Diabetes can cause the body to be unable to produce or use insulin, which may delay wound healing. It can lead to infections that are fatal or lead to amputations.

Diabetic wounds may heal slower, but improvement should be noticeable within a few weeks. If your wound shows no significant progress in healing within this time frame, it's crucial to consult a doctor promptly.

In this blog post, we will explore the healing time, different factors that can affect the healing time for wounds, especially those dealing with diabetes, and how we can speed up the healing process.

The healing time of a diabetic wound depends on several factors, including its severity, the patient's health, and wound management. Diabetes tends to affect circulation, neuropathy, and immunity, slowing wound healing.

High Blood Sugar Levels:

High blood sugar levels can delay the healing of diabetic wounds. A high glucose level in the blood can damage nerves and blood vessels. The longer the blood sugar levels remain high, the longer it takes for the wound to heal. Maintaining healthy blood sugar levels can accelerate healing.

Diabetes must be managed properly, including diet and exercise, to maintain blood sugar levels within a healthy range. Monitoring blood sugar levels and seeking medical attention for wound-related complications can prevent delays.

Poor Circulation:

Poor circulation can decrease the oxygen supply to the affected area, inhibiting the body's natural healing process. People with diabetes often have poor circulation, which contributes to slow wound healing. Prolonged wound healing in diabetics may negatively impact the immune response.

When circulation is poor, essential nutrients cannot reach wounds, hindering healing. Wound healing requires adequate circulation, and patients with chronic conditions affecting circulation may have a higher risk of slow healing. Medical attention and managing underlying conditions can improve circulation and speed up healing.

Immune System Deficiency:

Diabetes patient’s immune systems can be compromised, resulting in delayed wound healing because of fewer and less effective immune cells. This can lead to prolonged inflammation and an increased risk of infection. It takes diabetic wounds twice as long to heal as non-diabetic wounds.

Poor blood circulation and nerve damage in people with diabetes also contribute to delayed wound healing. Proper wound care and treatment can reduce the risk of complications and promote faster healing.

Wound Size And Depth:

The length of time it takes for a diabetic wound to heal

Wound size and depth are crucial factors in determining the healing time for diabetic wounds. The larger and deeper the wound, the longer it will take to heal. Blood vessel growth and wound healing are affected because glucose cannot be metabolized properly.

Usually, deep wounds are healed by debridement, which involves removing dead tissue. Also, large wounds may require more frequent dressing changes and additional wound care.

Infection And Complications:

Diabetic wounds are more likely to become infected, significantly slowing the healing process. Therefore, keeping the wound clean and appropriately dressed is crucial to prevent infection. Infection and complications can prolong the healing time of diabetic foot ulcers.

Diabetes can slow the healing process and make wounds more susceptible to infection. Infection can lead to more serious complications, such as cellulitis and osteomyelitis. Diabetic foot ulcer healing is highly affected by the treatment plan and severity of the wound.

Patient's Age And Overall Health:

The patient's age and overall health are crucial in healing diabetic wounds. The healing process may be delayed in older adults with cardiovascular disease, neuropathy, or impaired immunity. Diabetes can cause vascular and nerve damage, leading to slower healing.

Diabetic wounds can take 12 weeks to heal, longer if the patient has comorbidities or poor glucose control. Wound care, glycemic control, and comorbidities must be addressed for optimal healing.

Locations Of The Wound:

Diabetic Wound Healing Duration and Locations

The location of the wound also plays a crucial role in determining how long it takes to heal. Diabetic wounds on the legs and feet often take longer to heal than elsewhere because blood flow is reduced in these areas.

This lower blood flow means healing cells and nutrients take longer to reach the wound. The increased pressure on the foot from walking or standing may also impede the healing process.

Diabetic Wound Healing: 3 Phases

Diabetic wound healing involves three phases: the inflammatory phase (immune response and debris removal), the proliferative phase (tissue regeneration and angiogenesis), and the maturation phase (collagen remodeling and scar formation). These sequential stages collectively contribute to wound closure and tissue restoration.

Inflammatory Phase:

The Inflammatory Phase Of Diabetic Wound Healing

The inflammatory phase is the initial stage of wound healing, during which the body's immune system clears debris and pathogens. This phase typically lasts 1-5 days, but in diabetic wounds, it can last much longer because of impaired immune function.

Due to this prolonged inflammatory state, diabetic wounds can take significantly longer to heal and often develop into chronic wounds. Diabetes-related foot ulcers can take several months to years to heal, requiring aggressive interventions such as surgery and advanced wound care.

Diabetic wounds should be closely monitored, and aggressive treatment plans should be implemented early in the healing process to prevent chronic wounds.

Proliferative Phase:

During the proliferative phase of diabetes, growth factors stimulate cell division and collagen synthesis, which facilitates tissue repair and regeneration.

The duration of the diabetic proliferative phase varies from 4 to 21 days, depending on the severity of the wound and the individual's ability to heal.

Diabetes can lead to a prolonged proliferative phase and increased infection risk due to impaired blood flow, nerve damage, and compromised immune function.

Maturation Phase:

The maturation phase of wound healing involves remodeling tissue and strengthening the wound. Depending on the severity and location of the wound, this phase typically lasts between 21 days and 2 years.

Deficient maturation factors cause a delay in healing and an increased risk of chronicity during the maturation phase of diabetic wounds. Diabetic wounds heal in different amounts of time, depending on the patient's condition and wound care.

Treatment Applied To The Wound For Healing:

A diabetic wound heals at a different pace depending on several factors, including severity, overall health, and treatment effectiveness.

  • Clean the wound thoroughly with mild soap and water.
  • Apply an antibiotic cream or ointment to prevent infection.
  • Cover the wound with a sterile dressing or bandage.
  • Elevate the affected area to reduce swelling and promote blood flow.
  • Manage blood sugar levels through diet, exercise, and medication.
  • Use specialized wound dressings, such as hydrocolloids or foam dressings, to promote healing.
  • Undergo debridement and the removal of damaged tissue if necessary.
  • Hyperbaric oxygen therapy can accelerate healing by increasing oxygen flow to the wound.

Physical Activity And Lifestyle Choices:

A diabetic wound can also take longer to heal because of physical activity and lifestyle choices. Physically active diabetics can heal faster than those who don't exercise or consume unhealthy foods.

Taking too much alcohol, smoking, and not sleeping enough causes the body to heal wounds more slowly. The physical activity and lifestyle choices of diabetic patients must be carefully monitored.


Diabetic wound healing time is influenced by various factors, including the size and location of the wound, the treatment applied, and lifestyle choices.

Previously untreated wounds will take longer, and early intervention is recommended. Effective wound care practices and a healthy lifestyle can minimize the time required for healing.

Diabetic patients need to take good care of their wounds and follow a consistent wound treatment plan to prevent further complications. Further research is needed to continue advancing treatment options and improving wound healing outcomes for diabetic patients.

I am a passionate traveler, as if traveling were my full-time job. I like to change my surroundings and environment, like changing desktop wallpaper. Nature increases the concentration in my writing, which helps brainstorming flow in my blood. I have a cat named Kitana. She is the most desperate about traveling, more than any other cat. How do I know? If I miss any tour in any week, she literally destroys my clothing with her wolverine nails.

I and my cat also participate in extreme activities like surfing, biking, hill tracking, paragliding, boating, etc. She was always there in my accidents, injuries, and stitches. She always sits on my lap when it hurts me most. The funniest part is that she has experienced all my tattoos. She sleeps on my blanket when I go through any painful experience.

My hobbies and lifestyle added many pain and injuries to my life. That is why I have a lot of experience in dealing with different levels of pain and burn. It influenced me to become a pain expert and share primary suggestions to handle any unwanted situations that hurt.


  • Can You Distinguish Between Diabetic Wound Healing and Infection?

    The healing and infection of diabetic wounds can be distinguished. In diabetic wound healing, there may be delayed healing, decreased collagen synthesis, and increased inflammatory response.

    Infections, on the other hand, may show signs of redness, warmth, swelling, and tenderness around the wound. There may be discharge or pus from the wound, odor, and fever.

  • How Do Wound Healing Phases Differ Between Diabetics and Non-Diabetics?

    Diabetics experience different wound-healing phases due to an impaired immune system and high blood sugar levels. In diabetics, there may be a delay in the inflammatory phase and a decrease in angiogenesis and collagen synthesis during the proliferative phase.

    Moreover, the remodeling phase may be altered, leading to a weaker healed wound. Non-diabetic patients, on the other hand, tend to have faster and more efficient wound healing.

  • Why Do Diabetic Patients Have Delayed Wound Healing and Higher Infection Rates?

    Due to chronic hyperglycemia, diabetes patients have slower wound healing and a higher infection rate. High blood sugar levels lead to decreased angiogenesis and collagen synthesis and impaired communication between cells involved in wound healing. Moreover, diabetic patients have reduced inflammatory responses, making them susceptible to harmful bacteria invading the wound and causing infections.

  • Is It Better To Cover Or Leave Uncovered Diabetic Wounds For Faster Healing?

    Cover diabetic wounds with sterile dressings to prevent infection and promote faster healing. If an infection is present, leave the wound uncovered and keep it dry to avoid promoting bacterial growth.

    When deciding whether to cover or leave the wound uncovered, consider factors like wound size, depth, location, and the patient's overall health.
