes, small supportive interventions can help the body return to a natural healing state.

Final Thoughts

If a wound is slow to heal, it does not mean the body has failed.
It usually means something is getting in the way.

Understanding factors such as infection, biofilm, and inflammation can make a significant difference in how we approach care.
When appropriate, integrating supportive therapies alongside standard treatment may help support the healing process.

This article is intended to support understanding and awareness of wound healing and does not replace individual clinical assessment or care.
It usually means something is getting in the way of the natural healing process.

I hope you feel inspired. Look after your body, and it will keep you healthy.
