Diabetes can lead to various complications, one of the most serious being diabetic foot ulcers. These ulcers are open sores or wounds that occur primarily on the feet and are often the result of mechanical damage due to neuropathy (nerve damage) and sometimes due to poor blood flow to the foot. If left untreated, diabetic foot ulcers can lead to infections, gangrene, and even amputations. Effective management requires a comprehensive, integrated approach involving early detection, preventive care, and sometimes surgical intervention.
This article delves into the causes, types, and treatments of diabetic foot ulcers, emphasizing the importance of integrated care. The expertise of specialists like Dr. Sarvanan at Madurai Footcare Center, known for his personalized and advanced care, is vital in managing and healing these ulcers.
Understanding Diabetic Foot Ulcers
Diabetic foot ulcers occur due to prolonged high blood sugar levels, which damage the nerves and blood vessels initially both of which are significant contributors to the development of ulcers.
- Peripheral Neuropathy: High blood sugar damages the nerves in the feet, leading to a loss of sensation. This means a person may not notice small injuries, cuts, or pressure points that can evolve into ulcers.
- Poor Circulation (Vasculopathy): Diabetes also impairs blood flow, especially in the extremities. Reduced blood flow makes it difficult for wounds to heal, allowing even minor injuries to progress into serious ulcers.
Common Sites of Diabetic Foot Ulcers
Foot ulcers in diabetic patients can occur in various parts of the foot, with the most common types being in the forefoot region.
- Diabetic Forefoot Ulcers: This type of ulcer develops under the toes or on the balls of the feet, typically due to repeated pressure or trauma.
- Heel Ulcers: These are more common in bedridden patients where prolonged pressure on the heels causes sores especially over the outer side of the foot.
- Midfoot Ulcers: These ulcers may develop due to neuropathy-induced deformities like Charcot foot, where the bones in the midfoot become misaligned.
Causes and Risk Factors
INJURY is the main cause for the development of foot ulcers.
If the patient is taking proper Foot Care avoiding injury in spite of having neuropathy or Vasculopathy the chances of getting foot ulcers are very less.
Several factors increase the risk of developing ulcers on diabetic feet, including:
- Neuropathy: As discussed, nerve damage makes it difficult to feel injuries or pressure points.
- Inadequate Footwear: Wearing ill-fitting shoes increases the likelihood of pressure and friction that can lead to ulcers, especially on the toes and forefoot.
- Poor Blood Sugar Control: Chronically high blood sugar levels delay healing and increase infection risk.
- Smoking: Smoking impairs circulation, further complicating wound healing.
- Previous Ulcers or Amputations: Patients who have had ulcers before are more prone to developing them again.
The Role of Integrated Care in Managing Diabetic Foot Ulcers
Diabetic foot ulcers require integrated care, which means addressing not only the ulcer but also the underlying causes of diabetes, circulation issues, and neuropathy. An integrated approach involves a multidisciplinary team, including podiatrists, Diabetologists,vascular specialists, endocrinologists, and diabetic educators. The goal is to provide comprehensive care that covers all aspects of the condition.
1. Preventive Footcare
Preventive care is crucial for reducing the risk of foot ulcers. Diabetic patients should:
- Check their feet daily for cuts, sores, or redness.
- Wear properly fitting shoes that minimize pressure points.
- Keep blood sugar levels within the target range.
- Maintain good foot hygiene and moisturize to prevent dry, cracked skin.
2. Wound Care and Management
Once a foot ulcer has developed, proper wound care is essential. This involves:
- Wound Cleaning (Debridement): The removal of dead or infected tissue is a common treatment for diabetic ulcers to help the wound heal faster and reduce the spread of infection.
- Pressure Offloading: This involves reducing pressure on the ulcerated area through the use of bulky dressings, custom orthotics, specialized footwear, or, in severe cases, total contact casting.
- Amputation: In severe cases where gangrene has developed, partial or complete amputation may be necessary to save the patient’s life.
In more advanced cases, when non-surgical treatments fail, surgical intervention becomes necessary. Special procedures may include:
- Revascularization: Restoring blood flow to the foot through procedures like bypass surgery or angioplasty, especially for patients with peripheral arterial disease.
- Foot Reconstruction: Surgery may be required to correct deformities caused by neuropathy, such as in Charcot foot.

FAQ’s
What are the first signs of diabetic foot ulcers?
Diabetic patients will develop nerve damage first then comes the formation of callus in the high-pressure areas of the foot, usually in the Great toe region followed by the ball of the foot. Then the callus will get thickened and then upon continued walking , the CALLUS breaks and forms an ulcer.
How to identify the development of infection in diabetic foot ulcers?
The development of ulcer is different from development of an infection. Early signs of an infection in a diabetic foot ulcer include redness, swelling, and the appearance of an open sore or blister on the foot, especially under the toes or forefoot.
How often should a diabetic patient check their feet?
Diabetic patients should check their feet DAILY for any cuts, sores, blisters, or changes in skin color or temperature. Early detection is crucial in preventing small injuries from becoming severe ulcers.
What are the best practices for treating diabetic foot ulcers at home?
Basic at-home care includes:
- Keeping the wound clean and dry.
- Changing dressings as instructed by a healthcare professional or utilization of home care services.
- Using prescribed antibiotics if there is any sign of infection.
- Offloading pressure from the ulcerated area by using bulky dressings, orthotics, or specially designed footwear.
However, it’s essential to consult a doctor for any open sore to avoid complications.
Can diabetic foot ulcers be completely cured?
Yes, with timely intervention and proper management, diabetic foot ulcers can heal completely. However, patients must continue preventive measures to avoid recurrence, as they are at higher risk for future ulcers.
When should someone with a diabetic foot ulcer see a doctor?
you should see a doctor immediately. Delaying treatment increases the risk of complications, including infection and gangrene.
