Diabetic Foot Ulcers

What is a Diabetic Foot Ulcer (Sugar Sore)?

A diabetic foot ulcer is a wound occurring on the feet of individuals with diabetes that can be difficult and time-consuming to heal. Over time, high blood sugar levels damage the nerve and vascular structures. This leads to a loss of sensation and circulatory disorders in the foot, which can cause small injuries to grow unnoticed.

If diabetic foot ulcers are not controlled in the early stages, they can lead to serious infections, tissue loss, and, in advanced cases, consequences extending to surgical interventions. Therefore, early diagnosis and regular follow-up are of great importance.

Why Do Diabetic Foot Ulcers Occur?

Multiple factors play a role in the formation of diabetic foot ulcers. The most common causes include:

• Long-term high blood sugar levels

• Loss of sensation due to nerve damage (neuropathy)

• Circulatory disorders

• Pressure points and deformities in the foot

• Use of inappropriate footwear

• Unnoticed small cuts, cracks, or calluses

When these factors combine, foot ulcers can easily become chronic.

What Are the Symptoms of a Diabetic Foot Ulcer?

Diabetic foot ulcers can often be painless. This causes patients to notice the wound late. The most common symptoms are:

• Open sores or cracks on the foot

• Redness and swelling

• Discharge or foul odor

• Discoloration of the skin

• Fever and deterioration of general health in advanced stages

If these symptoms are noticed, an expert evaluation should be performed without delay.

How Are Diabetic Foot Ulcers Diagnosed?

The diagnostic process begins with a detailed clinical evaluation. During the diagnosis phase:

• Foot examination

• Circulation assessment

• Examination for signs of infection

• Imaging methods (when necessary)

Early diagnosis facilitates the treatment process and reduces the risk of complications.

Goals of Diabetic Foot Ulcer Treatment

The primary objectives in treating diabetic foot ulcers are:

• Ensuring the wound heals

• Controlling the risk of infection

• Preventing tissue loss

• Preserving foot functions

• Improving quality of life

The treatment process is planned according to the stage of the wound and the patient’s general health status.

Treatment Methods for Diabetic Foot Ulcers

Conservative (Non-Surgical) Treatments

• Wound care and regular dressing

• Pressure-offloading applications

• Infection control

• Regulation of blood sugar levels

• Use of appropriate shoes and insoles

Surgical Treatment In some advanced cases, cleaning of unhealthy tissues (debridement) or tissue repair may be necessary. Reconstructive surgical approaches can be applied to support wound closure and functional recovery.

How is the Treatment Planned?

When creating a treatment plan, the following are taken into account:

• The size and depth of the wound

• Infection status

• Presence of circulatory disorders

• The patient’s diabetes control

Diabetic foot ulcer treatment generally requires a multidisciplinary approach, and regular follow-up is critical.

Is It Possible to Prevent Diabetic Foot Ulcers?

Yes. A large portion of diabetic foot ulcers can be prevented with the right precautions. Preventive approaches include:

• Performing daily foot checks

• Keeping feet clean and dry

• Choosing appropriate footwear

• Regular blood sugar monitoring

• Never ignoring small wounds

These measures play a vital role in preventing serious complications.

Quality of Life and Diabetic Foot Ulcers

Diabetic foot ulcers can significantly affect a patient’s daily life and mobility. Long-term treatment processes can be challenging both physically and psychologically. With correct treatment, regular follow-up, and patient education, many patients can achieve wound healing and improve their quality of life.
