4 Stages of Diabetic Wound Healing: What to Expect

People with diabetes have a distinct set of health needs, and being vigilant about foot ulcers is near the top of that list. At Capital Podiatry Associates, we strive to educate our patients on how to keep their feet as healthy as possible, including those with diabetes.

So, let’s delve into the four stages of diabetic wound healing and how you can take action to address foot ulcers as quickly as possible with the right techniques. 

Why diabetes puts your foot health at risk

Diabetes is a condition that develops when your body either doesn’t produce sufficient insulin or cannot make good use of the insulin that’s produced. Insulin is a hormone that allows cells throughout your body to “accept” deliveries of glucose, which is a type of sugar that travels through your bloodstream to fuel your cells. 

Diabetes causes a wide range of problems within the body. Two of these — reduced nerve function and poor circulation — are specifically troubling for diabetic foot health. 

First, if your nerves don’t send proper pain signals to your brain, you may not realize you’ve developed a wound on your foot. Second, poor circulation means your wound won’t get the steady supply of blood it needs to facilitate healing. As your wound worsens, you might not even be aware of the problem, which then becomes a vicious cycle that can lead to serious outcomes, including amputation. 

The 4 stages of diabetic wound healing

Let’s take a look at how diabetic wounds heal, and how you can assist in that natural process. 

Stage 1: Hemostasis

This is the earliest stage of wound healing. It begins immediately after you sustain a foot wound, and involves blood vessels constricting, platelets collecting and releasing cytokines and growth factors that facilitate healing, and the formation of a fibrin clot to stop bleeding. 

Stage 2: Inflammation

During the inflammatory stage, which happens over the 2-7 days after you sustain a wound, your body sends an army of white blood cells to the area to begin destroying bacteria and clearing away dead tissue. More growth factors are released to boost the formation of the extracellular matrix, which is a structure that supports new tissue formation. 

Stage 3: Proliferation

At this point, your body begins building new tissue to close the wound and repair the damage. New blood vessels develop in the wound bed, and collagen begins to accumulate. This stage begins near the end of the inflammatory stage and can continue for several weeks. 

Stage 4: Maturation

This stage is defined by collagen remodeling, during which collagen proteoglycan molecules collect in thicker bundles to create stronger scar tissue. This part of the process will take longer for deep or large wounds, and can extend from six months to two years or more. 

How to support healthy wound healing

If you have diabetes, the single most important thing you can do to enhance wound healing is to perform daily foot checks. Identifying a wound as soon as possible enables you to clean the area and seek professional help. 

If you detect any break in your skin, no matter how seemingly minor, come see us right away for professional cleaning and care. Catching a wound in the early stages can help reduce the risk of negative outcomes. 

Should you develop a foot wound, we can advise you on how to keep the wound clean and care for it over time. We’ll also discuss the signs of infection or poor healing, letting you know when to schedule a return visit for wound assessment and care.
