Everything You Need to Know About Diabetic Foot Wounds

Diabetes is a chronic condition that affects millions of people worldwide, and it can have severe consequences for foot health. Diabetic wounds, including ulcers, neuropathic wounds, and ischemic wounds, pose significant challenges and require specialised treatment. In this blog, we will explore the various types of diabetic wounds and delve into diabetic foot ulcer treatment options. By understanding these aspects, individuals with diabetes and healthcare professionals can work together to prevent and manage diabetic wounds effectively.


Understanding Diabetic Wounds


A. Definition and Causes

Diabetic wounds are a common complication among individuals with diabetes. They result from a combination of factors, including neuropathy and vascular disease. Neuropathy, characterised by nerve damage, reduces sensation in the feet, making it difficult to detect injuries or pressure points. Vascular disease affects blood flow to the extremities, impairing wound healing.


B. Types of Diabetic Wounds

Here are the different types of diabetic wounds:


Diabetic Foot Ulcers

Diabetic foot ulcers are the most common types of diabetic wounds. They are open sores or wounds that develop primarily on the feet. They typically occur due to a combination of neuropathy, trauma, and excessive pressure on the foot.  Ulcers commonly appear on pressure points such as the balls of the feet, heels, and sides of the feet. Prompt detection, assessment, and diabetic foot ulcer treatment are crucial to prevent complications such as infection and amputation.


Diabetic Neuropathic Wounds

Neuropathy is a significant contributor to foot wounds in diabetes. Nerve damage could lead to a loss of protective sensation, making individuals unaware of injuries or abnormal pressure.  Neuropathic wounds typically manifest as calluses, corns, or blisters, and they require specialised care to avoid infection and further damage.


Ischemic Wounds

Ischemic wounds occur due to inadequate blood supply to the feet, primarily caused by peripheral artery disease (PAD). Diabetes can exacerbate the effects of PAD, leading to tissue damage and non-healing wounds.  Ischemic wounds are characterised by poor circulation, delayed healing, and increased risk of infection. Multidisciplinary care involving vascular specialists is often necessary for managing ischemic wounds effectively.


Diabetic Foot Ulcer Treatment


A. Wound Assessment and Classification

A comprehensive wound assessment is crucial for determining the appropriate diabetic foot ulcer treatment approach. Healthcare professionals evaluate the size, depth, and characteristics of the wound, as well as factors such as infection and perfusion. Various wound classification systems, such as the Wagner and University of Texas systems, help guide treatment decisions.


B. Wound Care Strategies


Debridement - Debridement involves the removal of dead, contaminated, or non-viable tissue from the wound bed. It promotes wound healing by facilitating the growth of healthy tissue. Debridement methods include sharp debridement, enzymatic debridement, autolytic debridement, and mechanical debridement. Regular debridement sessions are necessary to maintain a clean wound bed.


Dressings and Topical Treatments - Choosing appropriate dressings is essential for optimising wound healing. Various types of dressings, such as foam, hydrocolloid, and alginate dressings, serve different purposes based on the wound characteristics.  Advanced wound care products, including growth factors and antimicrobial dressings, can aid in healing and preventing infection. Healthcare professionals select dressings based on the stage and condition of the ulcer.


Offloading and Pressure Redistribution - Offloading techniques help reduce pressure on foot ulcers, allowing them to heal. Various devices, such as total contact casts, removable cast walkers, and orthotics, effectively redistribute pressure away from the wound. Proper footwear selection and modifications, such as custom-made shoes or insoles, play a vital role in preventing and managing foot ulcers.


Prevention and Self-Care


A. Foot Care Education


Proper education on foot care is paramount in preventing diabetic foot wounds. Individuals with diabetes should be informed about the importance of daily foot inspections. They should carefully examine their feet, including the areas between the toes and the soles, for any signs of redness, swelling, blisters, cuts, or calluses. Additionally, they should wash their feet daily with lukewarm water and mild soap, ensuring thorough drying, especially between the toes.


Moisturising the feet with a fragrance-free lotion or cream helps prevent dry skin and cracking. It is essential to remind individuals with diabetes to trim their toenails straight across and not too short to avoid ingrown toenails. Emphasise the significance of wearing well-fitting shoes and socks that provide cushioning and support.


B. Blood Sugar Control and Lifestyle Factors


Maintaining optimal blood sugar control is a crucial aspect of preventing diabetic foot wounds. Consistently monitoring blood glucose levels, adhering to prescribed medications, and following a healthy diet are key components of effective diabetes management. Encourage individuals to work closely with their healthcare team to develop a personalised diabetes management plan.


Lifestyle factors also play a paramount role in foot health. Smoking cessation is vital, as smoking restricts blood flow and impairs wound healing. Regular exercise, such as walking or low-impact activities, promotes circulation and overall well-being. Weight management is essential to reduce excessive pressure on the feet.


Encourage individuals to prioritise their self-care and seek prompt medical attention if they notice any changes in their feet, such as wounds, infections, or persistent pain. Engaging in open communication with healthcare professionals and attending regular podiatric check-ups ensures early detection and intervention, preventing the progression of foot complications.




Diabetic foot wounds, including ulcers, neuropathic wounds, and ischemic wounds, are significant concerns for individuals with diabetes. Understanding the causes, types, and treatment options for these wounds is crucial for prevention and effective management.  By prioritising foot health, adopting proper wound care strategies, and actively managing diabetes, individuals can reduce the risk of diabetic foot wounds and their associated complications. 


Regular communication and collaboration with healthcare professionals are essential for achieving the best outcomes and improving overall foot health in the diabetic population.
