Why Do Diabetic Patients Often Develop to Diabetic Foot Ulcers ?

July 11 / 2025

 

 

 

     Diabetes remains a silent yet formidable disease. A single diagnosis can trigger a cascade of related health conditions, much like ripples expanding across water when a stone is cast. Among the complications, diabetic foot ulcers often raise questions—why do they occur specifically at the feet, why do they heal slowly, and why do they often begin with numbness and a loss of sensation? What are the underlying causes of these symptoms?

 

Foot Complications in Diabetic Patients

     Diabetic foot ulcers are complications that result from arterial occlusion. In some cases, infection may also be present, further impeding blood circulation to various parts of the body. This condition frequently manifests in the legs and is typically characterized by three main symptoms:

 

Common Symptoms of Diabetic Foot Ulcers

1. Infection

     Bacterial infections slow the healing process and can result in severe inflammation. If wounds are not properly cared for, the infection may enter the bloodstream, leading to serious systemic complications.

 

2. Inflammation

     The affected foot or area around the wound often becomes red and swollen before darkening to a deep green hue, accompanied by intense pain. In most cases, the wound is also infected and fails to heal within four weeks.

 

3. Tissue Loss (Gangrene)

     When blood vessels are obstructed, the lack of oxygenated blood can result in chronic wounds. In severe cases, the infection and inflammation may spread, ultimately leading to the loss of the affected limb.

 

 


Diabetic wounds often develop in areas with poor blood circulation and nerve damage. The feet are particularly vulnerable, as they are subject to constant pressure and friction.

 

 

 

Why Do Diabetic Wounds Commonly Occur on the Feet?

1. The Feet Bear the Body's Weight

     The feet are the farthest from the heart and bear vertical pressure from the body's weight. As wounds develop, the feet are often the first affected due to their constant use in standing, walking, running, and jumping. Diabetic patients often experience numbness and reduced sensation in the feet, leading them to unknowingly aggravate wounds. Some may have foot deformities, abnormal sweating, or other associated conditions.

 

2. Dry and Easily Cracked Skin

     Diabetic neuropathy can result in diminished sensation. As patients walk, the repeated pressure and friction cause the skin to dry and crack, creating entry points for pathogens.

 

3. Infection

     Bacterial infections slow the healing process and may cause progressive inflammation, leading to swelling, tissue necrosis, and unpleasant odors. Improper wound care can increase the risk of further complications.

4. Improper Footwear

     Standard shoe sizes may not suit diabetic patients, as ill-fitting shoes—especially those made of hard leather—can compress and rub against the feet, creating wounds. Swelling during walking can further restrict footwear, worsening the issue.

 

Treatment of Diabetic Foot Ulcers

Medical Intervention

Physicians begin by assessing the condition and interviewing the patient. Diagnostic tests follow, leading to a treatment plan that may include pus drainage, antibiotic therapy, or surgery.

 

  • Physicians may open the wound to drain pus and remove necrotic tissue.
  • The use of antibiotics is determined at the physician's discretion.
  • Angioplasty or vascular surgery may be performed if blood vessel blockage is detected.
